| 40 1,000 BTU of output | $2,000 – $6,000 |
| 55 1,000 BTU of output | $2,800 – $8,300 |

| 90 1,000 BTU of output | $4,500 – $13,500 |

Based on Annapolis pricing of $50–$150 per 1,000 btu of output.
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 Annapolis median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Straight equipment swap | Same tonnage, existing ducts and pad reused | $4,800 – $6,600 |
| Higher-efficiency replacement | Upgraded SEER2 tier, same configuration | $6,600 – $8,600 |
| Heat pump conversion | Electric heat pump replacing AC plus furnace or strips | $7,600 – $10,400 |
| Replacement with duct repair | Sealing, resizing or replacing failed duct runs | $8,600 – $11,700 |
| Ductless multi-zone | Three to four indoor heads, new line sets | $8,300 – $11,700 |
- • 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 Annapolis median for furnace replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Frequently asked questions
Does a furnace changeout need an inspection?
Yes in most jurisdictions. Combustion appliances are inspected for venting, combustion air and gas connections, and the permit is typically not closed until that inspection passes.
Is a high-efficiency furnace worth the extra cost?
It depends on how many heating hours the climate produces and the local fuel price. In cold climates the fuel saving usually repays the difference; in mild climates it often does not.
Do I need a permit for furnace replacement in Annapolis, MD?
In most jurisdictions this work is permitted and inspected. Requirements are set locally, so confirm the current application and inspection checklist with your building department before work starts.
How long does furnace replacement take?
1 day of work, 1-3 weeks including permitting and inspection. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are input rating in btu and the efficiency tier selected; condensing (90%+) furnaces requiring new pvc venting and a condensate drain; gas line resizing or a new sediment trap and shutoff.
