The Basics of HVAC

Our heating, ventilation and air conditioning, also known as the HVAC system, keeps us comfortable all year round. Without it, our homes would not be as pleasant to live in. If you live in a hot climate then having a closed off house without HVAC may as well be a sauna while a cold climate would cause your house to conduct a freezing temperature all day.

In this article, we will discuss the basic properties of HVAC so that you can better understand how it works. Read on to learn more!

The Furnace

The furnace comprises most of the space involved for an HVAC system. You will typically find it in the basement or ground floor inside a tiny room used for nothing else.

The furnace conducts heat via the air ducts of your home. Without this component, your heating system would not function at all.

The furnace also contains a device called the evaporator coil. The coil contains a fluid known as a refrigerant and is designed to send cool air through the air ducts instead of hot air.

The Condensing Unit

If you’ve ever seen a funny-looking box outside a house, that’s probably a Condensing unit.

The job of a condensing unit is to take the hot air out of your home and deposit it outside. The process allows the evaporator coil in your furnace to leave cold air inside without overheating.

Without the condensing unit, your evaporator coil would start to heat up and wouldn’t be able to cool your house anymore.

The furnace and condensing unit are connected with metal tubes called refrigerant tubes.

The Thermostat

You’re likely familiar with the thermostat already as that is the device inside your house where you will program the temperature you want.

The thermostat is usually placed in the wall unless it is a standing thermostat. You will have a remote control that allows you to set the temperature as well as control any other features that your HVAC system has to offer.

The heat pump is generally a part of the thermostat and works from within the entirety of the HVAC system. It is the motor that controls whether warm air will be pumped out of the house or into the house.

If you listen to the noise coming from your thermostat, that will be the heat pump working its magic.

These are the basic components of your HVAC system. Now you know what you need and what each part should do. So, get out there and make your home ready for spring!
