If you are the type of inspector who does not remove the screwed on cover plates on furnaces or air handlers, then turn on the furnace and check for the temperature differential between supply and return air. It should be greater than 35 degrees.
If you remove the cover panels, you should check the amperage draw on each of the strip heaters . They should draw between 15 and 22 amps when on. There may be a sequencer in the system which turns on the elements one or two at a time. If they don't come on, they may be nonfunctional, or there may be an outdoor thermostat. If there is an outdoor thermostat it would have to be returned to it's initial set point, which is usually better left to an HVAC tech. It is also important that the blower comes on with or just prior to the first element.
Look for the usual items such as blown fuses, blower operation, burned or corroded wires, filter, etc. If you provide a BTU output to your buyer, each kilowatt is equal to 3412 BTU. Most, but not all strip heaters are 5kw each. (3 strips = 15 kw, etc) Often, the KW is listed on the outside of the furnace cabinet.
These are very common in my area. We have very few gas furnaces.
Hope that helps. ![icon_biggrin.gif](upload://iKNGSw3qcRIEmXySa8gItY6Gczg.gif)
