Preventitive Maintenance
Scheduled Maintenance to Keep Your System Running at Its Best.
The most expensive HVAC repairs are the ones that could have been caught early. Regular maintenance keeps your furnace and air conditioning system running efficiently, extends equipment life, and catches small issues before they turn into big ones. We offer scheduled maintenance for residential and light commercial properties across Sonoma, Marin, and Napa County. Every tune-up includes a full inspection of your equipment, cleaning, safety checks, and an honest report on the condition of your system. No contracts required, no pressure, just reliable service on a schedule that works for you.

Comfort isn’t luck, it’s built. At Legacy Heating & Air, we design, install, and repair systems with precision, from accurate load calculations to properly engineered ductwork. The result is consistent comfort, lower energy waste, and a system that finally performs the way it should.

When your system breaks down, we fix it fast and fix it right. We accurately diagnose furnace and AC issues, use quality parts, and make sure everything is running properly before we leave. No guesswork, no shortcuts, just reliable repairs you can trust.

Most comfort issues start in the ductwork. We redesign and replace ducts using proper Manual D calculations to eliminate leaks, improve airflow, and balance temperatures throughout your home. Ideal for older homes, difficult layouts, or systems that never felt right.
Furnace & a/c Replacement
Full system replacements built around your home, not a one-size-fits-all unit. We use proper Manual J load calculations to size your system correctly, improving comfort, efficiency, and long-term performance. Lower energy bills, better airflow, and a system that actually keeps up.
