Our shop sits on West Griffin Parkway, two minutes off the 83, so when you call for HVAC Repair in Mission, the truck does not have far to go. We have answered these calls since October of 2006, and after almost two decades of working on homes from the older streets south of Conway Avenue out to the newer builds in Sharyland, we know how systems fail here. They quit on the hottest afternoon. They quit two weeks after the last cool morning in February. They quit because nobody changed the filter through five months of caliche dust off Bryan Road. That is where we come in.
Frontier Cooling & Heating is the same family operation Joe Villegas started a few miles from here in 2006. Same standards he set then. When the call comes in for HVAC Repair, the technician is one of ours, in a marked van, with license number TACLB17844C posted on the door.
How We Approach HVAC Repair in Mission
HVAC Repair is not a one-size job. A 14-year-old condenser running on a packed coil behaves nothing like a three-year-old variable-speed system throwing a control board fault. We start the same way every time. We listen to what the homeowner has noticed. We walk the system from the thermostat to the disconnect. We read the actual data off the equipment before we open a parts bag.
As experienced hvac contractor working both residential and commercial properties, our technicians know the major brands sold in the Valley over the past twenty years. Carrier, Trane, Lennox, Goodman, Rheem, Daikin, Mitsubishi. Most calls we run in Mission start with the same complaint, "ac not cooling," and finish in three buckets. Refrigerant problem. Electrical problem. Airflow problem. Knowing which bucket a system is in before pulling parts is the difference between a fast fix and an expensive guess. If you searched "hvac repair near me" and landed here, the next step is a call to
956-955-6340.
Featured Services
Air Conditioning Repair Built for Mission Summers
Mission homes lean on the AC eight months of the year. After Memorial Day the system runs fourteen-hour days through September. We handle ac repair across the full range of issues that kind of load creates. Ac compressor repair when the unit hums and refuses to start. Ac leak repair on copper lines that have been weeping a quarter-pound of refrigerant per season. Central ac repair on the indoor coil and blower. Emergency ac repair when the house is climbing past 85 with kids or older parents inside. Air conditioning repair on the original condensers planted around the Madero Road and Inspiration Road corridor is most of our August workload.
Furnace Repair and Heat Pump Repair for Cold Snaps
Mission gets maybe ten true cold mornings a year, plus the freeze the Valley still talks about from February 2021. Heating repair becomes urgent in a hurry when those mornings hit. We service gas furnaces, electric furnaces, and heat pump systems. A lot of our furnace repair calls in Mission are systems that ran fine last winter but sat ten months untouched and refuse to fire on the first cold night. Heat pump repair is growing too, especially on the newer builds north of Mile 2, where heat pumps are the default install.
Air Duct Repair and Ductwork Repair
A perfect condenser still cannot cool a house through a leaking duct system. A surprising number of Mission homes built between the late 1990s and the mid-2000s have flex duct in the attic that has slumped, separated at takeoffs, or been chewed by rodents. Air duct repair is some of the most cost-effective work we do, and ductwork repair often solves the "one room never cools" problem the homeowner has lived with for years.
Commercial HVAC Repair on Mission Properties
The strip centers along Conway, the medical offices near Mission Regional Medical Center, and the restaurants around the Junction at the 83 run on rooftop units that take a beating. We provide commercial hvac repair, commercial ac repair, and commercial heating repair as part of our broader commercial hvac service, with after-hours work available so a dining room does not have to close during lunch rush.
Why Mission Homeowners Call Frontier
We are local. The headquarters at 1812 W Griffin Parkway is not a satellite of a chain. Joe started the business in this city. The dispatchers know the streets. The techs grew up on them. When someone calls and says they live "two streets behind the Stripes by the Boys and Girls Club," the person answering the phone already knows where that is.
We are a certified hvac contractor, fully licensed and insured under TACLB17844C, with NATE-certified techs on the roster. We do not lead with sales. The technician's job on an HVAC Repair call is to fix what is broken and tell the homeowner the truth about the rest. If a 16-year-old condenser will cost more to repair than replace, we say that and quote both options. If a repair holds for another two or three seasons, we say that too.


Key Benefits of Professional HVAC Repair in Mission
A real diagnosis saves money. Most "the AC quit" calls in Mission are not catastrophic. A bad capacitor, a failed contactor, or a clogged condensate drain on the indoor coil is a fraction of the cost of the compressor most homeowners are bracing for. A real hvac system repair starts by ruling those out.
Repaired systems pull less power. The Mission electric bill in July is enough of a hit without a struggling condenser drawing extra amps because the blower is moving half the air it should. After a real HVAC Repair, run times shorten and the bill drops.
Lifespan extends. Equipment caught early, before the compressor starves on low refrigerant or the motor seizes from a frozen coil, holds another five to seven years on average. That delay matters when a replacement system runs five figures.
Indoor air quality improves. Half the comfort complaints we get are not about temperature; they are about humidity. When the system runs the right cycle length, it pulls moisture out of the house and the 78-degree thermostat setting starts to feel like 75 again. Dehumidifier repair on whole-house units and thermostat repair on systems that short-cycle both play into this. A repaired system is also one you can stop worrying about. That is what most "hvac contractor near me" searches are really looking for.
