HVAC refers to the different systems used to move air between indoor and outdoor areas, along with heating and cooling residential and commercial buildings. By getting biannual maintenance for your HVAC systems, you can save money on repair or replacement service. HVAC maintenance can also reduce your bills, save energy, provide you with better indoor air quality, make your HVAC system run smoothly, and reduce repairs. Typically, an HVAC technician will be responsible for the maintenance of your HVAC, although homeowners can do their own maintenance.
So what exactly is the difference between HVAC and air conditioning? Well, air conditioning is actually the last part of what HVAC stands for, but they are often used interchangeably in reference to any type of heating or cooling device in a home.
