Lennox HVAC in Keller, TX | Halden Heating and Air Fort Worth

We’re Halden Heating and Air Fort Worth, and we provide our AC Repair in Keller with independent Lennox service and a written price before any work starts. If you own a Lennox system here, the one thing that makes our work different is that we’ve spent years inside the quirkiest Lennox equipment, so we know which failures hit hardest in Keller’s specific housing stock. We’re not a factory dealership, which means you skip the inflated overhead and still get genuine Lennox parts where they matter. Call (817) 632-5499 and you’ll talk to a live person, not a phone tree.

Our Lennox sales & service experience runs deep, from the oldest R-22 Elite 10s still cooling Keller bedrooms to current variable-speed Signature systems. Andre Fuller, our owner, picked up the trade at Los Angeles Trade-Technical College and has been turning wrenches on Lennox equipment for decades. The guy quotes a flat price before anyone opens a panel because he remembers sitting with a surprise bill once and decided he’d never do that to a homeowner. Flat price up front, cool house by tonight.

Why Keller Residents Choose Us for Lennox Service

Most HVAC companies in Keller can swap a capacitor on any brand. Fewer can tell you why your SLP98V keeps throwing an E312 fault code or whether an R-22 evaporator coil leak on a 2004 Elite 10 is worth repairing. We can, because we’ve been inside these exact systems in Keller homes for years. Our techs know which Lennox parts fail under triple-digit attic heat and which ones hold up fine. We stock genuine Lennox factory parts for critical components like gas valves and control boards, but we’ll also tell you when a top-tier aftermarket capacitor outlasts the OEM spec. That’s the kind of straight answer Keller homeowners call us for.

Serving Keller also means knowing the local houses. We cover the whole city, from Hidden Lakes to Marshall Ridge to the older streets near Bear Creek Park. If your Lennox system sits in a tight attic closet or a hot garage, you want a tech who already knows what that means before they climb the ladder. Every repair comes with a written guarantee. If it fails within the coverage window, we come back at no charge, automatically. No arguing, no fine print.

Common Lennox HVAC Problems We Solve in Keller

• Lennox gas furnace ignitor failures during cold snaps. Voltage spikes from Texas storms that roll through Keller can cook an ignitor overnight. When the first freeze hits, your furnace clicks but won’t light. We keep common Lennox ignitors on our trucks so we can usually get heat back the same day.
• ECM blower motor module burnouts on variable-speed Signature models. The SLP98V and XC25 are brilliant machines, but their ECM modules don’t love attic temps above 130°F in Keller summers. We’ve replaced enough of them to know the warning signs: intermittent airflow, a humming blower, or a system that runs but won’t move air.
• R-22 evaporator coil leaks on 2000s Elite 10 systems. Keller has thousands of these aging Lennox units. During a triple-digit week, a small coil leak turns into a frozen indoor coil and a house that won’t cool below 80. We’ll give you an honest repair-versus-replace quote before you spend money on a dying system.
• Capacitor breakdowns on 13-16 SEER Lennox condensers. Continuous high-head pressure in July and August kills capacitors faster in Keller than almost anywhere. It’s the number one reason your outdoor unit hums but the fan won’t spin. We keep high-temp aftermarket capacitors on every truck for same-day fixes.
• Secondary drain pan failures in tight attic utility closets. This one is Keller-specific. In Hidden Lakes and Marshall Ridge, many original Lennox installs sit in cramped attic closets with undersized return air. Sweating plenums and overflowing secondary drain pans are a June ritual here. We check it every visit, not just when you call about a wet ceiling.

Lennox Service in Keller: What Local Conditions Mean for Your Equipment

Here’s something you won’t read on a generic Lennox page: Keller’s Hidden Lakes and Marshall Ridge subdivisions have a builder-era duct design problem that neighboring cities largely dodged. Many original Lennox R-22 systems were installed in tight attic utility closets with return air sized too small for the square footage. By the second week of June, when daytime highs settle past 95, our techs expect to find sweating plenums and secondary drain pan failures in those neighborhoods. Southlake homes from different builders and eras rarely see the same pattern because their return air was often spec’d larger. If your Keller Lennox system freezes up or trips its float switch every summer, the root cause may not be the equipment. It’s the attic it was stuffed into. We fix the equipment and we also know how to address the airflow and drainage issues that cause repeat failures. That’s what local knowledge actually buys you.

Last July, our tech pulled up to a Marshall Ridge home where a Lennox Elite 13 air conditioner had shut down during a 104°F heat wave. The compressor was pulling locked-rotor amps and the capacitor was bulging. We replaced the dual-run capacitor with a high-temp aftermarket unit and added a hard-start kit to save the original compressor. Then we found the secondary drain pan full and the float switch tripped, so we cleared the clogged line. The system was cooling again within the hour. That’s the kind of two-problem call Keller throws at you when the heat really settles in.

Lennox Models & Products We Service in Keller

We service the full Lennox lineup that shows up in Keller homes. The Merit series (ML14XC1, ML180) is the most common builder-grade equipment we see. The Elite series (EL296V, EL18XCV) bridges mid-range efficiency with better humidity control. The Signature series and Dave Lennox Signature Collection (SLP98V, XC25, SL280V, XC21) are the variable-speed top-end units that need techs comfortable with communicating systems and proprietary fault codes.

Our parts approach is simple. We stock genuine Lennox factory parts for safety-critical and system-integrity components: gas valves, control boards, inducer motors, communicating thermostats. For wear items like capacitors and contactors, we use top-tier aftermarket parts when they meet or beat OEM specs. This keeps your repair cost reasonable without cutting corners. And because we keep common parts on our trucks, most Keller calls are one-trip fixes.
