AfterHVAC Company in Greenwich, CT
HVAC work in Greenwich, CT is shaped by the town’s housing stock: large older colonials with steam heat, mid-century ranches with original ductwork, and shoreline properties fighting salt air, all spread across rolling terrain that makes every job a little different from the last. We’re Dalton Heating & Air, a Garrison Partners company founded in 2003, and we handle AC repair, heat pump installation, and furnace repair in Greenwich with written pricing before any work starts and a full-year written guarantee on every repair. If your system is misbehaving, call (361) 306-9515 and a live person answers, day or night.
Why Greenwich Homes Are Different
Greenwich spans from the Byram shoreline up to the backcountry north of the Merritt, and that geography splits the town into two very different HVAC realities. Homes near Cos Cob and the coastline deal with moisture and salt air that corrode condenser coils faster than inland equipment. Head north toward the four-acre zoning around Round Hill Road and Lake Avenue, and you’re looking at older estates with original steam boilers, gravity-fed ductwork, and electrical panels that were never sized for modern heat pump loads.
Housing age matters here more than in most Connecticut towns. A 1920s colonial in central Greenwich and a 1990s colonial in Riverside present completely different retrofit challenges, even when the square footage looks similar on paper. Permits are handled through the Town of Greenwich Building Division, and the town does require mechanical permits for HVAC equipment changes. HOAs in gated communities and along the shore often have their own rules about condenser placement and noise, which means the right answer on paper is sometimes not the answer the HOA will sign off on. We work through those details before we quote, not after.
Our Main Greenwich Services
Most Greenwich homeowners call us for one of three things: a system that quit in the middle of a heat wave or cold snap, a heat pump install that requires real load math, or a furnace that’s making noise it shouldn’t. Each of these has its own dedicated Greenwich page below.
AC Repair in Greenwich
Central air in Greenwich runs harder than people expect, especially in those backcountry homes where the equipment sits in full sun and the ducts run through unconditioned attics. We diagnose the common failures: failed capacitors, refrigerant leaks at the evaporator coil, contactors that pitted from salt air near the shore, and blower motors that gave out mid-July. Every repair gets a written diagnosis and a written price before we turn a wrench. If the fix doesn’t hold, we return within the one-year guarantee period at no charge. AC Repair in Greenwich covers the full breakdown, including what most repairs actually cost in town.
Heat Pump Installation in Greenwich
Heat pumps are gaining ground fast in Greenwich, especially in homes where the oil tank is coming out or where central air already exists and the homeowner wants one system that does both jobs. The catch is that Greenwich homes don’t do well with one-size-fits-all heat pump sizing. Older homes with poorly insulated walls need a proper Manual J load calculation, or the shoulder seasons will leave you uncomfortable and the electric bill will tell the story. We install systems sized to the actual envelope of the house, not the rule of thumb. Heat Pump Installation in Greenwich explains the process, the equipment options, and what a realistic install costs in town.
Furnace Repair in Greenwich
Greenwich still has thousands of homes on gas, oil, and steam heat, and when a furnace goes down in January, it’s not an inconvenience, it’s a safety issue. No-heat calls in Greenwich during a cold snap are handled as urgent, same-day priority, and our techs carry the most common parts on the truck: ignitors, flame sensors, pressure switches, gas valves, and circulator pumps for the steam and hydronic systems you still find in older sections of town. Furnace Repair in Greenwich breaks down what we check first and what the most common furnace repairs run in Greenwich.

What pushes a Greenwich job toward the higher end of those ranges is usually access: equipment in a finished attic, a furnace squeezed into a 1930s basement with a low ceiling, or a condenser pad that requires landscape work to reach. That’s exactly why we put every price in writing before any work starts. The number you approve is the number you pay, and that’s a non-negotiable part of The Garrison Standard, not a courtesy.
