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 New Rochelle median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Straight equipment swap | Same tonnage, existing ducts and pad reused | $4,600 – $6,200 |
| Higher-efficiency replacement | Upgraded SEER2 tier, same configuration | $6,200 – $8,100 |
| Heat pump conversion | Electric heat pump replacing AC plus furnace or strips | $7,200 – $9,800 |
| Replacement with duct repair | Sealing, resizing or replacing failed duct runs | $8,100 – $11,100 |
| Ductless multi-zone | Three to four indoor heads, new line sets | $7,800 – $11,100 |
- • 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 New Rochelle median for mini split installation, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
