Stay away from ECM at all cost!
ECM installed a top of the line AC unit in my house that included 10 year warranty. 2 years later the thermostat goes dark. It's one of those sophisticated Lennox iTouch, so I called their service, I was told "parts are under warranty, but labor is not. A diagnostics by our technician is $45"
The guy shows up, within a minute determines is the thermostat is bad. Parts are free, but he wants $250 to replace it + the $45 diagnostics (mind you it's
I call the service desk again and the tell me it's their standard rate :(. Gratuitously they agree to drop the price to $204 + $45.
Since the thermostat costs $150 on the web, I figured I'll do it myself and sent the tech on his way. So much for their warranty
There is no reason in the world why a tech that you already paid to be at your door will charge these brain surgeon rates. ECM is simply scalping their customers. I would never use them again and suggest you do the same
