HVAC and sheet metal in Larkspur since 1960
- Larkspur is a mix of historic homes along Magnolia Avenue, hillside houses up Baltimore Canyon, and newer places near the ferry. The older homes often have dated ductwork or none at all, and the canyon properties deal with shade and damp that the flats do not.

Why homeowners here call us back
In the canyon we fight the damp with right-sized heating, ductless mini-splits that bring efficient warmth and dehumidification to redwood cottages without tearing into old walls, and indoor air quality work like filtration and moisture control to keep mold and musty air in check. For downtown's vintage homes we design and fabricate proper ductwork in our own Novato sheet metal shop, and we add cooling for the bayside days when you want it.
Aaero has been the local Marin family crew since 1960, so we know how to work Larkspur's narrow lanes, tight lots and mix of historic and newer homes. We are licensed (C20 and C43), A+ rated with the BBB since 1983, and on call during business hours for emergencies across Marin.
