Central Air Repair Guide

Central air conditioners are greatly helpful when it comes to giving comfort to the entire house at one go. However, the problem arises when the central air or the central air conditioner of your house faces some operational problem. It is then that homeowners or business owners runs from pillar to post to make the system operational once again. Most of the times, it is seen that when central air conditioners stop functioning homeowners get in touch with HVAC contractors who put in their expertise and make the systems operational once again. Nevertheless, sometimes there may not be the need to call in a HVAC contractor, rather using a few DIY methods homeowners can put the system right.

The first thing that you need to keep in mind while you experiment the DIY methods in your central air conditioner is to turn off the power in the first place. You need to make sure that the problem is not with the furnace. You will have to set your thermostat to A/C mode and lower the temperature setting. If you see that the furnace fan kicks in, then you can be sure of the fact that the problem is not with the furnace. In case the furnace do not run, then, you can try resetting the furnace circuit breaker. Even after these steps, the system still does not run, you need to call in an HVAC expert.

The next thing that you could do is to check the condenser. In case the condenser of your system is not running you could check for blown fuses or tripped circuit breakers at main entrance panel or at separate entrance panel and accordingly restore the circuit. You could also try lowering the thermostat. When all these tricks fail, getting in touch with a professional is recommended.

The other important things that you can try out before calling in a professional is cleaning the evaporator and the filter. This is because a dirty evaporator and a dirty filter cause higher wear and tear on the machine and that in turn might lead to the inefficiency of the machine. In fact, you can even try cleaning the condenser before an HVAC expert comes to take care of your system. In order to clean the evaporator, you will need the following:

• Screwdriver
• Stiff brush
• Large hand mirror
• Household bleach and
• Wire

In order to clean the condenser one would require:

• Grass shears or pruners
• Spray bottle of coil cleaner
• Soft brush
• Fine comb
• Carpenter’s level
• Pry bar
• Gravel or rocks

Besides you can visually examine all the duct work associated with the central air conditioner to find out whether it has become disconnected or crimped. This include checking duct work even in the most difficult areas like the basement or the attic.

After all these trial and error methods if the central air conditioner refuses to function, you will have to call in an HVAC technician from a reputed agency. Last but not the least, in case of central air conditioners getting it checked two times in a year is a recommended thing to do.
