Why Coldharbour Heating & Air Is Corte Madera’s Preferred AC Installation Company
We’re independently owned and operated as part of the Kingswell network, which means we follow The Kingswell Way: say the price before the work starts, show up in the window promised, leave the place cleaner than we found it, put every guarantee in writing, and come back if it fails. Corte Madera homeowners have told us that last part matters most after dealing with companies that vanished when a repair didn’t hold.
Our technicians are background-checked, uniformed, and trained on nine major residential HVAC brands including Trane, Lennox, Goodman, and Rheem. When you call (817) 402-2972, a live person answers, 24 hours a day, every day of the year. No voicemail trees, no callbacks tomorrow morning.
We know Corte Madera’s housing stock because we’ve worked in it. The post-war tract homes in the flatlands, the mid-century ranches near Tamalpais Drive, the hillside builds with their own challenges near Ring Mountain. That local familiarity means we spot problems before they become change orders: damp crawl spaces, undersized electrical panels, ductwork that looks fine from the vent but is disintegrating underneath.
HVAC Installation in Corte Madera
HVAC Installation in Corte Madera is almost always a heating-and-cooling replacement project rather than a cooling-only addition, because this town’s marine climate keeps summer highs in the low-to-mid 60s°F while winter mornings sit in the mid-50s even in July. Most homeowners we meet aren’t looking for central air conditioning for comfort in August; they’re replacing an aging furnace with a heat pump system that handles both heating and dehumidification, or they’re adding capacity because the original 1950s-70s equipment simply can’t keep up anymore. A full system replacement in Corte Madera runs $3,500-$7,500 depending on equipment size, ductwork condition, and whether electrical upgrades are needed.
When Replacement Makes Sense
If your current system is past 15 years, needs refrigerant recharge every season, or leaves some rooms 10 degrees colder than others, replacement usually costs less over five years than repeated repairs on failing equipment. We run a Manual J load calculation to size the new system correctly, not just read the old nameplate.
The Electrical Reality
Many Corte Madera flatland homes still have 100-amp panels or ungrounded circuits. A modern heat pump and air handler can draw more than those systems were built for. We scope the electrical upgrade during the estimate, not on install day when everyone’s waiting.
Heat Pump Installation in Corte Madera
Heat Pump Installation in Corte Madera has become our most common replacement project because heat pumps handle this climate efficiently: they extract warmth from outdoor air down to surprisingly low temperatures, which covers Corte Madera’s mild winters, and they provide cooling for the few genuinely warm days each year. A properly sized heat pump also dehumidifies better than the old gas furnaces many homes still run, which matters in crawl spaces where moisture already lingers. Expect $3,500-$7,500 for a complete heat pump installation with matched indoor coil and air handler.
Ductwork Before Equipment
We won’t set a new heat pump on top of failing ductwork. In the flatlands near Corte Madera Creek, we’ve found 20-year-old flex duct performing like 35-year-old material because of ground moisture wicking into crawl spaces. We test static pressure and seal or replace runs as needed so the new equipment can actually reach its rated capacity.
Rebates and Efficiency Ratings
Heat pumps qualify for federal tax credits and often local utility rebates. We handle the paperwork during installation so you don’t chase it down afterward. The efficiency rating (SEER2 for cooling, HSPF2 for heating) affects both your rebate amount and long-term operating cost.
Trusted Brands We Service in Corte Madera
Our technicians carry training certifications on Trane, Lennox, Goodman, and Rheem, and we stock common parts for these brands at our Bay Area warehouse so Corte Madera customers aren’t waiting a week for a coil or control board. We also work with Carrier, Daikin, Bryant, York, and American Standard when your existing system or preferred equipment calls for it. Every installation uses a matched indoor coil and air handler sized to the outdoor unit, not a mix-and-match approach that voids warranties and cuts efficiency. If you’re replacing an older system, we’ll show you the efficiency difference between your current setup and what a modern 16+ SEER2 unit delivers in actual dollars on your utility bill.
Common AC Installation Problems We See in Corte Madera Homes
- Leaky original ductwork hidden in damp crawl spaces. Homes built on former tidal marsh along Corte Madera Creek hold ground moisture that degrades flex duct insulation and corrodes fittings. A new condenser fighting 30% duct leakage never reaches rated capacity, and the homeowner blames the equipment.
- Electrical panels that can’t carry modern loads. Many flatland ranches still have 100-amp service or ungrounded branch circuits. A heat pump and air handler combination can pull 60 amps alone, so the panel upgrade has to be in the original scope, not a surprise add-on.
- Single-zone systems struggling with unbalanced floor plans. The 1950s-70s tract layouts in Corte Madera often have additions, converted garages, or upstairs bedrooms that the original single-thermostat system was never designed to serve evenly.
- Like-for-like tonnage swaps that ignore actual load. Sizing off the old nameplate assumes the original builder got it right and that nothing has changed. In reality, added insulation, new windows, or enclosed patios change the load, and degraded ductwork means the old “3-ton” label was already underperforming.

FAQs About AC Installation in Corte Madera
The original ductwork is almost certainly leaking or undersized for the floor plan. In flatland Corte Madera homes, we’ve measured 30% or more air loss through degraded flex duct in damp crawl spaces before the conditioned air ever reaches the vent. A new condenser can’t fix that. We test static pressure and seal or replace failing runs so the new equipment can actually deliver where it’s supposed to. Call (817) 402-2972 and we’ll check it during your free estimate.
Yes, because heating demand here runs nearly year-round. Corte Madera’s marine climate means July and August mornings regularly sit in the mid-50s, and winter lows dip into the 40s. A heat pump handles both efficiently, replacing a separate furnace and eliminating the need for a cooling-only system you’ll barely use. Most Corte Madera homeowners we install for use their heat pump’s heating mode 10 months of the year.
Three things: ductwork condition in the crawl space, electrical panel capacity, and actual load calculation. The flatland homes near Corte Madera Creek have chronically damp crawl spaces that degrade ductwork and corrode fittings faster than age alone would predict. Many also have 100-amp panels that can’t support a modern heat pump. We scope all three during our free estimate so there are no surprises on install day.
Ground moisture wicks into low-clearance crawl spaces in Corte Madera’s bay-side flatlands, degrading flex duct insulation and corroding metal fittings. We’ve found 20-year-old systems performing like 35-year-old equipment because of this. If we install new equipment on top of failing ductwork, the new system inherits the same leaks and never reaches rated efficiency. We test, seal, or replace ductwork as part of the installation scope when needed.
Yes. Mini split systems use small refrigerant lines run through walls, with individual wall or ceiling cassettes in each zone. They’re ideal for Corte Madera homes with no existing ductwork, converted garages, or additions that the central system never served well. We size each indoor unit to its zone and handle the electrical run from the outdoor compressor. Call (817) 402-2972 for a free estimate on mini split installation.
