HVAC reviews in Denton, Texas

Jacob Morris performed our winter service system maintenance and we are very pleased with his knowledge, thoroughness, and politeness. He is a professional and we will request him in the future. Thanks for the good service!

They did awesome. Albert Carillo came by and checked our ac system. Saw that the fuse needed to be replaced got shocked but still went through the work.. He got it done to get us ready for the coming cold weekend

The tech, Norbert Rodriguez, was thorough and friendly. Never fun to get expensive quotes on full replacement of HVAC, but he gave us a lower cost option to try and keep the old system running a little longer. Cleaned up everything and vaccuumed the floor. Good service.

Super fast and prompt service. Booked on line and a fantastic technician named Cody was out the next day. He was thorough, polite, helpful and went above and beyond to help me out not only with my AC but also with a minor plumbing issue. Would definitely recommend.

Toby Hernandez was amazing, he was very thorough, he was extremely knowledgeable with HVAC and had answers and suggestions to all my questions. By far the best mechanic that has ever been out here. I would have to give Toby an A+++, and I have requested him for all my future work here.

So about a week ago our AC stopped working. My wife was sick and needed the ac! Very next day Jacob showed up. Great guy. Knew what he was doing.

10/14/25. Dylan Tekell came out to do our fall service. Great guy. Was great service.

12-3-25. Once again Jacob to the rescue. This time new ductwork. Besides being a complete pro at his work Jacob is a great guy.

Y’all can’t go wrong with Cote’s Mechanical!

If you need your AC fixed they are great!

Albert came today and fixed our HVAC problem quickly and efficiently. Albert knew what to do and was courteous and friendly, and a pleasure to deal with. I will continue to recommend Coates, and can say that every employee I've dealt with, including Albert, have bee great to work with.

Anthony Montez A#1 Air showed up on time with excellent customer service. Extremely friendly. He was the first of 5 AC and heating professionals that we had come out that took the time to go in attic to check for leaks and rodent damage. Apparently the furnace was programmed wrong and would only blow cold air. All of this in less than an hour. Great job Anthony. My wife and I are very grateful!!

Amazing company. Friendly techs come same day even weekends. Not pushy. Fixed my old system. Later installed a new system. Moved it into the attic with all new ductwork. House cools better and my allergies improved. Plus it's a family business. Thank y'all so much 💓

I had my A/C go out they were able to get someone out the next day to take a look. They called and told me they had someone call out so they reached out to a sister company to give us the bid. Manny gave us the bid and he stayed in contact answering any questions I had about the system, what was in the estimate, etc. Tony Palacios and Jose Cardoza are the techs that came to install, they made sure they worked clean, they had drops throughout the house where they would work, and made sure to capture the dust from the new return they had to cut in. I asked if they would let me know when they removed the old outside unit so I could remove a small tree and they took care of it for me. Everyone we worked with was incredibly knowledgeable, professional, and kind. The system itself is amazing!

Excellent service! I highly recommend Cote’s for installation, yearly service and inspection on existing units. Especially important when a buyer is looking to buy an existing home. As a previous Realtor and Home Warranty rep, I told buyers to have the HVAC units inspected by a licensed HVAC company during the inspection period. It served as a way to show a unit was in good working condition at the time of inspection for the future proof to a home warranty company and if there were any prior issues to the seller for negotiation of repair or replacement.
I’m enjoying my new unit that Cotes installed and having it checked and serviced twice a year.
Andy was my technician this time and I highly recommend him for the Montague County area.

I had a great experience with Cotes for HVAC Replacement. The tech they sent out, Houston, came by when we were having problems with our current unit and encouraged us to replace our 14 year-old system. He was very knowledgeable and professional, so we ultimately went with Cotes over other quotes we had received. It did take awhile to get the city by to inspect the unit after install, but the answering service was very helpful in getting everything scheduled. Cotes did have to come back out to replace a cap the city flagged. This repair was handled by Cade who not only fixed everything quickly and professionally, but also flagged a plumbing issue that was missed by the city and the installation crew. Great techs like Houston in Cade are really what make you trust and want to work with a company again. I really felt like both of those gentlemen wanted the best for my family and I!

Jesus with Cote's was great today for our first maintenance check after installation. Very thorough, knowledgeable and listened to everything we said. Great experience with Cote's from the start!

I noticed my heater wouldn’t come on when it got cold in the house. I called Cite’s and they got out that day. We had to order a part to fix the issue and the next day they returned to put in the new part. Jacob Morris was my technician and was very courteous and prompt. Thank you so much for caring about my comfort and getting me some heat as quickly as you could.

Service provided in Flower Mound, TX.

I highly recommend Cote's for HVAC needs. I have used them for over 10 years, and have always been happy with the service provided. The best thing about Cote's is that they are accommodating by sending a dedicated technician every visit ( originally it was Robert, then Houston and now Albert C.). This builds a good rapport and gives me consistently stellar service which I truly appreciate! The company was taken over by a larger firm, and I feared that I'd loose that personal touch, but Albert (who came from the other firm) was just as friendly, honest, informative and helpful as my previous Cote's technicians!

Call and try Cote's for your HVAC issues - you won't be disappointed!

Do not call Cote’s. The reviews are for the OLD COMPANY. The owner (Cote) sold the company and it’s not the same service anymore. Imagine going from a personal relationship with the technicians to now a 3rd party answering system asking you the same questions over and over again (how many units do you own, do you have a maintenance plan with us, what’s the age and model # of each unit, what’s your warranty expiration date, etc) — as if we didn’t spend $40-50K with them on new units.

Worst of all, the communication from the main office to the dispatch team is absolutely awful. The office will tell you they’ll give you a call back — crickets. You have to reach out to them and almost beg them to work. We pay for an annual maintenance plan and I’ve had 3 technicians come out now and my filters are still not changed. One will say, “I don’t have the filters.” The other will say, “I was just told to do the inspection, not change filters today. I’ll have the office call you to schedule.” The next guy will say, “I’m ready to change your filter. Oh, I was supposed to bring them? Ok, let’s reschedule.”

It pains me to write this review, because their technicians are/were actually very knowledgeable and I was hoping for a 10 yr relationship with this company - they installed our brand new units. But this is not a family owned business anymore. A lot of the good technicians we knew already left. I wouldn’t be surprised if a private equity company owns this firm and is consolidating with other local HVAC companies trying to do more with less — and ultimately the customers will pay for it.

I have been a customer of Cote's for 25 years. Service and reliability have deteriorated. I have been trying to have an issue resolved since late November. Calls not returned...secretive about speaking with supervisors. Used to be a well run company. I have moved on to another outfit. I would not recommend.

Had my garbage disposal replaced and the experience was smooth from start to finish. The technician arrived on time, explained the issue clearly, and completed the replacement quickly and neatly. Everything works perfectly now and the area was left clean. Very satisfied with the service and would definitely recommend.

Albert and Julio did a great job in identifying the problem with my hvac unit and provided a solid fix. These guys worked diligently and had a great attitude throughout the process. Cotes mechanical stands by their warranty with professional technicians.

Daniel the technician is great! He always does great work. In fact outstanding!

The 2 stars is that the communication with the management on issues is almost nonexistent. It’s like you call the call center they pass the information on and no one ever follows up.

So the technicians I have had were all great. That’s not where the problem is.

After 11 years of loyalty, I’m leaving. Since their merger with A#1 Air, quality has plummeted. I was told by a tech $6,500 for a repair that another company fixed for $150. Get a second opinion!

UPDATE:
Since my initial post, the management at Cote's Mechanical reached out to me directly to hear my concerns. I felt that my frustrations were truly taken to heart and they seem committed to making things right. We have scheduled an appointment for a technician to perform a thorough diagnostic of my entire system to address any outstanding issues. I appreciate the proactive communication and will provide a final update once the service is complete.
