Common AC Problems Every Homeowner Should Know (And When to Call a Pro)

Common Phoenix AC Problems and When to Call for Help

Common AC problems in Phoenix can quickly turn into major headaches when summer temperatures soar. A working air conditioner is a requirement in the Valley, and extreme heat pushes cooling systems to their limits. When something goes wrong, the effects are immediate.

Understanding what’s happening inside your AC and knowing when it’s time to get help can make the difference between a simple fix and a costly breakdown. In this guide, you’ll learn which common AC problems Phoenix homeowners face, what you can check yourself, and when it’s best to call a professional.

Weak Airflow or No Cool Air

If your AC is running but your home still feels warm or stuffy, airflow may be the issue. These are the most common causes:

Clogged air filters
Refrigerant leaks
Blocked vents or ductwork
A failing blower motor

In Phoenix’s desert heat, even mild airflow problems can quickly make your home uncomfortable. They also signal that your system may be working harder than it should, which can lead to bigger issues if left unchecked.

Odd Noises and Unusual Smells

Air conditioners make some noise, but new or strange sounds are often signs of a deeper problem:

Banging or clanking may indicate a loose or broken part
Hissing could suggest a refrigerant leak
Buzzing often points to an electrical issue

Unusual smells also deserve attention:

Musty odors may be caused by mold inside ducts or on the evaporator coil
A burning smell could indicate motor failure or electrical damage

If you notice persistent noises or odors, it’s a good idea to turn off your system and schedule a diagnostic.

AC Turning On and Off Frequently

One of the common AC problems Phoenix homeowners face is short cycling, where the air conditioner starts and stops more often than normal. This constant cycling puts strain on your system and reduces efficiency. Typical causes include:

A miscalibrated thermostat
Dirty condenser coils
Refrigerant imbalances
An oversized unit for the space

In a climate where ACs run for long hours, short cycling adds unnecessary wear and can shorten the life of your equipment.

Rising Energy Bills Without a Clear Reason

If your cooling costs spike but your usage hasn’t changed, your system may be losing efficiency. Some typical reasons include:

Dirty air filters or coils
Aging or worn-out components
Low refrigerant
Air leaks in the ductwork

Higher energy use often means your AC is struggling to keep up. That affects both comfort and cost.

Clear leaves or debris around the outdoor unit
Reset thermostat settings and replace the batteries

These basic steps can often resolve minor issues, but if you’re still experiencing any of these common AC problems, it’s time to call in a professional.

Why Regular HVAC Maintenance Makes a Difference

Phoenix’s dry, dusty climate creates unique challenges for HVAC systems. Air conditioners run hard for months, and even minor buildup can affect performance. That’s why seasonal maintenance is so valuable.

Benefits of regular ac tune-ups include:

Catching small issues before they become major repairs
Improving efficiency and lowering energy costs
Extending the lifespan of your equipment
Reducing breakdowns during the hottest months

If it’s been a while since your last service, Wolfgang’s offers professional AC maintenance to keep your system running reliably all season long.

What You Need to Know About New HVAC System Cost in Arizona

If you live in Arizona, you know just how extreme the temperatures can get, from scorching summer highs to chilly desert nights. To stay comfortable year-round, having an efficient and reliable HVAC system is non-negotiable. But when it comes time to install a new one, you’re probably wondering: what’s the actual new HVAC system cost in Arizona?

In this guide, we’ll walk through average pricing, cost variables, efficiency standards, and what you need to consider before investing. By the end, you’ll be equipped to make an informed decision that fits your comfort needs, and your budget.

Understanding Efficiency Standards in Arizona

When shopping for a new HVAC system, efficiency should be a top priority. Arizona requires all new systems to meet a minimum SEER rating of 15 (Seasonal Energy Efficiency Ratio). This is especially important in a climate that puts HVAC systems to the test nearly year-round.

Additionally, many units must be ENERGY STAR® certified to qualify for federal tax credits, local utility rebates, and other incentives. Investing in an energy-efficient system might cost more upfront, but it typically reduces long-term utility expenses.

A knowledgeable HVAC contractor should help you choose a system that not only meets Arizona’s codes but also helps you capitalize on available incentives, ultimately helping reduce your total HVAC system cost over time.

Average New HVAC System Cost in Arizona

While exact pricing depends on your home and preferences, the average cost of a new HVAC system in Arizona ranges from $3,000 to $7,000. This includes both the air conditioning and heating components of a split system, which is the most common setup in the region.

Here’s a general breakdown of what influences pricing:

Basic units (lower SEER ratings): $3,000–$4,000
Mid-range systems (SEER 15–17): $4,500–$6,000
High-efficiency systems (SEER 18+): $6,000–$7,500+

Homes with more square footage will require more powerful units, which naturally increases the cost. Similarly, advanced features like smart thermostats, variable-speed motors, and zoning capabilities will raise the price but improve long-term performance and comfort.

Key Factors That Impact Your HVAC Installation Cost

1. System Size

HVAC systems are not one-size-fits-all. Your contractor will perform a load calculation to determine the appropriate tonnage based on your home’s square footage, insulation, windows, and other variables. An undersized system may cost less initially but will under-perform and wear out faster. Conversely, an oversized unit can short-cycle, wasting energy and reducing comfort.

2. Type of System

There are several types of HVAC systems to choose from:

Split Systems (standard): Common in Arizona, good balance of cost and performance.
Packaged Systems: All-in-one units, often used in smaller homes or mobile units.
Ductless Mini-Splits: Great for additions or homes without ducts, but can be more expensive per zone.
Heat Pumps: Offer both heating and cooling, particularly efficient in mild winter climates like Arizona.

Each type has a different upfront cost and long-term maintenance profile that affects your total HVAC system cost.

3. Installation Complexity

Installation costs can vary widely depending on whether:

Ductwork needs replacement or repair
The system location (attic, crawlspace, etc.) is difficult to access
Electrical or structural modifications are needed

Quality installation is key, cutting corners may lower initial costs but often leads to inefficiency, discomfort, or repairs down the road.

4. Labor Rates and Permits

Licensed HVAC contractors charge based on experience, licensing, and demand in your area. Permits may be required by your local jurisdiction and will be included in the final quote.

Why the Right HVAC Contractor Matters

Finding a licensed, experienced contractor is crucial. An improperly installed unit can reduce efficiency by up to 30%, leading to higher utility bills and a shortened system lifespan.

A good contractor will:

Provide a detailed quote
Perform a Manual J load calculation
Walk you through system options
Handle rebate and permit paperwork
Offer a satisfaction or performance guarantee

At Wolfgangs, we pride ourselves on delivering high-quality HVAC installations that meet Arizona’s climate demands and efficiency codes.

The Long-Term Value of Investing in a New HVAC System

Although the new HVAC system cost may feel steep, consider it an investment in comfort, air quality, energy efficiency, and property value. With proper maintenance and a high-efficiency unit, most systems can last 15 to 20 years and pay for themselves over time through lower energy bills and fewer repairs.

Plus, installing a new system ahead of extreme weather seasons ensures you’re never left scrambling when your old unit breaks down.

The 5 Best Rooms For Ductless A/C

Are you looking for an efficient and cost-effective way to keep your home cool this summer? Consider installing a ductless A/C unit. This type of air conditioning system has become increasingly popular in recent years because it is a great way to keep a single room or area of your home comfortable and energy-efficient. In this blog post, we’ll explore the best rooms to utilize a ductless A/C unit and why they are ideal for keeping your space cool.

Living Rooms

When it comes to choosing the best room in your home for a ductless A/C unit, the living room is a great place to start. A ductless A/C unit will be able to provide efficient cooling to this room as well as provide more targeted cooling so that certain parts of the room stay cooler than others. This is especially helpful if you have large furniture pieces like a sofa or entertainment center that tend to trap heat. Additionally, if you have an open floor plan, you can use a ductless A/C unit to cool both your living room and dining room simultaneously. The multiple-zone capability of these units allows you to customize the temperature in each room, which can help you save energy by only cooling the parts of your home that you are actually using. Furthermore, ductless A/C units are fairly easy to install and can be done without having to install ducts in your home. This makes them a great choice for any living room.

Bedrooms

When it comes to cooling down bedrooms, a ductless A/C unit is an ideal choice. They can be installed in spaces where traditional air conditioning systems might not fit, making them great for small and large bedrooms alike. Ductless units are also quieter than window air conditioners, meaning you won't have to worry about the loud noise disrupting your sleep. With the ability to adjust temperatures in each room, you can make sure your bedroom is always the perfect temperature for sleep. Plus, because they're energy-efficient, you won't have to worry about skyrocketing electricity bills. Investing in a ductless A/C unit for your bedroom could be the perfect way to keep cool this summer.

Kitchens

When it comes to keeping your kitchen cool during the summer months, a ductless air conditioner can be a great solution. The main benefit of installing a ductless AC in your kitchen is that it can help keep the air fresh and free of food odors. Additionally, with its adjustable fan speed, you can keep the temperature at a comfortable level while also controlling humidity. It's also important to note that a ductless unit can help reduce your energy bills as it uses less electricity than traditional air conditioning systems.

Ductless air conditioners are typically easy to install and don't require any complicated wiring. All you need is an exterior wall to mount the unit on. Most models come with their own remote control, allowing you to easily adjust settings from anywhere in the room. When choosing the right model for your kitchen, consider its BTU rating to ensure it can adequately cool the area. Installing a ductless air conditioner in your kitchen will not only help keep the space cool and comfortable but will also help improve the air quality and reduce your energy costs. It's a great way to make your kitchen more enjoyable during the summer months!

Home Offices

Working from home can be a great way to stay productive and comfortable, but if your office is an unpleasantly hot environment, it can be difficult to stay motivated. One great solution is to install a ductless A/C unit in your home office. Ductless A/C units are small and efficient, making them a great choice for smaller rooms like home offices. They don’t require extensive installation or complicated ductwork, so you can have cool air circulating through your workspace in no time.

Garages

Garages can sometimes be a tricky space to keep cool. They often lack the insulation and structure of other rooms, making them more prone to temperature extremes. Fortunately, ductless A/C units are an ideal option for garages. Not only are they extremely energy-efficient, but they are also quiet and easy to install. The best part about using a ductless A/C unit for your garage is that it will not take up too much space. In fact, many models are designed to be small enough to fit in tight spaces. Plus, since they don’t require any permanent installation, you can easily move them from room to room as needed.

Ductless A/C units offer a great way to cool your Arizona home without the hassle of installing a traditional air conditioning system. They are especially beneficial for small rooms that would otherwise be difficult to cool. Living rooms, bedrooms, kitchens, home offices, and garages are all excellent candidates for a ductless A/C unit. With their easy installation and efficient operation, these systems provide a great way to keep your home cool and comfortable all summer long. Ready to install a ductless system?

How Do The New HVAC Requirements Affect Arizona Homeowners?

Did you know The Department of Energy (DOE) has passed new HVAC requirements that went into effect on January 1, 2023? Make sure you are aware of these new regulations, especially if you're thinking of replacing your HVAC system. All new systems installed after January 1, 2023, must comply with stricter guidelines for energy efficiency, testing, and certifications. So, you may be thinking: how does this impact me? Let our team explain below.

Why Are These HVAC Requirements Changing?

Every six years, The Department of Energy updates its HVAC requirements in an effort to reduce energy consumption in the United States. These updates ensure each system is current and efficient for homeowners. Each region of the U.S. has specific standards it must follow, and Arizona is no exception. Being aware of these changes ensures you're making informed choices, especially if you're planning a system upgrade.

What Are the New HVAC Requirements in 2023?

These updated HVAC requirements took effect on January 1, 2023. All HVAC systems installed after this date must have a SEER rating of at least 15. Currently, the minimum required SEER rating is 14. This means you’ll likely pay more upfront for a new system beginning in 2023. However, the trade-off is significant: higher efficiency, reduced energy bills, and a longer-lasting HVAC system.

Though the initial investment may be greater, the long-term savings and improved performance make the new systems a smart investment.

Do I Need to Update My Current System to Meet HVAC Requirements?

No, you do not. Existing systems that were installed prior to 2023 are grandfathered in and do not need to meet the new HVAC requirements. However, any new system purchased and installed after the effective date must comply with the updated SEER guidelines.

If you're already considering replacing your HVAC system, doing so before or shortly after the changes can help you avoid the immediate price increase associated with newer, more efficient models.

Benefits of a Ductless HVAC System For Your Arizona Home

Have you ever considered installing a Ductless HVAC System in your home? Also known as a mini-split system, a ductless HVAC system offers a modern alternative to traditional forced-air systems by eliminating the need for ductwork. As energy efficiency and indoor air quality become higher priorities for homeowners in Arizona, more people are realizing the many advantages of a Ductless HVAC System. From cost savings to cleaner air, here are the top reasons why this option may be the best fit for your home.

1. Saves You Money

A key benefit of a Ductless HVAC System is its ability to lower monthly energy bills. Ductless systems are designed to operate more efficiently than traditional HVAC systems, and they use less energy to deliver the same (or even better) results.

According to the U.S. Department of Energy, Energy Star certified mini-split units use up to 60% less energy than conventional electric heating systems. That’s a significant reduction in energy use, translating to noticeable savings on your utility bills.

Additionally, you can install ductless units only in the areas of your home that need cooling or heating the most, avoiding energy waste in unused rooms.

2. Improves Indoor Air Quality

Your air ducts collect dust, debris, mold, and pet dander over time, especially if they’re not regularly cleaned. That buildup is then circulated through your home whenever the HVAC system runs.

One of the major advantages of a Ductless HVAC System is that it bypasses ductwork altogether. Without ducts, there’s no opportunity for allergens and pollutants to collect and recirculate, which helps improve your indoor air quality. Most ductless systems also come with advanced multi-stage filtration features, giving you even cleaner, fresher air throughout your home.

3. Takes Up Less Room

Ductless HVAC systems are compact and flexible in terms of placement. Instead of taking up closet space or requiring large vents and duct chases, mini-split units can be mounted high on walls, suspended from ceilings, or even recessed for a more discreet appearance.

This is a big benefit of ductless HVAC systems for smaller homes, apartments, and older properties where space is at a premium, or where installing new duct-work would be too invasive or expensive. The sleek, modern design of ductless units helps them blend in with your interior, preserving your home’s aesthetics.

4. Gives You More Control Over Comfort

Tired of the family thermostat wars? Another significant advantage of ductless HVAC systems is the ability to create “zoned” comfort. Each indoor unit operates independently, allowing you to heat or cool specific rooms to your preference without affecting the rest of the house.

This means each family member can set the temperature to their liking in their own space. Zoning also helps reduce energy waste by conditioning only the areas that are in use.

5. Increases Energy Efficiency

Energy efficiency is one of the main reasons homeowners are switching to ductless systems. Traditional systems often lose energy through leaky ductwork up to 30% of airflow can be lost in ducts alone.

Ductless HVAC systems don’t have this problem. They also utilize inverter-driven compressors that adjust the speed of the unit in real-time based on demand, rather than cycling on and off like older systems. This constant modulation keeps your home at a consistent temperature while using less energy.

6. Quick and Easy Installation

Installing a traditional HVAC system with ductwork can take several days or even weeks, depending on your home’s layout. In contrast, ductless HVAC systems can be installed quickly sometimes in as little as one day since they require only a small hole to connect the indoor and outdoor units.

This is a benefit of ductless HVAC systems that makes them a convenient solution for new additions, detached garages, renovated attics, or any area of the home without existing ductwork.

7. Reduces Maintenance Needs

Ductless HVAC systems are known for their low-maintenance design. While regular cleaning and filter replacements are still necessary, the absence of ductwork eliminates the need for duct cleaning and maintenance. Most homeowners find that their ductless HVAC system requires fewer service calls and lasts longer than traditional systems when properly maintained.

Ready to Reap the Benefits of a Ductless HVAC System?

If you're ready to explore whether a ductless HVAC system is right for your home, the experts at Wolfgangs Cooling, Heating & Plumbing are here to help. We've been providing top-tier HVAC solutions in Tempe, AZ and surrounding areas since 1982.

From initial consultation to installation, we’re committed to helping you maximize your comfort and energy savings. Contact us today to schedule your free estimate and find out more about the many benefits of a Ductless HVAC System.

AC Preventative Maintenance: How Routine Care Prevents Emergencies

Tips for Preventing AC Emergencies Before They Start

AC preventative maintenance is one of the most effective ways to avoid unexpected breakdowns, especially during Arizona’s hottest months when your cooling system works overtime. When your air conditioner is properly maintained, it not only keeps your home cool but also helps improve energy efficiency, lower utility bills, and extend the system’s lifespan.

Extreme heat can quickly expose any weaknesses in your unit, potentially leading to a full-blown AC emergency. Fortunately, there are warning signs to watch for that can help you catch problems early. From unusual sounds and uneven temperatures to rising energy costs and odd smells, these indicators are your system’s way of asking for attention.

Here’s what you need to know to stay ahead of AC issues.

When Should You Call for AC Service?

While it’s definitely time to call a professional when your AC unit is struggling to cool your home, there are also some more subtle signs to look out for to prevent a serious AC emergency. Believe it or not, over-cooling can be a sign that your AC needs some attention.

Usually, this is a sign that your thermostat is malfunctioning and is an easy fix, but it can also cause your unit to overwork and decrease its lifespan. Poor air quality is also an indicator that your unit is struggling.

If you notice a chemical smell from the AC vents, the air doesn’t seem as fresh, or your allergies are acting up, it could be time to have your unit serviced. A chemical smell could be a sign that you have a refrigerant leak in your AC unit, which could end up costing a lot to fix if it is left to run without addressing the issue.

If you happen to hear strange sounds coming from your AC unit, it’s best to contact a professional to diagnose the issue. If you hear humming, buzzing, squealing, rattling, or clanking, it’s a sign that something is wrong. Getting things like this diagnosed right away can end up saving you a lot of money and will help prevent an AC emergency.

Tips to Prevent Air Conditioner Issues

Taking care of your HVAC system doesn’t always require professional service. There are several tasks you can, and should, handle yourself as part of an AC preventative maintenance routine:

Change Air Filters Regularly: Replace your filters every 1–3 months to keep air flowing freely and avoid buildup of dust, allergens, and debris.
Keep the Outdoor Unit Clear: Remove leaves, grass, and other debris from around the condenser. A clear area improves airflow and prevents overheating.
Clean Vents and Registers: Blocked or dirty vents restrict airflow and reduce efficiency. Make sure they’re dust-free and unobstructed.
Inspect the Thermostat: Check batteries (if applicable), and ensure settings are appropriate for the season.

Having Trouble? Call a Technician

While there’s a lot homeowners can do, professional preventative maintenance is critical for in-depth care. Scheduling a seasonal tune-up, ideally in spring before the high temperatures hit, allows a trained technician to inspect refrigerant levels, test components, clean the coils, and calibrate the thermostat.

These inspections help detect problems you might not notice on your own and reduce the likelihood of costly repairs or emergency breakdowns later. Most importantly, regular maintenance ensures your system operates at peak performance all summer long. Take action now on your AC preventative maintenance to save time and money down the line.

Air Conditioning Repair Tips to Borrow From the Pros

Air Conditioning Repair Tips to Keep Your System Running Strong

Air conditioning repair tips are essential for homeowners in Arizona, where cooling systems endure some of the harshest conditions year-round. With sweltering summers, chilly winters, and monsoon season dust storms, it's no wonder HVAC systems experience significant wear and tear. Fortunately, by applying a few pro-level tips, you can help your system run more efficiently, extend its lifespan, and avoid unexpected breakdowns.

In this guide, we'll walk you through the most effective maintenance and repair tips, straight from the HVAC professionals at Wolfgang's Cooling, Heating & Plumbing.

1. Start With Your Thermostat

One of the most common air conditioning problems isn't the unit itself, it's the thermostat. If your system isn't turning on or isn't cooling the way it should, check to make sure your thermostat is:

Set to "cool"
On the correct schedule or temperature
Running on fresh batteries (if battery-powered)

Sometimes a malfunctioning thermostat can overcool your home, causing your AC unit to work harder than it needs to. If your system runs constantly or not at all, double-check thermostat settings before calling in a pro.

2. Replace Your Air Filters Frequently

One of the simplest and most effective air conditioning repair tips is to change your air filters regularly. Dirty or clogged filters reduce airflow, strain your AC, and worsen your indoor air quality.

How often should you change filters?

Every 3 months for homes without pets
Every 2 months if you have pets
Monthly during heavy-use seasons

Clean filters keep your system running efficiently and help prevent major issues down the line.

3. Clean the Condenser Coils and Outdoor Unit

Dust and debris can build up on the outdoor condenser coils and block airflow, forcing your unit to work harder and increasing your energy bills. Each spring, follow these steps to keep your unit clean:

Turn off power to the unit
Remove the fan cover and debris inside
Gently clean the coils and fins with a garden hose (spray inside out)
Let the system dry before restoring power

Doing this simple maintenance can drastically improve performance and efficiency.

clean system

4. Check and Clear the Drain Line

Your AC unit removes moisture from the air, which drains through a condensate line. Over time, this line can clog with algae or mold, causing leaks or water damage.

To avoid issues:

Pour a cup of vinegar or hot water with mild soap down the drain line every few months
Use a wet/dry vacuum to suction clogs from the outdoor end

Keeping the line clear can prevent serious system damage.

5. Inspect for Refrigerant Leaks or Unusual Smells

If your air smells chemically or if cooling performance drops, you might have a refrigerant leak. Other signs include:

Ice on the refrigerant lines
Hissing or bubbling noises
Warm air coming from vents

Refrigerant issues must be handled by licensed HVAC technicians. If you suspect a leak, call Wolfgang's immediately to avoid damaging your compressor.

6. Listen for Strange Noises

Your AC unit should operate quietly. If you hear buzzing, grinding, squealing, or rattling, it's a red flag. Possible causes include:

Loose fan blades or motor parts
Failing capacitors
Worn bearings

Addressing strange noises early can prevent more expensive AC repairs down the road.

7. Schedule Preventative Maintenance Twice a Year

One of the best air conditioning repair tips professionals emphasize is preventative maintenance. Scheduling a tune-up in the spring and fall ensures your unit is in top shape before extreme weather hits.

During a routine visit, our technicians will:

Inspect electrical components
Test refrigerant levels
Check system pressure
Lubricate moving parts
Clean coils and drains

This proactive approach can extend your unit's life and boost energy efficiency.

8. Don’t Ignore the Ductwork

Your ducts carry cooled air throughout your home. Leaky, dirty, or uninsulated ducts can:

Cause uneven cooling
Increase energy costs
Introduce allergens into your air

Have your ductwork professionally inspected and cleaned every 3-5 years, or sooner if you notice dust buildup or uneven cooling.

9. Know When to Call the Pros

While some air conditioning repair tips are DIY-friendly, others require professional expertise. If you're dealing with persistent issues, electrical concerns, or anything that seems beyond a simple fix, call in the experts.

At Wolfgang's Cooling, Heating & Plumbing, our team has served the Phoenix area for over 40 years. We provide honest service, transparent pricing, and skilled repairs for every type of AC system.

10. Stay Consistent with Seasonal Care

Your AC needs attention in all seasons:

Spring: Clean and inspect the system before summer heat
Summer: Check filters and monitor performance
Fall: Clean coils and schedule tune-ups
Winter: Cover the outdoor unit and turn off power if unused

Staying consistent with seasonal care keeps your system efficient and reliable.

Useful DIY Dad HVAC Tips to Keep Things Running Smoothly

This Father’s Day we give thanks to dad for molding and influencing us into the resourceful problem solvers we are today.

Many useful household maintenance and repair tricks were learned under dad’s watchful eye and helpful guidance, including keeping the HVAC system running smoothly.

Now, in recognition of Father’s Day, let’s take a look at some DIY Heating and Air Conditioning tips we picked up from dad over the years, and how we can easily start implementing them in our own homes today!

Dad Always Knew When To Change the Filters

Does thinking about dad changing out your home’s HVAC filters conjure up any memories? Or, perhaps you remember riding with him to the hardware store for the 2nd time that day because he grabbed the wrong size filter replacement?

You probably have some stories, but either way, dad was staying on top of your home’s HVAC system. By replacing filters consistently, your system would provide clean air.

This helps in reducing damage to the unit... from loose particles, and reducing your monthly energy usage. Dad always knew when it was time to change the filters, and we have him to thank for those cool summers and warm winters.

Thank Your Dad For Cleaning The Outdoor Unit

Did anyone remember to venture outside to clean the outdoor unit? Probably not, but we bet dad did when the seasons changed.

A well-functioning A/C unit requires a thorough cleaning of the outdoor unit as part of its regular maintenance; this is because it collects a thick blanket of dirt and debris throughout the year, preventing the unit from properly emitting the heat it produces.

When a machine such as an AC unit can’t properly maintain its air flow, there can be a tendency for it to break down and lead to more costly repairs or replacement. So, follow dad’s example, and make sure you don’t ignore the outdoor unit and give it a thorough cleaning.

Follow These Tips to Prevent Air Leakage

Even if you diligently monitor your home’s temperature and change out the filters, it won’t matter if the air is escaping through cracks and unsealed areas of your home.

Dad knew the trick to a properly heated and cooled home was to prevent air leakage and ensure everything is properly sealed. If you need a place to start, here are some useful tips to get you going in the right direction:

Open stud cavities in older homes can lead to an outflow of air from your home; ensure these areas are properly insulated.
Caulk small gaps and foam large gaps.
Air can escape through basement and attic doors, as well as other doors leading to outdoor areas; install weatherstripping to remedy this problem.
Close your chimney flue to make sure your air isn’t flowing up and out.
Check your home’s recessed lighting for drafts or gaps.
Make sure all outlets and cable holes are properly insulated.

Proper HVAC maintenance is essential to the comfort and smooth running of a home, so be sure to thank dad for his diligence this Father’s Day. Without dad and his example of proper HVAC care, you may not have the good habits and know-how for DIY maintenance that you have today. Cheers to all the DIY Dads out there, and Happy Father’s Day!

Why Is Your AC Struggling to Cool Your House?

Common Reasons Your Air Conditioner Can’t Keep Your Home Cool

Is your AC struggling to cool your house and keep temperatures comfortable in your Tempe, AZ home? These systems are delicate and complex, and if just one component fails, the entire system can struggle. Everything must work together to keep your home cool. When your AC can't do its job, it uses more energy and risks breaking down completely.

It's essential to stay on top of the HVAC maintenance for your home to ensure there are no problems. Often, all it takes is a simple cleaning or replacement from your local air conditioner services company to do the trick. So what should homeowners be on the lookout for? Here are some of the reasons why your air conditioner is struggling.

You Might Have Ductwork Leakage

Leaky air ducts can lead to significant problems for your HVAC system. If you suspect there are any cracks or holes in the ductwork, cool air can escape before it reaches its destination, one of the common reasons for an AC struggling to cool house efficiently.

As a result, more air will need to be pumped out in order for the device to achieve the right temperature. On top of that, dust and debris from outside the ducts can enter the HVAC system, which can be dangerous to your health.

If you're worried about the general health of your ductwork, it's best to contact an air conditioner services professional to check them out.

You’ve Got a Dirty Evaporator Coil

Your air conditioner's evaporator coil is necessary to the heat exchange process, which is responsible for keeping your home cool.

It's responsible for absorbing heat from the air in your home and removing it from the building.

In order to do this, it must remain in contact with the air, which means if it gets dirty it can't do its job. This issue is why regular HVAC maintenance should always include an evaporator coil cleaning.

Your Unit Needs a New Air Filter

The primary function of an A/C air filter is to keep dust and debris out of the HVAC system. After a while, as the filter traps more unwanted particles, it can become clogged.

This buildup obstructs the air flow, which results in less air being pushed through. Homeowners are encouraged to check on the air filter every few months and swap it out for a new one when necessary.

The Unit Isn't The Right Size For Your Space

If you think a bigger air conditioner is always better for your home, think again. An oversized A/C unit, one with too much cooling capacity, can actually be a detriment to the cooling process. In fact, this is a common cause of an AC struggling to cool house properly.

The powerful compressor may end up turning on and off quickly, which won't give the system enough time to remove humidity from the air.

When installing an A/C device, always be sure to hire an air conditioning services company that will find one that's the right size based on the load.
