Costs & Choosing a System

These guides are for the decision before the install: which system fits the house, and what it will cost. Every number comes from the same published price list our quotes use. A central heat pump starts at $7,500 for 3 tons, a one zone ductless mini-split at $4,600, an 80% gas furnace at $3,300 and a central air conditioner at $6,900, all installed.

The price is only half of the choice. Ducts or no ducts, a gas furnace you want to keep or not, one temperature for the whole house or rooms on their own settings: these decide the system, and the system decides the price. The guides walk through the same questions we ask at an in-home assessment, with real installs from our city pages as examples.

When you are ready for a number for your own house, the assessment is free, and the quote is itemized line by line before any work starts.

Which guide to read first

• What a heat pump costs in 2026, if you need a number: the four lines that move a quote (system size, a first install or a replacement, the size of your home, and whether the furnace is replaced too), with three worked examples from the price list.
• Mini-split or central heat pump, if you are not sure whether your house needs ducts: how ducts, zones and space decide it, and what each one looks like day to day.
• Heat pump or gas furnace, if you heat with gas today: the three setups we install (all electric, a heat pump added to a furnace, a furnace with central air) and who each one suits.

Before the assessment it helps to think about four things: which rooms bother you most and in which season, whether you want the whole house at one setting, whether you have gas and a furnace you want to keep, and which walls or ceilings you would not want a unit on.
