An HVAC unit circulates cool or hot air to regulate the temperature in your household or office space. HVAC installation involves the addition of heating and cooling fixtures to enhance comfort. Here are the parts of an HVAC system:
Heat Exchanger
The heat exchanger transfers heat within the HVAC unit. During high-temperature conditions, the heat exchanger absorbs heat from your home. In cold conditions, the exchanger releases heat into the household. It uses fluids and highly conductive walls to transfer the heat produced.
Thermostat
An HVAC unit has temperature sensors inside the thermostat. The sensors determine when the HVAC unit should heat or cool the home. During HVAC installation, technicians install batteries in the thermostat and connect the wiring. More complex HVAC systems in larger houses use multiple thermostats. Technicians place the thermostats in different zones of your home. Each thermostat communicates with the main unit to heat or cool specified zones.
Blower Motor
A blower motor provides force to pump warm or cool air to other rooms. Its sub-parts comprise the engine, case cover, and fan assembly. The motor produces a steady current of air, which circulates throughout the home via vents. Blower motors consist of two types: single-speed and variable-speed motors. Single-speed motors turn on when the thermostat detects a drop in temperature. Variable-speed motors run at different speeds to improve the airflow in the home.
Combustion Chamber
The combustion chamber produces heat in your HVAC unit. Fuel burns with oxygen in the chamber to produce heat. The heat from the reaction enters the heat exchanger for distribution into your home. Integrated circuit boards monitor the furnace and activate LEDs if problems occur.
Condenser Unit
Technicians place the condenser unit outside the home during HVAC installation. A condenser coil releases heat outside to cool your home. It compresses the refrigerant, converting it from a warm gas to a cold liquid. A fan blows air over the compressor to quickly cool the refrigerant and disperse heat. The liquid coolant moves to the evaporator coil through a copper or aluminum tube.
Ductwork
Technicians place the HVAC unit at a central location in your home. The ductwork transfers the air to designated locations within the household. Duct pipes are the core of HVAC ductwork, connecting to the air handler. The duct trunk is the main line, branching to duct pipes extending to rooms. HVAC manufacturers craft pipes and trunks from galvanized steel. Duct transitions link duct pipes and trunks. They include turning vanes, take-offs, and cleats. A plenum acts as an air reservoir in the ductwork. A supply plenum stores conditioned air. As fresh air enters a room, the displaced air goes to the return plenum.
Evaporator Coil
The evaporator coil transfers heat from indoor air to the refrigerant. This process vaporizes the coolant, transferring the heat to the outdoor unit. The evaporator coil can dehumidify your home by eliminating excess moisture in the air. Vapor in warm air condenses in the coil and gets drained away.
Refrigerant Lines
Refrigerant lines transport the refrigerant between the condenser and the evaporator coil. They are made from copper and can accommodate liquid or gas. A larger, insulated line carries cool gas, and a smaller, uninsulated line transports warm liquid.
Air Handler
The air handler circulates conditioned air to each part of your household. It attaches to the furnace, air conditioner, and plenums. Depending on the temperatures, the air handler pushes air to the furnace or AC unit.
