HVAC Company in Norwalk, CT
Dalton Heating & Air is the HVAC company Norwalk homeowners call when they want a written price before the work starts and a full-year written guarantee on every repair. Norwalk’s mix of coastal humidity, older housing stock, and neighborhoods that run from beach-level streets up into wooded hills means the heating and cooling load changes block by block. If your AC or furnace is acting up, call us at (361) 306-9515 and a real person answers, 24 hours a day.
Why Norwalk Homes Are Different
Norwalk sits right on Long Island Sound, and that changes the work. Salt air moves through outdoor condenser coils faster than it does ten miles inland, which means corrosion is a regular culprit on AC calls in Rowayton, East Norwalk, and anywhere within a mile or two of the water. At the same time, Norwalk’s inland neighborhoods – Cranbury, Silvermine, West Norwalk – deal with a different set of conditions: older colonials and capes with tighter mechanical closets, and plenty of homes built before central air was standard. A lot of Norwalk’s housing stock dates from the 1950s through the 1980s, so we routinely work on systems that were retrofitted into existing ductwork, not sized for the house from day one. That matters because a retrofit system that was never properly load-calculated will run short on the hottest July days. Norwalk also has elevation changes that affect how we approach a job – a condenser swap on a flat lot near Norwalk Harbor is a different day than one on a sloped yard off New Canaan Avenue where we need to level a pad and run a longer lineset. The permit office requires mechanical permits for most equipment replacements, and we handle that paperwork as part of the job.
Our Main Norwalk Services
The two calls we get most from Norwalk homeowners are air conditioning failures in summer and furnace problems in winter, with heat pump installations growing as more homes move away from oil. Here’s how each one works in Norwalk.
AC Repair in Norwalk
Most AC repair calls in Norwalk fall into a few familiar patterns: a condenser coil corroded by salt air near the Sound, a capacitor that gave out on a 90-degree day, or a system low on refrigerant. We diagnose the exact fault, put the repair price in writing before any work begins, and then do the job. If the repair fails within a full year, we come back at no charge – that’s the 365-Day Done Right Promise, and it’s included on every call. We service AC Repair in Norwalk for all major brands and stock common parts on our trucks so most repairs are done in one visit.

Heat Pump Installation in Norwalk
A heat pump handles both heating and cooling, and for many Norwalk homes it’s the right long-term move off oil or propane. The installation involves a load calculation, a written fixed price, and a set install date – this is not same-day work, and if anyone promises you a same-day heat pump install, walk away. Norwalk’s older homes often need an electrical panel check before we pull a permit, since a heat pump adds a 240-volt circuit. We’ll confirm what’s needed, order the equipment, and give you a written price before any work starts. Crews serving Heat Pump Installation in Norwalk are factory-trained on Rheem, York, Daikin, and Bryant, among others.

Furnace Repair in Norwalk
Norwalk winters are cold enough that a furnace failure on a January night is a real problem, not an inconvenience. Common failures we see in Norwalk homes include igniters on gas furnaces, limit switches, and blower motors that have run for 15 years without service. Every furnace repair comes with a written price up front and a written guarantee for a full year. If the repair fails in that window, we return free of charge. We stock parts for most major furnaces on our trucks, so Furnace Repair in Norwalk is usually completed in a single visit.
