**HIGHLY RECOMMEND** These guys are so wonderful! They did an amazing job installing our new AC, and they made it very affordable for us as well. Shawn is very responsive and helpful and Mike was amazing at talking us through the installation process. We learned a lot! Look no further, these guys are genuine, honest, and caring and will give you excellent service and a great product. Thanks so much Shawn & Mike!

I was having trouble with my furnace (on the coldest weekend since forever naturally). Mike showed up in about an hour, did a thorough check of the system, set up a work around until a part was available then came back in the evening the day he got the part and installed it. The furnace is not only repaired but works better than it ever has while I've lived here. They are definitely where I'm going from now on. Thanks guys!

We had a great experience with Duffey's today. Our AC suddenly stopped working this morning and within a short time our house was getting pretty uncomfortable. I called and left a voicemail and received a call back in a short time and was able to make an appointment for the same day, within a couple of hours. The technician that showed up was very professional, was wearing a protective face respirator and kept his distance while in our home. He was able to quickly diagnose and fix our issue and the cost was reasonable. I highly recommend!

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.

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.
