Common AC Problems and Causes

Many things can go wrong with an air conditioner, and there are numerous underlying causes. Most common air conditioning problems fall into three broad categories.

Not Cooling Properly

Normal wear and tear can affect cooling performance, but there are a few common issues that prevent an air conditioner from maintaining the desired temperature.
  • Dirty Filters. One of the most common problems, a dirty filter can increase energy consumption, cause frozen evaporator coils, and can contribute to unhealthy indoor Fortunately, these issues are preventable by cleaning and replacing your AC filter often.
  • Refrigerant: Your AC unit may have old, ineffective refrigerant or coolant may have dissipated or leaked out. A normal amount of refrigerant is required for proper cooling performance.
  • Sensor Problems: Your air conditioner contains numerous sensors that relay information. Over time, they can start sending false readings, causing an AC to work less reliably and efficiently.
  • Thermostat Issues: Your thermostat may not be properly reading the accurate air temperature, causing your system to “think” it is running properly when it is not.
  • Drainage Problems: An air conditioner creates condensate that must be drained away to avoid excess moisture, mold, and other problems. AC drains can become clogged with dust, dirt, and rust.
  • Dirty Coils: If the condenser coils are coated in dirt or residue, they won’t dissipate heat as effectively. The air conditioner will also work harder to cool your home; when the coils get dirty enough, it won’t ever reach the desired temperature.

Not Turning On

If your AC doesn’t respond when you turn it on or the thermostat is programmed to start it, this may be due to one of these reasons:
  • Electric Control Failure: Compressor and fan controls can wear out due to overworking or connections may become corroded.
  • Thermostat Failure: There are a variety of reasons your thermostat can fail, preventing a successful connection to your AC.
  • Faulty Motor: If the motor isn’t working, the AC won’t either. Most of the time, you’ll hear odd sounds before the unit stops working. A capacitor test can determine if the motor is the source of the problem.
  • Dirty Condensers: A condenser line can get dirty, mold or algae can grow on it, twigs and branches may build up on it, or birds may set up a nest. These can all stop your AC from working until you clear away any debris. Make sure the evaporator coils are clean as well.
  • Lack of Power: If your AC is not working it may not be getting electricity. This is easy to go unnoticed due to HVAC units having their own circuits. Make sure to check your circuit breaker.
  • Wiring Problem: An issue with your air conditioner or other electric appliances can originate with the wiring in your home. Be aware of flickering lights or listen for humming when you plug things in.

Airflow Is Limited

Limited airflow is a common problem that can happen for various reasons, some simpler to fix than others.
  • Ductwork Issues: Airflow problems may be caused by clogged, disconnected, separated, or leaky ductwork. Blocked vents and registers can cause trouble, while piece of furniture in the way can limit airflow as well.
  • Dirty Filters: While your AC is not designed to clean air, it uses filters to help remove damaging particles from getting through the system. These filters are designed to be changed frequently.
  • Obstructed Condenser: Leaves and debris that pile up around the unit can restrict airflow and cause the system to overheat. Fortunately, you don’t need a professional to clear a space around the condenser unit.
  • Faulty Blowers: The blower fans are controlled by motors. A sluggish motor can limit airflow, or a dirty fan can prevent normal operation.
  • Oversized ACs: An oversized unit will cycle on and off too frequently, so it won’t run long enough to remove humidity; the lack of airflow can make a room uncomfortable.
  • Thermostat Problem: A faulty thermostat can cause the air conditioning system to not blow enough air. Even an incorrect setting or low battery can limit airflow.

Benefits of AC Repair

Rest assured that when NexGen technicians arrive at your home, their truck will be stocked with the parts most frequently prone to failure. We carry replacement parts including blower motors, compressors, wirings, filters, refrigerant tanks and refills, trim kits, and more. Most common AC repairs can be done in one trip. Repairing your AC avoids having to spend on replacing it. It can also save on energy costs because a faulty air conditioner can waste more power while trying to achieve the same temperature. In addition to eliminating power drain, repairs help make your home or office more comfortable. Even a simple tune up can result in higher efficiency, cleaner air, and improved reliability. At NexGen, we offer unbeatable service plans to ensure your AC gets the attention it needs.

Is Air Conditioning Repair Enough?

Repairing your air conditioning system has many benefits, but it does have its limits. Our service technicians have a great deal of experience with different AC systems and can inform you when more than a simple repair is necessary. Eventually, you might want to consider central units to replace your traditional system. It all depends on various factors. So, what should you consider when deciding if an AC repair is “good enough”? Keep in mind the following factors:
  • The age of the unit. As your AC unit edges toward 20 years old, it is likely reaching the end of its lifespan.
  • Energy efficiency. Once units reach 15 years of age, they should be considered a candidate for replacement, based on energy savings alone.
  • Frequency of repairs. Frequent repairs can be frustrating, expensive, and create an uncomfortable, warm home.

Amazing Reviews From Our Loved Clients

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.

Yesterday I had NexGen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, NexGen’s price was over $3,000 cheaper than all other competitors.
Jack W.
My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend NexGen.
