What Does HVAC Mean?

March 17, 2020

HVAC stands for heating, ventilation, and air conditioning. Most homes and businesses have an HVAC system. There are a number of different HVAC components in use today, including furnaces, air conditioners, heat pumps, and ductless units. Here’s an overview of these systems.

How HVAC Works

Your home might have separate components for heating and cooling, such as a furnace and an air conditioner. Some houses have heat pumps that can both heat and cool the home. It’s usually the case that even with separate components, there is a single blower that circulates air around your residence. Heated or cooled air enters your living space through registers and enters a return register that leads back to your furnace.


An HVAC system does more than just heat and cool your home. A part of HVAC that is often overlooked is ventilation. These systems improve your home’s or company’s air quality since they bring in fresh air and vent stagnant air. Your property can even ventilate naturally by losing air through doors, windows, vents, and other openings.

McKinney Heating & Air Conditioning is a heating and cooling company that makes sure homes and businesses are properly ventilated. We serve the greater Martinsville and Fieldale areas.

Mechanical Ventilation

HVAC companies often install mechanical ventilation systems. This is especially important nowadays, as improvements in construction have led to less natural ventilation. Houses and businesses today are tightly sealed, which keeps indoor and outdoor air separate.

In a mechanical ventilation system, air is brought into a building and sent through a filter. The filter removes dust, dirt, and other particles. The air is either heated or cooled depending on the thermostat settings.
