South Burlington Weather and HVAC Load
South Burlington logs 6,960 heating degree days and 655 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here, and furnaces and heat pumps in South 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.

South Burlington Housing Stock
Census figures put the median build year in South Burlington at 1988, so a typical house here has about 38 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 60.1% of occupied homes, roughly 5,600 households. With a median household income of $97,229 and a median home value of $399,600, local labor rates come out above the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 4 hail days and 21 days with damaging thunderstorm winds in Chittenden County. 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.

- There's no natural gas service on your street
- The house heats with electric baseboard, oil or propane
- Your AC needs replacing, and you'd like cheaper heat at the same time
What Moves the Price
- Size in tons, and whether the unit is cold-climate rated
- Variable-speed (inverter) or single-stage compressor
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- A ducted system or a ductless mini-split
- Electrical panel capacity and wiring

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. Plan on a mechanical permit for most replacements in South Burlington; the contractor normally pulls it. Before you sign, ask each bidder for their 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
- Make sure the installer sized the system for your heating load, not only cooling.
- Where winters get cold, ask for a model on the NEEP cold-climate list.
- Ask your electric utility and state energy office what heat pump rebates are open right now.

Heat Pump Installation Questions from South Burlington Homeowners
How much is heat pump installation in South Burlington?

Between late spring and early fall. South Burlington averages 145 freezing nights a year, and heating calls spike from November through February.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
