Certified HVAC Repair in San Antonio, TX 78254 - Alexander Services AC & Heat

During extreme heat, your AC works its hardest, which can overwhelm older systems or reveal underlying issues like low refrigerant or a failing compressor. At Alexander Services, our expert repair technicians diagnose the root cause quickly and perform reliable repairs to restore your cool air. We also offer installation services for energy-efficient systems better suited to handle our intense summers, providing a long-term solution.

Our comprehensive maintenance service specifically addresses San Antonio's humid climate, which is a leading cause of clogged drains. We thoroughly clean and flush the condensate drain line and pan, check the drain trap, and ensure the system's safety switch is working. This preventative step is crucial to avoid water damage and unexpected system shutdowns, keeping your AC running smoothly all season.

If you're facing frequent repairs, especially for major components during our hot summers, or if your system is over 10-15 years old and inefficient, replacement is often more cost-effective. A new, properly sized HVAC installation from Alexander Services provides greater reliability during heatwaves, significantly lowers energy bills, and improves indoor air quality and comfort for your San Antonio home.
