This is a forced hot air system??
Not hot water or steam??
No Central Air??
Domestic hot water (for taps) not connected to "furnace"??
Will the tank need to be abandoned/removed??
$2000 to $5500, depending...
Jim, thanks for the Quick reply. As you can see I have no idea what
I'm getting into. If you questions were directed to asking if I know
how my current system works - my answer is I don't know. This is a
house I plan on buying and it has an old Oil furnace that I want to
upgrade to a Gas one. I've been told by my agent that there is a gas
connector available in the neighbourhood as this is one of the only
homes that hasn't been upgraded.
Can someone advised if worst case there is no Ducts and we were doing
an install from scratch - What would it cost?

With all respect, you don't have nearly enough info on this house.
Never mind what the agent has told you.
If it needs a gas line run from the street, that expense is extra.
If the system is hot water/steam and you want to change to
forced hot air (maybe with central air), the duct work install
will be a huge cost.
If the system is indeed forced hot air, the cost of conversion to
gas will be the least. If you do want central air added, that will
bump the cost up significantly. AND...you would have to see if
there is adequate electric service to support it.
Get a contractor to inspect the place with you and advise.
If you have to pay him for the trip, it will be worth it.
No one here can give you much of an answer beyond "$2000 to $5000, or
possibly even more". Here is how you can get a better answer:
- Find out if the house has a gas connection already. (If the gas pipe
is out in the street, it will cost you to have it run into the house.
If there are already gas appliances -- gas stove, etc. -- then you
don't have to run a new gas line.)
- Find out what the oil furnace provides: is it just home heating? or
is it home heating plus hot water for the house? And is there an air
conditioning built in with the furnace that you would want to replace
- Find out what kind of heating system it is: "forced air" with vents
in every room, or a steam or water based system with old fashioned cast
iron registers (or hidden-in-the-floor pipes, etc.); just look in the
basement at the furnace: if it has just smallish pipes and a chimney
connected to it, then it is water or steam. if it has big ducts (big
enough for a kid to crawl through) then it is forced air.
Then call a local heating and air conditioning installer, give them the
answers to the above, and ask for a ballpark estimate (which is all
they will provide without an on-site look). Explain that you are
considering buying the house and know nothing about heating systems.
Good luck with your new house. It takes a long time to learn all this
stuff, but owning a house is great...
You really need more information. Just a few points.
Furnaces heat air, boilers heat water. If it has ducts and hot air, you
have a furnace. If you have radiators or baseboard heat, you have a boiler.
Just because there is a gas line, it does not mean you can tap into it. The
gas company will give you that information. In my case, it would be $10k
just to bring the gas to my house. Yours can be 1k or 20k. Find out before
Gas may or may not be cheaper than oil. Check rates and do comparisons.
You may save more by upgrading insulation and windows. In some regions, gas
supply has been short and they are not taking on new customers.
Removing an oil tank can be expensive. If the tank is in-ground it can be
very expensive. This will vary according to any environmental laws in your
state. Oil can be pumped out cheaply and easily.
What about the hot water? Does that have to be changed also?
Get a local heating contractor to look at the job and guide you. Real
Estate agents often don't know much about this sort of thing.
