HVAC in Monte Sereno, Sized for Custom Homes
Monte Sereno is one of the smallest cities in Santa Clara County, a quiet residential pocket at the foot of the Santa Cruz Mountains. Its homes tend to be large, custom-built, and set on generous lots, which makes HVAC design more involved than dropping in a one-size-fits-all unit. Modern Air has been repairing and replacing South Bay systems from its Morgan Hill shop since 2009, and we treat each Monte Sereno home on its own terms.
Comfort That Matches the House
In Climate Zone 4, Monte Sereno sees warm summers tempered by the foothills. Multi-story custom homes here often have wings and upper floors that run several degrees warmer than the rest of the house. A single thermostat can’t fix that. Modern Air designs zoned cooling and heating so each part of the home is controlled independently, which keeps comfort even and stops the system from short-cycling to satisfy one hot room.
For many Monte Sereno properties, a high-efficiency heat pump is the natural fit: it handles both heating and cooling, runs quietly, and pairs well with zoning. We size equipment to the actual load, not a rule of thumb, so it runs efficiently and lasts.
Permits, Title 24, and Rebates
Monte Sereno administers its building permits through the Town of Los Gatos, and every HVAC replacement has to meet California’s Title 24 energy code. We pull the permit and handle the documentation so your installation passes inspection.
Incentive programs open and close, but Silicon Valley Clean Energy currently offers heat-pump incentives for many Monte Sereno homes. If you’re upgrading from an older AC or furnace, we’ll lay out the current rebate numbers honestly and help you decide whether a heat-pump conversion makes sense for your home.
What We Do
- Cooling: AC repair and right-sized replacements.
- Heat pumps: Quiet, efficient systems that pair well with zoning.
- Heating: Furnace service and modern upgrades.
- Ductwork: Balancing for multi-level custom homes.
