Just moved into the house with a Lennox system. I tried to switch out the thermostat and it don’t agree with the system and messed up everything. Called the company Sunday morning to request service. Henry called a couple of hours later and came out. I appreciated how he walked me through what he was doing and explaining the interplay with the Lennox system, etc. He was upfront with the pricing for coming out and then providing the service while he was there. I would definitely use LT and Henry again.
