Is $34,000 to replace an 11-year-old 5-ton Lennox AC unit and furnace a fair price?
Project Details
My upstairs 11-year-old Lennox XC 21–0 60–230–11 unit, which is one year out of warranty, quit running and showed a blank S30 screen. After powering down both the air handler and compressor, the unit started running again. However, I then noticed the downstairs unit was not cooling. Powering it down didn't help; neither the fan nor the condenser was running, though there was power to the contactor. I haven't seen any lightning or power surges, and the rest of the house is fine. I'm having trouble finding the motor online as the manufacturer apparently discontinued it, and I'm wondering if there are equivalent ECM motors I can use. Both my upstairs and downstairs units showed electronic problems simultaneously, which suggests some kind of voltage spike. If the motor is bad, I'm wondering if I can assume the control module also went bad. I'm also pretty sick of Lennox after previous coil issues and wonky iComfort thermostats. I think I can install the new disconnect switch myself.
