“I recently had to replace HVAC and furnace. Scotty has been my go to person for many years. Always polite and cheerful. He informed me it was time to get the units replaced. I had been dragging my feet for a while. I took the plunge and had both units replaced. The two guys (Nick was one. Unfortunately I did not get the other person's name.) They arrived about 10:00 AM and never stopped until after 5:00PM. Did not take any breaks, just kept their heads down and worked hard. Very cordial and happy folks. Explained everything they were doing. Thank you.”

In addition to seasoal changeover from heat to AC, he offered expert advice for overcoming a long-time problem of thermostat location simply and based on existing smart Honeywell units. Evaluated UV bulbs and other technology. Really intend to ask for him for future service needs.”
