Speaking of dryer pet peeves.... in 2014 I moved a few blocks away. When I sold my house, to get the C of O, I needed to update my gas pipe for my dryer, copper was no good anymore. Ok. My HVAC friend who lives in the city didn't get it but went to the city, watched a video to get educated so he could serve other customers in the area.
New house. Order washer and dryer. They won't hook up the dryer because it's copper fittings and pipe. Yeah, I had to do the same thing to the house I bought that I did to the house I sold. The seller got a C of O.
