Air Conditioner Tip: Signs of an AC Fan Motor Problem

Monday, September 17th, 2012

Should your air conditioner suffer from a problem with its fan motor, there are a number of signs you can look for that will signal it is time to call an air conditioning professional to inspect and repair the problem. Here are three such problems and what you should do about them.

Fan Shuts Off

If your fan turns off before the cycle is fully completed, there may be an electrical issue that keeps it from continuing. Bad wiring, a short out in the motor itself or an issue with the circuit breaker or fuse may cause this problem, and it should be inspected by a professional right away. In many cases a single part can be replaced to repair the problem.

No Air Flow

If your fan is on but is not actually circulating air, either because it is not only high enough or because of another issue, it can be due to a couple possible problems. It may be worn to the point that the fan itself needs to be replaced or it may be that the motor is dying – a natural problem late in its life cycle. Other possible issues include loose screws or wiring or an actual obstruction in the fan assembly.


If the fan motor is making a lot of noise, most likely it is because of a loose part clanging against the body of the fan motor when it is running. If this is the case, you can look for such a loose part, though because this repair often requires opening the cover to the fan motor, it is recommended that you call a professional for any such inspections.

Whatever your issues, it is important that you call a Phoenix air conditioning professional to repair the problem. Fan motor problems are often electrical and it can be dangerous to work on them without specific expertise working on electrical systems.

For air conditioning repair in the Phoenix area, you can count on Cool Touch for quality service.

Air Conditioning Guide: Common Reasons Your AC Freezes

Monday, September 10th, 2012

Air conditioning has changed our lifestyle a lot in Phoenix. It lets us stay comfortable indoors, while doing anything from working to sleeping. However, there is nothing worse than your Phoenix air conditioner freezing up on a hot day. Many common problems can cause your air conditioner to freeze.

  • Lack of Sufficient Air Flow

If the air filters in your air conditioner get clogged, collapsed or obstructed or you have undersized air ducts, the air flow from the air conditioner will be restricted, causing the system to freeze. Dirt build-up on the evaporator coil and humidity in the air collected on the coil causing ice build-ups can also restrict air flow.

  • Problems in the Refrigerant

Your air conditioner may end up freezing, if the amount of refrigerant in it is not balanced. If there is very little refrigerant in the coil, it will be extremely difficult for it to absorb heat. This can cause the air conditioner to freeze.

Air conditioners use refrigerant to cool the air that circulates through their system. If the refrigerant level becomes very low, the air conditioner will need to work overtime to circulate cool air. This can cause your AC to freeze. If you suspect that your AC has a low level of refrigerant, it is advisable to get the help of a licensed Phoenix AC professional immediately. Refilling the refrigerant can help you fix this problem. However, it is not advisable to attempt to refill your system on your own, as should be handled only by licensed technicians.

  • Outside Temperature

If there is extreme change in the outdoor temperature within a short period of time, there’s a good chance your air conditioner will freeze up. This problem can be prevented, however, by turning off your AC when the outdoor temperature drops significantly.

A frozen air conditioner causes cooling problems. Regardless of the reason that your Phoenix air conditioning system developed this problem, it is worth getting the help of a certified professional to fix it. This not only helps you restore a comfortable environment in your home, but it will also save you a lot of money in energy bills.  For any AC repair in the Phoenix area, give Cool Touch a call!

Air Conditioning Guide: Programmable Thermostats and Your AC

Tuesday, September 4th, 2012

Programmable thermostats offer many advantages over traditional mechanical thermostats that measure the temperature in your home with expanding and contracting metal coils. While the latter is perfectly accurate most of the time, it requires that your entire Phoenix air conditioning system turn on at the same time and remain on, even if you are not home. A digital thermostat, however, can be programmed to turn on under certain circumstances and be put on a timer for when you are not home.

What this means for your cooling system is that you can set you thermostat to turn on and off for different parts of your home based on when you will be there and when the temperature will get high enough to warrant it.

For example, if you are away from the house every day between 7:30am and 6pm, you can set your programmable thermostat to 85 degrees during those hours when you are away. This will save you money on your cooling bill while ensuring the home doesn’t get so hot that it is dangerous or uncomfortable for pets or plants. The programmable thermostat can then be set to turn on 30 minutes or so before you return home so that it is cool in the house by the time you arrive at 6pm.

This system works in a number of ways. Some thermostats are available with 7 day programming while others offer 5+1+1 programming, allowing you to set different temperatures for weekdays and each day of the weekend. Certain models will even integrate with whole-house control systems so you can turn the thermostat on and off with a computer remotely – setting a number of carefully controlled variables for when it will be on and off.

Whatever you decide to do with your thermostat, know that having a programmable system offers many benefits to you as a homeowner, not only in terms of comfort but also in how much you spend each summer on your cooling bill. For more tip on how to use your Phoenix air conditioning system effectively, give Cool Touch a call!

AC Guide: Air Conditioning Performance Issues

Monday, August 27th, 2012

When an air conditioning system begins to have performance issues, it can be due to a number of common causes.  Whether your AC has stopped cooling, simply will not turn on, or has water pooling around it, the Anthem AC professionals at Cool Touch can help you understand your air conditioning performance issues while also providing quick solutions.

AC Not Cooling

An air conditioner that isn’t cooling can indicate a couple of key problems.  If there is not enough refrigerant,  the AC will stop cooling.  If there is debris causing reduced airflow anywhere in the AC, including clogged air filters, dirty condenser coils, or dirty evaporator coils, it can cause your AC to work much less effectively.

AC Doesn’t Turn On

It could be a blown fuse or tripped circuit breaker that shut power off to the AC.  It could also be a drainage problem – if the drain pan got too full, it triggers an automatic shut off so that a water leak does not occur.  It could also be a broken thermostat which needs to be replaced.

Water Pooling Around Air Conditioner

When water pools around the actual air conditioner unit, there could be a drainage clog.  It could also be a condensate drain tube leak, which would mean a tube replacement.  There could also be ice buildup on coils that has defrosted and melted, causing water to pool around the AC.  If this is the case, the cause of the ice buildup should be determined to prevent the problem from reoccurring.

No matter what your particular air conditioning performance issue happens to be, Cool Touch has a qualified team of Anthem AC technicians that can help. Call us today!

AC Tip: Central Air Conditioning Components

Monday, July 30th, 2012

In understanding how air conditioners work, as well as what internal systems affect each other, it is important to know about some of the main central air conditioning components.  It can also help you decide when it may be time for a repair or maintenance tune-up. Cool Touch Air Conditioning, Heating, Plumbing & Electrical provides air conditioning repair and maintenance to Scottsdale, AZ and the surrounding areas in Sun City, Arizona. Call us if you have questions about your AC system.

Air Conditioning Parts and Components

Some of the most essential air conditioning parts include the compressor, the condenser coil, and the evaporator coils.  There are also air filters, coil fins, contactor relays, time delay, and the compressor power pack.

The compressor is one of the hardest working central AC components.  It pressurizes the refrigerant causing it to turn into a vapor, and then pushes it toward the condenser. The condenser coil soaks up heat, where it becomes superheated, and the vapor is pushed into the condenser coil where the vapor hits outside air and all that heat is removed.

The evaporator coils takes over after that previous vapor turns back into a liquid.  The liquid hits the evaporator coils and mixes with hot air.  The refrigerant in liquid form soaks up moisture and heat and then condenses it, draining it from the system.  This leaves the air cooled.

Air filters keep unwanted particles, dust and debris from entering into the air conditioner and causing clogs in the system. Coil fins are a part of the evaporator and condenser coils and are essential to those AC parts properly functioning. Contractor relays control the fan and compressor, turning it on an off as necessary. Time delays will protect the contactor from any power surges which might occur, as well as creating a space between when the contractor turns on and off in order to prevent short cycling.

All of these are essential central air conditioning components that work together to keep your AC system running efficiently.  Let the Scottsdale, AZ air conditioning technicians at Cool Touch Air Conditioning, Heating, Plumbing & Electrical help with all your air conditioner repair and maintenance needs this summer.

AC Q/A: What Are Common AC Fan Problems?

Monday, July 23rd, 2012

It is common for central air conditioners to make a small amount of noise while running, such as a small humming sound when the fan blows.  However, excessive noise is a sign that something has gone wrong: possibly a blower problem or a fan problem.  When think you have a fan problem, contact the Scottsdale air conditioning professionals at Cool Touch and have your AC system inspected, fixed and running efficiently.

What Is An AC Blower?

The air conditioner blower is actually the fan inside the AC unit which sends cool air through the cooling coil and into an indoor space.  It keeps the air moving.  When it doesn’t work the air conditioning system tends to not work as well.

When an AC Blower Will Not Start

When you turn on the air conditioner and it doesn’t start, there tends to be no sound coming from the fan motor as well as no cold air moving into the building.  This could mean that the air conditioner is overheating, or even that a fan belt has stopped working.  Our air conditioning technicians can identify and resolve this type of AC blower problem.

When There is Ice Buildup on the Air Conditioner

If your air conditioner has begun to form its own colony of icicles, which can also cause it to not work as efficiently as it once did, this tends to be a sign of a fan problem.  Commonly this could mean that the air conditioner fan has become clogged with dust and dirt and is no longer efficiently allowing the cooled air out of the AC unit.  Or it could mean that a broken fan is no longer properly circulating air.  Either way, our experienced Scottsdale air conditioning technicians can diagnose and solve these air conditioner fan blower problems.

Contact Cool Touch and receive excellent air conditioning system services from our team of highly trained Scottsdale AC technicians.

Central Air Conditioning Installation in Phoenix: Factors to Consider

Monday, July 16th, 2012

Opting for central air conditioning is a big step, and one that many Phoenix homeowners take happily as they look forward to the comfort that the cool air will bring. But there is the little matter of installation to consider, and some less known factors that are tied up in that.

 1.       What you can afford

Before making any major purchase, including central air conditioning, first create a budget for yourself. Determine how much you can afford and let that drive and inform your decision making, rather than falling in love with a particular model or set of features regardless of price.

 2.       Getting the right size

If you ask a Phoenix AC professional, he will tell you that getting air conditioning equipment that has been properly sized is essential. To get an AC system with the right capacity, you must consider not just the size of the rooms to be cooled, but also the local climate, the function of each room (bathrooms and kitchens require extra cooling), the usual number of occupants of a given room, the quality of insulation in the house and other factors. The best way to do a thorough job with this step is to have a professional do a load calculation for our whole home.

 3.       Working with what you have

Many homes have ductwork already in place, which is great for adding central air. If your home does not have ductwork installed already, then consider a ductless mini-split system as an alternative to the expensive and time-consuming task of installing new ductwork.

 4.       Where to place the outdoor unit

The outdoor condenser/compressor unit should be carefully and strategically placed for optimal operation and functionality. It should be on a concrete or vinyl pad, with space between it and the house and with no vegetation encroaching upon it. Consider all these things when choosing a place for it to rest. A professional installer will know how to place it properly.

You can see that purchasing and installing central air conditioning is not a particularly simple process, but that’s only because there are these important things to consider. With careful consultation with a Phoenix air conditioning professional like Cool Touch Air Conditioning, Heating, Plumbing & Electrical to guide you, it does not have to be a stressful or frustrating task.

Electrical Question: Should I Upgrade My Fuse Box?

Monday, July 9th, 2012

If you’re wondering whether to upgrade your Scottsdale home’s old fuse box, the answer is probably yes. All electricity entering your home passes through this box. The electricity is divvied up to all of your appliances and electronics from this point. That’s a lot going on in one little space, and a lot of potential for something to go wrong.

If you have an older home and the electrical system has not been updated in years, it is possible that your existing electrical system, while functional, is not up to code. Upgrading your old fuse box is an important improvement in the safety of your home’s electrical system. The most important information in deciding whether or not to upgrade your home’s fuse box is to make sure that you understand how it works.

The fuse box is the panel in your home where circuits are completed by little strips of metal. The small plastic capsules containing the strip of metal constitute the fuse. This fuse connects the circuits in your Scottsdale electrical system and allows electricity to run through them. In the event of a surge in which unsafe levels of electricity are flowing through your system the fuse will blow, and the circuit is broken. This ensures that your wiring is not overloaded with potentially dangerous levels of electricity.

A sure sign that your fuse box is not operating properly is an increase in blown fuses. If your fuses seem to go more often than they used to, call a qualified electrician to inspect your box. It may require an upgrade. Other signs of an unsafe fuse box include rust, scorch marks, corrosion of wires or components or simple old age. If you have any reason at all to question the integrity of the fuse box in your home, do not hesitate to call for a professional evaluation. This is a matter of personal safety.

If it is decided that your fuse box needs an upgrade, consider the advantages and disadvantages of both fuse boxes and modern circuit breakers. Fuses tend to react to overloads very quickly, which can mean better protection to sensitive electronics. However, this can be inconvenient when in a circuit prone to frequent surges that blow the fuse. Circuit breakers make it easy to locate which switch has tripped, and they reset with the simple flip of a switch. However, they do not register surges as quickly as fuses.

The best way to decide what is right for your home’s electrical system is with the help of a Scottsdale  electrical professional. Call Cool Touch today with any questions you have. We’ll help make the decisions that are right for your home’s electrical system.

AC Question: How Do Ductless Mini Split Air Conditioners Work?

Monday, July 2nd, 2012

Ductless mini split systems, or just ductless mini splits, are actually very simple devices. Despite their small size and sleek appearance, they are less complicated than many alternative systems. The elimination of centralized ductwork is to thank for this simplicity, as well as making ductless mini splits a great option for Phoenix residences without room for bulky duct systems.

Like more traditional centralized cooling systems, the noisy components of a ductless mini split system are kept outside. The wall units themselves emit little more than a hum as they disperse the conditioned air throughout your home. These wall units each contain a refrigerant coil and blower internally. Because both the refrigerant coil and blowers are found within the wall unit it is simple to control the temperature of different rooms separately. This zoning process adds to the system’s overall efficiency, allowing you to cool only those rooms in use through the use of multiple wall units.

It is the connection between these indoor and outdoor components that make the installation of ductless mini split systems so convenient. Installing a traditional forced air central cooling system can be a big project. When installing a ductless system all that is needed is a three inch hole drilled in your wall. Small copper pipes connect the components of the system, piping refrigerant between the compressor and the indoor wall units.

Like any HVAC unit, it is important to remember that ductless mini splits do have some possible drawbacks. While the lack of ductwork does make for easier installation and eliminate the need for a lot of space, it also means that a ductless mini split system does not provide ventilation. This is not a problem in most residences where operable windows allow for easy ventilation, but some commercial spaces may require an AC unit capable of ventilation.

If you are considering a ductless mini split system with heating in mind, know your climate. Some models come equipped to heat with an electric source, but there are also heat pump type ductless systems that work much like an air-source heat pump. These can be supplemented electrically, but if you live in an area where extremely cold weather is common you may want to consider a different HVAC system.

As is the case with any investment, you want to be sure that you are getting a product that will work for your specific needs. Ductless mini splits are not right for everyone. Call the professionals at Cool Touch Air Conditioning, Heating, Plumbing and Electrical to help you decide what system you’ll benefit most from.

Spring Cleaning and Your HVAC System in Buckeye

Monday, May 14th, 2012

If you are working on cleaning your home for spring, don’t forget your heating and air conditioning system in Buckeye. If you are turning your furnace off, you should change the air filter so it is ready to go next heating season. It is also important to check your air conditioner’s filter, which needs to be clean to ensure efficient operation. A dirty AC filter can reduce air flow, which can not only waste energy but possibly cause ice to build up on your coils.

While you are checking over your AC equipment, it’s a good idea to schedule an annual air conditioning maintenance visit with your HVAC contractor. One of the many things they will do is clean your AC, including the evaporator and condenser coils, which will help your unit maintain its energy efficiency. Since you are cleaning the rest of your home anyway, it’s a good idea to get your air conditioner in peak shape at the same time. If you don’t know how to change your AC’s air filter, ask your maintenance technician to show you. You should also determine how often you should change your air filter, which can depend on the amount of dust in your home, the number of pets you have, and the type of air filter you use.

Other important spring cleaning tasks include changing the filter in your vacuum, which can help maintain indoor air quality, and changing your water filter. Whether you have a whole house water filter or a Brita pitcher, the filters need to be replaced on a regular basis to keep them working effectively. If you have an air cleaning system, it’s probably a good idea to replace those filters as well, and check to make sure you don’t need UV germicidal light bulb replacement. While each of these steps seems simple, it they can add up to a healthier, more efficient house.

To schedule an HVAC maintenance visit, call Cool Touch Air Conditioning and Heating Specialists today!
