If your central air conditioner will not cool but you can hear it running, it may just need to be cleaned. Whether or not this is the cause of the problem, it’s the first remedy to try. Plan to do this on a relatively warm day. The following are guidelines; always refer to your owner’s manual. 1Turn off the power to the AC unit. There is normally a shut-off or disconnect panel on the wall next to the outdoor compressor. Also shut off the air conditioner’s 240-volt circuit at the main electrical panel. 2Rake leaves and debris away from the outdoor condenser. Trim any bushes that might block airflow. 3Unscrew and remove protective grilles and the top cover or grille from the compressor. If the fan is attached to the grille, be careful not to pull any wires loose. 4Use a soft brush to clean dirt and debris from the fins, and then vacuum the fins with a brush attachment (taking care not to damage them). 5Use a hose and nozzle with a trigger grip to spray debris from the fins (from inside the unit).

Protect the wiring and motor from water with plastic sheeting or a large plastic garbage bag. If your owner’s manual calls for lubricating the motor, do that now—but don’t over-lubricate. 7To test it, turn the thermostat to OFF, reset the power at the disconnect next to the compressor and the main panel, and then set the thermostat to ON. To avoid straining an air conditioner’s compressor, wait at least five minutes between turning it off at the thermostat and turning it back on. Let it run for a few minutes, and then feel the two pipes that connect the condenser unit to the air handler (slide any insulation back). One should feel warm, the other cool.

When it is not, which of course occurs on the most brutally hot day of the year, the A/C suddenly becomes a cruel joke, blowing warm, stale air into your vehicle. If your air conditioner is blowing warm air, or just not working properly, it is best to schedule a service ASAP to maximize your comfort. Schedule Your Next A/C System Service Automotive A/C systems have certain intricacies in their design that render them difficult to repair without the proper equipment and knowledge base. On top of that, there are certain environmental concerns involved with refrigerant that require special attention. We’ve identified three common A/C System issues to help supply you with information on what may be going on with your vehicle. Three Common Occurrences that could Result in your Vehicle’s A/C not Working Properly:Refrigerant Leak A refrigerant leak is unique in the sense that refrigerant evaporates instantly into a gas once it isn’t under the pressure of your closed loop A/C system. A/C systems are sealed and therefore don’t require refrigerant top-off’s.

If the refrigerant level is low then there is a leak that needs to be addressed Leaks in your A/C don’t result in the normal tell tale puddles of fluid under your vehicle like those of an oil or antifreeze leak. Our certified technicians are trained to search for much less sinister signs of leaks like the oily residue which might be found on or around A/C hose units or connections. A refrigerant leak can also occur in the A/C compressor, condenser, and/or evaporator - essentially all of the components of your air conditioning system. We employ state of the art leak detection methods including UV dyes and specialized test equipment to ensure that your car is properly diagnosed the first time and serviced right, complete with our nationwide warranty. Worn out compressor The compressor is the heart of your vehicle’s air conditioning system. Its function is to circulate refrigerant through a series of stages that allow it to remove heat from your vehicles cabin. Similar to many other car parts, the compressor can wear out over time.

Due to its complicated design, compressor failure can be attributed to contamination or other failed parts within the system. There are some things that you can do to help prolong the life of your vehicle’s compressor. First, make sure to run the compressor for about 10 minutes once a month in the off season, regardless of the temperature outside. This is easy to in most modern vehicles since they utilize the compressor when the defroster, which is used year round, is activated. Another way is to stop in to Pep Boys for a FREE A/C Quick Check (not available in the state of California) and an associate can give a visual inspection of the compressor to ensure that everything looks in order.Problems with the electrical system The A/C system in your car has a maze of wires complete with fuses, relays and pressure switches that work in unison to provide safe operation under normal operating conditions. If one of these electrical components fail due to age or defect, the system is designed to shut itself down to prevent damage to itself or unsafe conditions for the operator.
