Homeowner Tips For Air Conditioner Repair

It can be annoying and uncomfortable if there is a mechanical issue with your air conditioning system, especially in the sweltering summer. However, before contacting a professional HVAC contractor, you can try some basic mechanical air conditioner repair tips to avoid costly repairs and replacements. Here are some detailed tips to help you diagnose and repair mechanical issues with your AC system:

Tip: Check the Thermostat

The thermostat is the first thing to check if your air conditioner isn't working. Check that the thermostat is set to the appropriate temperature and mode for the season. In the summer, set it to a comfortable temperature and use the "cool" mode. Also, inspect the thermostat's batteries and wiring to ensure they are not damaged or corroded.

Tip: Clean the Condenser Coils

The condenser coils in your AC system are in charge of releasing the heat absorbed by the refrigerant. The coils can become dirty over time, reducing the efficiency of your system. This can cause your system to overheat or even fail. To clean the coils, turn off your air conditioner and remove any debris or vegetation from around the outdoor unit. Then, using a soft brush or a special coil cleaning spray, remove the dirt and grime from the coils.

Tip: Check the Fan Motor

The fan motor in your air conditioning system is in charge of circulating air over the evaporator and condenser coils. If the fan motor is not working, your system will not be able to cool your home. Turn off the power to your AC system and inspect the fan motor for any signs of damage or wear. Also, inspect the motor's wiring to ensure it is not loose or corroded. If the motor is damaged or not working properly, contact a professional HVAC contractor to replace it.

Tip: Inspect the Capacitor

The capacitor in your AC system provides the electrical charge to start the compressor and the fan motor. Over time, the capacitor can become weak or damaged, causing your system to struggle to start or not start at all. Turn off the power to your AC system and look for the capacitor near the compressor to check it. Check the capacitor for any signs of bulging or leaking. If the capacitor is damaged or weak, call a professional HVAC contractor to replace it.

Tip: Inspect the Refrigerant Levels

Lastly, the refrigerant in your AC system is responsible for absorbing and releasing heat. If the refrigerant levels are low, your system will not be able to cool your home efficiently. To check the level of refrigerant, call a professional air conditioning repair contractor to do a leak test and, if needed, recharge your system. Never attempt to add refrigerant on your own, as this can be dangerous and could damage your system.
