Phil :

Hello, .lightening storms can damage electronics controls. Does the stat still work to operate your system in cooling and heating mode.?

Customer:

yes i think so. i can turn on fan and air conditioning seems like compressor not functioing as usual. cool air comig from the fan outside the compressor.

Customer:

an airconditiong service can come tomorrow but it will probably cost me.

Customer:

is there a way to reset the system

Phil :

The compressor is off, could be an electronics control card issue.. due to the electrical storm. or a burnt out compressor etc. If you have a multi meter we can check a few things before the tech arrives... that will help you in dealing with him.

Customer:

no multimeter

Phil :

in that case wait for the tech.. hope he is sharp...if he whips out a multi meter right off to verify power to the unit, then kills power to the unit and uses the meter to look for a short..he is on the ball and his diagnosis is probably pretty good.... if he fumbles around that will be a sign he is short a clue or two.

Phil :

tell me how old your unit is and i can provide some more insight on what may be wrong with it.

Customer:

house built in 2002 air bear filter changed every four months. never needed service.

Thanks for the accept AND the tip! the unit is 8 years old, over due for fan motor failure, lets hope its that, and close to the end of the compressor life as well, if the repair cost is over $200, stay in touch I will give you recommendations on how to get a good deal on a new unit.
