In San Antonio's dry, dusty climate, you should change your HVAC air filter every 30-60 days during peak usage seasons (summer and winter), rather than the typical 90-day recommendation. San Antonio's environmental conditions create challenges including dust accumulation that restricts airflow, high usage periods when summer temperatures reach triple digits, and seasonal pollen increases in spring. We recommend monthly filter inspections. A clean filter can improve energy efficiency by 15% and extend your system's lifespan.

The most common culprit in San Antonio: indoor coils become coated with dust, mold, mildew, and debris, preventing proper condensation and dehumidification. Additional factors include oversized AC units that cool quickly but shut off prematurely, and improper thermostat settings. Warning signs include condensation on windows, musty odors, cold but clammy rooms, and frequent system cycling. The solution typically involves coil cleaning and proper system sizing.

In San Antonio's demanding climate, professional HVAC maintenance should be scheduled twice yearly — once before cooling season and once before heating season. Spring maintenance (March-April) includes AC system inspection, coil cleaning, refrigerant checks, electrical inspections, and drain line clearing. Fall maintenance (October-November) covers heating system inspection, thermostat calibration, safety verification, and filter replacement. Between professional visits, homeowners should perform monthly filter checks and visual inspections.

Consider replacement if your system is over 10-15 years old, requires frequent repairs, or struggles to handle San Antonio's demanding climate. Key indicators include increasing energy bills despite maintenance, repair costs exceeding 50% of a new system's price, inability to maintain comfort during extreme heat, or systems still using R-22 refrigerant. For a typical 2,000 sq ft San Antonio home, cooling capacity should be 2.5-5 tons, while heating requires 50,000-80,000 BTUs. Professional load calculations are essential for proper sizing.

Critical seasonal tasks include pre-summer professional AC tune-ups, coil cleaning, refrigerant checks, and drain line cleaning. Mid-summer requires monthly filter checks due to high usage, drain pan inspection, and outdoor unit cleaning. Pre-winter involves heating system inspection and thermostat calibration. Year-round, you should check for unusual noises, keep the outdoor unit debris-free, and verify proper airflow. Homeowners can handle filter changes and basic cleaning, but professional service is essential for refrigerant checks, electrical inspections, and coil cleaning.
