What Does HVAC Mean?

The term HVAC stands for heating, ventilation and air conditioning. In most homes you will have an indoor unit called an air handler, an outdoor unit called a condenser, and a duct system which runs through your attic space or a crawl space to deliver the air throughout each room of your home. While your system’s heating component produces warm air, the cooling component actually removes heat from the air causing it to feel cool.

As Floridians, we generally place the most value in the AC part of HVAC, but each component of this acronym is equally important in providing a home environment that is comfortable and healthy. Learn more about what your HVAC system does for you.

Heating

You may not get regular use out of your heating system, but even Florida’s mild winters call for a warm, toasty home from time to time. The two most common types of heating systems in Florida are heat pumps and straight cool systems with electric heat. Heat pumps provide heat by extracting the heat from the outdoor air and transferring it through the outdoor and indoor portion of the system, into your home through the duct system. Straight cool systems with electric heat use an air handler with heat strips that heat up like a toaster and circulate the heat through your home. Homes in cooler climates may use a furnace to produce heat, which commonly run on gas or oil.

Ventilation

While your duct system distributes the warm or cool air throughout your home, it does not provide for ventilation. The ventilation component consists of removing objectionable odors and contaminants from spaces such as bathrooms and kitchens.  This is done through a separate exhaust fan. Ventilation can also consist of bringing in fresh outdoor air and adding it to your AC system, thereby spreading it through your duct system. Adding outdoor air to your system will help to combat stale and contaminated air.

Air Conditioning

The most common type of cooling system is a split system, which contains both outdoor and indoor components. Outside you’ll find a condenser and a compressor, and inside you’ll find an evaporator coil and blower motor. The compressor pumps refrigerant through your system, which converts from a gas to a liquid, then back again. This allows your AC to transfer heat from inside your home to the outdoor air.
