AfterHVAC Company in Inverness, CA
Most Inverness homes don’t need air conditioning at all. The Point Reyes fog belt keeps summer temperatures in the low-to-mid 60s°F, so our work here centers on heating, ventilation, and moisture management in salt-laden, high-humidity conditions that corrode equipment faster than anywhere else in Marin County. Coldharbour Heating & Air dispatches technicians trained for propane systems, marine climate corrosion, and the mid-century cabins that make up much of Inverness’s housing stock. Call us at (817) 402-2972 for a free estimate.
Why Inverness Homes Are Different
Inverness sits on the Pacific Plate side of the San Andreas Fault, wrapped in Point Reyes National Seashore, where the marine layer is nearly constant and relative humidity hits near 100% many mornings. This isn’t a climate where standard HVAC equipment lasts as advertised. Salt air from Tomales Bay corrodes heat exchangers, flue fittings, and outdoor components years faster than in inland Marin towns like San Rafael or Novato.
The housing stock compounds the challenge. Most properties are mid-20th century vacation cabins and cottages, many built as summer retreats without central heating. Wood stoves and propane wall heaters were the original heat sources. A large share are now second homes or short-term rentals that sit empty for weeks, collecting moisture inside ductwork and suffering pilot or ignition failures that surface only when owners return.
There are no natural gas mains in Inverness. Every gas appliance runs on propane from on-site tanks, so our technicians size LP systems, maintain two-stage regulators, and work to the LP-specific code provisions that differ from natural gas. Propane furnaces left idle through a foggy off-season often arrive at heating season with corroded pilot assemblies, degraded flex connectors, and regulators needing rebuild before they’ll light reliably.
Our Main Inverness Services
We handle three core services for Inverness homeowners, each shaped by the local climate and propane infrastructure.
AC Repair in Inverness
True air conditioning repair is rare in Inverness, but we do service heat pumps and ductless mini-splits that provide cooling during occasional warm spells. More often, what Inverness owners call “AC trouble” is actually a ventilation or dehumidification problem, moisture trapped in a system that sat idle, or corrosion on electrical connections from salt air exposure. Our technicians diagnose whether the issue is mechanical failure or environmental damage, then quote the repair in writing before touching a tool. AC Repair in Inverness
Furnace Repair in Inverness
Furnace work dominates our Inverness calls, especially from October through April when heating demand spikes and systems that sat dormant reveal their problems. Propane furnaces here suffer from corroded burners, failed ignition modules, and regulator issues that don’t occur with natural gas systems. We carry replacement pilots, igniters, and LP-rated components for Trane, Lennox, and Rheem units, and we test the full propane delivery chain from tank to burner before declaring a repair complete.

AC Installation in Inverness
New cooling system installation in Inverness requires honest assessment of whether air conditioning is warranted at all. For homes that need it, we size heat pumps and ductless systems that handle both occasional cooling and primary heating, sized correctly for the mild climate and installed with marine-grade hardware to resist corrosion. Every installation gets a written fixed price, a scheduled install date, and full rebate and financing paperwork handled by our team. AC Installation in Inverness

What Inverness Customers Say
"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
- Celeste Ngo"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."
