5 Common AC Problems in Residential Homes and How to Fix Them

Air conditioning becomes an essential component of many residential homes as temperatures rise during summer. However, AC units can experience problems and malfunctions like any other home appliance. Here are five common AC problems that homeowners may encounter, along with tips on how to fix them:

Dirty Air Filters

Dirty air filters are a common AC issue. Dust, grime, and other debris can clog air filters, reducing airflow and system efficiency. This can strain the AC unit, raising energy bills and risking system damage.

The solution is simple: regularly replace or clean the air filter. Do this every 30-90 days, depending on the type of filter and the level of use. To replace the filter, turn off the power to the unit, remove the old filter, and replace it with a new one. If the filter is washable, remove it and rinse it thoroughly before reinstalling it.

Refrigerant Leaks

Refrigerant leaks are another common problem with AC units. Leaks can occur when the refrigerant lines become damaged or develop cracks over time. When this happens, the AC unit may be unable to cool the air as effectively, leading to warm air blowing from the vents.

A professional Residential AC repair expert should be contacted if you suspect a refrigerant leak. Attempting to fix the problem yourself can be dangerous and may damage the system further. A professional technician can diagnose and repair the leak by adding more refrigerant.

Faulty Thermostat

The thermostat is the control centre of the AC unit, regulating the temperature and turning the system on and off as needed. If the thermostat is faulty or not calibrated correctly, it can cause the system to malfunction.

To fix a faulty thermostat, check the batteries and make sure they are fresh. If the batteries are fine, try resetting the thermostat by turning off the power to the unit and then turning it back on again. The thermostat may need to be replaced if none of these steps work.

Blocked Condenser Coils

AC condenser coils release heat. Dirt, debris, and other obstacles can clog these coils, decreasing system performance..

To fix this problem, turn off the power to the unit and remove any debris or obstructions from the coils. You can use a soft brush or vacuum to clean the coils, being careful not to damage the delicate fins.

Clogged Drain Line

The drain line is responsible for removing condensation from the AC unit. with time, this line can become clogged with dirt, mould, and other debris, which can cause water to back up and potentially damage the system.

To fix a clogged drain line, turn off the power to the unit and locate the drain line. Carefully remove debris from the line using a wet/dry vacuum or a pipe cleaner. You can also pour a mixture of bleach and water down the line to kill any mould or bacteria.

Conclusion 

Finally, these AC issues are frequent in homes. For more complicated Residential AC repairs, call a professional. Regular maintenance and inspections can prevent these issues and keep your AC unit running smoothly all summer.
