What is HVAC?
HVAC hides in your walls. But unlike grandma's collection of porcelain dolls, HVAC helps you breathe easy.

H-V-A-C... Let’s break this down.
These systems are made up of a combination of magic metal boxes that make your air hotter or colder. The whole reason they exist is to keep you comfy inside, no matter how hot or cold it is outside.
H is for Heating
The furnace is the most common source of heat. It literally uses fire to make warm air that's blown around your home.
V is for Ventilation.
Speaking of blowing, the thing that blows the air through your ductwork is called the blower. Kind of like your lungs, it's essential for circulating fresh and comfortable air.
AC is for Aaah Chilly.
Nah, just kidding. Glad you're still paying attention though. AC stands for Air Conditioning. The home's cold air is supplied by the air conditioner.
The thermostat does.
The brains of this operation is the little computer on your wall, a.k.a. the thermostat. It tells those metal boxes how hot or cold you want things.
