- Permit and town inspection
- Haul-away of the old furnace
- Condensate line or pump
- Permit and town inspection
- Anything in writing
Same work, side by side
Estimate. What each quote would likely cost if it covered the same work as the most complete one.
B's low price comes from leaving work out. Add the permit, haul-away and condensate line and it lands close to A.

- Quote B. 50% up front is high. Most good crews take 30% or less.
Ask each company
Questions for A
Is the utility rebate already taken off the $8,400, or do I file for it?
Is the 2-year labor warranty in writing?
Can the install date move if it gets cold early?
Questions for B
Does $7,200 include the town permit and inspection?
Do you haul away the old furnace, and what does that cost?
Would you take 30% down instead of 50%?
Questions for C
Can you send that $7,800 in writing, line by line?
Is the town permit included?
What size furnace, and what's the labor warranty?
How the comparison works
Our proprietary tool analyzes every quote, then puts them all on the same rows: price, equipment, what’s included, permit, warranty, timeline and deposit.
The “same work” numbers are estimates, labeled that way. They show what each quote would likely cost if it covered everything the most complete one does.
Names, company names and addresses are removed. Only your ZIP is used, so prices match your area.
