I think perhaps I will start offering a new side to my inspections by offering the home owners a post inspection after installation by Hvac contractors. After two of my inspections this week can see a great need in this area for this as the city inspectors are not doing their job if a permit was even obtained which it probally was not.
I just came off an inspection this afternoon that the contractor should have his license pulled.
The house old two story renovated for a flip. The thermostat within 5 feet of the kitchen stove two returns one above the stat and one below, both wall mounted close enough to the kitchen stove to be used for a stove exhaust fan:) . Up flow furnace resting on a wood return box that had approximately 4 inches of the floor removed inside the return chamber drawing un-conditioned air from the crawl space. The Goodman furnace was installed in 06 and has the condensate overflow cup mounted on the exterior side of the furnace. When this cup fills with water it overflows into an open ended drain line that was hard piped into the kitchen sink drain line under the home no P-trap. The sewer gas travels back up the line to the open end of the drain and into the home.
I encounter bad installs like this very frequently and have been considering adding a post inspection for the consumer before they pay the contractor good money for bad work. What do you think would it work or would I just piss off all of the contractors that do good work???
