What is HVAC?

HVAC is an acronym that stands for heating, ventilation and air-conditioning systems. This includes products like furnaces, air handlers, packaged units, heat pumps, air conditioners and whole-home ventilators. The ductwork connected to these pieces of equipment is another component of HVAC, as well as thermostats and other home comfort controls.

Components of HVAC

An HVAC system, also called split system HVAC or a home comfort system, has four major parts:

  1. Indoor unit, such as a furnace or air handler
  2. Outdoor unit, either an air conditioner or a heat pump
  3. Thermostat
  4. Indoor air quality component, like a filtration system or humidity control product

All these components work together to optimize your home’s comfort, improve your home’s indoor air quality, and maximize your home’s energy efficiency. Learn more about how HVAC systems work.

HVAC can also include indoor air quality (IAQ) products with capabilities that go beyond ventilation. Air cleaners or air purifiers, humidifiers, dehumidifiers and filtration systems are all products that can help remove allergy-aggravating contaminants from a home’s air.

What HVAC system is best for me?

Picking the right HVAC system for your home depends on many factors such as:

• Size and age of your home
• Your home’s design and layout

• Condition of ductwork
