Do you offer emergency heating repair?

Yes, our line is answered fast, and no-heat calls across Marin and Sonoma typically see a technician within about two hours.

How much does a new furnace cost?

It depends on system type and home size, but we provide a clear, written quote up front and handle all rebate paperwork. High-efficiency upgrades often qualify for $1,000+ in rebates.

Should I switch to a heat pump?

Heat pumps heat and cool efficiently and qualify for the largest rebates. We’ll assess your home and tell you honestly whether one makes sense for you.

How often should heating be serviced?

Once a year for heating (ideally in fall), or twice a year on a maintenance plan that also covers cooling, it’s the cheapest way to avoid a no-heat emergency.

Heating in Marin County

Furnace repair, heat pump installation, and heating maintenance done right

Marin winters look mild on paper, but coastal damp, overnight inversion fog, and forty-degree mornings in the inland valleys push home heating systems hard from October through April. Aaero has serviced North Bay furnaces, boilers, and heat pumps since 1960, and we know what fails first in a Mill Valley craftsman, a San Rafael ranch, or a new Novato build. Whether you need a no-heat repair tonight or a long-term plan to electrify off natural gas, every recommendation we make is based on the system in front of us, never a one-size-fits-all upsell.

Furnace and heat pump repair on the coldest North Bay nights

A failed ignitor at ten p.m., a blower motor that won’t spin, or a heat pump stuck in defrost can turn a forty-degree Marin night miserable in a hurry. Aaero answers no-heat calls the same day across Novato, San Rafael, Mill Valley, Larkspur, Kentfield, Tiburon, and the Ross Valley, and our trucks carry the hot-surface ignitors, flame sensors, capacitors, blower modules, and reversing valves that account for the vast majority of mid-winter breakdowns. We work on Carrier, Trane, Lennox, Bryant, York, Goodman, Mitsubishi, Daikin, and older Bryant/Payne equipment, and every repair is backed by a written workmanship guarantee so you know what you paid for is what you got.

Heat pump and electrification upgrades sized for Marin homes

Marin County is one of the fastest-electrifying regions in California, and the right heat pump can heat your home, cool it in the summer, and cut combustion gas inside the house in a single move. We install variable-speed cold-climate heat pumps from Mitsubishi, Carrier, and Bosch that hold full output well below the temperatures Marin will ever see, paired with backup electric resistance or a kept-in-place dual-fuel furnace when it makes financial sense. Aaero handles the BayREN Home+, TECH Clean California, and PG&E rebate paperwork in-house, and we coordinate panel evaluations and 240V wiring with our preferred electricians so the whole project lands on one timeline.
