Do I need a service call?

Today I wanted to talk about troubleshooting airconditioning systems, I have customers call me and ask me and say my thermostat is not working, I'll ask to go to their Honeywell thermostat and check the buttons on it to make sure it is set correctly, depending on the time of the year. Last go and look at the fan switch and make sure it's set to auto instead of on, because the motor is not designed to run constantly. You have to keep in mind that the system has a built in time delay as a safety feature to protect the line set from back flooding the compressor get a chance to equalize. Another common problem that causes the air conditioner to now have power is the breaker’s tripped, for this check your electrical panel box, in this case it is a Cutler Hammer panel box, some other common brands are GE, Square D and ITE, they all operate the same way, make sure your breakers are on the ON position. It is very important to know how to pull the thermostat cover off the wall and to check the batteries. Next I tell my customers to go to their air handler and to check the float switch, you usually have two white pipes at the air handler and one of those has a safety switch attached to it. The last and most important thing to check is the filter, a good tip is to put a date on the filter to remember when it was last changed.

Thanks for watching!
