I can already feel the difference in the temperature and strength of the air coming out of our vents. Plus, rooms that always seemed chilly are now toasty warm. The photos proved it: we had a half inch of fuzz in all our vents. It was a tricky job but Rudy did everything he could to get to some of our tight spaces with difficult access. He also was meticulous in keeping snow, dirt, and scrape marks OFF the wood floors and furniture. This seems to be a vital and often overlooked service. I think we will be better heated with cleaner air from now on.
