A new air conditioner can expect to give you between 10 to 20 years of service, but problems that require AC repairs will crop up casually. Most air conditioning repair problems involve minor repairs that can be done at home. For instance, you can do simple central air conditioning troubleshooting at home. If your central air conditioner runs, but fails to cool effectively, the unit may just need cleaning. Turn off the main power supply to close all power to the unit. Remove the protective cover from the condenser fins, and clean dust and dirt, vacuuming with a small brush attachment. Remove the topmost grille, and hose the fins inside the unit. Place all the parts back together, and switch the air conditioner on. If you still don't see any improvement, call an AC repair technician to perform air conditioner troubleshooting.
A unit that frequently needs AC repairs is the result of poor air conditioner maintenance. You can increase the efficiency of your unit and increase its life span by regularly cleaning the filters and replacing them. Filters that are blocked with dust and debris block the air flow, and drag down the efficiency of your air conditioner. Dust laden air may carry these particles into the evaporated coil, and affect its capacity to absorb heat. It's recommended that you get your air conditioner filters replaced, or cleaned at least once or twice during peak season. Pay more attention to your filter if your HVAC system sees heavy use or a dusty environment. If you notice water accumulation near the air conditioner, it might be the result of a leaky tube if you can locate a leak in the tube, get the tube replaced. If not, it may be a more complicated problem with the pump. Frequent central air conditioner repair problems can also occur if you have the wrong size unit. For instance, in an oversized unit, the AC may switch on and off frequently, wearing out the fan motors and compressor.
