The phrase "spring cleaning" doesn't just have to mean cleaning the inside of your house. There are lots of other home maintenance-type things that would benefit from your attention once spring has actually sprung. Murphy's Law says that if your air conditioner breaks down, it's probably going to happen right in the hottest part of the summer. So before it gets hot, get your system checked out to make sure that it'll actually work well for you when you turn it on.
If the winter was particularly rough, your roof probably needs an inspection for loose shingles, your siding might be loose or rotting and your gutters could be full of gunk. Take care of it all before summer does its own damage. Lots of people talk about weatherproofing to keep in the warmth during winter, but if you didn't do that, consider things like caulking around your windows and sealing any other leaks to keep in the cool air once you turn on that AC. You'll soon want to spend time on your deck or patio, so inspect that for wear and tear and get it into shape. If you do all of these things yourself, mild spring temperatures might even make them slightly enjoyable.
Do you have a completely perfect, sparkling clean and organized house inside and out by the time spring rolls around? Not me; there's always something left to do. But it's good to have goals, and maybe this year you can get a little further with the help of these spring cleaning tips.
