In every HVAC system, there are essential units namely heating, ventilation, and air conditioning units. Also, in modern systems, there is an air filter and a cleaning component. In most residential buildings, a furnace or a boiler is used to heat.
They are made up of an indoor unit and an outdoor unit, which allows them to be installed almost anywhere—on the wall or ceiling in your attic, in a closet or utility room, or even on the outside of your home (if you can find a place that’s not too visible).
Although many air filters are disposable and cannot be cleaned, thanks to new technologies, washable air filters are also available in the market. If the filter of your HVAC-R is disposable, it is better to replace it with a washable filter.
The blower helps distribute cold or warm air throughout the house until it matches the temperature set by the thermostat.
