"Overall very satisfied from beginning to end. I consulted with two other contractors before deciding on Weather Crafters. the others paid little attention to my crawl space where the air return duct work is. They (other companies) said the original 21 year old duct work was satisfactory for a new system . Weather Crafters said it should be replaced as it was falling apart and wouldn't be adequate for the new system. This impressed me along with how they sealed the foundation holes from the older system. Will and have recommended Weather Crafters to friends."
