Common Air Conditioning Repairs

Air Conditioner won’t turn on

Possible Cause: The thermostat is not set correctly or the power to the unit is off. The fix: Make sure that your thermostat is set to “cool” and the temperature is set to the correct temperature. Some newer thermostats operate on battery power. Make sure it has fresh batteries. You will also want to check your circuit breaker and ensure that the system has not tripped a fuse.

System not cooling the same

Possible Cause: Airflow is essential to cooling your home. System cooling issues can be traced to issues with airflow. The fix: Change your filters regularly. Depending on your lifestyle, the number of people that live in the home, and if there are any pets, the filters should be changed every 30 to 60 days. The outdoor condenser must have a minimum of 24” of clearance on all four sides and top. The condenser can not reject the heat properly if objects are placed directly next to it. You should also check your air supply, returns, and grills for obstructions.

High utility bills

Possible Cause: High spikes in your electric bill can mean that your unit is no longer running efficiently. After the air filters are replaced the most likely cause can be a dirty outdoor condensing coil. The fins that encapsulate the refrigerant line build up dirt & debris and choke airflow. The condenser can not reject the heat efficiently and the system run for longer times. The fix: Unfortunately, to properly clean the condenser coil and remove the leaves and dirt that build up inside the unit, a qualified Complete Pro Air technician is required to ensure that the electrical components and fins are not damaged. Proper refrigerant balance is also crucial. An 18 SEER system undercharged or overcharged with refrigerant by 20% can function as a 9 SEER system, essentially costing significantly more to operate. We also offer programmable thermostats that can set a higher temperature while away during the day to reduce energy usage.

System is loud

Possible Cause: Is your system loud at start up or during normal operation? if the system has not been properly maintained, fan blades, screws, motors, grills can are loosen and vibrate. Other times the noise is caused by a bad motor, bent fan blade, or a worn compressor. The fix: During a precision tune up by a qualified Complete Pro Air technician, these motors, fan blades, screws and grills are adjusted and lubricated to ensure it is running at peak performance. The system pressures are diagnosed and the compressor and supporting parts are examined. Complete Pro Air also offers System Rejuvenation. This service quiets the compressor & valves and helps the system run more efficient. Rejuvenate your system today!

Unit will not kick on

Possible Cause: The heart of the system, the compressor, could be burnt-out The fix: To replace a system compressor is a costly job. It includes replacing several small parts, cleaning out existing copper lines, and installing new refrigerant. Depending on the type of refrigerant in your system, the cost could equal the price of a new system. If the unit is more than 8 years old, we recommend system replacement.

Water leaks by air handler

Possible Cause: The air conditioning system in your home was originally designed to remove humidity and condition the air. Your air handler condensates water on the coil. This water drips down from the coil and collects in a pan, then drains to the outside of the home. If water is found on the floor or ceiling, it is possible that a drain components have build up debri and clogged. The fix: Inspect the drain line outside of the home for a clog or animal intrusion. Often times a clog can be removed by attaching a wet vac and clearing the line. If cleaning this line does not stop this issue, please call a qualified Complete Pro Air technician for repairs.
