HVAC is an all-encompassing term that stands for heating, ventilation and air conditioning. It’s often used to refer to your home’s complete heating and cooling system, which includes:

  • Heating and cooling equipment, such as a furnace, heat pump, air conditioner or ductless mini-split
  • Ductwork
  • Indoor air quality products like air filters, air filtration systems, germicidal UV lights, whole-house humidifiers and dehumidifiers and fresh air ventilation systems
  • Thermostats and home zoning systems

While there are a variety of options for heating and cooling your home, these systems work similarly by:

  • Using a source of fresh air inside or outside your home for combustion or transferring heat.
  • Using a filter to trap particles and allergens.
  • Distributing heated or cooled air through ductwork or straight into a specific room.
