What Property Owners Need to Know About How HVAC Systems Work

If you’re a property owner, you know that a quality HVAC system is necessary due to frequent changes in temperature. Whether you have residential or commercial property, knowing how your HVAC system functions is key to maintaining indoor air quality and consistent temperature. Read on to learn the basics about how HVAC systems work.

What are the main types of HVAC systems?

The way your HVAC system functions depends on what model you have. Here’s a brief rundown of the most common systems you’ll find:

  • Forced air systems: One of the most efficient HVAC systems is the forced air system. It moves hot or cold air through ducts using a fan or blower.
  • Radiant systems: These systems can only be used to heat a building. They heat the floors, walls and ceilings of interior spaces. They’re also used to transport hot water to heat radiators that then distribute heat throughout the interior.
  • Gravity systems: Gravity causes cold air to fall and warm air to rise. This system is only used for heating, and it’s typically placed in a basement.

What are the main components of an HVAC system?

Although there are various models of HVAC systems, they have a few differences between their components. Many systems have the following components:

  • Furnace: Every HVAC system has a furnace. It uses oil or natural gas and a heat exchanger to heat the air. In a house, the furnace is usually in the basement, attic or in a small closet space.
  • Air conditioner: This component cools the air using electricity and coolant. It’s usually located outside of a building and sends cold air inside while pulling the hot air outside.
  • Ductwork: Ducts take the air from the furnace or air conditioner and send it throughout the building. You’ll find ductwork in the walls, floors and ceilings.
  • Thermostat: This component is the command center for your heating and cooling system. It’s where you set your desired temperature, and it contains a sensor to make sure the air nearby maintains your temperature settings.

How do you control your HVAC system?

You control your heating and cooling systems with the thermostat. This essential piece of equipment measures air temperature and adjusts the settings of your system accordingly. You manually set the temperature and the thermostat turns the system on or off to maintain a consistent temperature inside the building.

What do smart thermostats do?

Smart technology has changed the game when it comes to heating and cooling your home or business. It makes it more convenient to control how your HVAC system functions, allowing you to set the perfect temperature using any wi-fi equipped device. If you’re out, you’re able to get the temperature just right before you return home, and it keeps your system from using too much energy while you’re away.

Understanding how HVAC systems work will help you maintain clean air and comfortable temperatures at your property. Regular maintenance and inspections ensure your equipment works whenever you need it.
