Daryl LysengMay 19, 2026 Today Peter and Nathan came by to replace the Flame Sensor and ignighter in my Navien and do a maintenance on my Trane Air Conditioner until - and they also readjusted my Trane Thermostat. Peter took the time to explain features of my Navien and the Trane unit and answered every question I had about both systems. I really enjoyed the time they spent here and learned a lot today. November 12, 2025 Brian arrived on time and quickly got to work installing my new Trane XL 850 Thermostat. The installation was a bit tricky because I had run the CAT 6 cable to the wrong side of the thermostat. But Brian was very patient and explained what he was doing the entire way. Brian also answered all of my questions when he serviced my Trane Furnace and my Navien Tankless system In the early Summer, I'm booking him to service my Air Conditioning unit as well.Trustindex verifies that the original source of the review is Google.
