Why New Braunfels Residents Choose Us for Lennox Service
We are not a manufacturer-authorized Lennox dealer, and we want that to be clear from the start. We are an independent shop that has spent years servicing the full range of Lennox equipment across Central Texas, from builder-grade Merit series units to premium Signature Collection systems. Our technicians know the quirks of Lennox inverter boards, communicating thermostats, and variable-capacity compressors the way only hands-on repetition teaches. Luis Serrano, our owner, learned the trade at Los Angeles Trade-Technical College and has spent decades doing HVAC work across the Southwest. He built his reputation on careful installs, the kind where thermostat wires are labeled and nothing leaks refrigerant six months later. His approach shapes how we handle every Lennox call in New Braunfels: diagnose first, explain the price in writing, then touch a single tool. For Lennox sales & service, that level of care is what families actually need, not a sales script.
Every visit includes the Cedarwell Care Promise: shoe covers and drop cloths inside your home, a written price before any work starts, and a photo of the clean-up sent before our crew leaves. Our techs are background-checked, uniformed, and follow the C.A.R.E. values code: Clean up like it’s their own home, Ask before moving anything, Respect your family’s time, and Explain the price before the work. If your Labrador is watching from the hallway, the door stays closed. If your toddler is napping, we keep the banging quiet. That matters just as much as getting the refrigerant charge right.

Common Lennox HVAC Problems We Solve in New Braunfels
Lennox builds solid equipment, but New Braunfels puts specific stress on it. Here are the failures we see most often in this city.
- iComfort communication errors. Lennox iComfort thermostats can lose communication with the outdoor unit after a power surge or firmware glitch, leaving the system stuck in a lockout cycle. We see this regularly in New Braunfels, where thunderstorms roll off the Balcones Escarpment and flicker the grid. The fix is usually a re-pair and firmware check, though a fried control board needs an OEM replacement.
- Inverter board failures on Signature Series units. Variable-capacity inverter boards on XC25 and XC20 systems can fail in high-humidity conditions, particularly near the Comal and Guadalupe rivers. Moisture intrusion and electrical spikes are the usual culprits. We replace these with genuine Lennox OEM boards so the variable-capacity behavior stays factory-correct.
- Capacitor failures during heat waves. Prolonged heat puts high amp draws on condenser capacitors, especially on 5 to 10 year old Merit series units with dirty coils. New Braunfels gets weeks of triple-digit afternoons, and a dead capacitor is one of the most common no-cool calls we run in the older neighborhoods downtown.
- Frozen evaporator coils from clogged condensate drains. Lint, pet dander, and dust clog condensate drains faster in tightly sealed new construction homes east of I-35, where fresh air intake is limited. A clogged drain backs up water, the coil freezes, and the house gets warm. We clear the drain and check airflow so it does not happen again in three months.
- Undersized builder-grade installs. Volume builders in New Braunfels master-planned communities sometimes install the smallest Lennox Merit unit that meets code, not the size that actually handles a Texas Hill Country cooling load. When an August afternoon hits, those units run nonstop and still cannot hold 74 degrees. We can assess the load, and often the answer is better airflow settings or a properly sized replacement.
Lennox Service in New Braunfels: What Local Conditions Mean for Your Equipment
New Braunfels sits right on the Balcones Escarpment, and that geography creates a humidity profile that is measurably different from even nearby San Antonio. Summer humidity in the river valley often runs 10 to 15 percent higher because the Comal and Guadalupe hold moisture in the air. For a Lennox owner, that means one thing: your system’s dehumidification settings matter as much as its temperature settings. We always check blower speed on Lennox variable-speed air handlers here. At the factory default, many systems move air too fast to pull moisture out, leaving a house at 74 degrees but feeling sticky and warm. When we set the blower profile correctly, the same system can drop relative humidity by 10 points or more. In some homes, particularly larger ones in Gruene or River Tree, we recommend a whole-home dehumidifier paired with a Lennox variable-speed air handler. The system runs less, the air feels better, and the house does not smell like a damp basement in July.
We were called to a Lennox XC25 in the River Tree subdivision just east of I-35 not long ago. The homeowner’s iComfort thermostat showed a communication error and the outdoor unit would not start. Our tech found a failed inverter board from a power surge, replaced it with a genuine Lennox OEM board, re-paired the thermostat, and verified the dehumidification setpoints for river valley humidity. The system was back to full variable-capacity cooling within the hour.
Lennox Models & Products We Service in New Braunfels
We service the full Lennox range in New Braunfels, including the Merit Series like the 13ACX, ML14XC1, ML180, and ML296V, the Elite Series like the EL16XC1, EL296V, and EL18XPV, and the Signature Collection including the XC25, XC20, SLP98V, and SL18XC1.

We keep common Lennox parts stocked in our San Antonio shop, which means faster turnaround for New Braunfels repairs, often same-day.

FAQs – Lennox HVAC in New Braunfels
Yes, we see it regularly in New Braunfels, and the triggers here are usually power surges from thunderstorms moving off the Balcones Escarpment or a firmware glitch after a utility outage. The fix is often a re-pair and firmware check, but if the control board or the thermostat itself has failed, we will quote an OEM replacement in writing before any work starts. Call (254) 271-2545 and we will help you sort out whether it is a reset or a real repair.
They can, if the blower speed profile is set correctly for river valley humidity. A Lennox variable-speed air handler paired with an XC25 or EL18XPV can pull dramatically more moisture out of the air than a single-stage system, but only if the technician configures the dehumidification setpoints. Many systems in New Braunfels are left at factory defaults that move air too fast, which defeats the purpose. We check and adjust those settings on every Lennox variable-speed service call. If your home still feels sticky, ask us about a whole-home dehumidifier.
Lennox has issued heat exchanger-related service bulletins and recalls on certain older furnace models, and the responsible approach is to have your specific unit inspected rather than assume the worst. During a tune-up, we visually inspect the heat exchanger for cracks and corrosion, and we will tell you honestly if the unit is safe to run, needs a repair, or should be replaced. If you have an older Lennox furnace in New Braunfels, call (254) 271-2545 and our Furnace Repair in New Braunfels team will schedule an inspection.
It is possible. Volume builders in New Braunfels master-planned communities sometimes install the smallest unit that meets code instead of one sized for the actual cooling load of a large, tightly built home with afternoon sun exposure. But before we recommend replacement, we check airflow, refrigerant charge, and blower settings, because sometimes the problem is a duct issue or a bad capacitor, not the unit’s size. If the unit is genuinely undersized, we will quote a properly sized Lennox replacement with a written fixed price. Call (254) 271-2545 for a free assessment.
Yes, it matters more than most homeowners realize. Many homes in New Braunfels sit on expansive clay soils that swell and shrink with moisture, which can shift concrete pads and put stress on refrigerant lines and electrical connections. An unlevel outdoor unit can cause oil return problems in the compressor and premature wear. We re-level units and in some cases install flexible mounting or vibration pads that accommodate ongoing soil movement. If your Lennox condenser is sitting tilted, call (254) 271-2545 and we will get it set right.
