HVAC reviews in Flower Mound, Texas

★★★★★
 Calvin Climate deserves every star! Over 10 years, they’ve consistently delivered exceptional service, from routine maintenance to full AC installations. They replaced two outdated units in our home (one 1.5 years ago, another this year) with Calvin personally explaining everything in detail. Their staff is punctual, polite, and never pushes unnecessary services. Joining their family plan was a great decision. When our AC failed, Calvin ensured we had portable units for our bedrooms the same day, a lifesaver in Texas heat. Unlike many corporate-owned HVAC companies, Calvin’s personal ownership shines through in their honest, high-quality work. Highly recommend!

I recently had an HVAC system installed by Calvin’s Climate, and overall, I’m very satisfied with the experience. The staff and technicians were professional, courteous, and clearly knowledgeable. Their pricing was reasonable, and they provided a quick and accurate diagnosis along with solid recommendations.

There were a couple of small issues after the installation — the thermostat needed calibration and there was a problem with the drain line — but I really appreciated how quickly and efficiently the team responded. Both problems were resolved promptly, which shows their dedication to customer service and follow-through.

I highly recommend Calvin’s Climate for anyone in need of HVAC services. Great service, fair prices, and a team that stands behind their work.

Very impressed with the services received by Calvin’s! Tom the A/C guy was amazing very informative and explained everything, the maintenance he performed on my A/C in April saved us over $100 a month this summer on our bill. The heater technician also was very helpful and informative , can’t wait to see how great our bill does continuing through the winter months! I highly recommend Calvin’s, customer service is excellent from the office to the techs! Best decision I could’ve made buying their maintenance package! Also, unbeknownst to me I also have another 3rd maintenance service in April 2026. It is definitely money well spent!

Calvin's Climate did a great job replacing my old air conditioner & heater. Calvin's recommendations for my new unit were right on point. The installation team was very professional and knowledgeable. They were on time and clean upped when they were finished. And all for a fair price! I highly recommend them!

Patrick was so personal and professional with his service . Very knowledgeable and outstanding communication skills . Would highly recommend him for all your HVAC needs

I love the attention and service we receive from Calvin’s Climate! Gary has always been very thorough and we’re very grateful to have found this company for our HVAC needs.

The technician was very profesional and knowledgeable, however there was a poor quality job done (see pictures after job was completed)I ended up cleaning that out by myself. They quoted me an evaporator coil replacement however the competition offered me a better option. Same brand as my equipment (carrier) because Calvin didn’t include me the dripping panel if I decided to choose the Carrier evaporator so ended up canceling with Calvin’s. Unfortunately I paid their membership plan hopefully I have a better experience for the next year.

So happy with Calvin’s Climate. They came out promptly and were able to fix my unit without replacing it. Would recommend them to everyone. Their honesty and expertise was second to none

Great service. I appreciate communication from the tech and attention to detail. I feel like he has my best interests at heart, and it isn’t just a matter of checking off boxes. Thank you!

We had one of our AC/heating units replaced by Calvin and his team. Calvin is so precise. He took measurements, calculated room volume, figured out the right sizing of unit, explained my options, and helped us make the right choice for a replacement. The team was prompt, polite, and professional. they finished the job in one full day, and everything is working great!! Thank you Calvin and team!!!

I am a first-time customer of Calvins Climate and heating. Have used several other large HVAC companies and thought I would try a local one in flower mound. The experience was excellent! Patrick was my technician and did a fantastic job of diagnosing the problem and resolving it with no additional cost once he found that it was just a loose connection. Anyone that lives in the flower mound area or surrounding, should really give Calvins Climate the opportunity to earn your business.

Wonderful experience!
My AC stopped working On Saturday and they were at my house first thing when I requested on Monday and walked me through everything that was wrong and showed me physical proof and got me in for a very, very reasonable price!

My service tech Reese was very informative and very nice to talk with. I will definitely be using calvins again!

Reese, Favian, Bryan, and Nathan were all great to work with! They were very polite and took their job seriously. My husband and I highly recommend Calvin’s Climate! Kathy Howe-Grover

We truly loved worked with Calvin climate. They were very professional, very transparent on their prices, thorough with their inspection and quotes and did excellent work in a very reasonable time frame. We are very impressed with their presentation and their quality of work. We would definitely recommend them to anyone! And they also gave us cute cookies as a "Thank you" for using them to repair our entire hvac system. We needed a full take out and install of hvac and duct work and it all works amazing and super efficient now!
