Your Heating Ventilating and Air Conditioning or HVAC system is vital to your home comfort all year round. Your HVAC system will keep you warm in the winter and cool in the summer. However many don’t know what makes up a HVAC system and what each component does to keep you home temperature comfortable. Steve’s Heating & Air will share the different components of the HVAC system and how they work to better help you troubleshoot any problem or system failures in the future.
The thermostat is the one component that every person is the most familiar with. It is located inside the home in a convenient place that gives control to the HVAC unit. This will give the ability to control the heating and cooling of the home or building. The thermostat will also control the temperature of the room. When it gets too cool or too hot, the thermostat will trigger the heat exchangers or the evaporator coils; the condensation that will either circulate warm or cool air into the building.
The furnace is one of the major components of the HVAC unit. It is also one of the largest and requires a lot of space. The furnace will be located either in the attic, basement, cellar or a special closet meant to house the furnace. The furnace is designed to pump heat into various rooms in the home or building. The furnace will either use natural gas, oil, coal, propane or electricity to create the heat.
Application of Heat Exchangers
The heat exchanger is a component inside the furnace. The heat exchanger’s job is to activate the furnace when the thermostat senses the temperature dropping inside the home. The heat exchangers pulls the cool air in, heats this cooler air and then re-circulates the warm air through the air ducts.
Evaporator Coils Function
The job of the evaporator coil is to cool the warm air it pulls in during the summer time in order to lower the temperature inside the home or building. The evaporator coils are located on the outside of the enclosure of the furnace’s exterior. Like the heat exchanger, the evaporator coils will push the cool air into the air ducts thus cooling the home.
How a Condenser Works
The condenser is connected to the evaporator coils, which are installed by the contractor on the outside of the home or building. The condensing unit is filled with the refrigerant gas that turns warm air into cool air.
What Are Refrigerant Lines?
The refrigerant lines carry the refrigerant or coolant into the condensing unit that changes it from gas, and then returns it to the evaporator coil that changes it back into liquid. The lines will be either made of copper or aluminum which is resistant to the heat or cold that is produced.
Air Ducts or Ductwork Design
The ductwork or air ducts is the system that the cool or warm air travels through in taking it to the various room of the home or building. The ducts are made of a lightweight aluminum, or occasionally flexible plastic, polyurethane or fiberglass. Did you know that even fabric can be used for the ductwork system?
Purpose of Vents
The vents are the outer part of the air ducts. They are designed to direct the air in a certain direction. They are usually made of a high and low temperature safe metal.
