Common Home Air Conditioning Problems

home AC problems

Sometimes central air conditioners fail at the most inconvenient times like during the middle of a hot summer.  Typically the reasons for failure are fairly easy to rectify or can be prevented with regular maintenance from County Line, LLC heating and airconditioning.

Below is a list of the most common AC problems and what can be implemented to resolve them.

AC System Won’t Turn On

On occasions the air conditioning unit won’t turn on, but the fan inside the home is working fine. First would be to check the thermostat and make sure it’s functioning properly because a faulty thermostat can cause the entire central AC system to stop working.

If the thermostat is not the problem, check the circuit breakers inside your home and outside near the unit. If the circuit breaker trips again after you reset it, call County Line, LLC to repair the problem. Excessive tall grass or leaves around the outside unit can block the vents of your unit and damage the running capacitor.

Air Conditioning Making Excessive Noise & Odor

If you smell an odor coming from your vent, you probably have a air conditioning mold spore problem in the ducts. Typically most air conditioners while they are running make some noise which is normal.  Excessive rattling or vibration could indicate a malfunction of the unit.  In this case, you need your system checked for improper installation if it’s a recent new install. The air handler may be producing a high pitch noise when the air conditioner is running.  This is the part that moves cool air through the ducts in your attic.  If you have an older AC unit, the belt connecting the blower to the motor is slipping making this high pitch sound.  In this situation, turn off the AC unit and call County Line heating and air conditioning to diagnose and repair your system.

Air Conditioner Running But Not Cooling Your Home

If the air coming out of you room vents isn’t cold, you might have a faulty condenser coil but the condenser fan will continue to run. Other possibilities could be low Freon, circuit breaker, fuse or leaking cool air from attic ducts.

Having your home air conditioning system scheduled for annual preventive maintenance by County Line, LLC ensures your unit will run without failure during the hot summer months and avoid costly repair bills.
