**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!

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.

We had an excellent experience using this company with same-day service and a quick assessment of the problem by Mike, the technician. He replaced the needed parts that day at a reasonable price.

Super helpful, knowledgable and honest. Their experience paid off in terms of saving me a LOT of money over what I could have spent on my heating problem.

Our HVAC in our new house stopped working during a set of 90-degree days. Duffey's quickly scheduled a same-day appointment, and Tim came out to service the HVAC. He was polite, professional and friendly. He explained the problem, offered a simple and long-lasting solution, and fixed the unit within a few hours. He also answer numerous (likely naive) questions that I had. I would (and will) use Duffey's in the future; it was an excellent experience.

Shawn is a professional. Did the furnace replacement job well and quickly so we could get thru inspection and sell our house. Fair prices and locally owned so we continue to refer him to our friends.
