Air Conditioning Repair & Installation

Q: What do I do if my A/C is blowing hot air?

A: While this question has many possible answers, we can still go over some basics. First, make sure the breaker is not tripped. If the breaker is okay, see if the fan is spinning at the top of your outside unit. If it's not, the problem could be a bad fan motor, capacitor or both. If the fan is spinning, reach down and hold the larger of the two copper lines. They are usually wrapped in black insulation. See if the lines are cold. If not, the unit could be low on Freon, have a bad compressor, or both. The best thing to do in this case is call a certified A/C repair professional.

To see one thing we check during our spring tune-ups, watch our video about an air conditioning capacitor check:

Q: I changed out my thermostat and now my A/C will not come on. Why not?

A: It's always a good rule of thumb to double check the wiring you performed to ensure all connections are tight and you followed the instructions correctly. If during installation the main power was not turned off, you may have blown a control fuse. If you are able to correct the wiring and feel comfortable opening up the unit or air handler panels, then changing out the fuse is a simple solution. Just ensure all power to the unit is off at the breaker box. Find the control fuse, which is usually mounted on the control board inside the unit or air handler panel. Do not oversize the fuse! If it calls for a 3amp fuse, use a 3amp fuse only.

After replacing the fuse, close all the panels and turn the power back on. You should be good to go. If the control fuse blows again, it's possible you wired the thermostat incorrectly or have a short circuit in the control wiring. It's best at this point to schedule an A/C repair service before more damage is done to the air conditioning system.

Q: I have water dripping from an outside pipe. Is this related to my air conditioning and what does it mean?

A: This is actually a very common problem, with the root at the A/C condensate drain lines the come from the evaporator coil. These are located in the unit that is inside your home, usually in a hall closet or the attic.

When you use your air conditioning, the A/C evaporator coil creates condensation. This condensation is supposed to drain through the normal plumbing in your home. Water draining from a pipe outside your home is actually the secondary drain line indicating to you that there is a problem with the primary drain line. However, this is usually a simple fix of just clearing the primary drain lines. It would be good to install a drain line flush kit. Just don't ignore the problem. Ignoring it can cause serious damage to your home, such as flooding to your ceiling or flooring. If unable to clear and stop yourself, call a professional.

Q: My A/C is not cooling and there is ice on my outside unit. What does this mean?

A: While there is more than one possibility here, there are two main reasons an air conditioning system will freeze:

1) Low Freon. However, don't just assume the Freon is low. Freon should be checked annually during your spring tune-up that should be performed by a certified professional.

2) A restriction in airflow. A dirty air filter, dirty evaporator coil, or even a blocked return duct can cause restriction. The first step is to defrost your entire system. This could take three to eight hours, depending. If the filter is dirty, then replace it with a clean one of good quality. Low quality air filters (which you can see through) may cause you to have to clean your evaporate coil as well.

Q: How do I know if I need to replace my air conditioning system?

A: There are many factors to consider; but if your system is old, inefficient or in constant need of repair, it's time to replace. Today's systems are as much as 60% more efficient than those manufactured even just 10 years ago. The cost savings on your utility bill should provide a pretty attractive return on your investment. Even if you plan on financing your new A/C system purchase, the monthly savings on your utility bill should be considered when determining the actual cost of replacing your current system.

Some other things to consider, such as how air conditioners can save money by being more energy efficient when having a certain Seasonal Energy Efficiency Ratio (SEER), can be found on this infographic:

Heating Repair & Installation

Q: What do I do if my heater is blowing cold air?

A: There are many things that could be wrong, but there are some simple things you can try yourself to get the warm air you need blowing. First, try rebooting your system. Because modern furnaces are computer-controlled, there could be a glitch preventing fuel from being delivered. Try turning the furnace switch to "Off," then wait 30 seconds for the system to reboot before turning back on. If this doesn't solve the problem it's time to look more deeply. The second thing you should try is a series of checks, based around the four major components that keep a furnace working properly. These components are the fuel system, the burners, the fan and the duct work. For the rest of this answer, please see My Furnace is Blowing Cold Air! Now What?

Q: I know I need a new furnace but I'm not sure what to expect with a brand new system that requires hooking up to a gas line. What assurances can you give me that you will install safely?

A: Rest assured. We're not only trained and certified professionals, but we also have a safety process that starts before an A#1 Air technician ever arrives at your home. Watch this video to see exactly what we mean:

Q: What is two-stage heating?

A: With two-stage heating, the furnace has two levels of heat output. One is a high output for extremely cold days and the other is a low output for milder cold days. Because the low output is sufficient for heating needs the majority of the time, a two-stage heating unit runs for longer periods of time, which provides more even heat distribution. The longer, low output operation has several advantages such as consistent comfort, improved energy efficiency, improved indoor air quality, and a quieter operation.

Q: How long can I expect my furnace to last?

A: Life expectancies for furnaces vary, depending on many factors, but an average expectancy is 10 to 20 years. In some cases it's worth it to replace an old system before that time in order to take advantage of a more energy efficient unit that could save you money on your monthly bill. The key to getting the most efficient and longest lasting use of your furnace is initial proper installation and recommended maintenance.

General Air Conditioning and Heating FAQs:

Q: My utility bill keeps going up and the temperature is not the same in each room. Why?

A: There could be more than one factor going on, but in many cases there is not enough return air or the ductwork is inefficient. In these cases, the system is running longer and working harder than it needs to as it tries to reach the temperature set on the thermostat. Watch our video that explains what return air is and why it's so important:

Q: How do I determine what size system I need?

A: This answer is not black and white. It takes a trained, certified technician who not only knows HVAC industry energy standards and government energy standards, but who also knows how to properly perform a heat load calculation, which assesses British Thermal Units (BTU), that is specific to our climate. A major factor to weigh in for our Dallas, Fort Worth area is the hotter temperatures and higher humidity. The new government standards do not take into consideration our Texas climate. But we do. The government standards are based on 95 degrees, with 70% humidity. But here in the North Texas area, we need to consider heat load calculations at 105 degrees, with higher humidity.

You really do need a certified technician to determine what size unit is best for your home or business. These assessments are necessary to properly balance the system with the area it will heat or cool. Other considerations include changes made to the home or business since the last system was installed such as new doors, windows and insulation, how many people occupy the area, and more.

Q: How often do I need to change or clean my filter?

A: Inspect your filter once a month. If a simple clean will do, you can reuse. But if it's really dirty, or damaged in any way, you need to replace with a new one.

Q: Doesn't a heat pump work for heat only?

A: No. A heat pump works year-round for both heating and cooling to keep you comfortable. In cold months, the heat pump collects heat from outside air and transfers it to the inside air to keep you warm. During warm months, it extracts heat from inside the home and transfers it to the outdoor air to keep you cool.

Q: Should I be concerned about indoor air quality?

A: Yes. According to the Environmental Protection Agency, your exposure to air pollutants can be up to 100 times higher indoors that outdoors. For more information, see Indoor Air Quality.

Q: What brands do you carry and service?

A: We carry and service all brands. One of our Comfort Care Specialists can help you.

A: Yes! To get the current year's information, please see A#1 Air's Tax Credits, Rebates & Other Specials.

Q: What is a heat load calculation?

A: A heat load calculation is a formula used by an HVAC professional to assess the thermal quantity needed. This determines the correct size of a furnace or air conditioning unit for a specific space. Many factors are considered, such as individual room sizes, insulation, weather stripping, number of window and doors, average number of occupants, exterior-facing walls, glass store fronts, typical weather climate, solar radiation (direct sunlight received through windows and doors and for how long each day), appliances, desired temperature ranges and much more. These factors collectively calculate the proper BTU (see below) output.

Q: What is a British Thermal Unit (BTU)?

A: A British Thermal Unit is a traditional unit of energy needed to heat or cool. It is commonly used as a measure of power and is the standard unit of classification in the heating and air conditioning industry. While many BTU definitions exist, a BTU can be approximated as the heat produced by burning a single wooden kitchen match.
