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 South and Southwest Houston corridor — Meyerland, Braeswood Place, Westbury, Braeburn, Willow Meadows, and the communities connecting Houston's inner loop to the suburbs further south and west.
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
Houston's Gulf Coast climate hits South Houston hard. The combination of sustained summer heat, high humidity, and the urban heat island effect means AC systems in this area work harder than almost anywhere in the country — with heat indexes above 105°F common from May through September and cooling seasons that run nine months or more.
We Know Houston Homes
South and Southwest Houston includes a remarkable range of housing: mid-century ranch homes in Meyerland and Braeswood (many rebuilt or renovated after flooding), established 1960s–70s neighborhoods in Westbury and Braeburn, and the NASA-era communities in the Clear Lake corridor. Each era and neighborhood has its own HVAC challenges — we've worked in them all.
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.
