5 HVAC Mistakes San Antonio Homeowners Keep Making

Common HVAC issues in San Antonio often stem from the region's extreme summer heat and high humidity, which force cooling systems to run continuously for months. These environmental stressors frequently lead to component failure, reduced energy efficiency, and indoor air quality concerns if maintenance is neglected.

  • Condensate drain clogs: San Antonio’s high humidity levels cause air handlers to produce significant moisture, which often leads to algae growth and clogs in drain lines. If left unchecked, this water can back up and cause ceiling damage in homes across neighborhoods like Alamo Heights or Stone Oak.
  • Evaporator coil corrosion: The combination of persistent humidity and local air quality factors can lead to formicary corrosion on evaporator coils. This degradation creates tiny pinhole leaks that allow refrigerant to escape, significantly reducing the cooling capacity of your unit during 100°F+ summer peaks.
  • Overworked compressor motors: During prolonged heat waves, San Antonio cooling systems face extreme thermal stress, which can cause compressor motors to overheat and fail prematurely. Regular cleaning of outdoor condenser coils is essential to help the unit shed heat efficiently and prevent motor burnout.
  • Ductwork air leaks: Fluctuating temperatures and attic heat in San Antonio can cause duct sealant to crack or peel over time. Leaky ducts force your HVAC system to work twice as hard to maintain comfortable temperatures, leading to higher utility bills and uneven cooling throughout your home.
  • Electrical contactor pitting: Frequent cycling during the long cooling season causes the electrical contactors in your outdoor unit to wear down faster. If these components become pitted or stuck, the system may fail to start or run continuously, potentially damaging the compressor.

If your system makes rattling sounds or blows warm air, turn it off immediately to avoid further damage to the compressor. Contact a licensed professional to inspect the unit before attempting to restart it.
