HVAC Troubleshooting Steps to Avoid Needing Las Vegas Vegas AC Unit Repair

While mild weather persists in Las Vegas throughout the winter months, hot days are never far away. Running your HVAC unit all summer long can take a toll on your air conditioners performance and drive your utility costs up.
You may have noticed some problems over the summer such as your unit not blowing the cold air you may be used to enjoying. Before you pick up that phone and schedule a Las Vegas AC Unit Repair, take advantage of a few HVAC troubleshooting tips first.

The key is a successful troubleshooting examination of the symptoms as to why your AC unit is not performing. Such symptoms may be a lack of air flow coming from the air registers in your home. Troubleshooting common AC problems is fairly easy to perform and is something you can do yourself by following these simple steps:

Step 1

Your first step is to check your thermostat to see if it is operating properly. Turn the AC switch on to cool and set the temperature setting five degrees lower. After a few moments, the system should come on. If it doesn’t then check to make sure that the circuit breaker has not been tripped. The blower unit inside and the outdoor condensing unit should come on if the circuit breaker is operating properly. If both units are working properly, then move to the next step.

Step 2

Inspect the outdoor condensing unit coils next. If the condenser coils are dirty, clogged with vegetation or other yard debris then remove any debris away from the unit. Gently wash the condensing coils with a garden hose. Do not use a pressure nozzle as this could damage the coils. If the unit is exceptionally dirty then consider purchasing a can or two of condenser cleaning spray.

If the outdoor unit persists on not working, the refrigerant may be low or leaking. There may even be a problem with the compressor. In the event that the outdoor unit is not operating, you should consult an AC unit repair technician to further diagnose the problem.

Step 3

If the outdoor condensing unit seems to be operating normally, then move indoors to check your blower unit. If it is not blowing air, turn off the power and inspect the electrical connections to the blower motor. If they appear to be connected and free of any corrosion, check the fan belt on the blower motor to ensure that it is tight. Adjust as necessary. If none of these steps work, the blower motor may need replacement.

Step 4

If the blower motor is functioning properly then examine the copper tubing leading to the outdoor condensing unit. If there is any ice or frost buildup on this line then shut off your system for at least two hours while running the blower unit. The copper line should defrost within this time.

Turn the AC system back on and check the outdoor copper tubing again. It should feel cold to the touch and have condensation on it. If you do not notice any condensation on the copper line there may be a refrigerant problem.

If none of these steps get your AC running properly, you should call a Las Vegas AC unit repair professional at Instant Air to diagnose your HVAC system.
