Attic renovation & ventilation issues
Hi...hope someone can help us! My daughter & husband had about 3/4's of their attic turned into living space....also, added a shed dormer for height for 2 bedrooms & 1/2 bath installed. They had a contractor do it, but he passed away right after the completion. So, now they have no one to answer some concerns about some ventilation issues. They had a separate Carrier a/c unit installed to handle this new space, but their electric bill was huge. So, they called up the a/c guy & he came out & told them that there isn't no insulation where the a/c unit was installed & also, the area where the storage space still remains. The a/c guy said that the a/c unit was just drawing in the hot air...outside temps & insulation should be put in that area. We live in Louisiana...so, our summer temps run in the 90's &100's. So, they went to Lowe's & got instructions on how to put in the insulation & got that done....but, now they've noticed that they have no roof line "ridge" vent, circulating turbines...only...soffit venting. Before this attic renovation they had an electrical fan vent on their roof...which the contractor removed. But, anyway...should they install more vents on the roof or gable ends? Any suggestions? We've been trying to get other contractors to come out & suggest a solution...but, here in Louisiana...contractors are hard to find...most are still down in New Orleans...engaged in the rebuilding there. Any suggestions would be appreciated. Thanks so much!!!
