Heating and cooling are 2 of the most important concepts of home ownership. In fact, heating and cooling systems are major factors for those looking to purchase homes, and are a critical part of living comfortably in a home.
You may frequently hear the term "HVAC," which is used to describe home heating and cooling systems. The acronym stands for Heating, Ventilation and Air Conditioning–which are the 3 primary functions of a home system. They control air temperature and humidity, and maintain the quality of the air in the home.
Heating and cooling systems may be classified as central or local. Central heating and cooling is the most standard method, and is defined by a system that produces warm or cool air in one central area and then distributes it throughout the home. There are many types of systems that work as central systems, from traditional split systems to packaged product systems.
Products typically used in central heating and cooling systems include:
Local heating and cooling, on the other hand, produces warm or cool air at the location where it is needed and serves small spaces. Room Air Conditioners and Ductless Split Systems are examples of local heating and cooling.
Heating systems keep your home warm and comfortable. If you live in a particularly cold climate, the function of your heating system is a high priority.
Most central heating and cooling systems are classified as forced air systems, because they send air through ductwork for distribution. The ductwork can contain products that filter or clean the air.
Radiant systems create heat and deliver it using components such as radiators that distribute the heat into the home. Boilers are a traditional radiant heat source.
Typical heating products include:
Whole-home air conditioning systems are central systems that rely on ducts to deliver cooled air throughout the home. An air-conditioning system provides cooling, ventilation, humidity control and even heating (if using a Heat Pump) for a home. Air conditioning units cool refrigerants like Puron Refrigerant and Freon and deliver them to evaporator coils, which dissipate the refrigerant and blow cool air into ducts for delivery throughout the home.
Products such as room air conditioners are local cooling options for smaller areas within homes. Instead of delivering cooled refrigerant to a coil and then to ductwork, a room air conditioner contains all the components in a single unit and blows air directly into a room.
Air-conditioned homes often have sealed windows, because open windows would disrupt the attempts of the control system to maintain constant temperature.
Typical air conditioning products include:
As the name implies, a ductless split system does not rely upon air ducts to route treated air through your home or office. Instead, these specialty products are added for a specific room, such as a home theatre, an exercise room, a garage, or other room where adding ducts is impractical. These comfort systems can supply heating, cooling, or both, and are a split-system in that the condensing unit sits outside your home while the indoor unit sits unbotrusively on the wall to control and direct the airflow. These Carrier systems are full-featured and couldn't be any easier to operate.
Typical Ductless Systems:
The term "thermostat" commonly refers to any unit that controls the operation of a heating and cooling system. Thermostats are used to turn on heating or cooling systems to bring the home to a set temperature. In addition to basic temperature control, programmable thermostats can be used to manage the timing of the system's functions, which can control overall energy use and costs.
