Garland homeowners know what a North Texas summer feels like from the inside — thermostats climbing past 80 degrees indoors while the outdoor unit struggles to keep pace with triple-digit heat. Positioned in the northeastern corner of Dallas County, Garland experiences some of the longest sustained heat stretches in the Metroplex, with little topographic relief to moderate temperatures during July and August.

Ellis Air Conditioning and Heating has been a trusted name in DFW since 1975, and our crews are well acquainted with the neighborhoods, housing types, and weather patterns that define Garland’s HVAC challenges. From established subdivisions near Firewheel to older homes along Shiloh Road, we arrive prepared — stocked trucks, experienced technicians, and a straightforward approach to getting your system back up and running.

Why Homeowners in Garland, TX Trust 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.

What Our Garland AC Repair Services Cover

Garland’s residential landscape spans several decades of construction, from post-war bungalows in the city’s historic core to sprawling brick homes built during the 1980s and 1990s suburban expansion. That variety means our technicians regularly work on equipment of every age and configuration, and they come prepared for it.

Our AC repair services available to Garland residents include:

Refrigerant leak location and recharge, which becomes especially urgent during Garland’s extended cooling season when even a small leak can leave a system unable to maintain comfortable indoor temperatures.
Capacitor and contactor replacement, two components that degrade quickly under the sustained heat loads that Garland’s outdoor units face from May through September.
Evaporator coil inspection, cleaning, and repair to address the buildup of dust and biological growth that accumulates in systems running through humid spring and summer conditions.
Condensate drain line clearing to prevent the backups and water damage that become more common during Garland’s muggy late-spring weather.
Electrical component and control board diagnostics, particularly relevant given the power disturbances that accompany the severe thunderstorms that roll through northeast Dallas County each spring.
Duct system evaluation and repair for homes where aging or poorly sealed ductwork is quietly undermining cooling performance.

Our aim on every call is not just to restore function but to make sure the system is operating at the efficiency it was designed to deliver — which matters a great deal when you are running AC for five or more months a year.

How to Tell Your Garland Home's AC Needs Attention

Because Garland sits on relatively flat terrain with heavy clay soil and limited natural shade in many newer subdivisions, homes here can heat up quickly when an air conditioning system starts to underperform. The challenge is that some early warning signs are subtle enough that homeowners dismiss them as normal summer behavior until a full breakdown occurs. Paying attention to these indicators can save you from a much larger repair bill — or a miserable weekend without cooling.

The indoor temperature climbs above the thermostat setting during afternoon hours even though the system appears to be running normally.
Airflow from supply vents feels noticeably weaker than it used to, which may point to a failing blower motor or a blocked filter and coil.
The outdoor unit makes unfamiliar sounds — clicking, rattling, or a high-pitched squeal — during startup or operation.
Indoor humidity feels excessive even with the AC running, which often signals that the system is short-cycling and not completing full dehumidification passes.
You notice water pooling near the indoor air handler, typically caused by a clogged condensate drain or a frozen evaporator coil that has thawed.
The system runs almost constantly without cycling off, placing unnecessary strain on the compressor and driving up your energy costs.

None of these symptoms should be waited out. In Garland’s summer climate, a system that is struggling today can be a system that has failed entirely by the end of the week.

Why AC Systems Break Down in Garland

A few specific factors make Garland particularly demanding on residential air conditioning equipment. First, the city’s expansive clay soils shift significantly with seasonal moisture changes — swelling after spring rains and contracting sharply during summer drought conditions. This ground movement stresses the slab foundations that most Garland homes rest on, and over time it can pull duct connections apart at joints, creating air leaks that quietly reduce system efficiency without triggering any obvious alarm.

Second, a large portion of Garland’s housing stock was built before current energy codes took effect, meaning attic insulation is often thinner than recommended and duct systems were designed to looser standards. Systems in these homes work significantly harder to compensate, which accelerates component wear. Finally, the spring storm season across northeast Dallas County is consistently severe — hail, high winds, and lightning strikes are regular occurrences that can damage outdoor condenser units, bend fan blades, and send power surges through system electronics. These are not hypothetical risks for Garland homeowners; they are recurring seasonal realities.

A Look at One of Our Recent Calls in Firewheel

In late June, we heard from Kevin, a homeowner in the Firewheel area of eastern Garland. He had noticed his downstairs living areas were comfortable enough, but the upstairs had been stuffy and warm for about two weeks — tolerable at first, but increasingly difficult to ignore as temperatures climbed into the triple digits.

Our technician found that the evaporator coil on the upstairs air handler had a significant layer of buildup restricting airflow — the result of a filter that had not been changed in over a year combined with the humid spring the area had experienced. The restricted coil had caused the system to ice over periodically, which further reduced its ability to cool the upper floor. After a thorough coil cleaning and a filter replacement, airflow was restored and the system returned to proper operation within the same visit.

Kevin was relieved but surprised at how much difference a dirty coil could make. Before wrapping up, the technician outlined what a routine maintenance visit covers and explained how catching coil buildup in the spring — before the peak cooling season — typically prevents exactly this kind of midsummer disruption.

Frequently Asked Questions

Can Ellis come out the same day for AC repair in Garland?

In most cases, yes. Ellis provides 24/7 emergency service and maintains a large fleet of vehicles across the DFW area, which allows us to dispatch a technician to Garland quickly — including evenings, weekends, and holidays. Same-day service is our goal on every urgent call.

My Garland home feels humid even with the AC running -- is that an AC problem?

It can be. When an air conditioner short-cycles — turning off before completing a full cooling pass — it loses its ability to pull adequate moisture out of the air. This is a common symptom of an oversized system, a refrigerant issue, or a dirty coil restricting airflow. A technician can identify the cause and recommend the appropriate fix.

Is it worth repairing an older AC system in Garland, or should I just replace it?

It depends on the age of the equipment, the nature of the failure, and how efficiently the system has been running. As a general guideline, systems under 10 years old with minor to moderate failures are strong candidates for repair. Systems that are 15 years or older with compressor or coil failures are often better candidates for replacement. Our technicians will lay out both options clearly so you can decide what makes sense for your situation.

How does Garland's clay soil affect my home's HVAC system?

Garland’s expansive clay soil shifts with moisture levels throughout the year — swelling during wet periods and contracting during droughts. This movement can gradually pull apart duct connections at joints and seams, allowing conditioned air to escape into unconditioned spaces like attics and wall cavities. The result is reduced cooling performance and higher energy bills. A duct inspection can identify whether soil movement has compromised your system’s delivery efficiency.

What maintenance does an AC system need in the Garland area?

At minimum, we recommend a professional tune-up each spring before the cooling season begins. This typically includes coil cleaning, refrigerant level verification, electrical component inspection, drain line flushing, and a check of airflow and system pressures. Given Garland’s demanding summers, catching small issues in April is far less disruptive — and far less expensive — than dealing with a breakdown in August.
