We monitor every system through its first winter. These are real bills and meter readings from southern Maine homes.
01Featured project
An 1880s connected farmhouse burning 1,500 gallons of propane a year. We sealed the attic, then installed one ducted heat pump and two ductless heads. The old furnace stays as backup.

Hot water dropped from 4,200 kWh to 1,450 kWh a year. Installed in four hours.
Costs use $3.79 per gallon of oil, $3.45 per gallon of propane and $0.27 per kWh so homes compare on the same prices.
