What we see in Newmarket
- Older homes downtown: limited duct space and older wiring. Ductless heat pumps are a clean way to add cooling and extra heat.
- 1970s and 80s homes: furnaces on their second or third replacement, original ductwork, and central AC added later with small upstairs ducts.
- Newer homes: builder-grade furnaces, ACs and humidifiers approaching replacement age.
