Heating and cooling are important factors that affect the overall comfort of your home. Studies have shown that nearly half of a home’s energy usage is devoted to heating and cooling, making your choice of HVAC system an important one. There are many different options when it comes to heating and cooling your Nashville home; the best choice for you will depend upon your current HVAC system, as well as your personal preferences and long-term heating and cooling needs.
Central Heating and Air Conditioning
Central heating and air conditioning are very common in modern homes. These HVAC systems rely on a set of ducts to transport heated or cooled air from your HVAC appliances into the living areas of your home. Thus, central air conditioners and furnaces share an air handling unit, which blows the treated air up into the ducts. Central air conditioners have two components: an indoor evaporator and an outdoor condenser. The refrigerant solution is cycled between these two units, removing heat and moisture from your indoor air to be shunted outside and keeping your home cool and comfortable. Most furnaces heat air via combustion, using fuel sources such as oil, natural gas, and propane. The efficiency of your furnace will depend upon both the type of fuel it uses and the efficiency of the model you have installed.
Ductless Mini-Split Air Conditioning
If you don’t have central air conditioning but prefer not to use window air conditioners to mini-splitroom at a time, ductless min-split air conditioning is a great alternative. Mini-split systems require only a single hole in your home’s exterior, typically one to three inches in diameter, to accommodate cabling and refrigerant lines. The mini-split system is comprised of an outdoor compressor and one or more indoor air handling units. Typically, a single condenser can be used to provide cool air for several indoor units, which can be placed in each room you wish to cool. No existing ductwork is needed, and air handlers are handled separately via remote or control panel.
Heat pumps conduct temperature exchange with either the air or the ground outside your home, providing both cooling and heating as needed. These HVAC systems can be used alone or in conjunction with a traditional furnace, as heat pumps may not be sufficient to provide heating in extremely cold temperatures. However, heat pumps are particularly beneficial in areas with mild climates, such as Nashville. Because a single heat pump can handle most or all of your home’s HVAC needs, you can save money and reduce your home’s energy consumption, thanks to the high efficiency of heat pumps when in both heating and cooling mode. Heat pumps can be used in a traditional central air configuration (i.e., in a home with ducts), or as a ductless mini-split system.
Boilers use radiant heating to deliver heat to your home, requiring fuel such as wood or biomass, natural gas, propane, or oil. Inside the boiler, water is heated and turned into steam, which travels through pipes to radiators or under-floor heating to keep your home comfortable. Boilers may be either closed or open systems—closed systems reuse the same water over and over, while open systems must be refilled, either manually or automatically, to continue producing steam.
