Heating Maintenance in Mission, TX and the Rio Grande Valley
Book a Pre-Winter Inspection Today
Heating maintenance gets skipped in the Valley more than any other service we do, and it is easy to see why. The heater sits off from March to December, then gets switched on the first cold night like nothing happened. Frontier Cooling & Heating has been checking Valley heating systems since 2006, from our office on Griffin Parkway in Mission.
We're family-owned and Latino-owned, our technicians are licensed and insured, and we work on most major brands, electric and gas.
If you've been searching heating maintenance near me, call (956) 955-6340. Missed calls get a call back within 5 minutes.
What Heating Maintenance Covers
A heater tune-up is a safety visit as much as a performance one. Heat strips run hot, and gas furnaces burn fuel inside your house, so the checklist is longer than most people expect.
On electric systems that means a heat strip inspection, a heating electrical safety check on the wiring, breakers, and limit switches, and a look at the blower. On gas systems it adds burner cleaning, ignitor & flame sensor cleaning, a heat exchanger inspection, and a flue & vent inspection.
Put together, it is a furnace safety inspection and a tune-up in one visit. Our HVAC maintenance visits cover the cooling side as well.
Why Valley Heaters Need a Pre-Season Check
A heater that sits idle ten months a year collects trouble. Dust settles on the strips and burners. Mud daubers build nests in vents and outdoor cabinets. A limit switch that worked fine last January quietly fails over the summer.
That first-run burning smell is mostly dust, and a heater cleaning before the season cuts it down. A heater inspection also catches the problems nobody wants to find at 11 at night with a cold house.
The best time for a winter heating check up is October or November, before the first cold front around Thanksgiving. Book a heating tune up then and you are not competing with every other house in the Valley on the first cold morning.


Gas Furnace Safety Checks That Matter
If your home has a gas furnace, maintenance is about more than comfort. A cracked heat exchanger or a blocked flue can push carbon monoxide into the house.
Every gas furnace visit includes a gas line leak check at the furnace connections, a gas pressure adjustment if the reading is off, a pilot light & ignition test, and inducer motor lubrication where the motor calls for it. Then comes carbon monoxide testing at the vents and around the furnace.
If we find something unsafe, we show you what we found and explain exactly why before anything else happens. A cracked heat exchanger usually means replacing the furnace, and we will price that honestly. A working CO detector near the bedrooms is still the best backup.
Electric Heater Tune-Up
We clean and inspect the heat strips, test each element and sequencer, and check the breakers and wiring for heat damage.
It heads off the most common no-heat call in the Valley.
Gas Furnace Tune-Up
Furnace cleaning, plus a furnace inspection of the burners, the ignition, and the safety controls.
This is the visit that keeps a gas furnace safe to run all winter.
Heat Pump Heating Check
A heat pump heats with the same outdoor unit that cools. We test the defrost cycle, the reversing valve, and the backup strips.
That keeps it from leaning on the strips all winter. More on heat pumps.
Thermostat and Airflow Check
We confirm the thermostat calls for heat at the right temperature, check the filter, and measure the air at the vents. A clogged filter is the fastest way to trip a heat strip limit switch.
If your thermostat is due, ask about a smart thermostat.
Careful, Plain-Spoken Heating Tune-Ups
A tune-up is only worth booking if it is done carefully. This is how ours go.
Safety Before Comfort
Every visit starts with the checks that protect your family: electrical safety, limit switches, and on gas systems, combustion and venting.
What We Found, Shown to You
If something is worn, we show you the part and explain what happens if it is left alone. Repairs are quoted before any work, and the choice is yours.
Most Brands, Electric and Gas
We service most major brands and a wide range of system ages, from heat strips in an older air handler to newer gas furnaces.
Repairs When You Need Them
If the tune-up turns up a failing part, our heating repair technicians can quote it and get it scheduled.

Appointments Seven Days a Week
We service within 24 hours of your call, with same-day and next-day appointments when available. Hours run 7:30am to 7pm on weekdays and 8am to 5pm on weekends.
Access to the Furnace and Thermostat
Clear a path to the furnace or air handler in the closet, attic, or garage, plus the thermostat, and the outdoor unit if you have a heat pump.
A Clear Picture Before Winter
Before we leave, you know what we checked, what we cleaned, and anything that needs attention before the cold arrives.
Heating Checks Through the Cowboy Kool Club
Members of our Cowboy Kool Club get routine tune-ups and priority scheduling, so the heater gets its yearly check along with the AC.
Furnace Tune Up Cost and Club Pricing
We do not post a flat furnace tune up cost here, because it depends on the system and on current offers. Call and we will give you the price for a one-time visit.
For most homes the better value is a maintenance membership that covers heating and cooling together. Check our current specials too.

Heating Maintenance FAQs
How often should a heater be serviced in the Rio Grande Valley?
Heater maintenance once a year, in the fall, is enough for most Valley homes. A heat pump works all year, heating and cooling, so it should be checked in the spring and the fall.
Do electric heaters need a tune-up?
Yes. A heater tune up on an electric system checks the heat strips, sequencers, limit switches, and wiring. Those parts run hot and cause most of the no-heat calls we see here.
Do you check gas furnaces for carbon monoxide?
Yes. On every gas furnace visit we check for carbon monoxide at the vents and around the unit, along with the heat exchanger and venting. We still recommend working CO detectors in the home.
What is included in a winter furnace tune-up in Mission?
On gas furnaces: the burners, ignition, heat exchanger, venting, and electrical. On electric systems: the heat strips, wiring, and limit switches. We run the system through a full heating cycle before we leave.
Can maintenance lower my heating bill?
Clean strips, a clean filter, and a well-adjusted furnace waste less energy. In a climate where the heat runs a few weeks a year, the bigger payoff is safety and not getting caught without heat on the coldest night.
