What is HVAC

Don’t feel guilty if you don’t know what HVAC stands for—or how to pronounce the abbreviation (h-vac). Not many people know how an HVAC system supplies indoor air and maintains the environment inside their home. While it makes sense to leave installation and repair services to professional technicians, understanding the basics of HVAC can help you consider your options and save money.

What is HVAC, anyway?

HVAC stands for heating, ventilation, and air conditioning. Nearly every modern home, office, and industrial building has an HVAC system designed to regulate temperature and maintain indoor air quality, using components such as:

  • Furnaces
  • Compressors
  • Heat exchangers
  • Evaporator coils
  • Condensing units
  • Refrigerant lines
  • Air conditioners
  • Whole-home ventilators (fans)
  • Ductwork
  • Vents
  • Thermostats


Homes can be heated by gas or propane furnaces or water systems with boilers that use gas, oil, or fire. Depending on the system, heat is distributed through the ductwork, vents, or radiators. Some homeowners choose to install radiant floor heat systems as a second heating source.


Ventilation systems use fans, ducts, and vents to circulate the air throughout your home and provide each room with fresh oxygen for safe breathing. You can open your windows to increase air flow naturally, but that’s not an ideal solution in the winter months. Ventilation systems include bathroom and stove exhaust fans that carry out moisture and smoke to prevent mold and mildew growth. Filters, dehumidifiers, and humidifiers also improve the air quality in a home.

Air conditioning

Apart from just a window or wall A/C unit, most homes have a whole-house air conditioning system. Air conditioning can come in two forms: split systems and packaged systems. Split systems use an outdoor and indoor unit to cool the home; packaged systems come in an all-in-one, compact unit.

HVAC tips

Depending on the efficiency of your units, the size of the system in relation to your home, your local climate (in Minnesota, that’s a no-brainer), and how much you use it, the average monthly electric bill in the summer and winter can be well beyond a hundred dollars.
