Upstairs hot, downstairs freezing?

Stop fighting over the thermostat. Zoning lets you heat and cool different areas of your Marin home independently, more comfort, less wasted energy, and lower bills.

If the upstairs bedrooms run hot at night while the kitchen stays cold all afternoon, Aaero installs whole-house zoning systems across Marin County that fix the imbalance without forcing you to oversize the entire HVAC system. We design two-, three-, and four-zone setups with motorized dampers, variable-speed air handlers, and ecobee or Honeywell smart thermostats, calibrated against a Manual J load and Manual D duct analysis so each zone gets the airflow it actually needs. The result is even room-to-room temperatures, lower PG&E bills, longer equipment life, and quiet operation because the system finally runs at part-load most of the day.
End the upstairs-downstairs war.
A zoned system splits your home into independently controlled areas, motorized dampers in the ductwork plus a thermostat for each zone, so the upstairs bedrooms and the downstairs living areas hold their own temperatures at once. We map the zones to how your Marin home is actually lived in and lay out the design before any work starts.

More ways to even out your home
Zoning pairs well with the rest of our work, from a right-sized system to a ductless mini-split for that one room the ducts never reach. Voted Marin County's Best HVAC Company by the Marin Independent Journal. Family-owned by David Milano Jr. and Cindy Milano. CA License #278370, C20 & C43.
AC Repair
Won’t turn on. Blowing warm. Tripping the breaker. We diagnose what’s actually wrong, quote upfront pricing, and have most homes cooling again the same day.
Installation & Replacement
When repair stops making sense, we sit down with you on a new system, sized correctly for your square footage, ductwork, and energy goals. No oversold equipment. Real rebate help.
Maintenance Plans
Spring and fall tune-ups catch problems before they break the system. Members get priority scheduling, discounted repairs, and a written record that keeps manufacturer warranties valid.
Mini-Split Installation
Converted garage that’s always 10° off? Addition with no ducts? Mini-splits heat and cool one space at a time, quiet, efficient, and a fraction of the cost of central system retrofits.
