Frequently Asked HVAC Questions
Everything you need to know about air conditioning repair, system replacements, energy efficiency, maintenance schedules, and warranties in Houston, Texas.
Common indicators include: warm or weak airflow, unusual grinding or squealing noises, pungent or burning odors, frequent on-and-off cycling (short cycling), ice accumulating on the evaporator coils, water pooling around the indoor drain pan, and unexpected spikes in your monthly electricity bill.
We offer 24/7/365 emergency dispatch across all of Houston and Harris County. For active cooling failures during extreme heat, our certified mobile technicians arrive within 60 minutes with fully stocked service vans ready to resolve the breakdown on the spot.
A good rule of thumb is the $5,000 rule: multiply the age of your system by the repair cost. If the result exceeds $5,000 (e.g., a 10-year-old system needing a $700 repair = $7,000), replacement is typically more economical. Also, systems using phased-out R-22 Freon or having recurring compressor failures should be replaced with modern high-SEER2 equipment.
In Texas (DOE Southeast Region), the legal minimum standard is 14.3 SEER2 (equivalent to 15 SEER). For optimal return on investment in Houston's intense cooling climate, we recommend 16 to 18 SEER2 multi-stage or variable-speed systems, which provide superior humidity removal and up to 35% lower electric bills.
Your system should be professionally serviced twice a year: once in the spring for the cooling system and once in the fall for the heating equipment. Regular tune-ups clean coils, calibrate thermostats, tighten electrical connections, and prevent 80% of unexpected summer breakdowns.
Standard 1-inch pleated filters should be replaced every 30 to 60 days. If you have pets, allergies, or run your system continuously during the peak July–August Texas heat, check filters every 30 days. High-capacity 4-inch to 5-inch media filters typically last 6 to 9 months.
Simple repairs such as replacing a dual run capacitor, contactor, or clearing a clogged condensate drain line generally cost between $150 and $350. Medium repairs like fan motor replacement or refrigerant leak repairs range from $350 to $850. Major repairs like compressor replacements range higher.
