AC & Heating Tune-Up in Alvin, Friendswood, Pearland & the Greater Houston Area

Annual AC & Heating Tune-Up Service for Greater Houston Homes

In the greater Houston area, your air conditioning system works harder than almost anywhere in the country — up to 9 months per year in some of the most demanding heat and humidity in the United States. Annual preventive maintenance is the single best thing you can do to prevent a breakdown on the hottest day of August, extend the life of your equipment, and keep your energy bills under control. Mabry's Air Conditioning & Heating has been providing thorough, honest maintenance tune-ups for Alvin, Friendswood, Pearland, and surrounding Houston-area homes since 1986.

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 (Houston humidity makes this critical)
• 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 system for the Houston winter season:

• 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

Why Houston-Area Homes Need Annual Maintenance

The Gulf Coast climate around Alvin, Friendswood, and Pearland creates specific maintenance challenges that homeowners in drier climates don't face:

• High humidity clogs condensate drains quickly — a clogged drain can overflow and cause water damage or mold
• Extended run times (9+ months of cooling) wear capacitors, contactors, and motors faster than national averages
• Coastal air accelerates corrosion on outdoor condenser units
• Heating systems that sit dormant for 6–9 months are more likely to fail on the first cold day

Catching Problems Before They Become Emergencies

The most common AC emergencies we see — failed capacitors, low refrigerant, clogged drains — are almost always detectable during a routine maintenance visit. A $99–$150 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.
