Cover up Air Ducts
.Construction dust sucked into return air ducts can plug your furnace filter. Even worse, small particles can pass through the filter and coat every room in the house with a blanket of fine dust when the blower turns on. Air supply ducts can be a problem too—dust that settles inside will come blasting out when your heating/cooling system starts up. You can close the damper on a supply register, but it won't seal out dust as effectively as plastic and tape. Note: Turn off the heating/cooling system while the ducts are covered. Operating the system with restricted airflow can damage it.

Rent a Walk-Behind Floor Scraper
Some old vinyl sheet or tile floors are super easy to pull up. Others are so thoroughly glued down that you're lucky to remove quarter-size chunks with every whack of your handheld floor scraper. If a shovel and hand scraper are just not getting the job done, rent a walk-behind scraper. For about $50 to $60 a day, you can save yourself a bunch of time and prevent a whole lot of wear and tear on your back and wrists. Many floor scrapers have an attachment for busting up ceramic tiles as well.
