Common Air Conditioner Problems

05.28.19

The weather is heating up! Now is not the time to have an air conditioning issue. Here are some common AC problems and what to do about them.

Your Outdoor Unit Won’t Turn On

When an outdoor unit isn’t responding, it’s usually because the circuit breaker has been tripped. Locate your circuit breaker panel and reset the switch.

Still not working? Check your thermostat. If your thermostat isn’t communicating with the rest of your central air system, it’s time to give Stuart Pro a call.

The Air Conditioner Isn’t Cooling Evenly

Are some rooms in your home freezing while others feel like a sauna? There could be multiple issues affecting the temperature in each room. A duct could be blocked, or it could be something as simple as how much sun is coming through windows. If you have tried closing your curtains and blinds with no change, then chances are something else is impacting your HVAC system. We are happy to assess your home environment and customize the air conditioning to each room so that you are pleased with the temperature.

The AC Doesn’t Cool At All

When the air coming through your vents isn’t cold, the problem is either with the control board or the refrigerant. You should call Stuart Pro in both cases. Please be careful around refrigerants, which can be very hazardous to your safety and health.

The Condenser Unit Turns On and Off Constantly

The outside condenser unit contains safety controls that automatically shut down the system when the pressure drops below a certain level. When pressure rises again, the system turns on. If your condenser continues to turn on and off, Stuart Pro will need to assess the safety controls to ensure optimal performance.

The Condenser Unit Won’t Turn On

If your condenser unit won’t turn on, it’s time to recheck your circuit breaker. If after resetting the switch it remains off, there is likely a more significant problem related to your wiring or thermostat.

Common Causes of AC Problems

Wiring: When wires erode, break, or are damaged, your air conditioner suffers.

Refrigerant Shortages: Refrigerant does not need to be refilled, but some central air systems accumulate leaks. When this happens, refrigerant drips out and contaminates your air supply.

Ice Buildup: When a dirty air filter has been in place for too long, ice can build up around pipes, evaporator coils, or outside of the unit.

Dirty Air Filters: Homeowners can easily change air filters themselves. It’s a simple way to keep your home’s air quality clean while protecting the efficiency of your HVAC system.

Faulty Compressors: When a compressor breaks, amperage increases to keep up with the demands signaled from the thermostat.

Faulty Thermostats: Faulty thermostats are usually older analog thermostats, which cannot keep up with high-efficiency models. Today’s modern thermostats are digital, touch screen, and less likely to have problems communicating with the rest of the system.
