How to Hire the Best HVAC Installation Experts
HVAC installation involves a three step process which is the pre-installation, installation and post installation which ensures the specifications and expectations are met. Controlling the temperature of air along with controlling of moisture, filtration of air among others is the main objective of HVAC. The complete system of heating, ventilation and air conditioning is known as HVAC. The working of an air conditioner is known to first contain a compressor, condenser, evaporator coil and a fan. Absorption of heat from the air is transferred to the refrigerant which is then pumped to the outdoor segment. The main components of a HVAC system include; vents, thermostat, furnace, heat exchanger, evaporator coil, refrigerant coils, ductwork and condensing unit.
When the thermostat is set to lower temperatures then the evaporator coil is used to cool air. The purpose of an evaporator coil is the reverse role of a heat exchanger. The evaporator coil is located to the mental enclosure on the furnace’s exterior, to the top or side and also is known to work as an automobile radiator resulting to producing cool air. System of ducts that transport air warmed or cooled within the home is a duct work.
The most common material used in making of ducts is lightweight aluminum but can also be found in the following forms 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. So as to keep the temperature of the home at a desirable rate then the thermostat is set manually or programmed in advance.
The thermostat is able to trigger the heat exchanger or the evaporator coil to circulate either warm air or cool air. The size of the furnace is quite large and thus requires a substantial amount of space. The purpose of the furnace is to heat a supply of air which is distributed to the various rooms of the home. Accomplishment of the heating process is done through the use of the following heat sources which are combustion, solar energy, electric resistance and heat pump.
Burning of natural gas, propane, oil or coal is the what is involved in the process of combustion. The location of the heat exchanger is inside the furnace which switches on the furnace when its activated by a thermostat to produce warmer temperatures. The heat exchanger therefore draws in cool air, heats the air and circulates the resulted heated air through the ductworks and vents.
Installation of the condensing unit is outside the home and is connected to the evaporator coil. 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.
