AfterLennox HVAC in Fort Worth, CA | Brandt HVAC
We’re Brandt HVAC, and we provide independent Lennox in Arlington and across Fort Worth. Quick answer: we diagnose and repair Lennox ACs, heat pumps, and furnaces in Fort Worth homes, and we know exactly what this city’s attics and Blue Northers do to Lennox equipment. Call (984) 538-9003 for a free estimate. We’re not a manufacturer-authorized shop, and that’s the point. We’ll tell you whether that Signature heat pump board or Merit furnace inducer is worth fixing based on what we see in Fort Worth, not on what a corporate playbook says.
Why Fort Worth Residents Choose Us for Lennox Service
Devin Marlowe, our owner and lead technician, cut his teeth on Lennox communicating systems in Southern California before bringing that depth here. He’ll tell you the same thing our techs tell every Fort Worth homeowner: a Lennox system is only as good as the air moving across it and the attic it lives in. Fort Worth homes punish equipment differently than Dallas or Houston. We stock OEM Lennox boards, coils, and inducer motors locally, so we’re not waiting on a warehouse in another state when your heat pump strands you in aux-heat during a 40-degree temperature drop. Every Fort Worth job gets a written price before work starts, and every our Furnace Repair in Fort Worth carries our 365-Day Done Right Promise. If it fails, we come back free.
Common Lennox HVAC Problems We Solve in Fort Worth
- Variable-speed and iComfort board failures in hot attics. Fort Worth’s west-facing attic air handlers sit in 140 – 150°F heat all summer, and Lennox Signature SL28XP and Elite EL18XPV boards cook in that environment. The system throws E-codes, cooling output drops, and the homeowner can’t clear the fault. We swap OEM boards and verify the system communicates before we leave.
- Microchannel coil leaks on Merit and Elite lines. Fort Worth’s hail seasons and hard freezes are brutal on Lennox microchannel outdoor coils, especially the tube-to-header joints. We see this on EL16XC1 and ML14XC1 units in Wedgwood, Ridglea, and Stop Six more than anywhere else. We pressure-test, braze or replace with OEM coils, and recharge to spec.
- Reversing valves sticking on heat pumps. When a Blue Norther slams Fort Worth, a Lennox heat pump with a sticky reversing valve drops into auxiliary-only heat. That’s what happened during Winter Storm Uri, and we still see it each January. We replace the reversing valve, check the defrost board, and restore full heat before the next front.
- Inducer motor and pressure-switch faults on ML and EL furnaces. Fort Worth’s ice-storm power flickers beat on furnace inducer motors and pressure switches. We replace them with OEM parts, then confirm the system’s temperature rise is within Lennox spec. Cracked heat exchangers in 15 – 20 year old furnaces in Wedgwood and Ridglea are a regular call this time of year.
- Undersized return-air chases choking high-SEER upgrades. Fort Worth’s 1950s – 1970s slab homes often have original return chases sized for low-efficiency equipment. When homeowners upgrade to a Lennox variable-speed system, the new blower can’t pull enough air, and the system never hits rated capacity. We open up returns and modify ductwork before the equipment goes in.
Lennox Service in Fort Worth: What Local Conditions Mean for Your Equipment
Fort Worth’s mid-century neighborhoods overwhelmingly use attic-mounted air handlers, and summer attic temperatures routinely exceed 140 – 150°F by afternoon. That’s not a minor detail; it’s the dominant fact of Lennox service here. A condenser on a west-facing roof deck in Ridglea absorbs heat all afternoon, and the capacitors, refrigerant line insulation, and control boards inside get roasted well short of their rated lifespan. A Lennox system that’s “only” ten years old in a Dallas suburb may still have life in it. In Fort Worth, that same unit on a west-facing deck may already be on borrowed time. We factor attic orientation and roof deck exposure into every repair-or-replace call, because it changes the honest answer.

FAQs – Lennox HVAC in Fort Worth
It’s usually a repair. A properly working Lennox heat pump should handle a 30 – 40°F temperature drop without going into emergency heat exclusively. If it’s dropping to aux-heat-only every time a front blows through, you likely have a sticking reversing valve, a failed defrost board, or a refrigerant charge issue. During Winter Storm Uri, Fort Worth homes with hidden reversing-valve problems had no backup heat at all. We check the reversing valve, defrost board, and charge, then tell you exactly what’s failing. Call (984) 538-9003 to schedule a diagnostic.
In Fort Worth, a 10 – 12 year old attic-mounted Lennox unit has lived through more thermal abuse than the same unit in a milder climate. If it’s a Signature variable-speed system with a failed compressor or a Merit with a cracked heat exchanger, replacement often beats repair. But if it’s a capacitor, contactor, or inducer motor, repair makes sense. We’ll give you the straight answer based on what we find in your specific attic. Call (984) 538-9003 and we’ll come look.
Yes. On communicating Lennox systems, we use OEM boards, coils, reversing valves, and heat exchangers. Aftermarket drop-ins on variable-speed or iComfort systems create communication faults and fail again quickly. We’d rather your repair hold. For a free estimate, call (984) 538-9003.
Often not, and this is where Fort Worth is different from Dallas. Our mid-century slab homes frequently have original return-air chases sized for low-efficiency equipment. A modern high-SEER Lennox variable-speed blower needs more air across the coil, and if the return can’t handle it, the system never reaches rated capacity. We’ll measure static pressure and tell you if duct modification is required before the equipment goes in. Call (984) 538-9003 for a full assessment.
For most Fort Worth AC Repair jobs on Lennox systems, expect $150 – $650. Furnace repairs land between $150 and $700. A capacitor or pressure switch is on the low end; a compressor or heat exchanger is on the high end. We hand you a written price before any work starts, and the repair carries our 365-Day Done Right Promise. Call (984) 538-9003 for an exact quote.
