Q: Where are all your filters, and when was the last time they were replaced?

Lots of appliances in your home have filters. In fact, any device that conducts air or water should have some sort of filter in place to remove impurities and particulates. Changing these filters routinely can save you money, and keep you safe, which is why it’s helpful to know when they’re due to be replaced. Furnace filters should be replaced every two to three months; HVAC, ice maker, and water dispenser filters must change at least once a year. But that varies based on the manufacturer, so be sure to check your maintenance manual and not let it slide.

Q: Does your home have a sump pump, and do you know how to maintain it?

A sump pump is a pump (duh) installed in certain basements and crawl spaces to keep these areas of your home dry, which it does by collecting water that tries to seep in and moving it far, far away (or at least as far as the drainage ditch in your yard). They’re especially common in regions where basement flooding is an issue. Without a sump pump, the invading water can result in thousands of dollars in damage.

The good news, though, is that sump pumps are relatively easy to maintain. Check both lines, in and out, to make sure they’re not clogged with debris, and make sure the float component (this is the little bob that floats upward when water begins to fill the sump pit, activating the pump) can move smoothly.
