"Our service tech, Brydan was such a nice young man. Knowledgeable, caring, and such great manners."
"Came home from out of town during the winter storm to a heater that wasn’t working and a house that was 50 degrees inside. With a toddler and an infant in the house I needed it fixed asap. Called Donald Guy and they had a technician out within an hour who was extremely professional and thorough in diagnosing and fixing the issue. I’ll recommend Donald Guy to anyone that needs HVAC maintenance and will call them again next time I need it too."
"Professional, informative and friendly folks. They addressed each new issue and answered our many questions! Thumbs up!"
"I have used Donald Guy for a long time. They are very responsive and are priced fairly. They have performed services calls on my furnace and a/c condenser. They have serviced my mini splits. The technicians are always professional and friendly. I would highly recommend this company for all residential HVAC needs."
"Very professional and answered questions and even made a suggestion to increase air flow on the return"
"No heat and 20 degree nights, they came fas and resolved the problem quickly, the technician was very polite and informative."
