Awesome service. Furnace was out when I woke up the other day when we had our last snowstorm. Duffey's had my furnace running again within 3 hours of me waking up to a 63 degree house. Fast, friendly and good pricing!

We called Duffey's after a previous well-known A/C repair company wanted to charge us thousands of dollars for a full replacement. Duffey's was responsive, patient, and knowledgeable, saving us thousands of dollars. Since then, they're our first call for an annual visit: the work they've done to keep our older equipment running has been nothing short of miraculous. I recommend them without hesitation.

My ac has not worked in 8 years. I have had several repair companies out with not much luck except the option to buy a new unit.
Duffey's came out early, found the problem in 5 minutes, had parts with them, and for the first time since moving into this house, was able to get the temp in my house to 74 degrees on a 100 degree day. I will be using them for any hoax need and strongly recommend them.
