Duncan Heating & Air Conditioning Inc

Our AC unit went out a few weeks ago, we called the first company we found online. They told us that the disconnect switch on the AC unit was missing and wires were cut inside the unit. They quoted us $400 to replace the disconnect switch and another $300 for the wires. We called Duncan for a second quote and the tech said, yes the disconnect is missing but the wires are just installed that way on your unit, nothing was cut. He quoted us around $100 to replace to disconnect but was also honest and said we could do it ourselves with parts from the Home Depot. Great, honest company that values it’s customers!

Highly recommend Duncan. They always do a great job. New unit installed. Quality work. Professional. Trust worthy company and technicians.

So thankful for Duncan Heating and Air! We had had another company look at our unit over three times and never told us about some serious issues. We would have never known if it wasn’t for Duncan Heating and Air.

Duncan came up with an effective, economical solution to resolve issues with my heating and AC complications in a friendly and professional manner. I recommend these folks for all your heating and air conditioning needs.

I will use Duncan for any and all heating and cooling needs. So many other places were too expensive, gave me the run around or just didn't call back. Duncan was informative and very helpful. Their excellent customer service will keep my business and I would recommend them to friends and family. The best in Statesville hands down!

Duncan Heating and Air is by far the best HVAC company around! After my entire HVAC system went out, I called several HVAC companies to get quotes on a full system replacement. I called everyone from the "big guys" to small, mom and pop local places (I prefer to support small business) but none were as courteous, respectful , professional and as knowledgeable as Duncan.

Joe came out and spent his time (~30-40 mins) looking over every component of my system. He was very knowledgeable, straight up and honest with me, which I greatly appreciated. He didn't try to upsell me or push a "premium package" nor was he pushy at all. They were able to get me a VERY reasonable quote with a quick turnaround time that included top-notch equipment (I decided on American Standard) that was several thousand dollars cheaper than most companies.

Once the equipment was ordered and arrived, there were able to quickly work me into their very busy schedule considering I had no heat whatsoever. All around, best experience I've ever had with an HVAC company; in dealing with everyone from the front office staff, to Joe, to the service/install crew who were also extremely courteous and professional. If you're looking for the best HVAC company in town, look no further than Duncan Heating and Air, I promise you won't be let down!

My family recently had to replace our entire heating and air conditioning system, which was a huge headache, gigantic investment, and overall stressful situation. After multiple quotes and companies coming out to the house to look at the system we went with Duncan because their quote was the best and David treated us fairly, like family, and like we were important not just a customer. Would definitely recommend using these guys, although I hope no one has their heat go out like ours did!

Extremely happy with the whole process.Duncan Heating & Air Conditioning Inc installed a new furnace, air conditioner, air filter, and humidifier in my house. Price was competitive for the quality of equipment. Installation went smoothly and the furnace is working great. David and the team were total professionals. Thoroughly explained the whole system and new thermostat when they were done. Didn't leave any mess behind. Would not hesitate to recommend Duncan Heating & Air Conditioning Inc.

Had AC unit to go out at 9pm. Next morning at around 10am they were here repairing the unit. Did excellent job. Thank you Corry for a job well done. And Thank you Duncan Heating and AC for being so responsive.

We have had several heating systems installed in several different homes over the years by David and his crew. The team is very professional and all of the team members know their specific roles and all are very good at what they do. I will continue to tell everyone I know that this is the company to call for all of your heating and cooling needs.
