If you live in Texas, you know that having an air conditioning unit is a must. Without it, even doing the most ordinary things (like breathing) can get uncomfortable, and there’s nothing worse than your AC suddenly not working.
Here are eight common air conditioner problems that you might face and ways to fix them (and avoid them in the future).
- Bad Capacitor in Condenser Unit: The capacitors located in the condenser can fail and is one of the main reasons your unit stops working. There are two capacitors in the condenser: the start capacitor and the run capacitor. The start capacitor will provide energy to activate the motor. The run capacitor will help the motor to keep running. If they burn out, the AC won’t function properly.
Luckily, it’s easy to buy new ones. Make sure to read the existing capacitor labels and voltage. To determine if the capacitor is dead, you may need to use a meter to check the voltage.
You can extend the life of your capacitor by keeping the compressor and its coils and the furnace filter clean.
- Low Refrigerant: Another common problem is your AC getting low on refrigerant. The air conditioner is a sealed system, so the same amount of freon keeps circulating. If the unit is low on freon, there’s probably a leak. The leak might be in the compressor, the A-coil on top of the furnace or the pipes between them. Leaks around the unit can cause many other problems, like freezing the A-coil.
There are two possible solutions. One is to replace the whole unit. The other is to call a technician. You may find that he will have to top up the refrigerant every season.
- Clogged Condensate Drain Line: If your AC is working fine, but there’s water around the furnace, the condensate drain line is probably obstructed. To fix that, take the drain tube out and blow it clear. You can unscrew the fitting and clean the inside of that as well.
- Bad Control Board: A bad control board can send mixed signals to your AC. For example, not sending power to the compressor when the thermostat is set to cool; having the furnace working while the AC is on; not turning the blower motor on, causing the A-coil to freeze.
In that case, the control board must be replaced by a qualified technician.
- Fan Condenser Motor Not Working: When you turn your AC on and the fan in the compressor doesn’t work, it could be a faulty motor. An HVAC specialist would most likely replace the motor and probably change the capacitor as well.
- Bad Blower Motor: Sometimes, the evaporator blower stops spinning. The problem might be the blower wheel itself or its capacitor. It’s recommended to call a technician. They would probably replace both the capacitor and the blower motor together.
- Tripped AC Circuit Breaker: If you reset your breaker and it trips again not long after that, there’s probably a short in the unit. It might be a broken or corroded wire touching metal causing the short, perhaps in the compressor or the evaporator. It’s best to call a technician to find and repair those wires.
- Keep Everything Clean: A dirty furnace filter and condenser coil may cause problems with your air conditioning unit. It may stress the unit, waste energy, and cause parts and capacitors to fail early. Cleaning the coils and replacing the filters really goes a long way to extending the life of the unit.
