I had a new HVAC system and new roof with a ridge vent installed several years ago. I am now seeing visible indentions (inside my home) of beams on the ceiling sheetrock and tape and float peeling both inside of my home and in my attached garage where ceiling and wall join. I also have noticed 2 cracks that run vertical from floor to ceiling on the adjoining wall from attached garage and living room. These cracks are straight down the sheetrock in the middle of the room. I am also hearing popping and cracking noises that never happened before the new roof and AC were installed. HELP...I don't know if I should contact an HVAC, structural engineer or foundation company. I would appreciate input and recommendation as to what type of company to contact for a resolution.
