If your Lennox system is acting up in Garland, we can get a technician to you fast, usually the same day you call. Dalton Heating & Air Dallas provides our AC Repair in Garland as independent Lennox service, and we know these units inside and out, especially the older ones still cooling 1960s and 1970s ranch homes. We are not a Lennox dealer or authorized affiliate. We are an independent shop, and Marco Benitez, our owner and lead technician, has spent two decades turning wrenches on Lennox equipment across Texas. Call (254) 280-5320 for a free estimate over the phone or at your door.
What makes our Lennox work different here comes down to one thing: we spend more time in Garland attics and backyards than any manufacturer rep ever will. The way a Lennox evaporator coil behaves in a humid Garland July is not the way it behaves in a showroom. We know the difference.
Why Garland Residents Choose Us for Lennox Service
Lennox builds good equipment. But good equipment still wears out, and in Garland, it wears out faster than the manufacturer’s mileage estimates suggest. That is where we come in. We work on Lennox Elite, Merit, and Signature Series systems every week, from the XC16 air conditioner to the SLP98V furnace to the XP25 heat pump. Lennox sales & service is our bread and butter, even though we are independent of the manufacturer.
Marco grew up in East Los Angeles and learned the trade at Los Angeles Trade-Technical College before spending the next two decades on residential and light-commercial HVAC across Texas. He and the crew have been running calls in Garland long enough to recognize a Belt Line Road ranch home’s duct layout from the street. Every job gets a written price before work starts, a written guarantee on the repair, and a technician who shows up inside the stated window. That is The Garrison Standard, the operating code we have followed since 2003.
We stock common Lennox parts locally, so a capacitor or ignitor replacement does not mean waiting three days on a warehouse truck from Fort Worth. Faster parts mean faster comfort. In August, that matters.

Common Lennox HVAC Problems We Solve in Garland
These are the calls we run over and over again in Garland, tied to the way Lennox equipment fails in this specific climate and housing stock:
- Evaporator coil leaks in older Lennox units. Garland’s humidity stays high from May through September, and the coil inside your air handler sees constant condensation. On Lennox systems from the 1990s and early 2000s, the copper and aluminum joints corrode and develop pinhole leaks. We find these all the time in 1970s ranch homes with original equipment still hanging on.
- Capacitor failures in Lennox condensing units. A capacitor is a small cylinder that gives the compressor and fan motor the electrical kick they need to start. Garland regularly sees stretches of 100°F+ days, and your Lennox condenser runs for weeks without cycling off. That heat soaks into the capacitor and it swells, leaks, or dies. The symptom is usually a unit that hums but won’t start.
- Ignitor failures in Lennox gas furnaces on the first cold snap. Garland winters are mild, so furnaces sit idle for eight months. The first night it dips into the 30s, everyone fires up the heat at once. Lennox hot surface ignitors, the part that lights the burner, crack from thermal shock after long idle periods. We replace them with OEM parts the same day.
- Compressor burnouts in R-22 Lennox systems. If the condenser coil is clogged with cottonwood and oak pollen from a Garland spring, the compressor runs hotter and hotter until it fails internally. This is the most expensive Lennox failure we see, and it usually pushes homeowners toward replacement rather than repair.
- Refrigerant recharge needs on Lennox ACs. A refrigerant recharge means topping off the cooling fluid your system needs to reach set temperature. On older Lennox units with slow leaks, we can recharge and get you cooling again. But if the leak is in the coil, we will show you the numbers and let you decide if another recharge makes sense.
Lennox Service in Garland: What Local Conditions Mean for Your Equipment
Here is something you will not read on a generic Lennox service page: Garland’s older neighborhoods near Downtown have a disproportionate number of Lennox R-22 systems still running, and many of those units only get replaced after a compressor burnout that started with a clogged condenser coil. Cottonwood and oak pollen blow in from every direction in spring, and those tiny fibers pack into the coil fins like felt. The coil cannot reject heat. The compressor runs at higher pressure and temperature. Eventually it burns out, and the homeowner is looking at a $3,500 to $7,500 replacement instead of a $300 coil cleaning. Marco has walked this exact scenario with homeowners off Belt Line Road and around Downtown Garland more times than he can count. If your Lennox unit is running R-22, which the EPA has largely phased out of production, the math on repair versus replace changes fast. We give you the real numbers and let you decide.
Lennox Models & Products We Service in Garland
We work on the full Lennox residential lineup. The Merit Series, including the ML14XC1 air conditioner and ML180 furnace, shows up constantly in Garland’s starter homes and rental properties. The Elite Series, like the EL296V high-efficiency furnace and XC16 AC, is common in 1980s two-story homes that got an efficiency upgrade sometime in the 2000s. The Dave Lennox Signature Collection, including the XC25 variable-capacity AC and XP25 heat pump, is the top tier, and we service those too with our Heat Pump Installation in Garland when replacement makes sense.
When longevity is the priority, we use genuine Lennox OEM parts. When a Garland homeowner on a budget needs a lower-cost option, we offer quality aftermarket parts and tell you exactly what the tradeoff is before you decide. No surprises at the door.

FAQs – Lennox HVAC in Garland
Lennox evaporator coils leak more in Garland because the combination of high humidity and months of continuous summer operation causes condensation-related corrosion at the coil joints. Homes from the 1960s through 1980s with original Lennox equipment are the worst cases we see. The fix is usually a new coil, and we will quote it in writing before starting.
We can recharge an old Lennox R-22 system, but R-22 refrigerant is largely phased out of production, so the per-pound cost has climbed steadily. If the leak is small and the unit is otherwise sound, a recharge can buy you another season or two. If the compressor is on its way out or the coil is leaking, replacement usually makes more sense. We will show you the repair cost and the replacement cost side by side so you can make a clear call. Call (254) 280-5320 and Marco can walk you through the math.
The first cold snap brings a wave of failed hot surface ignitors and dirty flame sensors on Lennox gas furnaces that have been idle for eight or nine months. The ignitor cracks from thermal shock when it heats up after a long rest. We stock these parts locally and replace them the same day so you are not stuck without heat when the temperature drops. Call (254) 280-5320 if your Lennox furnace won’t fire.
We use genuine Lennox OEM parts when a repair needs to last, and we stock the most common ones locally for fast Garland turnaround. We also offer quality aftermarket options when the budget is tight, and we explain the difference in plain terms so you decide with full information. Either way, the repair carries our written full-year guarantee.
Once a year, and spring is the right time in Garland, before the heat arrives. A spring tune-up catches pollen-clogged condenser coils, weak capacitors, and low refrigerant before they become an August breakdown. In Garland’s climate, where the AC runs almost continuously for months, yearly service is not a luxury. It’s the cheapest insurance you will buy for your Lennox. Call (254) 280-5320 to schedule a tune-up; it runs $80 to $200 and includes a written report of what we found.
