How Does an HVAC System Work?

If you’re like most property owners in Meridian, ID, the HVAC system in your home or commercial building was probably a significant investment. “HVAC” is short for “heating, ventilation and air conditioning,” and in general, these systems contain some or all of the following components:

  • Furnace or heat pump
  • Evaporator coil
  • Condensing unit
  • Refrigerant lines
  • Vents and ducts
  • Thermostat

These pieces of equipment work in concert to help ensure that the interior of your home or place of business remains at a comfortable temperature.

How Do These Components Work Together in Your Home?

As the central command unit of your property’s HVAC system, the thermostat controls the other components. The other main components include the furnace, which is designed to convert fuel or electricity into heat. Evaporator coils condense humidity from the air while condensing units act to cool air in conjunction with the use of a refrigerant. The ceilings, walls and crawl spaces of your building contain HVAC air ducts. These ducts carry warm air from your furnace and cold air from your air conditioner. Vents are the points through which temperature-controlled air enters living spaces. Vents should be kept dust-free, and ducts must be insulated and well-sealed.

Common HVAC Issues

For your HVAC system to work properly, certain issues may eventually need to be addressed. Clogged filters are among the most common and easily fixed HVAC problems. Dirty filters put an enormous strain on your HVAC units because your equipment has to work much harder to circulate warm or cool air. Other common issues include:

  • Dirty and dusty HVAC components
  • Equipment that makes clanking or squealing noises
  • Components that continuously cycle
  • Hoses that leak
