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.

I have used Duffey's to repair our AC and furnace. I also had them replace our water heater. Shawn and his team are very friendly and prompt. Their pricing is very good and the service is top notch. Will continue to use them for all of my HVAC needs.

Duffey's did a wonderful job replacing my furnace. Their quote was reasonable and they were done in one day. The Douglas county inspector also said that the installation was very good.
