AfterHVAC Company in Sleepy Hollow, CA
Most Sleepy Hollow homes have never had central air conditioning, and they probably never will. The shaded, tree-canopied canyon sits in a pocket of Marin County where summer temperatures rarely climb out of the 70s, so our work here is almost entirely heating-focused: replacing aging floor furnaces and wall heaters from the 1950s through 1970s, and installing heat pumps for homeowners discovering them for the first time. Coldharbour Heating & Air handles AC repair, furnace repair, and AC installation in Sleepy Hollow with technicians trained on Goodman, Rheem, York, and Daikin systems. Call (817) 402-2972 for a free estimate.
Why Sleepy Hollow Homes Are Different
Sleepy Hollow’s literal bowl-and-canopy geography creates a microclimate that neighboring San Anselmo and Ross simply don’t share. The dense coast live oak and California bay laurel canopy keeps the canyon persistently cooler and more humid, which means two things for HVAC work: no cooling demand to speak of, and accelerated corrosion on whatever heating equipment does sit outside or in crawl spaces.
The housing stock reinforces this heating-only reality. Most homes are custom and semi-custom mid-century builds on wooded hillside lots with raised foundations or tight crawl spaces. Original gravity-fed floor furnaces and single-wall gas heaters remain common, and retrofitting modern equipment into these floor plans presents code-compliance and ductwork challenges that flat-suburb technicians rarely encounter. The heavy organic debris dropped year-round by that same tree canopy packs outdoor mini-split heads and ground-level equipment with decomposed leaf matter, a maintenance failure mode we see consistently here and almost nowhere else in Marin.
Our Main Sleepy Hollow Services
Sleepy Hollow homeowners call us for two primary needs: keeping legacy heating systems running through the marine-layer season, and upgrading to modern heat pumps that handle both heating and occasional cooling. Here’s what each job looks like in this canyon.
AC Repair in Sleepy Hollow
True AC repair calls in Sleepy Hollow are rare, but they do happen, usually for ductless mini-split systems or the occasional heat pump cooling cycle. When we get them, the problem is often debris-related: that dense oak and bay laurel canopy clogs outdoor condenser coils faster than in any neighboring town. Our technicians clean the coils, check refrigerant levels (the cooling fluid your system needs to run), and verify that the defrost cycle works properly in Sleepy Hollow’s humid shade.

Furnace Repair in Sleepy Hollow
This is the bulk of our Sleepy Hollow work. We repair gravity-fed floor furnaces, wall-mounted gas heaters, and early forced-air systems that have kept these canyon homes warm since the Eisenhower administration. Common failures include cracked heat exchangers (the metal chamber that separates combustion gases from your breathable air), failed thermocouples (the safety sensor that confirms the pilot flame is lit), and corroded gas valves from decades of marine-layer moisture. Every repair comes with our written 365-Day Done Right Promise. Furnace Repair in Sleepy Hollow
AC Installation in Sleepy Hollow
When Sleepy Hollow homeowners install “AC,” what they usually mean is a heat pump: a single system that heats efficiently and cools on the handful of warm afternoons the canyon sees each year. These installs require careful load calculation for homes that never had ductwork, often using ductless mini-splits or high-velocity small-duct systems that fit into tight hillside floor plans. We handle the sizing, permitting, and rebate paperwork, and we schedule a firm install date once equipment is ordered. AC Installation in Sleepy Hollow

Yes, Marin County requires permits for furnace replacements, and hillside homes may need additional structural or environmental review. We pull the permit as part of every installation and schedule inspections around your availability.
Modern cold-climate heat pumps operate efficiently well below 40 degrees, which covers every night Sleepy Hollow experiences. The bigger question is whether your home’s electrical panel can handle the load, which we assess during your free estimate.

What Sleepy Hollow 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."
