Stay away from this business for plumbing issues. Highway robbery. I literally had a similar job done by them a few years back for $245 so naturally when I needed this again I called a few days ago and they charged me $625 for same job with an additional shower leak(minor) and their tech took hours to complete and has to have another come bring parts and assist then as leaving toilet still not right and had to come waste more time to fix and blamed it on a cracked overflow pipe. I call bs on that as I had replace all that hardware before them coming out. To make matters worse when my wife called to get explanation for charges they did not provide and claimed their system doesn’t do that. I called today and advised they would have to get info and call me back. Literally hours later I get a call back stating they should have charged me more for all they did. I call bs on this too and advised them that I will never use them again. They should be embarrassed to say they do plumbing work. Hell avoid at all cost. Find an uncle or use another plumber. Smdh

I was referred to Duncan Heating and Air from the Carrier warranty representative. The associate took my information, called me back within 10 minutes, and dispatched an A/C tech to visit my home between 2PM and 2:30PM. Steven showed up precisely at 2:00PM. Steven was friendly, knowledgeable, efficient, and honest. His expertise with Carrier A/C systems is extensive, and he was able to explain every issue with my HVAC unit in layman's terms. He also provided multiple, accessible options based on his diagnosis. I am blessed that he was my A/C service man today. I cannot recommend him highly enough.

Called on Sunday morning at 8:00 am during an extreme winter event. Got a return phone call from Barbara within 5 minutes. She dispatched Steven and he was here within an hour. Steven did a great job explaining the issue and got us fixed up as quickly as possible. We have done business with Duncan for almost 10 years and appreciate their professionalism. Steven and Barbara just reinforced our opinion. Thank you Duncan for your great service.

ATMOS told me I had a gas leak, so they locked out my gas; no hot water. Duncan Heating & A/C came out almost immediately. It took about three days to find and repair the leak. Casey did a fantastic job! I really enjoyed interacting with him throughout the process. He made sure that I understood what he was doing, and he repaired everything much better than it was previously. I've already recommended Duncan Heating & A/C to my colleagues at work.

I was having an ongoing issue with my ac unit and the 1st company I reached out to couldn’t fix it after 2 visits. Today I called Duncan. I explained the issue and within 10 minutes the problem was found and my ac unit is working the way it should again. I’m a very satisfied customer.

Our air conditioner went out and they were so prompt at getting a technician here within 2 hours of our calling them. We had to get a new unit and they kept us informed about shipping and when it got here they installed it the next morning. We have used Duncan for 30 years and they are a great group of folks.

Duncan Heating and Air has been a true lifesaver for us amidst the scorching heat wave in West Texas. Their prices were incredibly reasonable, and their communication was top-notch. They swiftly addressed the necessary repairs without pushing any unnecessary add-ons on us. Their focus was solely on fixing what needed to be fixed, and they did so efficiently.

They called at 1:00pm, said they were on their way, and AC was up and running by 1:45. Someone else had already come out to work on it before and charged me 385, and didnt fix the problem. Very reasonable and fast. They're in my book as first ones to call. Thank you so much.

I rarely do reviews at all. But Considering how this company saved my Family today I felt the need to do as such. I called, and im not exaggerating, over 20 companies on my Friday Morning when I Noticed my AC was out and blowing Hot air. I got blown over by every one of them telling me they can get to me maybe on Monday. Its 109 Degrees outside and you want me to wait for the weekend? On and On it went, until we Came across Duncan and they Said they would take care of us. I Kid you not 10 Minutes later they called me letting me know a tech had finished early and was on his Way. Very professional shows up and takes care of business. I got my AC back on Cooling down the house within 10 minutes of that. I could not recommend this Company more then I do. They will be getting all of my business that I can possibly give them. Don't waste your time with other Companies. They obviously didn't want my Business. Thank you Bridgette for helping my Family today.

We called after midnight on Friday night. The person answering the phone took down the details and said a tech would be out in the morning. At about 6:45am I received a call verifying that we still wanted service. I told them that we did. The tech arrived at about 7:25am. Steven knows his stuff - down to what year the outside air conditioning unit was installed. He diagnosed the problem, changed out the part, added a little coolant, did the paperwork and was done by 7:45am. It wasn’t what I would call “cheap” - but I do think I paid a fair price for service that quick and competent. It’s now 8:15am and my house is back to its normal temperature.

Saturday night we called Duncan about 8pm. The temp outside was 101 degrees. Our A/C quit working completely. By 9:30 pm, the technician had the system up and running like new. Unbelievable customer service. Thanks again. B Brunson

My A/C went out last night. I called Duncan early and got their service. A technician called me back quickly. The technician, Steve, was professional, courteous efficient and quick. I feel they changed a fair price for the new motor and labor. I will definitely use them in the future!

This dynamic duo we will in furture services request by name. Dustin is upfront about whats needed, suggested and necessary. Price quotes are VERY reasonable and better than competitors. I'm grateful I was given a referral from another heating/ac representative who was unable to assist. Definitely this home is now a Duncan services home. Thanks again Dustin and Braxton y'all saved our day. Thanks, Duncan Heating and Air Conditioning for hiring and retaining such knowledgeable employees.

We called Duncan because we had a plumbing issue with our toilet, bathtub, and washer. Justin showed up quickly and was very professional. He explained all the issues that caused the clogged pipe and fixed it quickly. He was very thorough and I would definitely call him again if we have any other plumbing or AC issues.

I accidentally ran over the Freon pressurized pipe for the ac with my lawn mower. On a Sunday of course. I was so upset, calling everywhere I could to get quotes. Every place I called, and it was a ton of places available 24/7, quoted me at at least $1600 and said it would take hours to replace and they couldn’t get to it same day. Called Duncan, they were here within the hour, fixed it within an hour and charged me $561. They are amazing! Will forever use this company!!!! So kind, helpful, fast, trustworthy, and they don’t take advantage of you and price gouge. Thank you, Duncan!!!!

They were very prompt in getting to my leak in my foundation of my home. They traced and found the leak in my cement slab. The repair men were very conscientious about minimalizing mess and destruction when breaking through the cement to get to the leak. They took steps to avoid damage to baseboards and sheet rock even though those barriers made the repair more challenging. They cleaned up any mess/dirt afterwards. They were very knowledgeable and patient when I asked quite a few questions. They did a great job!! I would highly recommend Duncan Heating and Air Conditioning Inc. and Plumbing.
