Lennox HVAC in Cibolo, TX

Lennox HVAC in Cibolo, TX | Brandt HVAC Co San Antonio

We service Lennox heating and cooling systems across Cibolo as an independent provider, not a manufacturer-authorized shop. For cooling issues, call our Cibolo AC Repair team. That means straight talk on parts, pricing, and when a repair no longer makes sense. One thing sets our Lennox work apart here: we know exactly how Cibolo’s rapid build-out and humid climate stress these units, from frozen Elite heat pumps in Turning Stone to 20-year-old G61 furnaces still chugging along in older neighborhoods. Call (361) 470-8872 for service that starts with a written price.

Why Cibolo Residents Choose Us for Lennox Service

Our techs work on Lennox systems across Cibolo every week, from early-2000s G40 legacy furnaces to brand-new Merit Series heat pumps, so we know the quirks of each generation without relying on a factory training manual. Devin Marlowe, our owner, learned the trade at Los Angeles Trade-Technical College and spent nearly two decades running HVAC calls across the Southwest before building out our San Antonio-area crews. That background means we explain what broke in plain English, not parts-counter jargon.

Every Cibolo job starts the same way: a background-checked, uniformed technician introduced to you by name and photo before arrival, and a written price before any work begins. No exceptions. We stock genuine Lennox OEM capacitors, ignitors, and sensors on our trucks for same-day fixes, and we use quality aftermarket contactors and fan motors where they make sense on out-of-warranty units. If a repair fails within the guarantee period, we return at no charge under our 365-Day Done Right Promise. That’s the whole deal, written down.

Common Lennox HVAC Problems We Solve in Cibolo

• Pressure switch codes on SLP99V and EL296V furnaces. Cibolo’s high humidity breeds algae in condensate traps, which clogs the drain path and confuses the pressure sensor. We clean the trap, flush the line, and verify the switch is reading true before we call it fixed.
• Leaking Schrader valves on Merit Series ML14XP1 heat pumps. I-35 traffic throws salt and road film into the air around Cibolo, and that cocktail eats at outdoor unit valves faster than you’d expect. A slow refrigerant leak shows up as weak cooling or a frozen suction line. We replace the valve core, pull a proper vacuum, and recharge to the nameplate spec.
• High head pressure on Elite Series XC20 outdoor units. Cottonwood from the creeks around Cibolo packs into condenser coils every late spring, and by the time the 95°F days hit, the unit is working against a wall. We clean the coil, confirm airflow across the whole cabinet, and check that the fan motor is pulling its rated amp draw.
• Cracked heat exchangers on legacy G61 furnaces. Mild winters mean these furnaces short-cycle for a decade straight, and the repeated heating and cooling takes a toll. A cracked exchanger is a carbon monoxide risk, not a patch job. We inspect with a camera and show you exactly what we’re seeing before recommending a fix.
• Frozen coils in new construction homes. This one is disproportionately a Cibolo issue, and we’ll get into why below. The short version: undersized return ducts from production builders starve the evaporator coil, and the system ices over even on a normal Texas afternoon.

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

Cibolo grew from about 3,000 residents in 2000 to more than 30,000 today, and that growth produced two very different Lennox populations. Older single-family homes from the 1980s and 90s in established neighborhoods often still run original R-22 systems, many of them Lennox units that are now obsolete and increasingly expensive to recharge. Newer subdivisions built after 2010, particularly Turning Stone and Belmont, got high-efficiency Lennox heat pumps installed by production builders who undersized the return air ducts to save a few dollars per home. The result of that corner-cutting is static pressure that runs too high, evaporator coils that freeze, and homeowners who have been told four different stories about what’s wrong with a system that is only seven years old. Our techs regularly correct this in Cibolo by enlarging the return drop, adding a filter grille if needed, and bringing total external static pressure down to the 0.5 inches the equipment was designed for. That fix is specific to Cibolo’s building practices, and it’s one reason a generic Lennox checklist from another market won’t catch what’s actually happening on your street.

Lennox Models & Products We Service in Cibolo

We service the full Lennox residential lineup: the Dave Lennox Signature Collection (SLP99V furnaces, XC25 heat pumps), the Elite Series (EL296V, XC20), the Merit Series (ML14XP1, ML180), and older G61 and G40 legacy furnaces still common in Cibolo’s pre-2000 homes. That includes Lennox sales & service across every major line, with real diagnostics rather than a swap-until-it-works approach.

On the parts side, we’re particular. Ignitors, control boards, and pressure switches get genuine Lennox OEM parts because that’s where imitation parts cause repeat failures. Outdoor contactors and condenser fan motors on out-of-warranty units often get quality aftermarket components, a choice that can run 30% less for Cibolo homeowners without cutting reliability. We carry common capacitors, ignitors, contactors, and refrigerant in our trucks, so most single-system repairs are finished in one visit to your Cibolo home rather than spread across follow-up trips.

Lennox Service Pricing in Cibolo

Service	Typical Price Range
AC Repair	$150 – $650
Furnace Repair	$150 – $700
AC Installation	$3,500 – $7,500
Maintenance Tune-Up	$80 – $200

Those are real numbers for Cibolo work, parts and labor included. What moves a repair toward the top of the range is usually a failed compressor, an R-22 recharge on a system that still uses the old refrigerant, or an evaporator coil replacement buried in an attic. A capacitor, ignitor, or condensate trap cleanup lands at the lower end. Every Cibolo estimate is free, includes a written price before any work starts, and spells out exactly what the guarantee covers. Call (361) 470-8872 and we’ll tell you what it costs before we touch a screwdriver.
