Clean out your gutters
There's no telling what kind of crud has collected in there since the last time you cleaned them out.
Do a deep fridge cleanout
Have some unidentified leftovers in a Tupperware way in the back or a long-ago expired jar of pickles in the door? The first step is to chuck it all - but make sure to schedule your cleanout to coincide with the trash pickup for the week. The last thing you want is a jar of mayo siting out in the bin for five consecutive 100-degree days.
While you're attacking the refrigerator, don't forget to address the coils. The coil is located either on the bottom behind the kickplate, or on the back of the refrigerator. To clean refrigerator coils, turn off the power to the fridge, then vacuum the coils using a homemade wand from a cardboard gift wrap tube or a vacuum cleaner brush attachment.
Change the batteries in your smoke detectors
It is recommended that smoke alarm batteries be changed out every six months. To make it easier to remember when it's time, do what the upper-organized do: Put yourself on a twice-a year-schedule in summer and winter (June 1 and December 1, for instance), and mark the dates in your phone so you don't forget.
Change out your filters
This is one of those areas where homebuyers don't tend to heed product manufacturers' guidelines. The general recommendation is every 30–60 days.
Deep clean your carpets
You should be doing this at least once a year to protect your carpets and limit allergens. Summer is the perfect time in most climates because the rainy season has passed, which means there's less likelihood of kids and pets tracking in mud.
Have your air conditioning unit serviced
If you're the type who only makes a call about your air conditioning when it's not working, consider this: Units that are serviced regularly tend to last longer and have a lower incidence of breaking down, which always seems to happen on the day when the heat index breaks a record.
As your HVAC system runs, it accumulates dust and dirt in key areas that affect its efficiency, like the condensing coils and air filters. Left unchecked, your A/C system can lose 5 percent of its operating efficiency each year because of this buildup, meaning it can't cool your house as capably as it could if it were clean.
If you haven't cleaned your showerhead in a year - or, ever - it's well past time. This involves one of our favorite home maintenance tips of all time, because it takes almost zero effort.
To clean, fill a plastic bag with white vinegar. Attach the bag to the showerhead. Wait one hour, then remove the bag and turn on the water to flush. Polish with a soft cloth.
Examine your clothes dryer vent
This is a critically important maintenance issue and should be done regularly. Not only will a clean vent make your dryer run more efficiently and dry your clothes faster, but it will also help keep your home and family safe.
