We service every Lennox furnace, heat pump, and air conditioner in Irving as an independent shop, not a factory dealer. What makes our Lennox work different here is simple: we know which units fail in which Irving neighborhoods and why, which means we show up knowing what to look for before we even open the panel. Call (430) 213-5796 and you’ll get a live person, not a call center.
Why Irving Residents Choose Us for Lennox Service
Lennox builds good equipment, but Irving has a way of finding its weak spots. The humid air off Lake Carolyn, the mineral-heavy Trinity River water, and summers that push past 100 degrees put real stress on heat exchangers, condensate pans, and inverter boards. Our technicians have been under enough Irving attics to know exactly what that stress does to a Lennox over time.
Victor Mancini grew up learning the trade at Los Angeles Trade-Technical College and has spent decades turning a wrench on everything from rooftop package units to the old furnaces Oak Cliff homeowners still swear by. He built this company around one idea: tell the customer the number before the work starts. Everything else follows from that.

Common Lennox HVAC Problems We Solve in Irving
- Rusted secondary heat exchangers on SLP98V and G61MPV furnaces. In Irving, the combination of hard water vapor from the Trinity basin and attic temperatures near 130°F causes hairline cracks years earlier than you’d see in drier cities. We check for this every fall.
- Corroded condensate drain pans and clogged lines on XC and XP heat pumps. Rapid algae growth from our heat and humidity clogs lines fast. Add mineral scale from hard water, and you get a pan that rusts through and drips into the closet or hallway.
- Failed inverter boards and communication faults on XC25 and XP25 units. Voltage spikes during the storm season around DFW Airport knock these proprietary boards out. We stock common replacements because waiting two weeks for a board in July isn’t an option.
- Short-cycling and overheating on Merit 13ACX and ML195 units. Many 1980s tract homes south of 183 still have mismatched original indoor coils. That mismatch makes a newer outdoor unit work harder and fail sooner than it should.
- Clogged condensate lines across all Lennox lines in Irving. Continuous runtime from May through September means the line never dries out. It’s the single most common service call we run in this city.
Lennox Service in Irving: What Local Conditions Mean for Your Equipment
Here’s something Irving-specific you won’t hear from a generic Lennox shop. In the Valley View neighborhood, a Lennox SLP98V from 2015 can have a cracked secondary heat exchanger not because of age, but because of the corrosive combination of Trinity River water vapor and attic heat. We see this failure far more in Irving than in Dallas or Coppell, and it maps directly to the older homes where original ductwork pulls humid attic air across the heat exchanger all summer. If your Lennox furnace is eight to ten years old and sits in an attic, get the heat exchanger inspected through our Furnace Repair in Irving before heating season. Radiant cracks leak carbon monoxide. That’s not a scare tactic; it’s what we find.
Our tech pulled a rusted Lennox SLP98V from a home on Rochelle Boulevard near Valley View. The secondary heat exchanger had hairline cracks from years of hard water vapor condensing in the attic. We replaced it with an OEM heat exchanger, flushed the condensate line clogged with mineral scale, and added an inline strainer to prevent future buildup. Then we recommissioned the system with a full combustion analysis. That’s the level of care an Irving Lennox deserves.
Lennox Models & Products We Service in Irving
We work on the full Lennox line: Signature Collection (SLP98V, XC25), Elite Series (EL296V, XC16), Merit Series (ML195, 13ACX), and older Dave Lennox Signature Collection furnaces like the G61MPV. When it comes to parts, we quote genuine Lennox OEM first, especially for anything under warranty or inverter boards where compatibility matters. For older Merit units where a factory part has a two-week lead time, we’ll recommend a proven aftermarket option so you’re not sitting in a hot house. We carry common Lennox parts in our Dallas stock, which means faster turnaround for Irving calls.

FAQs – Lennox HVAC in Irving
Irving’s hard water vapor, carried into attics from the Trinity River basin, condenses on the inside of the heat exchanger and attacks the steel. Combined with attic temperatures near 130°F in summer, the corrosion accelerates. That’s why we inspect these every fall, even on units under ten years old.
You can replace just the board. We keep common XC25 boards stocked, so most Irving replacements happen same-week rather than waiting on a factory order. The board is typically under the unit’s parts warranty for ten years if registered. If the board failed from a storm surge, we’ll check the surge protection too, so it doesn’t happen again. Call (430) 213-5796 and we’ll diagnose it properly.
Could be either, but breaker trips in Irving apartments most often trace to our AC Repair in Irving finding a failing compressor or a shorted capacitor overheating on 100°F days. It’s a safety issue, so don’t keep resetting the breaker. We’ll test both and give you the written price before doing any work.
No. Federal law protects your warranty as long as the work is performed by a licensed contractor using approved parts. We’re independent, not factory authorized, and that’s the point: we fix what’s actually failing without steering you toward a new Lennox you don’t need.
Every six months, and more often if the line runs through an unconditioned attic. In Irving, algae and mineral scale build up fast during our long cooling season, and a clogged line can soak a ceiling in hours. We include the condensate flush in every furnace tune-up. Call (430) 213-5796 for a visit at a flat rate.
