We provide independent Lennox service across Irving, TX, handling AC repair, furnace repair, and heat pump repair on the equipment you already own. What makes our Lennox work here different is that Irving isn’t one housing market. We serve both the older ranch homes on slab in the south and central neighborhoods and the vertical fan-coil stacks and rooftop packaged units in the Las Colinas and Valley Ranch towers, and those two systems fail in completely different ways. Call (866) 964-4152 and we’ll sort out which one you’re dealing with. We answer 24/7.
Why Irving Residents Choose Us for Lennox Service
Lennox systems have a loyal following in North Texas, and that loyalty means plenty of 10- to 20-year-old units still running on Irving slabs and in condo closets. Our technicians can read a Lennox equipment tag and know what they’re looking at without a research project. Our technicians have up to 8 years of experience with the brand’s residential lineup: the Merit air conditioners that were common in tract building, the Elite variable-speed systems, the Signature inverter equipment, and the ductless mini-splits. We work on all of them.
An independent shop is what we are. We’re not a Lennox dealer, not factory-authorized, and not affiliated with the manufacturer. That means when we recommend a fix, it’s based on what your system actually needs, not on a dealer agreement. Scheduling in Irving is straightforward because we know the geography here.
Ranch-home customers in 75061 get a technician with a stepladder and an attic thermometer. Condo owners off the DART line in Las Colinas get a technician who knows to call the building manager about freight-elevator access before the visit. Same phone call, different playbook.

Common Lennox HVAC Problems We Solve in Irving
- Weak run capacitor and pitted contactor on older Merit condensers. Irving’s north-Texas heat dome routinely pushes weeks of 100°F-plus days, and a marginal capacitor on an aging Merit condenser will simply give up mid-afternoon. The compressor tries to start, the contactor takes the hit, and the unit short-cycles on overload. We test capacitance under load, replace both parts, then check the refrigerant charge and the duct sizing.
- Electronic ignition and flame sensor failure on ML180 and EL296 furnaces. The hard-freeze cycles that hit Irving, including the February 2021 event, push these furnaces into repeated cold starts. Hot-surface ignitors crack and flame sensors carbonate up. If your furnace clicks without lighting, that’s usually the pair to check.
- Cracked or plugged secondary heat exchanger. The 1950s-70s ranch homes in 75060 and 75061 often have shallow attic spaces with marginal airflow. That’s a hard environment for a horizontal Lennox furnace with a secondary heat exchanger, and it’s a genuine safety issue. We inspect these carefully.
- Refrigerant leaks at brazed joints and Schrader cores. South- and west-facing condenser pads on Irving slab lots take full afternoon sun and spring hail. The joints and valves on Elite and Signature units weather fast under that exposure. We leak-test and repair rather than just topping off.
- Heat pump reversing valve and defrost problems. Heat pumps in Irving work hard in both summer and winter, and the reversing valve and defrost controls are the first things to go. On a ductless or Signature heat pump, we check the defrost cycle before assuming anything bigger.
Lennox Service in Irving: What Local Conditions Mean for Your Equipment
Irving sits in the DFW heat dome, and the long cooling season means Lennox condensers here run well past their rated duty cycle every year. That single fact stretches service life differently depending on what kind of building you’re in. In a 1960s ranch home on a slab in 75061, the same Merritt-model condenser that served the house for twenty summers may finally stall on a mid-afternoon in August, and the culprit is often a bulging run capacitor paired with a pitted contactor. Your attic ductwork, frequently undersized from the original build, adds load on top of that.
Now step into a Las Colinas or Valley Ranch tower, or a 75038 mid-rise off the DART corridor. The equipment there runs differently. Vertical fan-coil stacks behind closet panels, rooftop packaged units on the roof deck, and ductless systems serving individual units all operate in tighter conditioned spaces with far less thermal swing than a west-facing Texas ranch attic. Failure modes still show up, but the pattern shifts toward fan motors, coil freeze-ups, and condensate drain blockages. Same Lennox nameplate, different service profile.
Lennox Models & Products We Service in Irving
We work on the full spread of Lennox residential equipment. That includes conventional split-system air conditioners, gas furnaces (both 80% and 90%+ efficiency lines), heat pumps, and ductless mini-split systems serving individual rooms or unit clusters. The Merit, Elite, and Signature lines all come through our queue, and the service approach follows the age and condition of each system.
We source parts two ways. When your specific Lennox model needs an exact match, control boards, ignitors, heat exchangers, we go OEM. When a quality aftermarket capacitor, contactor, or TXV does the same job in Texas heat and costs less, we use one and pass the saving along. We don’t stock parts and we don’t claim to; every part we install is ordered to fit your system.

FAQs – Lennox HVAC in Irving
A failed run capacitor is the most common cause, followed by a pitted compressor contactor. Both are cheap parts that take a beating on Irving condensers running through 100°F-plus weeks. A technician tests capacitance under load, checks the contactor, then verifies refrigerant charge. Call (866) 964-4152 for a free estimate.
The condo visit starts with building logistics. In the towers, we coordinate with building management for freight-elevator reservations and work inside riser and fan-coil closets rather than on a backyard condenser pad. A 75061 ranch home means attic access and a slab condenser exposed to full sun. Same Lennox equipment, completely different service call. Call (866) 964-4152 to schedule and we’ll confirm the access requirements beforehand.
Not always. Hot-surface ignitors are fairly forgiving, and a quality aftermarket unit that matches the voltage and physical fit works. Where it matters more is control boards and heat exchangers on later-model Lennox furnaces. Call (866) 964-4152 and we’ll quote the exact part for your model.
Estimated ranges are $150 – $650 for AC repair and $150 – $700 for furnace repair. A tune-up runs $80 – $200, and a full AC installation is typically $3500 – $7500. The written estimate sets the final price. Call (866) 964-4152 for a free estimate.
Yes. Exposed linesets and condensers can split during hard freezes like February 2021, especially on older ranch lots where the pad sits in the open. Cracks usually appear at brazed joints or at the service valve. If you suspect freeze damage, don’t run the system until a technician checks it. Call (866) 964-4152 and we’ll come out.
