Quincy's housing stock heats with boilers far more than most of the country, and boilers cost roughly twice what a comparable furnace does to replace. Steam systems — common in the region's pre-war stock — need installers who genuinely know steam, a shrinking pool that shows up in the price.
Sizing runs about one ton of capacity per 500–600 sq ft, and price follows capacity. On mini-splits the lever is zone count: each zone adds a head, line set, and electrical work, which is why a three-zone system costs more than triple a one-zone — and why an honest installer sizes the system to the house rather than the brochure.
The same condenser can be a cheap job or an expensive one depending on what it connects to. Sound existing ducts keep a central-AC swap at the low end; leaky or absent ones push the money into sheet metal. That's the calculation that makes ductless mini-splits competitive in the region's older homes.
Mass Save's whole-home heat-pump rebate ($2,650/ton, up to $8,500) and 0% HEAT Loan (to $25,000) can move a heat pump from the expensive option to the competitive one. Compare systems on net price after incentives — and make sure the quote states which rebates the installer is assuming.
