What is HVAC?
HVAC stands for heating, ventilation, and air conditioning. HVAC systems help to control the indoor temperature for residential and commercial buildings.
Selecting an HVAC system is much more complicated than heading to your local mall to buy a new pair of jeans. In the world of HVAC, there is no such thing as ‘One Size Fits All!’
HVAC systems can actually be quite complex. Finding the right type of system for your home or business is not easy.
When getting ready to purchase a new HVAC system, it’s extremely important to make sure the system not only heats and cools effectively, but that it is also energy efficient.
Choosing a system that uses a lot of energy will quickly cause a dent in your bank account!
HVAC systems come in many types and applications. The two types of HVAC systems are central or local.
Central HVAC Systems
In a central air conditioning and heating system, the necessary heating, cooling, and ventilation is provided from a central location in the building, such as from a boiler room. Central air works by pushing heated water or steam through piping or ductwork throughout the building to achieve heating and cooling.
Central air conditioning units use a compressor and a condenser unit that uses a refrigerant or coolant such as Freon. The refrigerant gets circulated through copper tubing, absorbs the heat, and then turns to vapor. Once the refrigerant is in vapor form, it travels to the compressor, and to the door where the heat is forced out.
Once the air is cool, it travels through the ductwork to cool the building.
Once the cool air has made its way circulating through the building, the refrigerant has to pass through a device where it is converted to a low temperature liquid and returned to the indoor coil.
Local HVAV Systems
Local HVAC systems provide heating and cooling to individual areas or rooms. Unlike central HVAC systems, local systems do not circulate throughout entire structures. Local HVAC systems can be anything from wood or pellet stoves, window air conditioners, and space heaters. Electric baseboards can also be considered a local HVAC system, if the unit is installed into a single area.
There are a lot of factors that determine which HVAC system is right for you and your needs. You should always consult an HVAC professional before making any purchases.
A qualified and certified HVAC contractor will determine the type of unit that is best for you, and will install the unit in the proper place so that it will meet your cooling and heating requirements.
