Warm, Reliable Heat for the Rio Grande Valley
Furnace Installation, Repair & Maintenance
When cool RGV nights arrive, your furnace should start cleanly, heat evenly, and run safely. Treviño Repairs installs, repairs, and maintains gas furnaces (80% & 90+ condensing) and electric furnaces/air handlers with heat strips—sized correctly, vented and wired to code, and commissioned for quiet, efficient comfort. We review load/airflow, check ducts and gas/electrical, present clear AFUE/HSPF2/SEER2 options, and deliver neat workmanship with straightforward pricing for your home or business.
End-to-End Service—RGV Wide
Services for Furnaces
We plan, install, repair, and maintain furnaces with safety, efficiency, and code compliance in mind. After a focused assessment, we give you options (repair vs. replace, single- vs. two-stage, variable-speed), coordinate permits when required, protect the work area, and finish with a tidy, inspection-ready install.
Installation & Replacement
- Gas furnaces (80% & 90+% condensing), matched coils for AC/heat pumps
- Electric furnaces/air handlers with heat strips (right-sized kW)
- Variable-speed/ECM blowers, two-stage & modulating options
- Smart thermostat wiring/adapters; surge protection (as appropriate)
Repairs & Diagnostics
- No-heat, short-cycling, or frequent lockouts
- Hot-surface igniters, flame sensors, pressure switches, inducer motors
- Control boards, relays, transformers, capacitors, thermostat/sensor wiring
- Blower motors/wheels, limits/rollouts, drain/condensate faults (90+)
Maintenance & Tune-Ups
- Burner cleaning/inspection, temperature-rise verification
- Filter/airflow/static-pressure checks; blower amp draw
- Condensing furnace trap/condensate service and vent review
- Safety tests and documentation
AFUE, 80% vs. 90+% & Airflow—What Matters Most
AFUE measures furnace efficiency—the percentage of fuel turned into usable heat. 80% furnaces vent via metal flue and can be cost-effective where vent routes are simple. 90+% condensing furnaces reclaim more heat, vent with PVC, and produce condensate that must be drained correctly; they typically lower fuel use. Whichever you choose, airflow makes or breaks comfort and reliability: undersized returns or dirty coils cause high temperature rise, limit trips, and early parts failure. We check static pressure, set blower speeds, and verify temperature rise so your RGV home gets steady heat without stress on the equipment.
Know the Warning Signs in the Rio Grande Valley
When to Service or Replace Your Furnace
No heat, frequent short-cycling, burner not lighting, a blower that won’t run or won’t stop, burning or gas odors, rattling/grinding noises, water under a 90+ furnace, soot/rust at the burner or flue, or rooms that never reach setpoint are all red flags. Rising winter bills, repeated igniter/flame-sensor failures, or an older unit (often 15–20 years for furnaces) also point to upgrade time. Treviño Repairs can isolate the fault, perform a clean repair, or size and install a right-fit replacement for your RGV home or business. If you smell gas, leave the area and contact your gas utility or emergency services first.

What Our Customers Are Saying
Furnace Questions, Answered
Straightforward answers before you book—symptoms, costs, fixes.
80% or 90+%: which should I choose?
Depends on venting path, upfront cost, and fuel savings. 90+% furnaces use PVC venting and a condensate drain and typically lower fuel use; 80% can fit simpler vent routes. We’ll compare payback and feasibility in your home.
Why does my furnace keep shutting off after a few minutes?
Often high temperature rise or a limit trip from restricted airflow (dirty filter/coil, undersized returns) or a pressure-switch/venting issue. We check airflow, safeties, and combustion.
I replace the igniter or flame sensor every year—why?
Underlying issues like contamination, over-firing, or poor grounding can shorten life. We verify gas pressure, burner alignment, and temperature rise to stop repeat failures.
Do I need a new thermostat with a new furnace?
Not always. We reuse your stat if compatible; for two-stage or variable-speed models, a smart or compatible thermostat may unlock better comfort.
What maintenance should I plan for?
Annual service: filter/airflow checks, burner/ignition inspection, electrical tests, temperature-rise verification, and condensate/venting checks on 90+%. We label schedules and provide a simple report.
