Is there a way to measure the efficiency of a new Lennox G61V?
My dilemna is as follow: The house wil be built over Fall & Winter. I paid a premium $$$$ to have furnace upgraded to Lennox G61V (from the G43 that comes standard with the house).
I don't have the owner's manual for the G61V, but I have it for the 90UGF. And in it, it says, "NOTE - 90UGF series must not be used as a construction heater during any phase of construction. Very low return air temperatures, harmful vapors and misplacement of filters will damage the unit and lower its efficiency."
I know for a fact that the furnace will be used during construction of the house and it is logical to assume that this "NOTE" also applies to the G61V.
What I would like to do is get a Lennox guy on the day I take possesion of the house to see how much damage the builder has done to the furnace.
So is there a "scientific" way to measure how much damages was done to the furnace by the builder during construction?
Thanks for your time.
