What Does HVAC Stand For?

When talking about your AC, you may hear people refer to it as a HVAC system. While the two are similar, they are slightly different terms. HVAC stands for heating, ventilation and air conditioning, while AC stands only for air conditioning. Your HVAC system is responsible for both heating and cooling as well as ventilating your home, while your AC is just responsible for cooling.

Living in Florida, we tend to only focus on the air conditioning. That doesn’t mean you should neglect the rest of you system though, as it is all important to your homes comfort. Here is just a little bit more to know about your system.


Floridians often ignore the importance of having a proper heating system. While we may not suffer the same kind of temperatures as those living up north, it’s still important to have for those chilly winter nights. There are two different types of systems that deliver hot air.

Direct Air: This moves the warm air directly to an area of the home. Direct systems generally use hydronic or electric systems to heat and move the air.

Forced Air: Using gas or electricity, forced air systems heat the air and send it through your home using fans. The warm air is pushed into a room through one vent, and then forces the cold air out through another.


A properly working ventilation system is vital to your homes comfort. When controlling temperature in your home, old air needs to be taken out so new air can come in. It is the job of the ventilation system to change this air for you. A good ventilation system will not only control temperature, but remove dust, bacteria, odors and carbon dioxide from the room.

To keep your vents filtering your air efficiently, but sure to change their filters at least once a month.

Air Conditioning

All Floridians know the importance of Air Conditioning. Not only does your AC cool your home, but it controls humidity as well. Your AC works by using a refrigeration cycle to chill the air. There are many different types and makes of air conditioners, but all require regular maintenance to run efficiently. To keep your AC running its best, be sure to schedule maintenance in the spring to prepare it for the long summer ahead.
