Different Types Of HVAC Systems

There are a few different types of HVAC systems that are available, each using a slightly different method to heat and cool as well as using different energy sources. Although they all offer the basic elements of heating, ventilation and air-conditioning, depending on the energy sources available and how the unit is used, one may suit a home or business better than another.

–        HVAC system using furnace and condensing. This system uses a transfer of air from outdoors to replace indoor air, which is pushed out of the building. The air is pushed through by the motor and blower, then either warmed by heat exchangers from the furnace, or cooled through the evaporation coils. These are usually split systems, with heat and air conditioning separated.

–        HVAC zoning. Very common in large commercial buildings, HVAC zoning allows the premise to be divided into different zones, so each area can be controlled differently in regards to temperature. These systems use dampers that control the air flow, and will have different thermostats to gauge temperature levels in each zone. Although they’re more popular on the commercial level, these systems can also be in residential homes as well.

–        HVAC system heat-hybrid. Similar to split systems that use furnace and condensing, these use a heat pump instead of an air conditioning unit. This can be a more energy efficient system, using electricity for the heat pump which helps in both heating and cooling.

–        Ductless Mini-Split systems. Theese packaged systems are smaller and use less space than a traditional split system, and are often an excellent alternative for applications where installing ductwork is impractical or undesireable. The systems will generally contain a heat pump, thermostat, fan coil and an evaporator coil, all in one package.
