Fast, Reliable Cooling in the Rio Grande Valley
Air Conditioner Repair & Troubleshooting
When your AC blows warm air, short-cycles, leaks water, trips a breaker, or just can’t keep up with RGV heat, Treviño Repairs finds the real cause and fixes it the right way. We service central AC and ductless mini-splits, verify power and controls, check airflow and drain performance, and test the refrigeration circuit to manufacturer specs. Expect clear options and pricing, clean workmanship, and a neat finish for your home or business.
Cool Air, Done Right—RGV Wide
Services for Air Conditioner Repair
Treviño Repairs starts with targeted diagnostics to separate electrical, airflow/drain, and refrigerant issues, then performs a clean, code-compliant repair. We test breakers/disconnects, capacitors, contactors, motors, and controls; measure static pressure, inspect filters/ducts/coils, and clear condensate lines; and verify charge using superheat/subcooling instead of guesswork. You’ll get options that fit your system and budget—no band-aids that won’t last.
We service:
- Central AC & heat pumps (cooling mode) and ductless mini-splits
- Capacitors, contactors/relays, fuses, and thermostat/control issues
- Blower & condenser fan motors, belts, fan blades, and bearings
- Frozen coils/ice-ups, restricted metering devices (TXV/orifice)
- Refrigerant leaks: leak checks, repairs, and charge verification
- Dirty or damaged evaporator/condenser coils (cleaning/repair)
- Condensate problems: clogged drains, float switches, pans, pumps
- Duct restrictions/leaks, weak airflow, hot/cold spots
- Performance checks: delta-T, static pressure, superheat/subcooling
- Light commercial package/rooftop units (as applicable)
AC Repair vs. Tune-Up — What’s the Difference?
A repair targets a fault that’s stopping cooling now—failed capacitor or motor, iced coil, control issue, clogged drain, or a verified refrigerant leak. We replace/repair the faulty part, correct the cause, and verify performance. A tune-up is preventive: coil cleaning, drain service, filter/airflow checks, electrical testing, and performance measurements to keep efficiency up and breakdowns down. If your system isn’t cooling, start with repair diagnostics; if it’s running but underperforming or due for seasonal care, schedule a tune-up.
Know the Warning Signs in the Rio Grande Valley
When to Schedule AC Repair
Warm or uneven air, low airflow, ice on the refrigerant lines, water around the air handler, frequent on/off short-cycling, breaker trips, new grinding/buzzing noises, musty or burning odors, rising energy bills, or a thermostat that can’t reach setpoint are all red flags. Treviño Repairs can isolate the issue—electrical, airflow/drain, or refrigerant—then restore safe, reliable cooling for your RGV home or business.
What to Expect with Treviño Repairs
Our Air Conditioner Repair Process
Assess & Triage. Confirm symptoms, model details, and recent work; verify thermostat settings and basic power.
Protect & Prep. Shoe covers, drop cloths, safe disconnects, and access panels opened neatly.
Electrical & Controls. Test breakers/fuses, capacitors, contactor, motors, wiring, and control board/thermostat operation.
Airflow & Drain. Check filter and coil condition, blower speed/static pressure, duct restrictions/leaks; clear and flush the condensate line and verify float switch.
Refrigerant Circuit. Measure superheat/subcooling, scan for leaks when indicated, and confirm metering device operation—no guessing on charge.
Repair & Verify. Replace failed components, clear blockages, correct wiring, recharge only after repairs when needed, and verify delta-T and stable operation.
Clean Up & Walkthrough. Tidy the area, review findings and prevention tips (filters, drain maintenance), and provide clear next-step options.
Real Stories. Real Results.
What Our Customers Are Saying
Air Conditioner Repair Questions, Answered
Straightforward answers before you book—symptoms, costs, fixes.
Why is my AC blowing warm air?
Common causes include a failed capacitor/contactor, dirty coil or filter restricting airflow, a clogged drain triggering a float switch, or a refrigerant issue. We test each area so you’re not paying for guesses.
Do I need refrigerant?
Only if there’s a verified leak. We check superheat/subcooling and perform leak diagnostics when indicated; adding refrigerant without finding the leak is a short-term fix.
The unit is icing up—what does that mean?
Ice points to airflow problems (dirty filter/coil, weak blower/low speed) or refrigerant/ metering issues. We thaw safely, correct the cause, and verify proper charge and airflow.
How long do repairs take and what will it cost?
Most common parts (capacitors, contactors, some motors) are same-day. After diagnostics, we give an upfront quote before any repair.
How can I prevent future breakdowns?
Change filters regularly, keep outdoor coils clear of debris, and schedule seasonal service for coil/ drain maintenance and electrical checks—especially important in RGV heat and humidity.
