Do air conditioners use gas or electricity?

If your house has central air conditioning, cool air probably flows through the same ducts that heat does and is regulated by the same thermostat. Air conditioners use electricity. Most home heating systems use gas or fuel oil; other systems use electricity.
A.

Do you have to have a furnace to have central air?

You don't have to deal with two separate systems, a furnace and a central air conditioner. With a heat pump, there's only one system to install, maintain, repair or replace. Unlike with a furnace and central air conditioner, you don't have to heat and cool rooms you don't use.
  • How much is ductless air conditioning?

    For this discussion, we will consider the costs of installing a ductless or "split" air conditioning system in a 2000 square foot home. The average price for the equipment and installation of a system sized appropriately for the cooling needs of a home of this size ranges $1800-$7000.
  • What is central heating and air?

    A central heating system provides warmth to the whole interior of a building (or portion of a building) from one point to multiple rooms. When combined with other systems in order to control the building climate, the whole system may be an HVAC (heating, ventilation and air conditioning) system.
  • What is the furnace filter?

    The main purpose of a furnace filter is to protect the blower fan from all the dust, hair and other gunk the return duct pulls in. While it will also help the quality of your inside air (as it is removing contaminants from being recirculated), its job is not to actually clean your air as many people believe.
B.

Are furnace and air conditioner filters the same?

As we mentioned in our blog about replacing your furnace and air conditioner at the same time, your heating and cooling system share the same air handler. And since that's the same area where your air filter is housed, both systems share the same filter as well!
  • Can you put a wet filter in your air conditioner?

    Remove it from the unit, rinse it off with water and allow it to air dry completely before putting it back in. Sliding a wet filter back into your air conditioner is just asking for ice formation and other issues, and trying to wipe the filter dry is likely to damage its delicate surface.

  • What is the purpose of the condenser?

    In systems involving heat transfer, a condenser is a device or unit used to condense a substance from its gaseous to its liquid state, by cooling it. In so doing, the latent heat is given up by the substance and transferred to the surrounding environment.
