A central air conditioner cools with an outdoor compressor and condenser coil connected to an indoor furnace fitted with an evaporator coil. ... As the air handler pushes warm air across the coil, the refrigerant absorbs so much heat from the air that it turns into vapor.

If everything is working properly, your AC should never need refrigerant. In fact, a central air conditioner should never need refrigerant added unless there's a refrigerant leak.

HVAC control system. HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state.

HVAC Zoning System. An HVAC zoning system (also referred to as “zoned HVAC”) is a heating and cooling system that uses dampers in the ductwork to regulate and redirect air to specific areas of the home. This allows for the creation of customized temperature zones throughout the home for increased comfort and efficiency ...

Portable air conditioners work basically the same way as built-in air conditioning: sucking in warm and humid air, cooling and dehumidifying it and blowing it back into the room.

Essentially, a PTAC unit is a self-contained heat pump version of your central air conditioning system. ... In cooling mode, the compressor super-heats the refrigerant, which runs through the evaporator coils and draws heat out of the room.

A ductless mini-split air conditioner works like a regular central air conditioner but without the ducts. How's that possible? The indoor unit blows warm air from your home over cold evaporator coils. The refrigerant running through these coils absorbs the heat from the air and brings it to...

Primary HVAC equipment includes heating equipment, ventilation equipment, and cooling or air-conditioning equipment. Central HVAC systems locate away from buildings in a central equipment room and deliver the conditioned air by a delivery ductwork system.

See Also: Air Filters The short answer is, no, they're not all the same. In fact, there are many different types of air filters available and choosing the right one can make a real difference in the lifespan of your HVAC system. ... You see, the higher the MERV rating, the more the filter restricts air flow.

The refrigerant used in most air conditioners is different than what is used in most refrigerators. Compressors are designed for a particular refrigerant. ... Finally, the capacity of the air conditioner (BTU's per hour) will be very different from the refrigerator.

While air conditioners are used to cool air in a designated area, dehumidifiers are responsible for pulling moisture out of the air. The catch is, while an air conditioner is circulating warm air and pushing cold air throughout a home, office, or other structure, it does remove some moisture from the air it treats.

Yes, yes, yes – an HVAC tune-up is worth the money. Just like your vehicle, your HVAC system is a complex piece of machinery that gets a lot of “mileage.” It's full of critical and moving components, that experience wear and tear over time.

The condensing unit aka “the air conditioner” is found outside the home. A condenser's major components are a compressor and a condenser coil. Instead of blowing conditioned air throughout the home like the air handler does, an air conditioner's main function is to remove heat from within the home.
