Question DetailsAsked on 9/4/2013

i need cost for a 3000 sq ft natural gas furnace installed to hook up to existing hot water baseboard

we have natural gas pipes on our road and its about 100 feet to the road and we will need a hookup there also. We live in east Quogue, NY. We also would like a more efficient hot water system connected. Our oil furnace is from the 60s.

You will need to check with your natural gas provider if they connect at the road, or install to your house, and get cost from them for that. Usually the utility installs the service line to the house and provides the meter, and then your plumber connects from the meter to the appliances. Utility service install cost can range from zero (they will recover the cost in consumption charges over the years) to as much as $25/LF - so up to $2500 or so in your case. Commonly runs around $5/LF plus about $500 meter and hookup, so more like $1000 commonly for your case, but check with your utility. You can cut your install cost by digging the ditch to their specs yourself - usually 12-24" deep required, depending on your locale.

For a normal piping install to water heater/furnace from the meter by a plumber, about $300-600 depending on distance and ease of access (open basement floor joists running same direction as pipe easiest/cheapest, finished ceilings with joist running crossways to pipe run the toughest/most expensive), plus possibly $250-400 repair cost to ceilings needed to be opened up for connections/running pipe if they are finished.

Assuming your baseboard heating system is working fine, then furnace replacement only probably about $50-500 furnace disposal depending on whether asbestos insulated or not (could be either if from 60's), and from $2000 absolute cheapest to as much as $7000 for highly energy efficient furnace, installed - normal range is $3-4,000.

Another thing you did not mention is oil tankand oil lines removal and disposal and cleanup of any spills - from bare minimum of about $500 with zero oil spills (almost unheard of) to tens of thousands if tank has been leaking over the years continuously. Nationwide average removal cost about $2500-5000 including about 5-10 foot pit to remove contaminated soil.
