All Star Heating & Air: Certified HVAC Services Serving San Marcos 92076

Signs include reduced cooling performance, longer run times, higher energy bills, and visible rust or pitting on the coil fins. In San Marcos, salty coastal air can accelerate this. Our technicians perform detailed inspections, clean the coils thoroughly, and can apply protective coatings to help prevent future corrosion and maintain system efficiency.

Common indicators are uneven heating or cooling between rooms, excessive dust, whistling sounds from ducts, and unexpectedly high utility bills. We use specialized diagnostic tools, like blower door tests and smoke pencils, to pinpoint leaks in your ductwork. Our repairs involve sealing leaks with professional-grade mastics and tapes, which improves airflow, enhances comfort, and boosts your system's overall efficiency.

Absolutely. Duct leaks force your system to work harder to heat or cool your home, wasting conditioned air. Corroded coils reduce heat transfer efficiency, making the system run longer. By addressing both issues, we restore your HVAC system's designed efficiency. This directly translates to lower monthly energy bills and reduces strain on your equipment, helping it last longer in our local climate.
