Dunn Plumbing, Heating and Air Conditioning / Dunn One Hour Heating and Air Conditioning

I’m not going to get into specifics, but Brett and his team just helped someone today with a broken furnace who needed help and I will be ever grateful for their kindness and charitable service. I will recommend no other company or use anyone else for my own service! A+A+A+

Dunn rep. came out to review my issue, stated for about 10 min and charged me $50 for the device call, but it took them 3+ weeks to call me back for an estimate and the cost to replace the gasket was extremely high compared to other estamates I received. I wasn't so upset about the cost it was more so that it took almost a month to respond.

I called early in the morning and explained my emergency (house temp was 33F). They got a technician out within an hour, who was able to get the furnace running quickly. The technician explained the problem in great detail and told me how I could try to resolve it myself in the future. We had called another company the night before who had attempted to scam us. I honestly was ready to buy a new system but he told me that it wasn't critical yet. I would definitely hire Dunn again - great experience.

Wow, I can't say enough about how grateful I am that I called this service provider. Imagine smelling an electrical burning smell in your house the day after Christmas at 8:30 p.m., and suddenly noticing that, while the temperature outside was a frigid 8 degrees, and the thermostat set to 72, you notice it starts feeling cold, and realize the temperature inside has dropped to 69 degrees. Panic sets in. Panic because it's getting colder, It's after 8 p.m., and it's the day after a Holiday. Don't fret, call Dunn Heating and Cooling, they're available 24 X 7. They sent a technician out within an hour, and he assessed the situation, the Blower motor on my 5 year old Frigidaire Furnace was burned up. There was nothing he could do that night, but did note the model and serial number of the unit, and promised to contact Frigidaire regarding warranty (10 year warranty on parts). The next day, the folks at Dunn contacted me, and let me know they'd contacted Frigidaire, and Frigidaire had authorized the warranty, so there would be no charge for the new motor. They sent a professional, pleasant technician out who promptly removed the old blower motor, demonstrated to me the damage to the shaft (bearings were shot), and then put a brand new one in. Within an hour, the house was back up to 72, and we were comfortable once again. I'm really impressed with several things regarding this provider, that are lacking in other providers. First, 24 X 7 service is unbeatable, even if it involves overtime charges. 2nd, the communication on Dunns part, keeping us informed at every step, what and when everything would happen, and 3rd, actually contacting the manufacturer for me and authorizing a replacement part was above and beyond my expectations. I thought I'd be paying $500 for the motor, and arguing with the manufacturer over how much they would reimburse me. This was a stellar experience, and Dunn Heating and Cooling is now my go to provider for HVAC Service in the future.

We chose JT Dunn based on a friend's recommendation after contacting 4 reputable HVAC companies in STL. They were a bit pricey with their initial bid but were willing to negotiate. We were really happy with the work they did. Brett (owner) came out initially and he was professional and very knowledgeable and did not use any high pressure sales tactics. His crew then also showed up on time, and did the install very professionally and in a timely fashion and cleaned up well after they were finished. We would recommend JT Dunn anytime.

Great. A serviceman was there the same day we called. Did the repairs quickly.

Great, from the estimate (done remotely cia pictures), to the work they were very good and quick!!

Everything was fine but they overfilled and had to come back while I was out of the country.

Not great. They had to come back because the unit wasn't cooling. They had added too much coolant and had to let some out. They also took three attempts and almost a week in 100 degree weather to figure out the problem because of logistical issues at my house (handler in attic and small entry). But they were very nice about the whole thing.

Fine, it just took a long time and sometimes hard to get a response from them.

Great. Everything was installed as promised.

Contacted Dunn and we missed each other several times. Once I finally spoke with someone, I explained what I needed done at the home and knew I would want a more efficient unit upon replacement of the existing unit. I took pics for him and was told they would get back with me with a game plan. I did tell him no rush because it was hot and I wasn't using the heater anyway. Eight days later, I still had not heard anything from them. I began to get a little concerned and at least expected a call about the game plan by then. I figured the replacement t could still wait. I finally cancelled and I'm still waiting on my refund with no answer from Dunn after making several calls. I'm now asking Angie's list to step in months later.

Rob the technician was very punctual. He called when he was on his way. He was wearing a clearly marked Dunn HVAC shirt with his name on it and was clean and professional. He serviced my A/C and was on his way without a mess. I would recommend Dunn HVAC and Rob to anyone that needs HVAC service.

Timely, well priced and quality work.

Everything has run perfectly in the two years since the installation.

Job went very well, everything was outstanding, i will have them replace the ac if price is right .

Great! On time, professional, friendly, answered all my questions. Was very thorough and explained what he had done.

Great price on a great product... Angie's List website was acting a little "buggy," said the deal had expired, before the date it was scheduled to expire. Called them directly, said they would be happy to honor the deal, punctual and professional installation two days later!

Great! All fixed, even though he had to work on a hot night in the dark.

Dunn Heating and Cooling has completed a number of projects for us. They are always timely and professional. I recently asked them to complete some work in our basement, and it is better than I ever would have ever expected! We will always use Dunn Heating and Cooling! They literally are the best.

Hiring Dunn Heating & Air Conditioning was just a mediocre experience. When I first called to schedule an appointment, their office staff was helpful. For the planned job, they thought the job would be around $400-$500. As we got into the job, scheduling and communication was difficult. The job ended up being bigger than they thought (at no fault of their own). When our technician couldn't get everything done in one day, he said the office would call the next day to schedule. I never received a call and I had to call them to reschedule, come to find out they couldn't get us in until the next week. There were a couple more times where I had to call them asking when to expect the technician. It was just a very dragged out experience. After everything was said and done, our total was over $1,500, and that was after a discount that they generously gave us. Our technician was friendly and sympathetic with our situation, which we appreciated. I understand that the project ending up being bigger than anticipated (there were more gas leaks than we thought); however, for the other two repairs it was $750 and I feel that should have been within the $400-$500 original quote. Laclede was also unhappy with how secure the new gas piping was. There were many spots where it was hanging from the basement ceiling. My dad came and secured that himself.

Fantastic. Rob was an excellent service provider--very knowledgeable, quick, considerate, and personable. I'd highly recommend Dunn based on Rob's service and quality. Also, the team answering the phones and assessing the situation was helpful. Overall, great experience!

I purchased the coupon off Angies list for $435.68 for Whole House Humidifier + Furnace Tune-Up + Carbon Monoxide Safety Check. They were on time, professional and clean. I have now been using the the humidifier for over a year. It works great during the dry winters and is easy to adjust. The gentleman who did the work also took the time to show me how to change the filter on the humidifier. They were great, and I will use them again.

gave suggestions for improvements to my unit and did extra items

Very good - technician was on time and did a great job.
