Furnace & AC install, AA600, t4 stat
Replaced circuit board due to the phantom errors unit was having. I asked customer if it had ever locked out and was blinking red and no heat she explained no but every time she had turned her thermostat off there would be a wrench on the screen ther errors listed were all the same sp1 first ignition failure. I’ve tested co #s with combustion analyzer and all within range per manufacturer recommendation. Once board was replaced set up all parameters per manufacturer specs when replacing the board. We tested the unit and operation of the system is normal. No charge warranty
I talked to Curt. He said we were going to put a new furnace in and he’s gonna bring a new AC over and we will install that. Also there will be no charge for the service call. we need to call and schedule this for installation.
Replaced batteries and showed them how to do it
Checked over system owner claimed that it was noisy on startup. I set the gas pressures as low as if they could go according to the manufacturer set up blower speeds cycled and tested final check OK owner does have a 10 year parts and labor warranty.
Bring a 5 gallon bucket of gravel when coming to do AC startup
