AfterHVAC Company in Stamford, CT
Dalton Heating & Air is the HVAC company Stamford homeowners call when a system fails and they want a straight answer, a written price, and a technician who shows up inside the stated window. Stamford’s housing stock runs the full range: pre-war colonials near Glenbrook, 1960s ranches in Springdale, new construction down by Harbor Point. That mix means we see boiler-to-ductwork conversions, aging condensers, and oversized heat pumps installed by previous contractors who never ran a load calculation. We service all nine major residential brands, so whatever equipment is already in your Stamford home, we can work on it. Call (361) 306-9515 and a real person answers, 24/7.
Why Stamford Homes Are Different
Stamford sits on Long Island Sound, and that coastal position shapes HVAC work in ways homeowners don’t always anticipate. Air carries salt and moisture. Condenser coils and outdoor electrical connections corrode faster here than they do ten miles inland in Danbury or Ridgefield. We regularly open outdoor units on Shippan Point and find coil fins that look five years older than the unit actually is. If your AC has been losing capacity slowly, salt air is a likely contributor. Homes along the water also run humidifiers and dehumidifiers harder, which puts more load on ductwork and filtration than a typical inland system sees.
The housing stock itself creates a second variable. Stamford has thousands of homes built between 1920 and 1970, many with original ductwork sized for oil-fired furnaces rather than modern heat pumps. Converting one of those systems requires an honest measurement of static pressure and airflow, not a simple equipment swap. In neighborhoods like Westover and Turn of River, we also see a lot of split-level and raised-ranch layouts where duct runs are long and poorly insulated. That changes how a heat pump performs and what size makes sense. Add in city permit requirements for mechanical work, and Stamford jobs demand a crew that does it by the book the first time. The Garrison Code we operate under: arrive inside the stated window, price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year.
Our Main Stamford Services
Most calls we take in Stamford fall into three buckets: a cooling system that stopped cooling, a furnace that won’t fire, or a homeowner planning to replace aging equipment with a heat pump. Each of those has its own page below, with the pricing detail and the full scope of work.
AC Repair in Stamford
When a central air system fails in a Stamford summer, the humidity makes the house uncomfortable within hours. The most common failures we see here are refrigerant leaks on older R-22 systems, failed capacitors, and condenser coils choked with salt-air corrosion. On every call we diagnose the fault, put the repair price in writing, and then do the work. The repair is guaranteed in writing for a full year. If it fails in that time, we return at no charge. Details on cost ranges and what we fix are on our AC Repair in Stamford page.
Heat Pump Installation in Stamford
Stamford homeowners are replacing oil furnaces and older central AC with heat pumps in growing numbers, and for good reason: a properly sized heat pump handles both heating and cooling from one unit. The catch is that proper sizing matters more here than in mild climates. Coastal humidity in July and single-digit nights in January demand a unit matched to the home’s actual load, not a guess. We run the load calculation, address ductwork shortfalls, and give a written fixed price before any equipment is ordered. See the full scope and pricing on our Heat Pump Installation in Stamford page.
Furnace Repair in Stamford
Most furnace failures in Stamford happen in the first cold snap of the season, when a system that idled for months gets asked to run flat-out. We see failed igniters, dirty flame sensors, and cracked heat exchangers on older units throughout the city, south of the Merritt and north of it. No heat is a health risk in a Fairfield County January, so we treat furnace calls as emergencies and get a technician to you the same day in nearly every case. Full pricing detail is on our Furnace Repair in Stamford page.

Pricing for HVAC Company in Stamford, CT
These are the real dollar ranges we quote in Stamford. The price you get is in writing before any work starts, and it does not change once the job is underway.
| Service | Typical Range in Stamford |
|---|---|
| AC Repair | $150 – $650 |
| Furnace Repair | $150 – $700 |
| AC Installation | $3,500 – $7,500 |
| Tune-Up | $80 – $200 |
What pushes a Stamford job toward the top of those ranges is usually access: attics in older colonials, crawlspaces in ranch homes, or outdoor units boxed in by decks and fencing. Coastal corrosion also means more parts replacement than a tune-up-only inland job. Whatever the number, it is in writing before we begin, and there is no overtime charge for emergency calls.
