To install the most efficient HVAC system in your household, a detailed inspection should first be performed by your installation contractor.

The inspection by your contractor should include, as a minimum, the inspection of your home’s ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil.

How long will my system last?
Maintenance and service play a key role in the lifecycle of a heating or air conditioning system.

If all recommended maintenance and service actions are taken, it is believed that an air conditioner should last 12-15 years and a gas furnace should last from 20 to 25 years.

How much will my new air conditioning system cost?

That depends. There are many factors that must be considered. These include:

• The efficiency of the equipment
• The size of your home
• Is the ductwork installed and in good condition?
• Do you need a thermostat or electronic air cleaner?

In most cases, replacing your whole system, including both indoor and outdoor components, will result in a more efficient, longer-lasting system but will also cost a little more.
