Ac broken - could it be technician's fault?

Question

Last summer I had a problem with the blower on my furnace (AC was on at the time). Tech came out and said it was a board, replaced board and it broke twice more; last time it was "bypassed" somewhere to keep the air continuously running. Turned out all along it was that the blower motor was getting over-circuited or something and this is why it only worked when something was bypassed. Well, supposedly fixed and ran air fine for one day but when I came home after 8 hours house was warm, air conditioner was ON but blower wasn't - the blower went out and the air kept going and the condensation from the FROZEN pipes ran down the furnace and blew the whole board they just put in. I was very concerned about my air running that whole time and leary that it would have problems, too. Had to replace furnace alltogether and still concerned about ac. I didn't run the air until today. Now the furnace blower works but the fan inside the AC doesn't spin and no cold air is being produced.

Answer 1

did anyone have the sense to look at evaporator coil when you have bad air flow it overamps the board and motor but no the outside fan has nothing to do with it might be a capacitor or fan motor

Answer 2

it very well could be the techs negligance or laziness.  you should never have to bypass anything.  Sounds like a relay problem.  I would call the company that did the bypass and ask for them to send a more experienced tech.  By him bypassing anything it puts your whole household at risk.  It definetly disrupts the safety and proper operation of your system.  Whatever he bypassed was obviously the problem and he should have properly repaired or replaced it.  you shouldn't have to pay for anything more.  document everything and watch the tech, ask questions.  Sounds like you may have a lawsuit on your hands.  Get a professional opinion from a lawyer.

Answer 3

Because of your problems last year it appears you are overthinking it bit at this point.

The furnace and blower is working on a call for cooling so your thermostat is working too.

The outdoor unit is not running. Other than the 24 volt wires going to the unit that unit is entirely separate, electrically.

They should have a box on the outside for that unit with a shut off. Since this is the first you tried it it could be shut off. Some have fuses or a breaker in that box.

AND that power comes off a breaker on the main panel. It could be any of those could be off, tripped, or a blown fuse ("slow blow" 50 or 60 amp usually). They very easily could have shut those off while replacing the furnace. But they should have tested it.    

Once you verify it has power then it could be that the shorted furnace board took out the contacter that turns the outdoor unit on and off. That is in the condenser unit. Or another component in that unit is out.

You can't start to assign blame until you find out what the failure is.

Good Luck.
