Bob Vila’s 35 Must-Do Projects for Fall

For as long as there have been air conditioning covers, people have debated whether they're a good idea. Advocates love covers for the way they keep ice and debris out of the machinery, while detractors fear that covers can create ideal habitats for rodents and other pests that can nest within the wiring. Whatever the case, homeowners who live in colder regions should consider at least covering the top of their outside AC condenser unit with a tarp or sheet of plywood, even if they leave the rest of the unit exposed. Window units, on the other hand, should be removed, cleaned, and stored in a safe place until they're needed again in the summer.
