The normal setting is on "automatic" with the fan's cycle being controlled by the temperature in the room. However, if your home is equipped with an air cleaner (media or electronic) or you wish to keep a continuous flow of air, switch the setting to "on". Remember, central air cleaning devices only work when the furnace is circulating air. If you wish to get the most from your air cleaner, you should keep your thermostat setting to "on".

The arrow should point in the same direction as the flow of air. In most cases, it will point towards the furnace and should fit between the return air part of the system and the furnace. The filter screens out the dust and other impurities before the air is warmed in your furnace and distributed through the duct system.

An air conditioning system consists of two parts: an outdoor unit (where liquid refrigerant is contained) and an indoor coil (where the refrigeration is pumped into). As the air moves across the air conditioning coil (usually located on top of the furnace), the refrigerant removes the heat from the air as well as the moisture by condensing it on the cold surface of the coil. In this way, the air conditioner not only cools but also dehumidifies the air. Virtually any system can have air conditioning hooked up to it provided it is a forced-air system. In cases where there isn't a forced-air system, Apollo has a unique "mini-duct" air conditioning system to cool an entire home. Apollo specializes in this "mini-duct" AC system to help our customers with older homes stay cool in the summer!

S.E.E.R. is the standard measurement of air conditioning efficiency established by the U.S. Department of Energy. Higher S.E.E.R. ratings translate into greater energy efficiency, which means lower summer cooling bills. So the higher the S.E.E.R. rating, the more money you save. If you air conditioner is more than 10 years old, it's probably an 8.0 S.E.E.R. system. The newer systems out today are 12.0-14.0 S.E.E.R. systems. If an estimated annual bill for an 8.0 S.E.E.R. system were $1,000 (for example), it would only be $615 for a 13.0 S.E.E.R. system - a 38% savings!

Every home seems to have at least one room that's always too hot or too cold. The problem is due to standard heating and cooling systems that pump climate controlled air to all your rooms at once. Rooms furthest from your heating and cooling units get less warmed and cooled air. Our solution: Zoning. Zoned heating and cooling systems with automatic dampers and extra thermostats heat and cool specific "zones" without affecting the temperature in the rest of your house.
