We provide independent Lennox service across Irving: AC repair, furnace repair, heat pump repair, installation, and tune-ups. The one thing that makes our Lennox work here different is that we read the house as closely as the equipment. In a city where a 1970s south Irving ranch and a 2000s Las Colinas two-story can share the same refrigerant circuit design but not the same airflow problems, we diagnose the ductwork and attic conditions first and the box second. We’re not affiliated with Lennox and we’re not an authorized dealer, but we know these systems cold. Call (855) 473-9031 and we’ll get you scheduled.

Why Irving Residents Choose Us for Lennox Service
You shouldn’t have to explain your equipment to your technician. When we open the panel on a Lennox, we recognize the layout before we touch a meter. We work on the equipment most North Texas homeowners already own, and Lennox is one of nine brands we’re certified to service, alongside Carrier, Trane, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Nine brands, one standard, and that standard is the Kingsley bar: the job is either done right or it isn’t finished.
Ricardo Radcliffe grew up near Las Colinas and has spent his whole career on HVAC systems across the Metroplex. He trained at Tarrant County College, spent well over a decade in the trade before starting Kingsley AC Repair in 2014, and brought to Irving a habit neighbors recognize: he tells you what he found, not what he wants to sell you. A Lennox call in Irving gets the same treatment every time.
You get a real appointment window, fast dispatch from 7am to 7pm, Sunday through Friday, and a technician who works on nothing but HVAC. No plumbing, no electrical side jobs, no learning your system on your time.

Common Lennox HVAC Problems We Solve in Irving
Lennox equipment has its own set of predictable failure points. Pair those with Irving’s climate and housing stock and you get a short list of calls we run frequently:
- Condensate pan and drain line clogs. Lennox air handlers in south Irving attic installations are often sitting above drain pans that fill with algae and debris every season. When that drain stops moving, the pan overflows into ceiling drywall and drives indoor humidity way up, made worse by undersized 1970s ductwork that already limits airflow.
- Capacitor and contactor burnout. Long stretches above 100°F push a Lennox compressor and condenser fan motor hard. A weak capacitor is one of the most common reasons a system won’t cool, and we find them failing more in older slab homes where attic temperatures climb past 140°F and heat-soak the components.
- Cracked heat exchangers in Lennox furnaces. In the older single-story ranches with original ductwork, restricted airflow puts steady stress on the heat exchanger. We find cracks in Merit and Elite furnaces during tune-ups, and that’s a carbon monoxide risk serious enough to stop everything until it’s addressed.
- Refrigerant leaks at Lennox indoor coils. Lennox evaporator coils are vulnerable to formicary corrosion, and Irving’s humid summers give it the conditions it likes. Low charge and frozen lines show up as symptoms, but we always leak-test before adding refrigerant so we’re not masking a coil that needs replacement.
- Heat pump struggles in hard freezes. A Lennox XP Series heat pump has to handle both a Texas summer and the occasional hard freeze like the 2021 Uri event. Frozen condensate lines, blocked defrost cycles, and strained reversing valves are what we end up fixing when the weather swings.
Lennox Service in Irving: What Local Conditions Mean for Your Equipment
Here’s the insight that shapes every Lennox call we run in Irving. In the older ranch homes near downtown Irving and along the old Texas Stadium corridor, many still have undersized, leaky ductwork buried in low attic space where summer temperatures climb past 140°F. Those systems lose cooling capacity and ice up because of duct static pressure problems, not because of refrigerant charge. A Lennox condenser gets blamed for a duct system that’s the real culprit. We check duct design and attic ventilation before we condemn a Lennox compressor. That’s a step many suburban techs skip, and it’s the difference between a repair that lasts and a service call that comes back in August. Irving’s mix of 1960s slab homes and newer Las Colinas and Valley Ranch builds makes this a street-by-street read, not a one-answer fix.
Lennox Models & Products We Service in Irving
Our service covers the Lennox product families common to North Texas. That includes the Merit Series air conditioners (14ACX, 13ACX) and furnaces (ML180, EL180), the Elite Series (XC21, XC20, XC16 air conditioners; SL280 and EL296V furnaces), the Dave Lennox Signature Collection (XC25, SL22 air conditioners; SLP98V furnace), Lennox heat pumps in the XP Series, and the MLA and MPA mini-split systems.
For critical components like control boards, blowers, and heat exchangers, we use OEM Lennox parts. For capacitors, contactors, and motors, we use quality aftermarket parts when they meet or exceed OEM specs. That’s the practical part of “quality parts that fit”: a part that fits the bracket but not the spec is a future callback.

FAQs – Lennox HVAC in Irving
In Irving homes it’s often an airflow restriction from old undersized ductwork before it’s ever a refrigerant charge problem. Iced lines can come from a dirty filter, a restricted evaporator coil, or duct static pressure, so we check the full air path before we hook up gauges. Call (855) 473-9031 and we’ll come look with the right order of tests.
Once a year, before heating season. Our tune-up runs $80 to $200 and it’s when we catch heat exchanger cracks and failing components while they’re still cheap to address. We don’t work on Saturdays, so call (855) 473-9031 to book a slot Sunday through Friday, 7am to 7pm.
At 12 to 15 years old with a major failure (compressor, coil, or heat exchanger), replacement is usually the honest answer. Below that age, or with a smaller repair, repair often wins. We give you the numbers both ways so you’re not guessing. Call (855) 473-9031 for a written fixed price on either path.
We use OEM Lennox parts for critical components and quality aftermarket parts for wear items, and we’ll tell you which is going in before we install it. We don’t stock every part ever made, so a rare component may need to be ordered. Call (855) 473-9031 and we’ll confirm what’s needed for your system.
Heat pumps are designed to run in cold weather, but a hard freeze exposes blocked defrost cycles, frozen condensate lines, and reversing valve problems all at once. Most Irving homeowners never think about their heat pump until the pipes are already at risk. Call (855) 473-9031 for a diagnostic before the next freeze.
