HVAC reviews in Dallas, Texas

Marcelino has been great to work with. Honest and extremely knowledgeable. Will continue using him in the future.

The service is impeccable! Marcelina is very knowledgeable and informative. I’ve been using this business for 5 years and would recommend him and his crew. Very professional business

Excellent service, on time and very courteous.

Awesome to work with. So fast. Called initially due to 2 other companies taking their time to respond to me with temps in the 100s. Said he had the part and could come out the next day. Came by, diagnosed quickly and had AC back up and running in an hour with a part that I was told had to be ordered and would take at least a week. Had them come out again a few days ago when the upstairs unit stopped cooling. At first said he could come by a few day later but once I told him there was no cool up upstairs, said he was in the area and would come in 20 minutes to diagnose it. Another bad evaporator coil (good Ol Armstrong air units, a Lennox brand). Was able to recharge it to get us some air upstairs for a couple of days until he could get the evaporator coil in and installed. Love how responsive Mr Hernandez is and quick to get the situation resolved. Went above and beyond to keep costs down. Looked into the old coil to see if it was still under warranty, which it was, so i didn’t have to pay for the part. Will definitely be using them in the future and will be passing his info along to anyone that asks. Thanks for everything Marcelino

HERNANDEZ AC & HEAT has been doing repairs and maintenance on my AC/Heating units. When I finally decided to make the large purchase of a new AC/Heating unit, my choice was easy. This company is extremely dependable and honest. They provided quality service from the beginning to the end of the project. I researched and used other companies on my other properties, but this company provides security. Marcelino, is the best and I will only use this company for any future HVAC needs!

Thank you, Mark! Came out at 6:30 on Friday and refilled my unit with Freon so I wouldn’t have to spend the weekend without ac! Great guy, I’d use them again in a heartbeat!

Fair pricing, fast scheduling, and professional service for my AC replacement. Will recommend Cactus in the future

This is the BEST HVAC repair and installation company we've ever hired. Marcelino and his crews are responsive, on-time, professional and very curteous. They work very hard and produce high-quality results for a fraction of the cost of other HVAC companies. We've hired them four times now: HVAC repair, complete ductwork system replacement, insulation (spray in attic) and complete HVAC system replacement. If you want the best, use this company.

Mr. Hernandez was very kind to come out to help rescue an elderly lady from the heat on Father’s Day!!!! Your services are very much appreciated.
Mr. Marcelino is the BEST! Highly recommended!!

Hernandez AC and Heat did more than expected. Professional, Timely and the crew was polite and cleaned up afterwards. If you are in need of a furnace/AC please consider this company.

I was referred to Marcelino by a colleague of mine because of an AC issue I had, he was able to be there that same day within 2 hours and find the issue! He’s extremely professional and knowledgeable in his craft, I cannot recommend him enough to the point that I’ve told all my other colleagues about him because he’s that good 👍🏼

Mark came out on a Sunday for an emergency service during the heatwave. Was prompt, professional and helpful. I am so appreciative and would recommend his services to anyone looking for a honest & reliable a/c company.

I really like that Hernandez AC & Heat provided me w/an window of availability, then texted me when Mark was on his way. Mark arrived ON TIME, was courteous and kept his work area neat and organized. Mark cleaned up after himself and fixed my a/c promptly. I like that he explained what the issue was, how he would remedy it and was very thorough in his inspection of my a/c. I look forward to working with this company for all my cooling/heating needs.

I have been using Hernandez AC and HEAT for several years now and have nothing but positive things to say about them. I couldn’t be happier with the work they did with installing my new A/C system - I recommend them to everyone I know.

Truly outstanding and professional service. I couldn’t be more pleased with the job the crew from Hernandez AC and Heating did. They moved our AC unit to a new location and fixed several issues from the previous company we worked with. Very up front about the needed work and clear about pricing. Super professional from start to finish. I highly recommend them.

I love this company! Marc is so kind and very knowledgeable and I had a quote emailed to me within 3 hours of the consultation.

My system was over 20 years old and Marc guaranteed me that the new system and returns would help make my life much more comfortable.

I got all new duct work, A/C and heater and they sucked out the old insulation and blew in new insulation.

The crew was very polite and hard working and they cleaned up after themselves. They should be done tomorrow so I don't have final pictures yet but I'm already a customer for life!

My mom will need a new unit in the next few years so I'll for sure send the business to Marc and his team.

Thank you for everything!

Highest recommendation for Hernandez AC & Heat! Last month they helped repair a mystery issue we were having with our furnace fan not turning on. They recommended only one part that needed to be replaced and that fixed it! We have an old furnace and AC but they have only ever suggested the repairs that are really needed. They take the time to diagnose, really know their stuff and have kept our older unit working wonderfully. Because of their top notch work we also had them install a mini split this month and they went above and beyond. I’m so glad I found them!

Marcelino and his crew (Juan & Cesar) did a full system installation including replacing all air ducts to my HVAC system.

One word to describe my experience: Phenomenal! From beginning to end. Their responsiveness, their communicativeness, their willingness to explain and answer questions and most importantly their QUALITY OF WORK. I am an extremely particular person and its very hard for anyone to meet my expectations. Marcelino didn’t just meet them, he exceeded them.

I definitely recommend Hernandez AC and Heat to anyone looking for HVAC services.

Marcelino explained everything in detail and followed up with me to ensure everything was to my liking. His crew was also very professional and they did an awesome job with the installation of the new ductwork and clean up. Would definitely recommend!

Hernandez AC and heating business is a very good business. Marcelino is a top rate person to work with his assistant is also a top rate person to work with. They did a great job very efficient, very quick, and reasonable prices.
He works with you on any problems you have. He explains everything to you. I think this is just a great company.I highly recommend them. I will be using them again. Thanks guy's.

I had a good experience with this company before and after the installation of my new AC unit. Purchase and guarantee was explained well. The technicians are very knowledgeable and responsible. If you have a difficulty with your unit they come fast and fixed. I highly recommend them.
