Below is a list of some of the most common air conditioning problems, along with information on how to fix them.


Air Conditioner Will Not Turn On

AC Problems Las VegasSometimes an AC unit will not come on, despite the fact that the fan in the home is working. One reason for this is a faulty thermostat. Check to see if your thermostat is working properly. Broken thermostats can cause the entire air conditioning system to fail. In this case, call Moore Air Conditioning and Heating. Our certified technicians can quickly repair or replace your thermostat and restore your home to a comfortable state.

Another cause of the problem could be your home’s circuit breaker or a circuit breaker outside near your air conditioning system. If it appears that either breaker has tripped, attempt to reset it and try to turn on your air conditioning unit. If the breaker trips again, do not reset it. Call an electrician immediately to diagnose and fix the issue.

Overgrown vegetation is another common reason that air conditioning units fail. Excessive leaves, grass and other debris can be easily drawn into the vents of your system, where they can cause damage to the A/C capacitor. In this case, it is important to call us for service. We will be able to safely clean the unit, and either repair or replace the capacitor.

Air Conditioner is Making Noise

Although it is commonplace for air conditioning units to make noise while they are running, certain types of noises can indicate a problem. If you are experiencing loud vibrating or rattling sounds, you should schedule an inspection of your AC unit. When air conditioners are installed incorrectly, they may make these types of sounds.

If you have an older air conditioner and you hear squealing noises while it is running, most likely the motor is a belt-driven motor and the belt connecting the blower to the motor has slipped. You should shut your air conditioner off and call us. Our certified technicians will be able to provide you with a definitive diagnosis and give you recommendations for solving the problem.

AC Runs But Does Not Cool Your Home or Office

If you feel neutral or warm air flowing through your vents when your air conditioner is running, there are three common reasons for this malfunction. First, the unit’s condenser coil may have stalled. The coil is the component of the AC system that produces cold air, and the condenser fan may continue to run even if the coil stalled. A tripped circuit breaker or blown fuse may be the cause of this. Second, low refrigerant may prevent your air conditioner from producing cold air. Third, you may have a leak in your air duct system that is allowing cold air to escape before reaching the registers. In all three cases, Moore Air Conditioning & Heating will be able to assist you with inspections and repairs or replacements.
