Ductless mini-split systems are the most common AC installation we do for Vermont homes without existing ductwork. One outdoor unit, one to five indoor units, independent zone control. The same system heats in winter. No ductwork required.
Central air conditioning uses existing ductwork to distribute cooled air throughout the home. If you have ducted forced air, central AC is often the most economical whole-home cooling solution. A heat pump replacing a furnace provides central AC as part of the same installation.
Burlington's average summer high is now 80°F, with 17+ days above 85°F annually. Homes in direct sun,
older homes with poor insulation, and anyone with health sensitivities to heat or humidity benefit significantly
from air conditioning. The humidity is often the bigger issue than the temperature - Vermont summers can be
quite humid, and a properly operating AC system dehumidifies as it cools.
For a ductless system, $3,500–$5,500 for a single zone; $8,000–$14,000 for a multi-zone whole-home
system. Central AC through existing ductwork runs $4,000–$8,000. These costs are reduced when cooling is
part of a combined heat pump installation since you're installing one system for both functions.
