What's the best HVAC system for Williston's climate?
The best HVAC system for Williston depends on your specific home and budget. Given some of the coldest winters in the Northeast, with temperatures regularly below -10°F, we typically recommend high-efficiency systems with SEER ratings of 16+ for cooling and AFUE ratings of 96%+ for heating. Heat pumps are increasingly popular in VT as they handle both heating and cooling efficiently. Our technicians will match the right system to your home's needs.
How can I tell if my HVAC ducts are leaking in Williston?
Signs of leaky ductwork in Williston homes include uneven temperatures between rooms, higher-than-expected energy bills, excessive dust near vents, and a system that runs constantly without maintaining the set temperature. Leaky ducts can waste 25–30% of your conditioned air. Our Williston team offers professional duct sealing that typically pays back in energy savings within 1–2 heating or cooling seasons.
