Burlington Weather and HVAC Load
NOAA's 1991-2020 climate normals put Burlington at 6,960 heating degree days and 655 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Burlington put in far more hours than the air conditioner. Count on roughly 145 nights below 32°F and 8 afternoons past 90°F in a typical year. Snowfall averages about 88 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 70,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Burlington Housing Stock
Half the homes in Burlington were built before 1957 (Census ACS median), so the typical house is about 69 years old. Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. Owners live in 39.8% of occupied homes, roughly 7,000 households. The median home value is $400,200, and median household income is $68,854. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Chittenden County show 4 hail days and 21 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

Vermont Permits, Efficiency Rules and Rebates
Vermont falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Expect the contractor to pull a mechanical permit for a replacement job in Burlington. If a bidder suggests skipping it, move on. Also ask for a Vermont license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- For a steam system, hire a contractor who works on steam regularly.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- A combi boiler frees up space and replaces your water heater.
