We provide independent Lennox HVAC service in Irving, TX – repair, installation, and heating work on Lennox equipment only, done by technicians who see these systems every week across the DFW market. What makes our Lennox work different is diagnosis: we know the known weak points on Elite and Merit units and check them first, instead of guessing. We handle AC Repair, Furnace Repair, and Heat Pump Repair on Lennox systems throughout Irving. As an independent Lennox service provider, we’re not affiliated with or authorized by Lennox. We just know the equipment. Call (855) 473-9031 for a free estimate.
Why Trust Kingsley AC Repair for Your Lennox HVAC?
You shouldn’t have to explain your equipment to your technician. When we roll up to a Lennox system, we already know the control sequence, the pressure-switch tubing routing on variable-speed furnaces, and which components tend to fail first. That familiarity comes from years of working the nine major brands – Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard – not from a quick reference card.
Kingsley AC Repair was started by Ricardo Radcliffe in 2014, and he grew up near Las Colinas before spending well over a decade in the trade. When he started Kingsley, the intent was a shop that diagnoses fast and doesn’t recommend parts that don’t need replacing. That shows up in how we handle Lennox work: we pressure-test coils and dye them before anyone says “refrigerant leak,” and we read fault codes before we touch a control board. Every job is held to the Kingsley standard, not to whatever closes the ticket fastest.
Warranty-safe practice matters too. We document what we find, use quality parts that fit Lennox equipment, and leave the system in a condition a manufacturer’s warranty review can read clearly. We’re not tied to a warranty agenda on anyone’s behalf, and that keeps our repair advice honest.

Common Lennox HVAC Problems We Fix in Irving
Lennox equipment has recognizable failure signatures. Here are the ones we run into most in Irving, and why they happen:
- Pressure-switch and inducer faults on variable-speed EL296V furnaces. After a summer of high condensate volume, the trap on an EL296V can partially clog. Water backs into the pressure-switch tubing, the switch reads wrong, and the furnace locks out. It almost always shows up on the first cool night, when the system runs longer than it has in months. We clear the trap, check the secondary heat exchanger, and replace the pressure switch if it’s failed.
- Cracked spark ignitors and control-board flame-proving faults on older G61 and G60 furnaces. The ignitor cracks with age and the board can’t prove flame, so it faults out. Sometimes the board itself is the problem. We test both before replacing either.
- Failed dual-run capacitors on XC20, XC21, and ML14XC1 outdoor units. In Irving’s long stretches over 100°F, the condenser fan and compressor start windings take a beating. A weak capacitor shows up as a fan that won’t spin or a unit that short-cycles. It’s a fast, inexpensive repair when it’s caught early.
- Leaking evaporator coils on Elite-series air handlers. These are often misdiagnosed as a refrigerant leak. We pressure-test the coil and use dye to confirm the source before recommending a replacement.
- Frozen or restricted metering devices during hard freezes. North Texas heat pumps, including Lennox XP series units, aren’t used to the kind of cold the 2021 Uri event brought. We see stressed reversing valves and iced coils when temperatures drop hard. A defrost cycle check and a refrigerant charge verification catch most of it.
Lennox Parts & Our Repair-vs-Replace Approach
We stock OEM Lennox ignitors, pressure switches, boards, and capacitors, because the control-timing behavior on Elite and Merit units is picky about aftermarket substitutes. A generic capacitor that fits doesn’t always behave the same, and we’d rather not hand you a repair that fails again in a month. On older G-series furnaces and any Lennox system where parts aren’t in hand, we source directly and get the right component.
On a mid-life Lennox with a cracked heat exchanger or a failed compressor, we give an honest repair-vs-replace number. If the repair makes financial sense, we say so. If it doesn’t, we say that too. Brand-neutral diagnostics means we’re not steering you toward a specific outcome. Call (855) 473-9031 and we’ll walk through what we find before anyone recommends anything.
Our Lennox Service Process – Step by Step
- 1
Diagnosis. We pull fault codes, check the condensate trap and pressure-switch tubing on furnaces, and pressure-test the coil on any cooling call that looks like a refrigerant issue. We verify the problem before we price a fix.
- 2
Repair or install. We use quality parts that fit Lennox equipment, and we install to the manufacturer’s spec so the installation stays warranty-safe. On new installs, we size the system to the home, not to a catalog page.
- 3
Test. We cycle the system through a full call and confirm the fix holds at operating temperature and pressure, not just at startup.
- 4
Warranty documentation. We document what we found, what we replaced, and what we tested, so your Lennox warranty record is clear if you ever need to file a claim.
We were called to a two-story home in Irving where an EL296V furnace kept locking out on a pressure-switch fault during the first cold snap. Our tech found a partially blocked condensate trap flooding the pressure-switch tubing, cleared the drain and the secondary heat exchanger, and replaced the OEM pressure switch; the furnace ran clean through the rest of the heating season. A week earlier we’d swapped a shorted dual-run capacitor on the homeowner’s XC21 condenser that was tripping the breaker. That’s typical Irving service: heating and cooling issues from the same house, handled by the same shop.

AfterLennox Products We Service & Install in Irving
We service and install Lennox gas furnaces, including variable-speed EL296V and EL296E models and Merit Series MLA and MLS units. We work on Lennox air conditioners, from the XC20 and XC21 variable-speed units to the ML14XC1 Merit Series single-stage. Lennox XP series heat pumps are part of our regular work too, which matters in Irving where winter freezes stress heat pumps more than most homeowners expect.
Whatever the equipment, we size and service it for the home it’s actually in. South Irving’s older slab ranches with attic air handlers need different care than the newer two-story builds in Las Colinas and Valley Ranch. We don’t quote from a chart. We quote from what’s in your attic and on your slab.
We Also Service These Brands
Kingsley AC Repair is a multi-brand HVAC shop, and we work on Carrier and Trane equipment with the same depth we bring to Lennox. That matters when a replacement is genuinely the right call: we can speak to how all three platforms compare for your home, your ductwork, and your budget, without steering you toward the brand that pays a referral fee. Nine brands. One standard.
FAQs – Lennox HVAC Service in Irving
No. We’re an independent Lennox service provider, not a dealer and not affiliated with or authorized by Lennox. We’re trained and equipped to service nine major HVAC brands, and Lennox is one of them. We can work with your manufacturer’s warranty documentation, but we don’t speak for Lennox on warranty decisions.
Yes. We stock OEM Lennox ignitors, pressure switches, control boards, and capacitors because the control-timing behavior on Elite and Merit units is picky about aftermarket substitutes. On parts we don’t have on hand, we source directly. Call (855) 473-9031 if you want to know what’s in stock for your system before we come out.
Most Lennox repairs run one to three hours on site once we’ve diagnosed. Capacitor and ignitor swaps are usually under an hour. Coil and pressure-switch work takes longer because we test thoroughly. Installation is scheduled, not same-day, since it requires load calculation and ordering.
Gas furnaces (EL296V, EL296E, MLA, MLS, and older G-series), air conditioners (XC20, XC21, ML14XC1), and XP series heat pumps. We handle repair, replacement, and tune-ups on all of them.
Not when the work is done correctly. We follow manufacturer spec and document every repair, which is what most warranties require. We don’t speak for Lennox on warranty decisions, but we do leave your service record clean. Call (855) 473-9031 with questions.

Almost always a partially clogged condensate trap that floods the pressure-switch tubing. After summer, the trap holds water and debris; when the furnace runs longer on the first cold snap, the switch can’t read correctly and locks out. We clear the trap, check the secondary heat exchanger, and replace the pressure switch if it’s failed. Call (855) 473-9031 to get it booked.
The XC21 runs R-410A, which is still widely available and doesn’t carry the cost premium of legacy R-22. If you have an older Lennox system on R-22, a recharge does cost more. We pressure-test and confirm the leak source before recommending anything. Call (855) 473-9031 if you’re not sure which refrigerant your unit uses.
Not usually. A failed dual-run capacitor is the most common cause: the fan can’t start, the compressor draws high current, and the breaker trips. In Irving’s summer heat, capacitors fail regularly. We test the capacitor and the compressor separately before pricing a fix. Call (855) 473-9031 to schedule a diagnosis.
Often both repairs together are worth it on a G61 that otherwise runs well. If the heat exchanger is cracked or the furnace is well past its service life, replacement makes more sense. We give an honest repair-vs-replace number and let you decide. Call (855) 473-9031 for an estimate.
Once a year, before the heating season, is the right cadence for a heat pump in Irving. Hard winter freezes stress the reversing valve and defrost cycle, and a pre-season tune-up catches issues before the first cold snap. A tune-up is typically $80 – $200. Call (855) 473-9031 to book one.
