HVAC Services San Jose CA | Call Controlled Air Systems

Our installation process begins with a detailed assessment of your home's layout, insulation, and your family's comfort needs. We then recommend a system, such as an energy-efficient heat pump or ductless system, that's properly sized for optimal performance and efficiency in our local climate. Our factory-authorized technicians handle the entire installation, including ductwork if needed, ensuring it meets all local codes. We focus on a clean, precise setup that delivers reliable heating and cooling for years to come.

In San Jose's climate, a common culprit is a dirty evaporator coil inside your air handler, which restricts airflow and reduces cooling capacity. Another frequent issue we see is corrosion on the outdoor condenser coil, often accelerated by local environmental factors and sprinkler overspray. Our technicians are trained to diagnose these specific problems quickly. We perform thorough cleanings using appropriate methods and, if corrosion has caused leaks, we use factory-authorized parts for repairs to restore your system's efficiency and protect your investment.

Yes, we offer tailored maintenance agreements designed to keep your HVAC system running smoothly and efficiently.

This proactive approach helps San Jose homeowners avoid the inconvenience and cost of emergency breakdowns, especially during peak heating and cooling seasons.
