AfterHVAC Company in West Haven, CT
Most West Haven homeowners spend between $150 and $700 on HVAC repairs and $3,500 to $7,500 for a full AC installation, with same-day repair availability when you call (817) 402-2972. We’re Coldharbour Heating & Air, and we handle the specific challenges that come with coastal Connecticut HVAC work: salt-air corrosion on Long Island Sound, pre-1960s housing stock with aging oil boilers, and the flood-elevation code requirements that inland contractors rarely encounter. Our technicians are dispatched from our Hartford office and serve West Haven homes directly.
Why West Haven Homes Are Different
West Haven’s location on Long Island Sound creates a double burden for heating and cooling equipment. The salt-laden coastal air corrodes condenser coils, refrigerant fittings, and cabinet metal far faster than in inland cities like Ansonia or Derby. Summer dew points routinely sit in the 65-70°F range, so air conditioners work harder here to pull moisture from the air, not just drop the temperature.
The housing stock tells its own story. Pre-1960 two- and three-family homes and post-WWII Cape Cods built for New Haven’s factory workforce still dominate many blocks. Most were designed around oil-fired boilers and gravity hot-water baseboards, with ductwork added later or never installed at all. In Savin Rock, we’re seeing steady conversion of beach cottages from summer-only use to year-round living, which means sizing and placing equipment in structures never engineered for winter heating.
After Hurricane Sandy flooded shoreline areas in 2012, FEMA remapping placed many coastal parcels in Special Flood Hazard Areas. That means furnaces, air handlers, and heat pumps must sit above Base Flood Elevation, a code reality our West Haven crews handle routinely but inland contractors often miss entirely.
Our Main West Haven Services
These are the three services West Haven homeowners call us about most often.
AC Repair in West Haven
When an air conditioner fails during a humid July stretch, the problem is often salt corrosion on the outdoor condenser or a refrigerant leak at a fitting eaten away by coastal air. We carry common capacitors, contactors, and refrigerant so most AC Repair in West Haven jobs finish in a single visit. Every repair comes with our written 365-Day Done Right Promise.
Furnace Repair in West Haven
Many West Haven homes still heat with original oil-fired equipment, and when a burner motor fails or a heat exchanger cracks, you need a technician who understands both legacy systems and modern retrofits. Our Furnace Repair in West Haven covers everything from igniter replacements on 30-year-old boilers to control-board failures on newer gas furnaces.
AC Installation in West Haven
New system installs in West Haven often involve more than swapping boxes. Homes without existing ductwork need mini-splits or high-velocity systems, and coastal flood zones require elevated equipment placement. We size every AC Installation in West Haven to the home’s actual heat load, not the old unit’s label.

What West Haven Customers Say
"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
- Marcus Reilly"Furnace wouldn't light the first cold morning. The guy walked me through what he was checking so I actually understood it. Replaced the igniter, wrote up the warranty, and it's been warm since."
- Alicia Romero"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."
