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 Cooling Systems We Install & Maintain

We work with a wide range of commercial cooling systems and can recommend the right solution based on your building size, layout, and usage demands. As a Carrier Factory Authorized Dealer, we install and service equipment built to meet the specific challenges of the Dallas climate, where summers push systems hard for months at a time. Commercial systems we install and maintain include the following.

Packaged rooftop units (RTUs) for retail, office, and light commercial buildings
Split system commercial air conditioners for flexible zoning and efficiency
Variable refrigerant flow (VRF) systems for buildings with diverse temperature needs
Ductless mini-split systems for server rooms, additions, or supplemental cooling
Commercial heat pumps for year-round heating and cooling efficiency

No matter the system type, our technicians are factory trained and follow manufacturer standards to ensure reliable performance and long equipment life.

Scheduled Maintenance & Commercial AC Repairs

Unplanned breakdowns are expensive and disruptive. Regular maintenance is the most effective way to protect your investment and avoid downtime during peak cooling season. Ellis AC & Furnace Repair offers scheduled maintenance agreements designed for commercial properties, with service visits that keep your system running efficiently and help catch small issues before they become costly repairs.

When repairs are needed, common issues we address include the following.

Refrigerant leaks and recharging
Compressor and condenser failures
Thermostat and controls malfunctions
Evaporator coil freezing or damage
Electrical component failures and wiring issues
Airflow problems caused by dirty filters or blocked ductwork

Dallas humidity adds additional strain on commercial cooling equipment throughout the spring and fall seasons. Moisture-related issues, including mold growth in ductwork and coil corrosion, are common in this region and are part of what our technicians inspect during every service visit.

Commercial AC Installation & System Upgrades

Older commercial systems that are struggling to keep up with demand cost more to operate and are more likely to fail at critical moments. If your equipment is aging, undersized, or no longer meeting your building’s needs, Ellis AC & Furnace Repair can guide you through a straightforward replacement or upgrade process. We provide free estimates and clear proposals so you know exactly what to expect before any work begins.

Our installation process includes the following.

A thorough assessment of your current system and building requirements
Honest equipment recommendations based on performance, efficiency, and budget
Professional installation by experienced, certified technicians
System testing and verification before we leave the job
Guidance on available efficiency upgrades and rebate opportunities

Upgrading to a higher-efficiency system can meaningfully reduce energy costs in a climate like Dallas, where commercial cooling runs heavily from April through October.

After-Hours Emergency Commercial AC Service

A commercial AC failure does not follow business hours, and we understand that cooling loss can mean lost revenue, product spoilage, or the need to close your doors. Ellis AC & Furnace Repair offers 24/7 emergency commercial AC service throughout Dallas and the surrounding area. Our large fleet of service vehicles and well-stocked trucks allow our technicians to respond quickly and complete most repairs in a single visit.

If your commercial system goes down, call us. We will send an experienced technician, give you an honest assessment, and get your system back online as fast as possible.

Frequently Asked Questions

How often should commercial AC systems in Dallas be serviced?

Most commercial systems benefit from at least two maintenance visits per year, ideally in spring before cooling season and again in fall. Dallas heat and humidity put heavy demands on commercial equipment, making regular service especially important in this region.

How do I know if my commercial AC system needs to be replaced rather than repaired?

If your system is more than 15 years old, requires frequent repairs, or is no longer keeping your space comfortable, replacement is often the more cost-effective choice. We provide honest assessments and will never recommend replacement if repair is the right call.

What size commercial AC system does my building need?

Proper sizing depends on your building’s square footage, ceiling height, insulation, occupancy, and other factors. Our technicians perform a full load calculation to recommend the right system for your specific space.

Does Ellis AC & Furnace Repair service all commercial system brands?

Yes. While we are a Carrier Factory Authorized Dealer, our technicians are trained to service and repair most major commercial AC brands. We will work with your existing equipment whenever possible.

How quickly can Ellis respond to a commercial AC emergency in Dallas?

We offer 24/7 emergency service and maintain a large fleet of service vehicles to respond as quickly as possible. In most cases, we can have a technician on-site the same day you call.
