Central air conditioners circulate cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills)

carry cooled air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers.
Air conditioners help to dehumidify the incoming air, but in extremely humid climates or in cases where the air conditioner is oversized, it may not achieve a low humidity. Running a dehumidifier in your air conditioned home will increase your energy use, both for the dehumidifier itself and because the air conditioner will require more energy to cool your house. A preferable alternative is ade humidifying heat pipe, which can be added as a retrofit to most existing systems.

Important specifications to consider when searching for industrial chillers include the total life cycle cost, the power source, chiller IP rating, chiller cooling capacity, evaporator capacity, evaporator material, evaporator type, condenser material, condenser capacity, ambient temperature, motor fan type, noise level, internal piping materials, number of compressors, type of compressor, number of fridge circuits, coolant requirements, fluid discharge temperature, and COP (the ratio between the cooling capacity in RT to the energy consumed by the whole chiller in KW). For medium to large chillers this should range from 3.5 to 7.0, with higher values meaning higher efficiency. Chiller efficiency is often specified in kilowatts per refrigeration ton (kW/RT).

There are a number of different types of AC units and air conditioner maintenance will depend on the type of unit you own.

Another important part of maintaining your AC unit is scheduling an annual air conditioner maintenance service—ideally before the cooling season begins—in order to make sure it is working as efficiently as possible. Aire Serv Total Comfort Tune-up will ensure that your air conditioner is in tip-top working shape and that it will last for years to come. Plus, our experts at Aire Serv can address smaller problems that could grow into larger and potentially costly issues in the future.
