Best Hvac Companies in Vermont 2026
HVAC is not a luxury category in Vermont — it is a survival category. With winters that routinely drop below zero, heating systems that fail on a January night can mean frozen pipes, water damage, and emergency hotel stays within hours. Vermont’s HVAC market has also changed dramatically in the past five years as cold-climate heat pumps have moved from niche technology to mainstream adoption, driven by Efficiency Vermont rebates of up to $4,000 and federal tax credits of up to $2,000. The best HVAC companies in Vermont now need expertise in both traditional oil and gas systems and modern heat pump technology — a combination that not every shop has developed. If you own a home or are buying a home in Vermont, choosing the right HVAC company affects your comfort, your energy bills, and your home’s resale value. This ranking evaluates the top HVAC firms in Vermont for 2026 based on licensing, client reviews, service range, pricing, and their ability to handle the state’s specific heating challenges.
Vermont requires HVAC technicians to hold a Journeyman or Master Plumber/Heating license issued by the Office of Professional Regulation for work involving gas piping, boilers, and hydronic systems. Refrigerant handling (heat pumps and air conditioning) requires EPA Section 608 certification. Always verify these credentials before hiring — unlicensed work can void equipment warranties and create safety hazards.

1. Vermont Energy Systems — South Burlington
Vermont Energy Systems (VES) is the most complete HVAC operation in the state, covering oil boilers, gas furnaces, cold-climate heat pumps, air conditioning, ductwork, and water heaters from their South Burlington base. With 28 technicians and 14 service trucks, they have the capacity to handle both scheduled installations and emergency calls across Chittenden, Lamoille, and Washington counties. VES performs roughly 1,200 service calls and 300 installations per year, making them the highest-volume HVAC firm in Vermont.
Their heat pump division has grown rapidly — VES is a Mitsubishi Diamond Contractor and a Fujitsu Elite dealer, meaning their technicians receive manufacturer-specific training and can offer extended warranties. They also maintain a strong oil and gas service department, which matters in Vermont because most heat pump installations supplement rather than replace existing heating systems. Clients report that VES pricing is competitive but not the cheapest; their value is in reliability, technical competence, and same-day emergency response during heating season.

2. Champlain Valley Heating & Cooling — Williston
Champlain Valley Heating (CVH) has been serving the greater Burlington area for 30 years, with a workforce of 18 technicians. They have the longest track record of any HVAC firm on this list and a loyal client base built on consistent service quality. CVH’s strength is oil and gas systems — they service approximately 4,000 oil heating accounts across Chittenden County and have deep expertise in maintaining, repairing, and replacing the aging oil boilers that heat the majority of Burlington-area homes.
Their heat pump program is newer but growing. CVH added a dedicated heat pump installation team in 2021 and now handles about 150 heat pump installations per year. They are a Daikin authorized dealer and can install Mitsubishi, Fujitsu, and LG systems as well. Where CVH excels is in hybrid system design — integrating heat pumps with existing oil or gas systems so that the heat pump handles the majority of the heating load while the fossil fuel system provides backup during the coldest stretches. This approach maximizes efficiency while ensuring you never lose heat, even at -20°F.
- Service area: Chittenden County, southern Franklin County, northern Addison County
- Certifications: VT Master Plumber/Heating, EPA 608, NATE, Daikin authorized
- Services: Oil boilers, gas furnaces, heat pumps, hybrid systems, oil delivery
- Emergency response: 24/7, average response 2-6 hours
- Average client rating: 4.7/5 (112 reviews)
- Maintenance plans: $179–$299/year (oil tune-up + 24/7 emergency priority)
3. Central Vermont Mechanical — Barre
Central Vermont Mechanical (CVM) is the go-to HVAC firm for Washington County, Orange County, and the Upper Valley. Based in Barre with a team of 12 technicians, they cover the geographic middle of the state that Burlington-based companies often do not reach. CVM handles oil, propane, and heat pump systems, with a particular focus on the affordable end of the market — their client base includes many homeowners on tight budgets who need reliable heating at reasonable prices.
CVM has become the primary installer of cold-climate heat pumps in the Montpelier-Barre area, handling approximately 120 installations per year. They are experienced with the Efficiency Vermont rebate process and help clients navigate the paperwork, which can recoup $1,500–$4,000 of the installation cost. Their oil service department maintains about 2,500 accounts. Post-2023 flood, CVM replaced or repaired heating systems in dozens of Montpelier homes and has specific experience with the damage patterns that flood water causes to boilers, furnaces, and ductwork.
- Service area: Washington, Orange, Lamoille counties, Upper Valley
- Certifications: VT Master Plumber/Heating, EPA 608, Fujitsu authorized
- Services: Oil boilers, propane furnaces, heat pumps, water heaters, ductwork
- Emergency response: 24/7, average response 3-6 hours
- Average client rating: 4.8/5 (87 reviews)
- Maintenance plans: $159–$269/year
4. Southern Vermont Heating — Brattleboro
Southern Vermont Heating covers Windham and Bennington counties from their Brattleboro base, serving an area that would otherwise require calling contractors from Burlington (2.5 hours away) or crossing state lines. The team of 8 technicians handles oil, propane, and heat pump systems for roughly 1,800 service accounts. Owner Tim Harwood is a Master Plumber/Heating licensee with 20 years of experience, and the firm has been a fixture in the Brattleboro community for 16 years.
Southern Vermont Heating’s pricing is the most competitive on this list, reflecting the lower labor rates in southern Vermont. Oil boiler replacements run 10-15% less than Burlington-area quotes, and heat pump installations are similarly discounted. The trade-off is a smaller team, which means longer wait times for non-emergency service calls during peak season (October-December). Emergency response is reliable — they maintain 24/7 availability and prioritize no-heat calls in winter. For homeowners in southern Vermont, they are the clear first choice.
- Service area: Windham, Bennington counties, southern Windsor County
- Certifications: VT Master Plumber/Heating, EPA 608, Mitsubishi certified
- Services: Oil boilers, propane, heat pumps, water heaters, chimney liners
- Emergency response: 24/7, average response 2-5 hours
- Average client rating: 4.7/5 (64 reviews)
- Maintenance plans: $149–$249/year
5. Mountain View HVAC — Rutland
Mountain View HVAC serves Rutland County and the Killington corridor, including seasonal properties that need winterization and de-winterization services. The team of 10 technicians handles oil, propane, and heat pump systems, with a growing specialty in servicing the Killington-area rental and second-home market. Their understanding of seasonal property maintenance — draining pipes, setting systems for vacation mode, remote monitoring setup — makes them particularly valuable for ski property owners who are not on-site year-round.
Mountain View has installed approximately 100 heat pump systems per year since 2022, primarily as supplemental heating in homes that retain oil or propane as their primary system. Their oil service department maintains about 1,500 accounts in the Rutland area. Clients praise their honesty in diagnostics — multiple reviews mention that Mountain View recommended repairs rather than replacement when the existing system still had useful life, saving homeowners thousands of dollars.
- Service area: Rutland County, southern Addison County, Killington corridor
- Certifications: VT Master Plumber/Heating, EPA 608, NATE
- Services: Oil boilers, propane, heat pumps, AC, seasonal property maintenance
- Emergency response: 24/7, average response 2-5 hours
- Average client rating: 4.7/5 (53 reviews)
- Maintenance plans: $149–$259/year
HVAC Installation Cost Comparison in Vermont
Understanding typical pricing helps you evaluate quotes. Vermont HVAC costs run 10-20% above national averages due to the short installation season, limited contractor pool, and the complexity of working in older homes.
| System Type | Equipment + Install Cost | Annual Operating Cost | Lifespan |
|---|---|---|---|
| Oil Boiler (standard efficiency) | $6,000–$10,000 | $3,200–$5,000 | 20–30 years |
| Oil Boiler (high efficiency) | $8,000–$14,000 | $2,600–$4,200 | 20–30 years |
| Gas Furnace (high efficiency) | $5,000–$9,000 | $1,800–$3,200 | 15–25 years |
| Cold-Climate Heat Pump (single zone) | $4,000–$7,000 | $600–$1,200 | 12–18 years |
| Cold-Climate Heat Pump (whole home, 3-4 zones) | $14,000–$26,000 | $1,400–$2,800 | 12–18 years |
| Propane Furnace | $4,500–$8,000 | $2,400–$4,200 | 15–25 years |
| Geothermal Heat Pump | $22,000–$38,000 | $800–$1,600 | 20–25 years (ground loop: 50+) |
After Efficiency Vermont rebates ($1,500–$4,000) and federal tax credits (up to $2,000), the net cost of a whole-home heat pump installation drops to $8,000–$20,000. At current energy prices, heat pumps pay back their incremental cost over oil in 5-8 years.

How to Choose an HVAC Company in Vermont
Beyond the rankings, here are the practical steps to vetting an HVAC contractor in the Vermont market.
- Verify licensing. Check the Vermont Office of Professional Regulation database for a valid Journeyman or Master Plumber/Heating license. For heat pump work, confirm EPA Section 608 certification. NATE (North American Technician Excellence) certification is an additional quality indicator but not required by law.
- Confirm insurance. Request certificates of general liability and workers’ compensation insurance. Any company sending technicians into your home should carry both.
- Get written estimates. A good HVAC estimate includes equipment model numbers, labor breakdown, permit fees, disposal of old equipment, and warranty terms. Compare at least two estimates for any installation over $3,000.
- Ask about heat pump experience. If you are considering heat pumps, ask how many systems the company installed last year and which brands they are authorized to sell and service. Manufacturer authorization (Mitsubishi Diamond, Fujitsu Elite, Daikin authorized) means the technicians have received brand-specific training.
- Evaluate emergency response. In Vermont, a heating emergency in January is a genuine crisis. Ask about 24/7 availability, average response time, and whether maintenance plan members get priority scheduling during emergencies. The difference between a 2-hour and 12-hour response time on a -15°F night is the difference between discomfort and frozen pipes.
- Check maintenance plan value. Most Vermont HVAC companies offer annual maintenance plans for $149-$349. These typically include an annual tune-up (which extends equipment life and catches small problems), priority emergency scheduling, and discounts on parts and labor. For oil systems, annual tune-ups are particularly important — a well-maintained oil boiler burns 5-10% less fuel than a neglected one.

Frequently Asked Questions
Should I replace my oil boiler with a heat pump in Vermont?
For most Vermont homeowners, the best approach is adding heat pumps while keeping the oil system as backup. Modern cold-climate heat pumps from Mitsubishi, Fujitsu, and Daikin operate efficiently down to -13°F to -15°F and can handle 70-80% of Vermont’s heating season. The oil boiler kicks in during the coldest stretches (typically 2-4 weeks per winter). This hybrid approach cuts annual heating costs by 30-50% while ensuring you never lose heat. Full replacement (removing the oil system entirely) is feasible with a well-designed, whole-home heat pump system, but requires careful sizing and a backup plan for extreme cold.
How much does a heat pump cost in Vermont after rebates?
A single-zone ductless mini-split costs $4,000–$7,000 before incentives and $2,000–$5,000 after Efficiency Vermont rebates and federal tax credits. A whole-home system (3-4 zones) runs $14,000–$26,000 before incentives and $8,000–$20,000 after. The exact rebate amount depends on system size, whether you are replacing an oil system, and your income level — income-eligible households may qualify for enhanced rebates that cover a larger share of costs.
How often should I service my oil boiler in Vermont?
Annually, every fall before the heating season starts. An annual oil boiler tune-up costs $175-$300 and includes cleaning the burner and heat exchanger, replacing the nozzle and oil filter, checking the draft and combustion efficiency, inspecting the chimney liner, and testing safety controls. This maintenance extends boiler life, improves efficiency by 5-10%, and catches small problems before they become mid-winter emergencies. Most HVAC companies in Vermont include an annual tune-up in their maintenance plan pricing.
What should I do if my heat goes out in January?
Call your HVAC company’s emergency line immediately. While waiting for the technician: keep interior doors open to distribute any remaining heat, run faucets at a trickle to prevent pipe freezing, use a space heater in one room (safely, away from combustibles) for warmth, and close curtains for insulation. If the house temperature drops below 50°F and the repair timeline is uncertain, drain pipes or have someone stay in the house to monitor. In Vermont, most HVAC companies with maintenance plans prioritize their plan members for emergency calls — this is the single strongest argument for paying for an annual plan.
Is central air conditioning worth it in Vermont?
Traditional central AC is generally not necessary in Vermont — the cooling season is short (6-8 weeks of truly warm weather), and many homes are comfortable with window units or no cooling at all. However, if you install ductless heat pumps for heating, they also provide air conditioning at no additional cost — the same unit heats in winter and cools in summer. This dual-function capability is one of the strongest arguments for heat pumps in Vermont, as you get AC as a bonus alongside your primary motivation (cheaper heating). Our closing cost calculator can help you budget for HVAC upgrades as part of a home purchase.
