Home HVAC systems have seven key elements that make up the units.
Main Unit: Traditional systems include heat pumps, central ACs, furnaces or boilers as their main cooling and heating units.
Thermostat: Considered the brain of an HVAC system, thermostats control when your unit turns on and off based on their settings.
Air Handler: Air handlers hold the components required to circulate air throughout the home.
Evaporator Coil: Evaporator coils facilitate an HVAC’s cooling and heating and are a crucial component of any home unit.
Condenser Coil: This coil is attached to the outdoor condenser unit and works with the indoor evaporator coil to regulate indoor temperatures.
Heat Exchanger: Gas furnaces rely on heat exchangers to generate warmth inside the home and require regular HVAC maintenance to ensure there are no cracks — which can lead to harmful gas emissions.
HVAC Ducts: HVAC ductwork is responsible for distributing conditioned air throughout a home or business and requires regular inspections to ensure no leaks are present.
