The Crew Behind Green Mountain Heating & Cooling in Vermont
Last Updated: 10/20/2026
Built for Vermont Winters, One Home at a Time
Green Mountain Heating & Cooling started with a simple observation: older Vermont homes punish HVAC shortcuts. We have spent 11+ years working across the state, from Chittenden County basements to hilltown farmhouses, and we learned early that a furnace sized off a square-foot chart alone will short-cycle by January. Load calculations that account for insulation, window age, and wind exposure are what keep a system honest through a cold snap.
We are an insured contractor with EPA Section 608 refrigerant handling certification and NATE-certified HVAC technicians on every job. Homeowners hire us for furnace repairs, AC installations, and straight answers about whether a repair is worth the money. Clear estimates come before work, job sites get protected, and you hear from us at every step from the first call to the finished system.
Who Runs the Trucks and Answers the Phone
Daniel Mercer founded Green Mountain Heating & Cooling after growing up near Burlington and learning the trade in older homes where cold winters tested every heating system. He started the company to give Vermont homeowners clear advice on furnace repairs and AC installations, with work planned around each house instead of a one-size script.
The team schedules service across Vermont by grouping calls by region and budgeting for the extra travel statewide coverage requires. That means a Rutland County call gets a realistic arrival window, not a guess.
Technicians explain repair options in plain terms, coordinate installation details before equipment shows up, and account for local permit requirements ahead of the work. When a customer asks why we recommend a repair over a replacement, the answer comes with numbers, not pressure.
Reliable heating and cooling across Vermont starts with people who know which towns lose power first and which basements flood in mud season.
What We Hear When Homeowners Call
Most calls start with a symptom that has been building for weeks. Here are the situations we see most often around Vermont, including homes near the Church Street Marketplace area in Burlington:
- AC runs but blows warm air: Usually a refrigerant or capacitor issue running it this way strains the compressor.
- Furnace starts then shuts off: A flame sensor or limit switch problem that will not fix itself.
- Uneven heat between upstairs rooms: Often duct balance or insulation, not a failing furnace.
- Furnace makes loud banging noises: Delayed ignition or duct expansion worth checking before it worsens.
- AC outdoor unit will not start: Could be a tripped breaker, contactor, or thermostat wiring.
- Burning smell from furnace vents: Dust burn-off is normal once; a persistent smell is not.
- Thermostat setting differs from room temperature: Placement, calibration, or a failing sensor.
If any of these sound familiar, it is worth a diagnosis before the next cold front arrives.
How We Work, Step by Step
Every job starts with an estimate you can read, then a plan that matches the house. Refrigerant work follows our EPA Section 608 certification and the Clean Air Act recovery requirements we recover refrigerant before any equipment gets scrapped, never vent it. Covered projects meet Vermont Residential Building Energy Standards, and installations comply with the Vermont Fire and Building Safety Code.
Permits are handled before tools come out. Burlington mechanical permits go through the City of Burlington Department of Permits and Inspections, and we verify scope with the city rather than assume.
Regulated wiring falls under Vermont electrical licensing, and refrigerant disposal follows Vermont Department of Environmental Conservation rules. One detail out-of-town crews miss: mud season access.
A driveway that held a delivery truck in February can swallow one in April, so we plan equipment staging around thaw conditions. Our technicians hold NATE certification, and we keep the Vermont Department of Public Service efficiency guidance in mind when sizing replacements.
Talk It Through Before You Commit
If your furnace is limping through its third Vermont winter or an AC quote does not add up, call (555) 010-0000 and describe what you are seeing. We will tell you what it likely means and what a visit would involve no obligation, no pressure. Prefer to plan ahead? A fall furnace check before heating season is the easiest money you will spend all year.
