What is the required clearance for access and working space in front of a furnace or air handler?
Saturday, June 16, 2018
Although a furnace or air handler is part of a home HVAC system, it is an electric appliance. 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 appliance.
The requirement for working space in front of a gas or oil-fired furnace would also be the same, because of the electric circuits in the appliance that are likely to require service.
