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 HVAC Equipment We Install

We install a full range of commercial HVAC equipment sized and configured to meet the demands of your building and business type. Every installation begins with a thorough assessment of your space, load requirements, and operational needs so the right system goes in the first time.

Equipment we commonly install includes:

Rooftop units (RTUs) are one of the most practical solutions for commercial buildings, keeping equipment off the floor and out of the way while delivering efficient, centralized heating and cooling.
Split systems offer flexible configurations for smaller commercial spaces or buildings where ductwork routing requires a more custom approach.
Variable refrigerant flow (VRF) systems provide precise zone control and energy efficiency, making them well-suited for multi-zone commercial environments.
Commercial heat pumps deliver both heating and cooling from a single system, offering a cost-effective option for buildings in climates where extreme cold is less of a concern.
Packaged systems consolidate all components into one unit, simplifying installation and maintenance for certain building types.

As a Carrier Factory Authorized Dealer, we install equipment built to perform. Our technicians are factory-trained and stay current on the systems we sell, so you can count on a quality installation backed by real expertise.

How Our Commercial Installation Process Works

A commercial HVAC installation is a significant investment, and we treat it that way. Our process is designed to keep you informed, minimize disruption to your operations, and deliver a finished result that performs the way it should.

We start with a detailed site assessment and load calculation to determine what your building actually requires. From there, we put together a clear proposal that outlines the recommended equipment, scope of work, and pricing with no hidden figures. Once you approve the plan, our team coordinates scheduling around your business needs and arrives fully equipped to complete the job efficiently. After installation, we test and commission the system to confirm everything is operating correctly before we consider the job done. We also walk you through the system so your team knows what to expect and how to get the most out of it.

New Construction and System Replacement

Ellis AC & Furnace Repair works with both builders on new construction projects and business owners replacing existing systems. Each situation calls for a different approach, and we have the experience to handle both well.

For new construction, early collaboration matters. We work alongside contractors and project managers to plan HVAC systems that integrate cleanly into the building design, meet code requirements, and align with the project timeline. Our familiarity with the Dallas market and local regulations makes coordination straightforward.

For system replacements, we evaluate your existing setup honestly. If your current equipment can be salvaged or upgraded, we will tell you. If replacement is the better long-term decision, we will explain why and give you the information you need to make a confident choice. Dallas businesses deal with prolonged cooling seasons that put heavy demand on commercial systems, and our team understands what local conditions require when recommending replacement equipment.

Why Dallas Businesses Trust Ellis AC & Furnace Repair

Our technicians average more than 10 years of tenure with the company, which means the person on your job site is not learning on your dime.
We are a Carrier Factory Authorized Dealer, NATE-certified, BBB A+ rated, and licensed through the TDLR (Texas License #TACLB002064).
We provide free estimates and clear proposals so you know exactly what you are agreeing to before any work begins.
Our service fleet is large and fully stocked, which means we can move quickly and complete jobs without unnecessary delays waiting on parts.
We are family-owned and have never sold out to a corporate chain, so the values that built this company are still the ones guiding every job we take.

Dallas summers are long, humid, and demanding on commercial HVAC equipment. High humidity levels make it harder for systems to maintain comfortable conditions and put added strain on components over time. Having an experienced local team that understands how the climate here affects commercial systems is a real advantage when it comes to choosing the right equipment and installation approach.
