OAR Heating & Air: Expert HVAC Services Serving Stockton, CA 95204

Common signs include visible dust blowing from vents, a persistent musty odor, or an unexplained increase in allergy symptoms among household members. In our local climate, systems work hard and can accumulate dust and debris. We offer a thorough inspection and can recommend a cleaning and sanitization service to improve your home's air quality and system efficiency.

Our maintenance service is designed to keep your system running reliably and efficiently. We perform a comprehensive check, including inspecting electrical connections, cleaning coils, checking refrigerant levels, lubricating moving parts, and clearing the condensate drain line—a common source of leaks in our area. Regular maintenance can prevent costly repairs and extend the life of your system.

An improperly sized system is a frequent issue we see. A unit that's too large will short-cycle, turning on and off rapidly, which leads to uneven temperatures, higher humidity, and increased wear. One that's too small will struggle to keep up during our hot summers or chilly winters, driving up energy bills. We perform detailed load calculations for every installation to ensure your new system is correctly matched to your home's layout and insulation for optimal comfort and efficiency.
