I called at about 6:45 AM and left a message and my call was returned before 8 AM the same day. They had a service man there by 9:15AM and after he had a chance to inspect it, it turned out to be loose. Return vents. They charge me less than most HVAC trip charges and could've easily sold me a new blower. They are my go to person for HVAC.

Unfortunately, our unit and house had bigger issues. The service technician, Jeff explained all of our issues to us and answered all of my questions. We ended up needing a new unit and some ductwork done. Within a week our new unit was installed by Mike and his guys and I couldn't be happier or WARMER!! I would highly recommend Duncan Heating and Air to anyone if you want an honest company and fantastic people to deal with.

They did not seal the duct work properly, drain tubes too short and leak. Called them to come back out 3 times, spoke to (wife?) and they never returned my calls or came back out.

The team was professional, polite, and aware of keeping the space clean and neat. The service was prompt and calls returned were timely even after hours. Pricing was more than fair and no surprises beyond what they originally quoted. The service technicians named Wes and Dillan went beyond and above our expectations. Needless to say our home was built 10 years ago , so first time having an AC problem we feel we chose the correct company to get the job done and we would recommend highly.

Had a problem with our downstairs AC unit. Another company diagnosed it with an expensive repair…read more.. I wasn't convinced. I called ECS for a second opinion. Buck came out and looked at the system and came up with a plan. He knows Carrier units and is a total expert. His plan was a fraction of the cost and he got to the root of the problem rather than just guessing like the other company had. They were timely and honest and had a fair price. That's hard to find these days and I highly recommend them.

The options were clear, honest and straight forward. While the recommendation was to replace it, there was no high pressure and Buck was always sensitive to the costs involved with each option and the benefits and long term vs short term costs. We decided to replace the system. His price was fair and better than the bigger outfits. His crew was great and their attention to quality matched or exceeded the best around. We couldn't be happier with the whole process. Buck makes you feel like a customer not just a sale.

There was only one time when there was a hiccup where the small repair didn't actually do the trick, but the next guy who came along addressed it. They respond over the weekends, and most recently Sean (maybe Shawn?) called us and talked us through the small items needed to fix it ourselves, which saved them the trouble of coming out and saved us the after-hours up-charge. (And saved our discomfort for not having A/C for a day!)

Gave me a list of what was wrong with our unit. Because of his bad attitude, I had another company come out to check the unit. They were very friendly and showed me everything they were checking for and the results. Most of what Stiles' service man told us was absolutely wrong. Example, he told us we had no Freon in the unit (knowing that it was filled the day before he came by a family member). The second company SHOWED me that we had Freon in our unit.
