“Best service I have ever received.”

GMH exceeded my expectations in a service provider. They showed up on time and were very friendly. They took the time to explain what they were going to do and what I should expect when they were finished. ”

Gave estimate for a new unit, temp fixed, replaced old unit with a new energy efficient unit.They were quick and professional. Called to inform us when they would be out and were on time. Did a great job and would recommend them! 🙂

I had an issue with very high power bills this winter. They came out and explained all my options and how I could even switch over to a gas furnace. The guys did a great job, they were very polite, clean and took care of us. I would recommend them to anyone.
