HVAC Company in Corte Madera, CA
Most HVAC work in Corte Madera is heating repair and indoor air quality, not cooling. The town’s marine climate keeps summer highs in the low-to-mid 60s°F, so central AC rarely runs, while heating demand stretches nearly year-round with July mornings still in the mid-50s. Coldharbour Heating & Air dispatches technicians from our San Francisco Bay Area office to serve Corte Madera homes directly. Call us at (817) 402-2972 when you need a live person, any hour.
Why Corte Madera Homes Are Different
Corte Madera’s flatlands were built out heavily in the 1950s through the 1970s on reclaimed Bay fill and former tidal marsh along Corte Madera Creek. That history matters for every service call we make. Crawl spaces under those mid-century homes stay chronically damp, degrading flex duct joints and corroding HVAC fittings far faster than age alone would predict. A 20-year-old system here often looks and performs like a 35-year-old system from drier inland towns.
The persistent marine air funneling between San Francisco Bay and the Marin hills compounds the problem. Salt-laden bay air attacks metal components, while the moisture wicking up from former-marsh soil saturates insulation and rusts out gas furnace heat exchangers we rarely see fail so early elsewhere. Hillside pockets near Ring Mountain carry a different profile, some with pre-war construction and minimal original ductwork, but the majority of our calls come from those flatland neighborhoods where the ground itself works against the equipment.
What this means practically: Corte Madera furnace repairs often involve replacing components that failed prematurely from corrosion, not simple wear. Duct inspections here are non-negotiable, because the crawl space environment hides damage that would be obvious in a drier climate. We factor this into every estimate and every recommendation.

AC Repair in Corte Madera
AC repair in Corte Madera is usually a specific fix, not seasonal maintenance. Most systems run only a handful of days each year, so when a homeowner calls, it’s typically because a heat pump or cooling unit has stopped working entirely during a rare warm spell, or because a ductless mini-split serving a single room has thrown an error code. We check refrigerant levels (the cooling fluid your system needs), test capacitors (the electrical components that start the compressor), and inspect condensate drains that can clog with the area’s airborne salt and moisture. Our technicians carry parts for Trane, Lennox, Goodman, and Rheem systems on their trucks, so most Corte Madera AC repairs finish in one visit. AC Repair in Corte Madera

Furnace Repair in Corte Madera
Furnace repair is the bulk of our Corte Madera workload. Gas furnaces in this town run hard from October through May and often cycle on even in summer mornings. The damp crawl spaces corrode igniters, flame sensors, and heat exchangers at accelerated rates. We regularly find Goodman and Rheem furnaces in the flatland neighborhoods with rusted burner assemblies that would last years longer in drier Larkspur or Mill Valley conditions. Every furnace repair we complete comes with our written 365-Day Done Right Promise, and we hand you the price before touching a tool. Furnace Repair in Corte Madera

AC Installation in Corte Madera
AC installation in Corte Madera requires honest load calculation, not guesswork. Because cooling degree-days are minimal here, oversized systems short-cycle and dehumidify poorly, while undersized units strain on the few hot afternoons. We size every installation to the actual heat gain of the home, accounting for Marin County’s specific insulation values and the cooling effect of prevailing bay breezes. Most Corte Madera AC installations are heat pumps or ductless mini-splits that handle both heating and cooling, given the year-round heating demand. We provide a written fixed price, schedule a firm install date, and handle all rebate and financing paperwork. AC Installation in Corte Madera

FAQs About HVAC Company in Corte Madera
We dispatch from our San Francisco Bay Area office and typically schedule same-day or next-day arrival for heating repairs, depending on call volume. A live person answers the phone 24 hours a day to set your appointment and give you a firm window. Call (817) 402-2972 to check today’s availability.
Most furnace replacements and new AC installations require a Marin County permit; simple repairs and tune-ups generally do not. We handle permit applications as part of any installation job and schedule inspections so you don’t have to coordinate with the county yourself.
Replace when repair costs exceed roughly 40% of a new system’s price, when the heat exchanger is cracked (a safety issue), or when corrosion from damp crawl spaces has damaged multiple components. We’ll show you both options with exact numbers so you can decide. Call (817) 402-2972 for a free estimate.

What Corte Madera Customers Say
"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
