Furnace Repair in Garland, TX

Contact Us

Garland is one of the larger cities in Dallas County, and its residential landscape tells a clear story about time. Neighborhoods built in the 1950s and 1960s sit alongside subdivisions from the 1980s and 1990s, and the heating systems inside those homes reflect that same span of decades. Older equipment in an aging home puts a specific kind of demand on a furnace repair company: the technician has to know what they are looking at, understand how the system was built, and be honest about what it will take to keep it running or whether it is time to move on. That is exactly how Ellis AC & Furnace Repair has approached every service call since 1975.

We are family owned, locally operated, and have worked in Garland homes long enough to know this city well. When something goes wrong with your furnace, we will give you a clear diagnosis, a straightforward proposal, and the kind of service that holds up over time.

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.

Signals That Something Is Wrong With Your Furnace

Garland’s winters tend to be mild for long stretches, then sharp and sudden when a cold front moves through. That pattern of inactivity followed by heavy demand is hard on furnace components, particularly in systems that have not had routine maintenance in a few years. The signs below are worth paying attention to before the temperatures bottom out.

  • Your furnace runs but the air from your vents feels lukewarm rather than warm, and your home never reaches the set temperature.
  • The system cycles on and off in short bursts rather than running through a complete heating cycle.
  • You hear sounds during operation that were not there last season, including popping, rattling, or a high-pitched squeal at startup.
  • Some areas of your home are comfortable while others stay noticeably cold, even with the system running continuously.
  • Your heating bills have increased from one winter to the next without any change in how you use the system.
  • The furnace produces an odor when it first fires up that does not dissipate after several minutes of operation.
  • Your carbon monoxide detector has alarmed, even briefly, while the furnace is running.

If your system is showing any of these signs, scheduling a diagnostic visit before the next cold snap is far better than waiting until a full breakdown forces the issue.

What Tends to Go Wrong in Garland Homes

Garland’s housing stock is dominated by homes built between 1950 and 1990, and a large portion of those homes have ductwork, equipment, and infrastructure that has never been fully updated. The city also sits in a corridor that sees strong northerly winds during cold fronts, which can drive cold air into attics and crawl spaces and accelerate heat loss through poorly sealed duct systems. Combine that with the Blackland Prairie soil conditions that cause consistent foundation movement across much of eastern Dallas County, and you have a set of conditions that wear on HVAC systems in specific, predictable ways. The following are the problems our technicians encounter most often in Garland.

  • Heat exchangers that have developed cracks over years of thermal expansion and contraction, particularly in furnaces that are 15 years old or older.
  • Original ductwork from the 1960s and 1970s that was never designed for modern airflow requirements and has developed leaks at joints and connections.
  • Ignition system failures in mid-generation equipment from the 1990s and early 2000s that is now reaching the end of its reliable service life.
  • Blower motors that have worn down after years of year-round use, since the same motor handles both heating and cooling cycles.
  • Dirty evaporator coils and clogged filters that restrict airflow and force the heat exchanger to overheat and trip the high-limit switch.
  • Thermostat calibration issues in older homes where wiring has been modified over multiple renovation cycles.

Most of these issues are diagnosable and repairable in a single visit when they are caught early enough, which is one of the strongest arguments for annual maintenance before each heating season.

How We Approach Every Furnace Repair

There is a version of HVAC service where a technician arrives, identifies the most obvious symptom, replaces the part, and leaves. We do not operate that way. In a home with a furnace that is 20 or 25 years old, fixing the immediate failure without evaluating the rest of the system often means the homeowner is calling again in two months with a different problem. Our technicians are trained to look at the full picture, and they take the time to do it.

Every repair visit at Ellis starts with a complete system evaluation. We check the heat exchanger, the ignition assembly, the blower, the filter, the flue, the thermostat, and the ductwork connections before we write up a proposal. You will receive a written estimate that breaks down exactly what we found and what we recommend, and no work begins until you have approved it. We handle gas furnaces, electric furnaces, and heat pump systems, and our trucks are stocked to handle most repairs on the first visit without requiring a parts order and a return trip.

Inside a Service Call in Firewheel

Firewheel is one of Garland’s newer master-planned communities, with homes that were built primarily in the late 1990s and 2000s. Those homes are now old enough that their original HVAC equipment is approaching or past its expected service life, and we have been seeing more calls from that area as systems start to show their age. Last winter, a homeowner named Susan contacted us after her furnace stopped producing adequate heat about three weeks into a cold stretch.

When our technician arrived, he found that the furnace was operational but the heat exchanger had developed a secondary crack that was allowing combustion gases to mix with the circulated air. The issue had not triggered her carbon monoxide detector yet, but it was a genuine safety concern. He explained the finding clearly, showed Susan where the damage was located, and walked her through her options, which included repair of the affected section and full system replacement given the unit’s age and overall condition. She chose replacement, and the new system was installed within two days. She mentioned afterward that she appreciated that the technician never pushed her toward the more expensive option without explaining the reasoning behind it.

That is exactly the kind of company Ellis AC & Furnace Repair has been since 1975.

  • Technicians who average more than 10 years of experience and are factory trained to work on the full range of residential furnace systems.

Fifty years is a long time to stay in one place and keep earning the same community’s trust. We take that seriously, and it shows in every service call we run.

Frequently Asked Questions

How do I know if my furnace is safe to keep running?
If your carbon monoxide detector has alarmed, if you notice a persistent burning smell that does not clear during operation, or if your furnace is producing visible soot or discoloration near the unit, stop running the system and call for service. A cracked heat exchanger can allow combustion gases into your living space without triggering an obvious alarm, which is why annual inspections are important even when a system appears to be functioning normally.
Short-cycling, where the furnace turns on and off repeatedly without completing a full heating cycle, usually points to one of a few causes: a clogged air filter restricting airflow, an overheating heat exchanger tripping the high-limit switch, a thermostat that is not reading temperatures accurately, or an oversized system that satisfies the thermostat call too quickly. A technician can identify the root cause during a diagnostic visit.
A faint dusty smell during the first few cycles of the season is common and usually clears within an hour as accumulated dust burns off the heat exchanger. A persistent smell, a smell of burning plastic or metal, or any odor that resembles combustion gases is not normal and warrants a service call.
Most gas furnaces have a service life of 15 to 20 years with proper maintenance. Systems that have been serviced annually and operated in well-insulated homes can reach the upper end of that range. Systems that have been neglected or that have run in demanding conditions may begin showing significant problems earlier. If your furnace is approaching 15 years old, it is worth discussing its overall condition with a technician during your next service visit.
Yes. We work on furnaces of all ages and are not limited to systems that are currently under manufacturer warranty. For older equipment, we evaluate the repair cost against the remaining service life of the system and give you an honest recommendation about whether repair or replacement makes more sense for your situation.
