Ellis Air Conditioning & Heating has been operating in Dallas and the broader DFW area since 1975 — fifty years in business is a milestone few local HVAC contractors reach, and Ellis has marked it as a Carrier factory-authorized dealer with a 4.8 rating across 66 reviews. That longevity isn't just marketing; it reflects a company that has outlasted dozens of competitors across half a century of Texas summers.

Brothers Mark and Kent Ellis run the business as a family operation, a structure that's defined how they've grown. What started as a Dallas-focused contractor now covers Cedar Hill, DeSoto, Duncanville, Grand Prairie, Highland Park, University Park, Irving, Lancaster, Ennis, Glenn Heights, Midlothian, Red Oak, Waxahachie, Mansfield, Ovilla, Arlington, and Ellis County. That's a substantial service footprint, backed by the infrastructure to support 24/7 emergency response every day of the year.

The Carrier factory-authorization matters for homeowners and property managers who want to know the technician working on their system has brand-specific training. Ellis installs and services Carrier systems for both residential and commercial properties, meaning warranty work and manufacturer documentation are handled correctly.

What the reviews reveal is a company where individual technician relationships matter. Customers routinely name their specific service person — Rusty, Dickie Johnson, Critter, Sammy, Mike, Jesse — and request them for follow-up visits. One reviewer explicitly asked for Jesse after he guided her away from unnecessary services that another company had recommended, a small detail that illustrates the honesty that a multi-decade reputation is built on. Another customer noted that Rusty provided a thorough explanation before making any repairs, and a third described a challenging condensation line run handled with deliberate problem-solving.

Ellis offers financing for larger system replacements, accepts credit cards, and provides online estimates. The combination of emergency availability, factory certification, and a track record stretching back to the Nixon administration makes Ellis a reliable choice for homeowners who want a contractor that will still be around for the follow-up appointment.
