ST Heating and Air Conditioning - San Diego's Trusted HVAC Services

Owner Sinan Tobchi holds an MSc in Aerospace and Mechanical Engineering from USC, which informs our scientific design process. We focus on creating energy-efficient systems that reduce electricity consumption while ensuring reliable performance in San Diego's climate. Our installations prioritize longevity and comfort, backed by a parts and labor guarantee.

In San Diego's coastal environment, salt air can accelerate condenser coil corrosion. During maintenance or repairs, we inspect coils for early signs of damage, clean them properly to prevent buildup, and recommend protective coatings or strategic placement to extend system life. This proactive approach helps avoid costly failures and maintains efficiency.

Our maintenance service covers comprehensive checks tailored to local needs, including inspecting air handlers for fan issues common in older systems, testing refrigerant levels, and ensuring components are clean and functional. We focus on preventing problems before they arise, which helps improve energy efficiency and system reliability year-round. Free diagnostics are included with every visit.
