Just got my SRP rebate check, which made me rethink my whole 4.5 stars thing. To be fair, I was just reacting to the Trane unit that failed. That's on Trane, not Sure Temp. They took care of everything from start to finish, and shouldn't be dinged for a faulty manufacturer. It's been a month, and everything is working to plan. I appreciate their willingness to work it through until it was right, and doing what they could to express their apologies for something largely beyond their control. Thanks to all of the service guys that came out. 5 stars - unreserved!
