Some Common Cooling Problems and How to Fix Them

Summer is here, finally! Will you be using your central air conditioning?  If so, there are some common issues that crop up with the systems.  Here are some tips to try before calling for service.

- Not Powering On.  Check to see if your a/c breaker has tripped or the fuse has blown.  If so, turn the a/c to "off" and flip the breaker back to the on position or replace the fuse.  Turn the a/c on again.  If it still doesn't power on, it's time to call for service.

System Does Not Produce Cool Air.  The most common reason for this is a dirty, clogged air filter.  The filter keeps debris from getting into the cooling system and from blowing dust into the air inside your home.  Neglecting to clean the filter means the air won't be able to flow properly through the vents, freezing the evaporator and blocking the production of cool air.  You can easily alleviate this problem by cleaning the filter.  If your system has a removable filter, just remove it and blow the dust out of the filter.  If you have a waterproof filter, you can wash it and then replace it when it is clean and dry.  If your filter is not removable, call a service technician to take care of cleaning or replacing the filter.

- Thermostat Not Working Correctly.  There's nothing worse than turning your a/c to a cooler setting and not getting cooler air!  Double check to be sure you have set the thermostat to the desired temperature.  If so, then try setting it to auto mode. If that doesn't work, it's time to call for service.

- Leaking.  The a/c may drip because of an overflowing or cracked drip pan.  It's easy enough to replace a cracked pan or tilt it to allow condensate to flow out.  It could also be a clogged condensate drain line.  You can clear the line by using a stiff wire bruch inserted into the line, or try sucking out algae and leaves with a wet/shop vac.  If you suspect the unit is leaking refrigerant, you'll need to call for professional help.  

- The Bottom Line.  Regular maintenance is key.  Whether you do it yourself or hire a professional, be sure to perform annual maintenance.
