Heating System Maintenance & Repair Can Prevent House Fires

Sunday, January 26th, 2014

As temperatures stay cool in the evenings and mornings here in Phoenix, many homeowners find themselves turning up the thermostat before heading to bed. Before February hits, have Cool Touch come out to your home to look at your heating system. If any heating repairs need to be performed, we’ll be sure and take care of it as this simple action may save your life and your home this winter.

The Leading Cause of House Fires

The U.S. Fire Administration reports that heating is one of the top causes of house fires nationwide, especially during the winter months. In order to keep themselves and their homes warm, many people use a variety of devices, such as fireplaces, home heating systems, and space heaters that could potentially cause a detrimental house fire, injuries, and even death.

You can easily reduce this high risk by having heating repair done on your heater before you start using it regularly and taking other protective measures. For example, if you choose to use a space heater, never leave your home with it turned on, and keep it at least three feet away from anything flammable. Space heaters cause approximately 90,000 house fires each year so be careful with these devices and use other heating methods with care.

You should also have your ducts inspected to make sure debris, lint and large quantities of dust aren’t clogged up in them. Having debris and lint clogged in your household ducts could be an easy way for a fire to start.

When looking at your heating system, make sure the flame is blue, a yellow flame may be a sign that the burner could be out of adjustment.

If your home has a fireplace have your chimney cleaned and inspected annually for creosote build-up and cracks in the mortar or chimney flues. Do not exceed the fuel capacity of your fireplace.

Protect Your Home and Your Safety

Don’t go any longer without having heating repairs done by us at Cool TouchContact us at 623-584-3762 to schedule heating maintenance and repair, serving the entire valley to protect the safety of your home and your loved ones this winter.

Your AC Unit’s Condenser Coil

Thursday, April 25th, 2013

What is a condenser coil? It’s basically one of many types of heat exchangers, and the primary purpose of a heat exchanger is to effectively transfer heat between two mediums. Your AC unit has a condenser coil within it, which has a snake like shape to it. In a heating, ventilation, and air conditioning system, water, steam, or a chemical refrigerant is used. The liquid is cooled by the chiller, then circulated through the system. The condensing coil is where the liquid mixture changes from liquid to gas. This compressed, cooled gas is then pushed through the ventilation system.

In the vapor-compression and refrigeration cycle, the condenser coil is the evaporator. This process is repeated to continually supply the building with cooled air. It is important to note that most condenser units are self-maintaining. However, over time, the unit may break down, causing a reduction in efficiency that may require the complete replacement in time.

It is very important to replace the condenser coil with the corresponding unit to avoid any damage to the air conditioning unit. Keep in mind it is best to hire a professional HVAC contractor to replace the coil on your unit. This is often required to maintain the warranty and to avoid any damage to the very expensive unit. The first sign that there may be a problem with the condenser coil is when the temperature of the cooled air is warmer than the thermostat setting.

Check the amount of refrigerant available in the system to make sure there is enough coolant. If the coolant level is OK, but the air is not cool enough, then think about replacing the condenser coil. In many areas, there are restrictions on the disposal of old condenser coils. Take the time to review the local guidelines to ensure the old unit is taken to the proper disposal center.

If you feel that it’s time to check your AC unit or the parts within it, or if home’s air is feeling warmer than what the thermostat reading states, please give us a call as we can send one of our trained professionals out to assess the potential problem. Contact us with any questions or to schedule a maintenance check.

Air Conditioning Guide: Causes of AC Short Cycling

Monday, June 25th, 2012

Air conditioning short cycling is a common problem wherein an air conditioning unit will have either short run times or short off times.  This type of quick movement back and forth between being on and off–or rather starting and stopping rapidly–can be detrimental to the overall life of an AC unit, and is also not energy efficient.

AC short cycling can have many causes, and many fixes.

  • AC Refrigerant Leak:  There could be a refrigerant leak somewhere within the AC unit.  A temporary fix might be to add refrigerant and recharge the air conditioning unit, but long-term, a Phoenix air conditioning specialist will need to be contacted in order to find and fix the leak properly, ensuring excess money is not paid to continually add an unnecessary amount of refrigerant.
  • AC Coil Icing: This means that the evaporator coil or cooling coil has become encrusted with ice or frost and is causing the unit to malfunction by turning on and off in short bursts.  Turning off the unit completely and letting the ice melt, then checking and replacing dirty filters can oftentimes fix this problem.
  • AC is Oversized:  The amount of power needed (or the BTUs needed) to cool a space is directly proportional to the size of the space or room which is being cooled.
    • If AC short cycling has been a constant problem since day one of an AC system installation, it is entirely possible that the A/C unit is too large for the space which it is cooling.  This could mean contacting an HVAC technician to have the unit analyzed and a new, smaller unit put in.
    • If A/C short cycling is a relatively new problem, some possible causes could be: closing or opening doors which previously were not closed or opened frequently, or the addition of partitions within rooms which effectively makes the room size smaller.  This could mean simply adjusting the thermostat, or the blower fan to a lower speed to compensate for the change, or opening interior doors to increase the size of the space which is being cooled by the AC unit.
  • AC Control Board Problem:  While less likely, the problem could be in a control board or control switch which has been damaged, thus causing erratic and rapid starting and stopping cycles.  In this case an air conditioning technician would need to be contacted in order to replace the broken control switch.
  • AC Compressor Damage or Start-Up Issues:  Some AC systems have hard-starting compressors which take time to re-pressurize properly after shutting down.  If the AC system is being turned on or off manually on a frequent basis, the compressor might have a hard time restarting because the high pressure which had built up on the previous on-cycle had not had a chance to come down to normal levels again.  An easy way to diagnose this problem is if after leaving the AC unit shut off for thirty minutes, the unit works properly after being turned on again.  To help this compressor issue, an HVAC service technician can add a starter capacitor to the AC unit.

These and other AC short cycling causes can be checked, diagnosed, and fixed quite easily by an experienced HVAC professional, so call Cool Touch Air Conditioning, Heating, Plumbing & Electrical if you are having any problems with your Phoenix air conditioning system!

Air Conditioning FAQs: How Do I Determine the Cooling Capacity of My Central AC or Heat Pump System?

Monday, June 18th, 2012

For any type of air conditioning system in Phoenix, the cooling capacity is measured in BTU’s. This is important to know if the system doesn’t seem to be adequately cooking your home, and there are many different ways to check the cooling capacity of your AC system.

1. Air Conditioning System’s Age and Serial Numbers

An air conditioner’s age will usually give you a general idea for its cooling capacity, and if you aren’t sure, you can always check the serial number. Because serial number formats vary by the year the equipment was made, you can check to see how old an air conditioner is from looking at the serial number.

The first four digits of every serial number is the week and year the unit was manufactured.  For example, the serial# 1188E53294 on a compressor unit tells us that it was made between 1980 and 1990, and to be more exact, week 11 in 1988.

2. Air Conditioner’s Model Number

You should also look at the model number for your specific model because some manufacturers also vary how they assign each number in the serial number; however, they usually stand for tonnage or MBTUH. You can always call us if you aren’t sure how to read the serial number or model number.

3. AC Equipment’s RLA Numbers

RLA stands for “Rated Load Amps,” which means that it’s the manufacturer’s rate of the cooling capacity (also known as the draw) or load while it’s operating (minus the draw when you start the system). Most air conditioning compressor or condenser units will draw 5 to 6 RLA per ton of cooling capacity. You can check the data tag on the compressor for the RLA rating; however, this will need to be translated into BTUH for the total cooling capacity.

Feel free to call one of the Phoenix air conditioning experts at Cool Touch if you have any questions how to calculate your AC system’s cooling capacity.

Air Conditioning Tips: How to Avoid Mold Problems and Rust Issues in HVAC Blower Compartments & Ductwork

Monday, June 11th, 2012

Mold and rust are not just unsightly, they can be corrosive to the structure of your home and possibly hazardous to your health. One of the last places you want those two things to take root is within your Glendale AC system, where they could be hidden from view for months.

So, follow this brief guide to prevent mold and rust problems from developing.

1.     Use high quality filters

A poor air filter lets through all kinds of contaminants, including organic matter. If mold spores get into your blower compartment or ductwork, it can bloom undetected for quite some time. Use a high quality filter that keeps out mold spores and other biological contaminants.

2.     Keep filters clean

The best filter in the world is no good if it is too dirty to function, so keep yours clean. Replace and/or clean them regularly in accordance with manufacturer recommendations.

3.     Pay attention to and fix leaks right away

The big problem with both rust and mold is moisture. Excess moisture that gets inside your AC system can wreak havoc. The water can corrode the metallic parts inside, giving rust free reign of your blower compartment or ductwork. Even worse, if water is added to some of those mold spores from the poor filter (see #1), the environment is perfect for mold to grow.

So, be aware of things like wall and ceiling leaks, wet insulation or moisture accumulating around the blower compartment. These are not uncommon problems with AC systems because of coil icing, poor condensate drainage and other issues, and they can easily turn into mold and rust problems if left unchecked.

4.     Be aware of humidity

If your home is too humid, even while the AC is running, get it looked at. This could be a symptom of an extra moisture source somewhere.

5.     Have AC problems fixed professionally

Finally, when you need to perform air conditioning repairs, have them professionally repaired. Many AC issues are related or the symptom of a larger problem, so fixing one thing may not solve the real issue. De-icing the condenser coil, for example, but not fixing the associated leak, could mean that the problem will come back, and in the mean time there’s plenty of water to cause rust and mold problems.

How to Fix Wrong Sized Air Filters on Heating or Air Conditioning Systems

Monday, June 4th, 2012

If you have had an HVAC technician repair or maintain your air conditioning system for you lately in Goodyear, you may notice that whoever did the job put on the wrong size filter. This is not uncommon and is usually the result of an effort to save either time or money. However, in the long run it actually costs both. Here is how you can fix the problem of a wrong size filter.

The WRONG Way

If you have a filter that is too big for your system, it may seem like an easy enough fix– just fold it over or trim it down, right? Not so fast.

Folding the filter over makes for an imperfect seal. Air will leak through and around the bend, bypassing the filter entirely. This causes dirt and debris to build up on the fan, slows down air flow, degrades performance, decreases air quality and overall makes a big mess that you will have to pay to fix or clean up later.

Bending or cutting the filter also decreases its structural integrity. The whole filter can collapse while installed, creating not just a performance issue and a potentially costly repair, but also possibly creating unsafe conditions.

Furthermore, don’t give into the temptation to run your HVAC system without a filter for the time being. The debris will quickly build up in your AC system, as well as being blown into your home. Heating and cooling systems should always be operated with the proper filter installed.

The RIGHT Way

So, what do you do when you have an air filter that is the wrong size? The only solution is to find the right size. If you are having trouble finding the right air filter for your system, try these tips:

  • Refer to your owner’s manual for the filter model number.
  • Bring the make and model information of your heating/cooling system to the store and ask someone there for help.
  • Any time you are having services like air conditioner replacements performed on your AC system it is best to have a professional help out. (You should have a professional inspection once a year, anyway.)
  • For HVAC systems that are large or have special dimensions, special order custom filters to fit.
  • Above all, never operate your HVAC system without a clean, correctly sized filter properly installed.

When you are ready to install your new air conditioning system please contact Cool Touch Air Conditioning & Heating Specialists.

Indoor and Outdoor AC Components Should Be Replaced at the Same Time in Peoria

Tuesday, May 29th, 2012

Does one of your ductless air conditioner components need replacing? If so, you are probably tempted to just replace whichever unit is failing in order to fix the problem quickly and cheaply. This is not always the best way to go, however. Here are six reasons why you should replace both the indoor and outdoor units at the same time.

#1: Cost

Although replacing just the failing component – whether indoor or outdoor – will be less expensive up front, that choice often proves more costly overall. You will see just what that means in the rest of these reasons.

#2: Advances in design

Heating and cooling technology is always advancing, so since you purchased your AC system, the products on the market have gotten quieter, more efficient and better overall. By replacing just the failing indoor component, you won’t reap all the benefits of this new technology, as the older outdoor component will still lag behind the times.

#3: Higher efficiency

When both units are replaced at the same time, and with models that have the same technology, they work together more efficiently. That means more savings on your bills and a more comfortable home.

#4: Matched system

Split AC systems are designed such that the indoor units are engineered to work best with a matching outdoor unit. When the system is matched, you get optimum performance and efficiency. By replacing just one component, you lose the benefits of that matching, meaning degraded efficiency and performance.

#5: Warranty considerations

A new system means new warranty coverage. Replacing both units at once means a whole new warranty that covers your whole cooling system, so you won’t have to worry about paying for any more replacements jobs for a long time.

#6: Wear and tear

Finally, think about the wear and tear your air conditioning system has undergone since it was installed. Maybe only your outdoor unit needs to be replaced now, but since your indoor unit has tolerated the same number of hours of use, it may be on its way out sooner than later. It’s like when you buy new tires for your car– you don’t buy one or two, you buy a whole set of four so that the whole system starts fresh. That way you only do it once, and not again in six months or a year.

For all these reasons, replacing both components of a split system is often the best and least expensive route to choose when facing a replacement.  For help with air conditioning replacements please call Cool Touch Air Conditioning & Heating Specialists.

Outdoor Air Conditioning Components for Tempe Homes

Monday, May 21st, 2012

As long as all the parts are working well, air conditioning in Tempe is a modern convenience we can easily take for granted and overlook. Cool air makes our lives simply better, but is a complicated process based on an old theory and modern technology.

No matter the size, in every unit, the basic purpose is one of extracting heat from the conditioned space and moving it to the outside, leaving cool air in its place. This process easily divides into indoor and outdoor components.

Air Conditioning 101

Utilizing the basic principal of thermal energy that heat gravitates toward cooler temperatures, compounds known as refrigerants travel through a closed looped system, repeatedly transforming between liquid and gas forms. Chosen for their ability to rapidly change at low temperatures, they alternately absorb and release heat along the way.

Having expanded to a vacuous state with plenty of room between molecules to absorb heat, the refrigerant is compressed tightly, condenses back into liquid form and releases the heat to the outdoors.

In the Box Outside

Placed on a small slab on the ground alongside many homes or on the roof of large buildings, air conditioning units contain the compressor and condensing coils that enable the main (and noisiest) function of the process.

The refrigerant is contained within a closed loop, entering the compressor as an expanded gas full of heat.  Under pressure, that heat is released when the molecules are squeezed so tightly together the refrigerant returns to its liquid state.

The passing into the condensing coils, a series of delicate fins, the released heat is allowed to dissipate through the fins into the air where a small fan blows it away.  Water is also a by-product of the condensation and drains into a pan and eventually into the ground.

The condensing coil ends at the exchange valve where it is held to create just the right pressure for the evaporating coil indoors to operate at its maximum efficiency.

Refreshing Maintenance

If air conditioning maintenance is performed regularly, the system requires little attention and over sight beyond scheduled appointments with a company like Cool Touch Air Conditioning & Heating Specialists.  Even in the most brutal of climates, relaxed and comfortable in our spaces, we are able to do our stuff and sleep well at night.

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!
