HVAC is short for heating, ventilation and air conditioning. We often use this abbreviation to refer to your whole heating and cooling system, which includes:

·Comfort units, such as a furnace, heat pump, air conditioner or mini-split system

·Ductwork

·Indoor air quality solutions, like air filters, air filtration systems, germicidal UV lights, whole-house humidifiers and dehumidifiers, and ventilation

·Comfort controls, such as thermostats systems

While there are differing types of HVAC units, they all operate identically by:

·Relying on a fresh air source outside or inside your home or business.

·Running air through a filter to trap particles and allergens.

·Heating or cooling air.

·Sending air through a ducted system or immediately into a room, depending on the type of system you use.
