AC & Heating Maintenance in Houston, TX, Prevent Breakdowns, Extend System Life
Annual AC tune-up and heating maintenance to prevent costly breakdowns, lower energy bills, and extend equipment life. Trusted by homeowners in Houston since 1986.
AC & Heating Tune-Up for Houston Homeowners
In Houston, your air conditioning system works harder than almost anywhere in the country, up to 9 months per year under Gulf Coast heat and humidity. Annual preventive maintenance is the single best thing you can do to prevent a breakdown on the hottest day of August and keep your energy bills under control. Mabry's serves the Clear Lake area of Houston, Clear Lake City, the Space Center and NASA-area neighborhoods, and Southeast Houston's 77058, 77059, and 77062 zip codes that were annexed into the city decades ago but kept their Clear Lake identity.
What Our AC Tune-Up Includes
Our spring AC tune-up is a comprehensive inspection and tune-up of your entire cooling system:
- Refrigerant level check, verify proper charge (low refrigerant = poor cooling and compressor damage)
- Capacitor testing, capacitor failures are the #1 cause of AC breakdowns in Houston summers
- Contactor inspection, worn contactors cause compressor and fan motor failure
- Condenser coil cleaning, dirty coils reduce efficiency and cause overheating
- Evaporator coil inspection, check for ice buildup, dirt, and refrigerant issues
- Condensate drain flush, prevent clogged drains and water damage (Gulf Coast humidity makes this critical for Houston homes)
- Blower motor and belt inspection, ensure proper airflow throughout your home
- Thermostat calibration, confirm your system responds accurately
- Electrical connections and wiring check, loose connections cause failures and safety hazards
- Filter inspection and replacement guidance
- Overall system performance assessment, temperature differential check
What Our Heating Tune-Up Includes
Our fall heating tune-up prepares your Houston home's heating system for winter:
- Heat exchanger inspection, critical safety check for gas furnaces (cracked exchangers can leak carbon monoxide)
- Burner and igniter inspection, ensure reliable ignition on first use
- Flame sensor cleaning, dirty sensors cause nuisance shutdowns
- Gas valve and pressure check, verify safe, proper gas flow
- Heat pump reversing valve check, ensures proper heating mode operation
- Electrical components and wiring inspection
- Thermostat calibration
- Airflow and ductwork assessment
- Overall system safety check
Houston's Climate and Your HVAC System
This corner of Houston sits right by Galveston Bay, so its Gulf Coast climate is relentless, sustained summer heat, year-round humidity, and salt-influenced air that's harder on outdoor equipment than it is inland. AC systems here run nine months a year with heat indexes above 105°F common from May through September.
We Know Houston Homes
The Clear Lake area of Houston grew up around NASA's Johnson Space Center, so much of the housing in the 77058, 77059, and 77062 zip codes dates to the aerospace boom of the 1960s through 1980s. Many of these well-built homes still run original single-stage equipment and older ductwork, prime territory for repair, replacement, and efficiency upgrades, all of which we handle.
The most common AC emergencies we see in Houston, failed capacitors, low refrigerant, clogged condensate drains, are almost always detectable during a routine maintenance visit. A pre-season tune-up that catches a failing capacitor saves you an emergency service call on a 100°F Saturday in July. Maintenance also keeps your manufacturer's warranty valid on newer systems and can extend equipment life by 3–5 years or more.
