Air Conditioning Repair in Dallas, TX

Contact Us

Dallas summers push air conditioning systems to their limit, and when the heat index climbs past 100 degrees, a struggling AC unit can turn a home into an uncomfortable place fast. Ellis AC & Furnace Repair has been helping Dallas homeowners stay cool since 1975, with technicians who understand exactly how this city’s climate and housing stock affect cooling systems. Whether your unit is blowing warm air or has stopped working altogether, our team is ready to diagnose the issue and restore your home to a comfortable temperature.

Dallas is a large and varied city, with everything from newer builds in the northern suburbs to older homes closer to downtown and along the Trinity River corridor. That variety means no two AC repairs look exactly alike. A technician working on a newer system in a modern subdivision may be dealing with a different set of issues than one working on an older unit in a neighborhood built decades ago. Our team has spent years working across these different pockets of Dallas, so we bring that local knowledge to every job.

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.

Signs Your AC Needs Repair

Catching AC problems early can save you from a full system breakdown during the hottest part of the year. Here are some of the most common warning signs homeowners in Dallas should watch for.

Warm air from vents
Weak or reduced airflow
Unusual banging or squealing
Frequent cycling on and off
Rising energy bills
Water is pooling near the unit
Musty or burning smells
Warm spots in certain rooms

If you notice any of these issues, it is best to have a technician take a look before the problem gets worse. Small issues like a clogged filter or low refrigerant can often be resolved quickly, but ignoring them can lead to more expensive repairs down the road. In a city like Dallas, where triple-digit temperatures can stretch on for weeks at a time, a delayed repair often means a system has to work even harder to keep up, shortening its overall lifespan.

What's Causing Your AC Trouble

Dallas homes face a unique combination of stressors that can wear down an air conditioning system faster than in other parts of the country. Long stretches of high heat force compressors and condensers to run for extended periods, accelerating wear on components such as capacitors and fan motors. Add in the region’s humidity, especially during late summer, and coils can develop moisture-related issues that reduce efficiency over time.

Many Dallas neighborhoods also have a mix of older and newer construction, meaning duct systems vary widely in age and condition. Leaky or poorly insulated ductwork, common in older Dallas homes, forces the system to work harder to maintain temperature, which can lead to premature wear. Dust and pollen levels in North Texas can also clog filters and coils more quickly than in less arid climates, restricting airflow and straining the system.

Refrigerant leaks, worn electrical connections, and dirty condenser coils are among the most common causes of AC breakdowns in this area. Homes with older attic-mounted units can also experience increased strain during the summer months, since attic temperatures in Dallas regularly climb well above outdoor air temperatures, making the unit work harder just to stay ahead of the heat.

Foundation movement is another factor that often gets overlooked. The clay-heavy soil found throughout much of Dallas expands and contracts with seasonal moisture changes, and that shifting can loosen ductwork connections or cause outdoor units to become out of level over time. A thorough inspection helps identify which of these factors is affecting your specific system so the right fix can be made the first time, rather than treating symptoms without addressing the root cause.

How We Handle Your AC Repair

When you call Ellis AC & Furnace Repair, one of our NATE-certified technicians will arrive in a fully stocked service vehicle ready to diagnose your system on the spot. We start by checking refrigerant levels, electrical components, and airflow to pinpoint the exact issue rather than guessing at a solution. Once we know what’s wrong, we walk you through the findings in plain language and provide an honest, upfront price before any work begins.

Most common repairs can be completed during the same visit, thanks to our well-equipped trucks and experienced team. Our technicians carry a wide range of parts for the most common residential systems found across Dallas, which means fewer return trips and faster relief from the heat. If a part needs to be ordered, we will let you know the realistic timing and keep you updated until the repair is finished.

We also take the time to check for related issues that could cause problems again soon after a repair, such as a failing capacitor nearing the end of its life or a slow refrigerant leak that has not yet fully surfaced. Our goal is to get your home comfortable again as quickly as possible without cutting corners on the quality of the repair, and to leave your system in a condition that holds up through the rest of the Dallas summer.
