HVAC, AC and Heating in Petaluma
Petaluma's warm-to-hot inland summers push afternoon highs into the upper 80s and 90s, while river-fog mornings off the Petaluma River keep things cool and damp until the marine layer burns off. That swing is hard on equipment in the historic downtown Victorians and Iron Front homes near Petaluma Boulevard as well as the newer east-side subdivisions toward Sonoma Mountain and McDowell.
Common HVAC issues in Petaluma
- Summer AC strain. Long stretches of upper-80s and 90s heat on the east side run cooling systems hard for hours, exposing low refrigerant, tired compressors and undersized units that struggle to keep up.
- Historic homes with no or old ductwork. Many downtown Victorians and Iron Front houses near Petaluma Boulevard were never built for central air, so adding ductless mini-splits is often the cleanest way to get cooling and heating without tearing into original walls.
- Big morning-to-afternoon temperature swings. Cool, foggy river mornings followed by hot afternoons mean systems cycle constantly, and poor zoning or thermostat setup leaves rooms uneven through the day.
- Ag dust and indoor air quality. Surrounding farmland, dry-season dust and pollen pull into older homes through leaky ducts, loading up filters and aggravating allergies without good filtration and sealed ductwork.
How Aaero helps in Petaluma
We handle AC repair and installation sized for Petaluma's hot inland afternoons, plus ductless mini-splits that bring efficient cooling and heating to historic downtown homes without the ductwork they never had. When an older furnace finally gives out, we repair or replace it and tune the system for those swingy fog-to-heat days.
Our Novato sheet-metal shop lets us fabricate, seal and replace duct runs on site, and we pair that with indoor air quality and filtration upgrades to fight ag dust and pollen. As a family-owned crew serving Sonoma County since 1960, we offer, when the heat or cold hits hardest.
