How far away should a heat pump condenser (outdoor unit) be from the house?
Friday, January 3, 2020
Manufacturer’s installation manuals specify a minimum of 12 inches clearance around a condenser, but 24 inches from a solid wall or fence is necessary. The unit needs space around it for the circulation of air that is being drawn through the condenser coils and out the top.
Also, although a condenser (outside unit) is part of a home's HVAC system, it is an electric appliance that requires service occasionally. So the National Electrical Code requirement (NEC 110.26[A]) for equipment “likely to require examination, adjustment, servicing or maintenance while energized” applies, which specifies a working space 36” deep and 30” wide in front of the air handler. This only applies at the service side(s) of the condenser.
