Cost by system scenario

Equipment type, tonnage and whether the ductwork or electrical has to change move HVAC pricing more than brand does. Every row is priced against the Bangor median.

ScopeWhat it includesTypical installed cost
Straight equipment swapSame tonnage, existing ducts and pad reused$3,500$4,800
Higher-efficiency replacementUpgraded SEER2 tier, same configuration$4,800$6,300
Heat pump conversionElectric heat pump replacing AC plus furnace or strips$5,500$7,500
Replacement with duct repairSealing, resizing or replacing failed duct runs$6,300$8,500
Ductless multi-zoneThree to four indoor heads, new line sets$6,000$8,500
  • Correct sizing comes from a load calculation, not from matching the old unit's tonnage — an oversized system short-cycles and costs more to run.
  • Line-set replacement and electrical disconnect work are common add-ons on a swap that was quoted as straightforward.
  • Refrigerant transition rules mean older-refrigerant equipment is no longer a like-for-like replacement in most markets.

Basis: Each scope is priced as a multiple of the modeled Bangor median for mini split installation, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Frequently asked questions
