Common Air Conditioning Problems

While there are a number of things that can go wrong with your HVAC systems, there are a few pretty common ones that we see all the time. And then there are a few general tips that that will REALLY help improve your world and make your life a whole lot more comfortable.

Digital Thermostat saves you money!Cool only the needed areas

“Were you raised in a barn??” If we had a buck for every time most of us heard that as kids… In the event your air conditioner is on, don’t forget to close your property’s windows and exterior doorways. For room air-conditioners, isolate the space or a group of connected rooms whenever possible from the rest of your house.

General Air Conditioner Problems

Other general difficulties with existing air conditioners derive from faulty unit installation, poor support procedures, and inadequate care. Many occasions, the refrigerant charge (the sum of refrigerant within the system) doesn’t fit the manufacturer’s specs. If correct refrigerant charging isn’t performed throughout installation, the operation and effectiveness of the unit is impaired. Unqualified service technicians often don’t find refrigerant charging problems or even worsen existing problems by adding refrigerant to a system which is already full. Learn what things to require when employing a tech to keep up your air conditioning.

Air conditioner suppliers generally make rugged, high quality units these days. In case your air conditioner fails, start by checking any fuses or circuit-breakers. Allow the unit cool off for about five minutes before resetting any breakers.

Refrigerant Levels

In case your air-conditioner is running low on refrigerant, either it had been undercharged at installation or it leaks. If it leaks, simply adding refrigerant is not a solution. An educated technician should repair any leak, test the repair, and then charge the system together with the correct amount of refrigerant. Refrigerant leaks can be dangerous for the environment.

Substandard Maintenance

If you let filters and air-conditioning coils to eventually become dirty, the air conditioner won’t operate properly, and the compressor or enthusiasts will likely fail prematurely.

Electric Control Failure

The compressor and fan controls can wear out, especially when the air conditioner turns on / off often, as-is common whenever a system is over sized. Because corrosion of wire and terminals can also be an issue in several structures, electrical connections and contacts should be checked in a specialist service call.

Sensor Problems

Room air-conditioners have a thermostat sensor, located behind the handle panel, which measures the temperature of air coming to the evaporative coil. If the sensor is knocked out of position, the air conditioning could cycle continuously or behave erratically. The detector needs to be next to the coil however, not touching it; adjust its position by carefully turning the cable that holds it in position.

Drainage Issues

When it is humid outside, check the condensate drain to be certain it is not clogged and is emptying properly. If not mounted level room air conditioners may not drain properly.
