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.
