We had Ellis A/C upgrade our system in our machine shop. We struggled keeping the shop comfortable in the TX heat. Aaron and Mike came out to look at our facility and put a plan in place. They upgraded one of our existing units and added a new unit to the rear of the building. The results were night and day this summer. No issues with creating a comfortable work environment. I’d recommend Ellis A/C to anyone.

Ellis AC and Heating installed a 3-Ton Carrier Condenser last year and a heater this past fall. Jerry was very willing to work with me on pricing. Installation went very smoothly. All techs have been knowledgeable and great to work with. I definitely recommend Ellis.

Ellis Air Conditioning and Heating installed a complete new system at my home yesterday and we could not be more pleased. They were very clean and installed the new system in a very timely manner. I strongly recommend them to anyone looking for a class organization for all of their HVAC needs.

Great service! Fast and affordable, Larry did a great job getting my house cooled down quickly! I was worried because my 2 yo son was getting hot in his room during his nap but they got Larry out here within 2 hrs of me calling and he fixed the problem immediately. Will aways stay with Ellis Air, always have a great experience with them and their technicians!

My A/C went out on a Friday and called Ellis immediately. They were able to get me a new unit installed Monday morning. That is insanely fast and much appreciated in this Texas heat. They also did an amazing job at the install and keeping the area clean, I would highly recommend!

I experienced very professional and knowledgeable service from Larry at Ellis ac. From the start of my service call on a Sunday to the repair , he performed service of the highest quality. He made the entire process smooth and stress deee. It’s rare to find a service provider who prioritizes customer satisfaction, Larry delivered on every level. Thanks again!

Our A/C stopped working and after calling Ellis Air, they were able to send out a technician to evaluate the issue the next morning. They figured out what was going on right away and said we could have the issue resolved the following day. We thought about our options for too long and ended up scheduling the replacement of both our old outdoor unit and indoor unit due to the age of the equipment and them being outdated for what we would pay for and have a warranty with new equipment. It was worth it and we'll be covered if anything wears out while we own our home for the next 10 years. Thank you for taking such good care of us and for all the prompt replies and follow up!! We love our new system and are always happy to recommend the great people at Ellis.

I have used Ellis AC for 20+ years. I just got a new HVAC system from them in 2024 and I am so pleased. Justin has always been my person who checks my system out and I always ask for him. great company and treat folks good.
Mike Play List
Mike & Andrea My family with Ellis A/C & Heating awesome. The technician came diagnosed the issue and quote me a price to fix the coil leak. Then we ask about the replacement of the unit in the attic & outside. Then Ellis quoted me a price to replace the entire system in attic and the unit outside. And a schedule to come install. The Ellis team showed up and quickly replaced the system. The team were friendly and respectful. Then team cleaned up and done. I would recommend Ellis Team!

Increased Energy Efficiency

Older units often consume more energy than necessary. Today’s systems offer higher SEER ratings and energy-saving modes that significantly reduce your utility bills. Whether you’re a homeowner or a business owner, energy-efficient systems lead to lower monthly costs and a smaller carbon footprint.

Explore our HVAC maintenance services to keep your new system running efficiently after installation.

💰 Lower Repair Costs

Frequent HVAC breakdowns are a sign your system may be near the end of its life. Replacing it reduces the need for constant repair visits and gives you peace of mind with manufacturer-backed warranties and improved reliability.

For short-term fixes, we also provide residential HVAC repair services and commercial HVAC repairs with fast turnaround times.

Enhanced Indoor Air Quality

New HVAC systems use advanced air filtration to remove allergens, dust, and pollutants—crucial for homes with kids, pets, or asthma sufferers. Businesses benefit from cleaner air, which contributes to better employee health and overall well-being.

Higher Property Value

Looking to sell your home? A newly installed HVAC system is a major value booster. Buyers are more likely to make offers on homes with modern, energy-efficient systems, making it easier to sell and potentially increasing your resale value.
