I had contacted a licensed well known local HVAC contractor to install several supply registers in the drop ceiling of my basement that already had 2 in the drop ceiling when I bought the house. He did the work while I was at work one day and did not inform me that he had decided to install these in the walls near the ceiling. He also installed a cold air return in the furnace that is located in the laundry room with the hot water heater.
My question is…according to several people I’ve talked with, this is illegal? How so? Also, I had my local gas company test for carbon monoxide and the tech only tested around the furnace area after several minutes of having the heat turned on. Luckily, he said there was no reading of carbon monoxide.
This contractor has sued me for the cost of the work he has done and I am countersuing for the damages he has done to my home. I’m hoping I can find proof that it is illegal to have the return in the same room as the furnace. Any help is much appreciated.
