What is the Most Important Part of an HVAC System?

The heat exchanger is arguably the most important part of an HVAC system for air cooling. It absorbs heat, warms cold air, and then blows warm air through ducts and vents into your home. It is activated when the thermostat activates the oven and combustion causes the heat to increase. The fan motor powers a fan that causes warm air from the heat exchanger to enter your home through ducts and vents.

The variable speed motor continues to blow until all the warm air from the heat exchanger and ducts has entered the rooms of the house. The combustion chamber, or burner, is where the furnace combines air and fuel. In some high-efficiency gas ovens, there is a second combustion chamber to capture and compress carbon monoxide and unburned fuel before igniting it. The condenser coil or compressor cools your home by releasing heat from inside to outside air.

Your evaporator coil is essential for any air conditioner or heat pump as it compresses and condenses refrigerant as a fan blows air over it, cooling it down and dispersing heat. The thermostat contains temperature sensors and user controls that allow you to control when the air conditioning system is turned on and off. If you need help optimizing your smart thermostat for each season, schedule a biannual tune-up of your heating, ventilation and air conditioning system. Some air conditioning systems include several thermostats throughout the house, each of which controls a defined space or “zone”.

Since ducts cover much of land, especially in insufficiently isolated areas such as attics and basements, they can lose between 20-30 percent of energy produced by an AC system. Your AC system then sends liquid refrigerant through an aluminum or copper line or tube to evaporator coil which changes refrigerant into vapor state that absorbs heat and lowers home's temperature. The fan in AC system blows hot air out of home through return ducts onto evaporator to cool it down then distributes cold air through ducts into rooms of home; this process repeats over & over again to keep home cool & comfortable. The ventilation grilles are also important components of an AC system as they remove moisture from air to prevent dust mites & other allergens from thriving; they automatically release air from ducts too.

To save energy & avoid problems with climate system, you should keep fallen leaves, grass clippings, dirt & other debris away from condenser; AC system brings refrigerant to series of small nozzles/expansion valves & these valves spray liquid refrigerant so it can evaporate from liquid to gas faster; indoor air pollution is common problem in homes but AC system can help keep indoor air clean.
