Alan, If you have central air-condx/heating with variable speed compressor and / or fans(s), shut it down and check for the spurs. What you are describing is the same I see at my QTh when my unit is cooling/heating. I see spurs only wihen the compressor and/or fans are running. My unit is a “dual fuel” unit, used as a heatpump above 43F, swithching to a gas fired furnace below 43F. It has no electric powered “heat strips.” For summer cooling it is configured as a “normal” AC unit.
