HVAC Repair San Jose CA | Call Sandium Heating and Air Conditioning

Our installation process begins with a detailed engineering analysis, drawing on over 20 years of experience and founder Michael's background in building performance. We don't just swap units; we assess your home's specific layout, insulation, and airflow to design a system that operates efficiently in our local climate. This tailored approach, focused on proper sizing and ductwork, helps prevent future issues and ensures your system delivers optimal comfort and energy savings for years to come.

During our maintenance visits, we thoroughly inspect and clean both the air filters and evaporator coils, which are common trouble spots in our area. We explain how San Jose's dust and pollen can accelerate clogging and show you how to check filters between visits. For dirty coils, our technicians perform a careful cleaning to restore efficiency and prevent strain on the system, which is a key part of our preventative maintenance strategy to avoid costly repairs and maintain good indoor air quality.

Absolutely. With a background in commercial building performance contracting and energy analysis, we specialize in evaluating older systems for upgrade potential. We can often integrate modern, high-efficiency heat pumps or furnaces with your existing ductwork and recommend eco-friendly repairs or add-ons like ventilation systems. Our goal is to provide a clear, practical upgrade path that improves your comfort and reduces energy use, tailored to your San Jose home's needs.
