A properly sized central air system is the difference between a home that's comfortable all summer and one that runs constantly and still can't cool down. We install central AC systems that are sized right, installed clean, and built to last.
Boilers, furnaces, heat pumps, and emergency heating repair across Fairfield County CT & Westchester County NY
GET A FREE HEATING ESTIMATEHeating isn't optional in Connecticut and Westchester County. Between October and April, your heating system runs for hundreds of hours — and when it fails, you need a contractor who answers the phone at 2 AM, shows up the same day, and fixes it right the first time.
Airmax installs and services every type of heating system used in the Northeast: boilers (gas, oil, and propane), furnaces, heat pumps (air-source and dual-fuel), ductless mini-splits, and radiant floor heating. We're licensed in both Connecticut (HTG.0414617-D1) and New York, and we've been keeping homes warm across Fairfield and Westchester Counties for years.
Whether you're replacing a 30-year-old oil boiler, converting from oil to gas, adding a heat pump for efficiency, or just need your furnace serviced before winter — we handle it all.
Boilers are the most common heating system in older Connecticut and Westchester homes. They heat water (or generate steam) and distribute warmth through radiators, baseboard convectors, or radiant floor tubing. When properly installed, a modern high-efficiency boiler can last 20–30 years and cut your fuel bills by 20–35% compared to an older unit.
We install and service boilers from Weil-McLain, Navien, Burnham, and Buderus. We handle gas, oil, and propane systems — and we're one of the few contractors in the area with deep experience in oil-to-gas conversions.
Installed cost: $5,500–$15,000+ depending on system size, fuel type, and whether you're converting from oil to gas. Get your specific estimate →
Furnaces heat air and blow it through your ductwork. They're the standard heating system in homes built with central HVAC in mind. Modern high-efficiency furnaces achieve 96–98% AFUE, meaning almost every dollar you spend on fuel goes to heating your home.
We install furnaces from Carrier, Lennox, and Trane. Whether you need a straightforward replacement or a completely new duct system, we handle the full job — including permits, load calculations, and inspections.
If your home already has ductwork, a furnace is usually the more cost-effective choice. If you have radiators or baseboard heat, a boiler replacement makes more sense. If you're building new or doing a major renovation, we'll run the numbers on both options. Read our full comparison guide →
Installed cost: $3,500–$10,000+ depending on size, efficiency rating, and ductwork requirements.
Heat pumps are the fastest-growing heating technology in the Northeast. They work by moving heat rather than generating it, making them 2–3x more efficient than traditional systems. Modern cold-climate heat pumps perform well down to -15°F — more than adequate for Fairfield and Westchester County winters.
We install air-source heat pumps from Carrier, Mitsubishi, and Trane. For homes that want heat pump efficiency with a gas furnace backup, we build dual-fuel systems that automatically switch based on outdoor temperature — giving you the best of both worlds.
Connecticut offers significant incentives for heat pump installations through the Energize CT program. Depending on your utility and the system type, rebates can reach $1,500–$3,000+ per system. We handle the rebate paperwork for you. Check our 2026 CT rebate guide for current incentive amounts.
Installed cost: $4,500–$12,000+ before rebates. Actual out-of-pocket is often significantly less.
