What Your Neighbors Are Saying About Us

Replaced the old with the new. I got a fantastic price on the new heat pump system. The installation went really smoothly, and it is working great. I like this company.

We’ve been clients of Ellis for 20+ years at our home and office. Yesterday we woke to no heat, of course with the coldest temps of the year just 2 days away, we called Ellis.

Ellis air installed an infinity heat pump system at our home 15 years ago. Best thing we have ever done. It has preformed beautifully over the years and is still going strong thanks to Ellis Air.

Jesse came for my semi annual heating checkup. He was prompt, calling ahead to say he was on his way. He was very thorough and explained everything he did.

I highly recommend Ellis Air & Heat. Larry Hatley service Technician came out and checked the unit out. Larry is one of the most pleasant, delightful person to deal with.

Commercial Heating Systems We Work With

Commercial heating comes in many forms, and our technicians are experienced across all major system types. Whether your building uses a traditional setup or a more complex configuration, we have the knowledge to service it properly.

Rooftop units are common in commercial buildings throughout Dallas and require routine attention to perform reliably through winter temperature swings.
Packaged heating systems offer combined heating and cooling in a single unit, and we install and service these for a wide range of commercial applications.
Heat pumps provide efficient year-round climate control and are increasingly popular in the DFW area given our mild but variable winters.
Furnaces and air handlers are found in many older commercial buildings across Dallas, and our team is well-versed in both legacy systems and modern replacements.
Boiler systems and hydronic heating solutions are also within our scope for facilities that rely on radiant or hot water heat.

No matter what system your facility uses, we approach every job with the same level of care and professionalism.

Keeping Your Commercial Heating Running Year-Round

In Dallas, heating season may be shorter than in other parts of the country, but that does not make it any less critical. When a cold front pushes through North Texas, temperatures can drop quickly, and a system that has not been properly maintained may struggle to keep up. Our commercial repair and maintenance services are designed to keep your heating system performing reliably before problems arise and responding quickly when they do.

Signs your commercial heating system may need attention include:

Uneven heating across your facility, with some areas too warm and others too cold.
Unusual sounds such as banging, rattling, or squealing coming from the unit.
A noticeable spike in energy costs without a clear explanation.
The system cycling on and off more frequently than normal.
Reduced airflow through vents or registers throughout the building.

Preventive maintenance is the most cost-effective way to protect your investment. Our maintenance plans are tailored to commercial systems and include thorough inspections, filter changes, and system calibration to keep everything running efficiently. With over 50 years of experience behind us, we know what to look for before small issues become costly repairs.

Commercial Heating Installation & Upgrades

If your current system is aging, inefficient, or no longer meeting the demands of your building, it may be time to consider a replacement or upgrade. Ellis AC & Furnace Repair provides full commercial heating installation services for new construction, building renovations, and system replacements. As a Carrier Factory Authorized Dealer, we have access to high-quality equipment and the factory training to install it correctly.

Benefits of upgrading your commercial heating system include:

Lower monthly energy costs through improved system efficiency.
More consistent, comfortable temperatures across your entire facility.
Reduced repair frequency and lower long-term maintenance costs.
Better indoor air quality for employees and customers.
Access to modern controls and smart thermostats that simplify system management.

We provide clear, detailed proposals before any work begins so you know exactly what to expect. No surprises, no pressure — just straightforward guidance to help you make the right decision for your building.
