How familiar are you with your heating and air conditioning unit in Portland? Knowing the basics of your HVAC system can be important for its maintenance and identifying a need for repairs. Read on to learn about HVAC terms that you should know as a homeowner.
Responsible for the cooling aspect of an air conditioner’s function, the evaporator coils of the unit contain refrigerant that absorbs heat from the air.
For a building or room that lacks air ducts, mini split systems offer an air conditioning solution. These appliances are quiet, versatile, and are ductless air conditioners that have small, external and internal units.
Energy Recovery Ventilator
A common component of air conditioning units, an energy recovery ventilator (ERV) can improve the indoor air quality provided by the HVAC system and allow the unit to cool a building more efficiently.
Air Handling Unit
Air handlers or air handling units (AHUs) are devices that circulate and condition air. The AHU component of an HVAC system is typically a large, metal box that houses heating and cooling elements, a blower, dampers, sound attenuators, and filter racks.
Heat pumps work much like standard air conditioners, but they can be far more energy efficient. A heat pump absorbs heat from the air inside your home and transfers it outside. During cooler weather, these units can perform the opposite function by taking heat from the ground or outside air and using it to heat your home.
Able to offer significant savings when compared with electric-powered units, oil furnaces offer consistent and efficient heating for the winter months.
Through combustion of natural gas, a furnace can help keep your home warm during the winter by producing heat that warms a heat exchanger. Air is blown over the heat exchanger to warm it and then circulated throughout the home. During warmer weather, the blower continues to run as it forces air over the condenser coils to cool it and then push it into the home.
