In the summer heat, a malfunctioning air conditioner can quickly turn your home into an uncomfortable sauna. Before you start sweating bullets, try these expert troubleshooting tips to get your air conditioning system back in working order. Sometimes, a little DIY effort can solve air conditioner problems and save you from having to call us for air conditioning repairs.

Check the Thermostat

The first step in troubleshooting your air conditioner is to ensure that the thermostat is set correctly. Make sure the thermostat settings are on “cool” and set at your desired temperature. If the thermostat is battery-operated, try replacing the batteries.

Check the Circuit Breaker

If your air conditioning unit suddenly stops working, check the circuit breaker to see if it has tripped. Reset the breaker if necessary and monitor the AC unit to see if it starts working again. If the breaker continues to trip, there may be an electrical issue that requires professional attention.

Inspect the Air Filter

A clogged or dirty air filter can obstruct air flow, causing air conditioners to work harder and less efficiently. Check the air filter regularly and replace it if you find a clogged air filter. This simple maintenance task can improve the performance of your central air conditioner and extend its lifespan.

Clean the Condenser Coils

Over time, dirt, debris, and grime can accumulate on the condenser coils in the outdoor unit, hindering heat transfer and reducing the efficiency of your air conditioner. Use a soft brush or vacuum cleaner to gently remove any dirt or debris from the condenser coil and fins. Be sure to turn off the power to the unit before cleaning.

Clear the Condensate Drain Line

A clogged condensate drain line can cause water to back up into your home, leading to water damage and mold growth. Turn off power to your central AC unit and locate the drain line below the evaporator coil. Use a wet/dry vacuum to remove any blockages. Regularly flushing the drain line with water can help prevent clogs.

Test the Fan Motor

If your air conditioner is running but is blowing hot air into your home, the fan motor in the furnace or air handler may be malfunctioning. Turn off the power to the unit and carefully inspect the fan motor for any signs of damage or wear. You can also test the motor using a multimeter to check for continuity.

Check for Air Leaks

Inspect the ductwork and seals around windows and doors for any signs of air leaks. Leaks can allow cold air to escape from your home, reducing the efficiency of your air conditioner. Use weatherstripping or caulk to seal any gaps and improve energy efficiency.

Schedule Regular Maintenance to Prevent Air Conditioner Issues

Preventative maintenance is key to keeping your air conditioner running smoothly and efficiently. Schedule annual maintenance appointments with Ravinia Plumbing, Sewer, Heating & Electric to clean and inspect your AC unit, identify any potential issues, and keep it in peak condition. Preventative maintenance can often save you from common air conditioner issues, such as the ones mentioned above.
