1 Replacing the gas line running to the house costs $3,000 to $7,000 in most cases (labor and materials). Many people mistakenly think the gas company pays for this repair, but the homeowner is responsible.  If the appliance itself is faulty, youâll have to replace it.
The cost for replacing a standard gas boiler is about $4,000. A high-efficiency model costs about $7,500. This cost estimate usually includes removal and disposal of the old unit, as well as all necessary lines, ducts and wiring needed for the new system to run properly. The average cost for this is $1,000 to $1,500, though your utility company may offer a discount to win you over as a customer. 2  A contractor will have to hook up the gas lines between the meter and your house. 3  This normally costs around $500 to $1,000.
