What a new system costs, and how to pay for it
The honest answer is that it depends on your house, and anyone who quotes you a firm number over the phone is guessing. Here is what actually moves the price, why two quotes for the same house can be thousands apart, and how financing works if you would rather not pay it all at once.
What actually moves the number
You do not have to pay for it all at once
A full system replacement is one of the larger bills a house hands you, and it rarely arrives at a convenient moment. Financing is available on bigger jobs, so ask Steve about it when he quotes the work. He will walk you through the options at your table alongside the number itself, so you can see the monthly cost next to the job instead of guessing at it later.
Steve prices the job himself and explains every line before you decide. There is no call-center markup, no commission on the sale, and no pressure to buy more system than your house needs.
“Steve is my hero! He showed up on time, explained my problems with the gas line, fixed it all for a SUPER price in 2 hours! I had 2 other bids from well known companies in the Wood River/Alton areas and they were $1200 higher than Janssen. Steve is the nicest guy, honest, and likes helping people. Call him, you will thank me later.”Tracey B. · Google

How to read any quote you get
Ask what size and why
A good quote can tell you the size it landed on and the reasoning. If nobody measured anything, be careful.
Ask what is actually included
Furnace, condensing unit, A-coil, thermostat, duct work, permits, haul-away. Two quotes rarely include the same list.
Ask who does the work
At Janssen the owner who quotes it is the one who installs it, which is not how most companies your size work.
Ask about the monthly cost
Between financing and what a more efficient system saves on bills, the sticker is only half the picture.
Answers before you call
It depends on the size your home needs, the efficiency you pick, and the shape of your ductwork, so an honest number takes a look at the house. Steve quotes the full system himself, explains every line, and never invents a figure to get in the door.
Yes. Financing is available on larger jobs like a full system replacement. Ask Steve when he quotes the work and he will walk you through the options at your table.
Usually because of what is included and who is quoting. National brands build call-center and commission margin into the price. Steve quotes it himself, so that layer is not in the number.
Yes, and he is glad to. Bring the quote and he will tell you honestly whether the size, the scope, and the price look right for your home.
