How to Hire the Best HVAC Installation Experts
Pre-installation, installation and post installation is the three step process which ensures the installation of HVAC. The objective of HVAC is to control the temperature of air along with control of moisture, filtration of air among others. The complete system of heating, ventilation and air conditioning is known as HVAC. A compressor, fan, evaporator coil and condenser is contained in an air conditioner for it to work. Heat absorption first occurs then transfer of heat to the refrigerant which is then pumped to the outdoor unit. The HVAC system contains vents, thermostat, furnace, heat exchanger, evaporator coil, refrigerant coils, ductwork and condensing unit as the main components.
The role of an evaporator coil is to cool air when the thermostat is set to lower temperatures. The purpose of an evaporator coil is the reverse role of a heat exchanger. Cool air is provided by an evaporator coil which is located to the mental enclosure on the furnace’s exterior, to the top or side and has a similar working to an automobile radiator. System of ducts that transport air warmed or cooled within the home is a duct work.
Ducts are made of lightweight aluminum but can be made from steel, fiberglass, fabric and flexible plastic. Thermostats are set on prominent easily accessible wall as they are the most visible feature in a HVAC system. Programming of the thermostat is done either in advance or manually in order to keep the temperature of the home at a desirable rate.
Warm air or cool air from the heat exchanger or the evaporator coil respectively is trigged by the thermostat. A substantial amount of space is required by the furnace since it’s the largest component of the HVAC system. Heating a supply of air is the main purpose of the furnace which is then distributed to the various rooms of the home. The process of heating is accomplished using the following sources of heat that is combustion, solar energy, electric resistance and heat pump.
The heat source which involves burning of propane, oil or coal is combustion. Inside the furnace the heat exchanger is located and its main role is to switch on the furnace when its activated by a thermostat to produce warmer temperatures. Drawing in of cool air then heating the air and finally circulation of the resulted heated air through the ductworks and vents is done by the heat exchanger.
A component of the HVAC system that is connected to the evaporator coil and is installed to outside the home is the condensing unit. The condensing unit is filled with a refrigerant gas in which it is cooled to a liquid by the heat exchanger then pumped to the evaporator coil to be evaporated to the gas once more.
