The costs associated with a central heating and cooling system can depend on many things, such as the size of your home, the type of boiler you use, and the quality of the products you are installing.
A four-bedroom home with two living spaces and a gas boiler can cost between $14,000 and $18,000 with some wiggle room. A diesel boiler central heating system in a home of the same dimensions may cost between $19,000 and $25,000.
