It is our largest service. We install Mitsubishi and Daikin cold-climate heat pumps rated to -13°F — the temperature threshold Vermont winters routinely hit. Most installations pay back within 3–6 years through reduced fuel costs. Federal IRA tax credits + Efficiency Vermont rebates can cut installation cost by $2,500–$10,500 depending on income.
Air Conditioning central AC for homes with existing ductwork and ductless mini-split AC for homes without. Many of our installs pair AC with heat pump for one system that does both heating and cooling.
It covers high-efficiency gas, oil, and propane boilers — 90%+ AFUE systems standard. We work with most Vermont fuel types and handle boiler replacement, new installations, and upgrades.
Hybrid Water Heaters cut hot-water electricity use 60–70% compared to standard electric water heaters. Federal tax credits available. Best fit: homes with basement or utility-room mechanical space and electric water heating.
Annual tune-ups, priority scheduling, warranty preservation. 150+ active Vermont households on our maintenance contracts. Mitsubishi and Daikin warranties require annual maintenance to remain valid — our maintenance plans handle the paperwork.
Vermont’s climate is brutal on HVAC equipment. -13°F nights, ice damming, freeze-thaw cycles on outdoor units, and humidity swings between summer cooling load and winter heating load — none of this forgives sloppy installation work.
Three things matter when you hire an HVAC contractor in Chittenden County:
1. Are they factory-certified on the brand they’re selling? Most contractors are not. We carry both Mitsubishi Diamond Elite and Daikin dealer certifications. Factory certification means we’ve been trained on the specific equipment, not handed a brochure.
2. Will the warranty actually be valid? Most heat pump warranties require certified installation to remain active. If your contractor isn’t certified, the manufacturer can refuse warranty claims. Our certifications keep your warranty in force.
3. Do they understand Vermont specifically? Equipment that works in Boston doesn’t always work in Burlington. The temperature differential matters. The condensate-handling matters. The clearance from snow drifts matters. We size, spec, and install for Vermont conditions.
