A: Even if your heating & air conditioning system was built to go the distance, it's got to be maintained in perfect condition, just like your car. A properly maintained system will last longer with fewer breakdowns and save money every month through lower fuel bills.

A: The average life of a gas furnace is 15 years. The average life of an air conditioner is 12 years. Regular maintenance helps prolong the life of heating and air conditioning systems and keeps them operating as designed.

A: Although your present furnace or air conditioner may be working, if it is more than 12 years old you should consider replacing it with a new high efficiency system. A new heating and air conditioning system could save up to 50 percent on energy costs. While these products save you money on your utility bills, they also offer a better degree of comfort within your home.

A: A boiler uses oil, gas or electricity to generate hot water and in some cases steam, which is piped to baseboard radiation systems on the perimeter of the house. A furnace burns oil or gas to heat up air which is forced by a fan through a large ducted system and blown through registers in various parts of the house. Generally speaking, a cast iron boiler for a baseboard system has more than twice the life expectancy of a furnace for a hot air system.
