The lifespan of new equipment exceeds that of older systems. Older furnaces generally last between 10-15 years, and olderair conditioners last 10-12 years. New equipment has a longer lifespan of 15-25 years for air conditioning systems. Many new furnaces have a lifetime warranty.

A furnace or air conditioner that is more than 12 years old may not have the energy efficiency you want. Replacing an inefficient system with a high-efficiency system can help you save up to 50% on energy costs, saving you money on your heating and cooling costs and improving home comfort.

Factors, such as the size of your home, when the home was built, type of ductwork, and insulation, influence the size of heating and air conditioning systems. At RJS, we provide a thorough in-home evaluation to determine your needs and recommend the right size furnace or air conditioner for your home.

Seasonal Energy Efficiency Rating (SEER) is a rating system for the energy efficiency of heating and cooling equipment. Equipment with a higher rating means better energy efficiency and lower energy costs.

Considering the rising energy costs, a furnace with a 92% efficiency rating is ideal for home heating. A furnace with an 80% efficiency rating may cost less initially, but you will get a lower return on investment.

There are many ways to increase energy efficiency at home, including:

  • Inspecting filters monthly and changing when needed
  • Having your system cleaned and tuned twice yearly
  • Keeping interior doors open two inches or more in rooms without return vents
  • Checking that furniture is not blocking any duct vent registers
  • Making sure ductwork is sealed
  • Insulating the attic and ductwork
  • Replacing old, inefficient equipment with a new heating or air conditioning system
  • Looking for ENERGY STAR heating and cooling equipment
  • Turning off lights and electronics in unoccupied rooms
  • Replacing light bulbs with compact fluorescent bulbs

The fan on the system draws indoor air through the return vents in the home and moves it through the ducts that run to the air handler in the system. The air is conditioned and returned into the space through the supply vents located in the walls, floors, and ceilings.

Yes. Dust, pet dander, and other particles build up in the duct system. From there, the particles travel through the air in your home. This can cause allergy and asthma symptoms and may put added strain on your equipment.

Cleaning and maintaining your furnace or air conditioner helps maximize the useful life of the equipment. Lack of maintenance is the leading cause of equipment breakdown and the need for replacement parts.
