Can I help you???

Well I tell ya, I HATE slotted screws!!! Likely one of THEE WORST episodes was back when I worked in HVAC. I mostly did service and AC/ heat pump installs, and control wiring, hung some gas pipe, I NEVER hung ductwork.

But one job I had no urgent service work, and we were in a hurry to get this going for the folks. They had to have temporary electric heat otherwise. This was an old "octopus" gravity convection hot air furnace, and took up most the basement. The upgrade started out simply enough........disassemble the damn thing and get it out of there. ALL THE DUCT and ALL THE FURNACE sheet metal was SLOTTED HEAD screws. And of course the entire jacket around the combustion chamber had to come apart and off, because it was so large and heavy. Trying to remove dozens of slotted screws, power driver or not IS NO FUN
