Here is the thing about seasonal home maintenance — it does not care that you are busy. It does not care that you just got through spring cleaning, that you have three kids with end-of-year activities happening simultaneously, or that you would really like to just sit outside with a cold drink and enjoy the fact that it is finally warm. Your house has needs, summer has arrived, and a few hours now will save you a very expensive and inconvenient conversation with a contractor later.

The good news is that none of this is complicated. It is mostly just a matter of knowing what to look at and actually looking at it before something fails quietly in the background for three months while you are busy living your life.

Here is what needs your attention right now.

Check Your Air Conditioning Before You Actually Need It

If you have not already run your AC this season, do it today — not on the first genuinely miserable day in July when it is 97 degrees and you have company coming. Turn it on now, let it run for a while, and make sure cold air is actually coming out of the vents. While it is running, walk around and check that every vent in the house has airflow. If one room is noticeably warmer than the others or barely getting any air, something is off and you have time to deal with it before it becomes a crisis.

Also change your air filter if you have not done it recently. A clogged filter makes your system work harder, runs up your electric bill, and shortens the life of your unit. Filters are a few dollars. A new AC unit is several thousand. The math is not complicated.

While you are at it, go outside and look at your AC unit. Clear away any grass, weeds, or debris that have grown up around it over the spring. It needs at least two feet of clearance on all sides to breathe properly. Gently rinse the fins with a garden hose if they look dirty — just do not use a pressure washer on them because the fins bend easily and then you have a different problem.

Inspect Your Ceiling Fans

Ceiling fans have a direction switch that most people set in October and never think about again. In winter, you want the blades running clockwise on low to push warm air that has risen to the ceiling back down into the room. In summer, you want them running counterclockwise to push air straight down and create a wind-chill effect that makes the room feel cooler.

Flip the switch — usually a small toggle on the motor housing — to counterclockwise if you have not already. Then turn it on and stand under it. You should feel a breeze. If you do not feel anything, it is still running the wrong direction.

While you are up there on the step stool anyway, wipe the blades down. Ceiling fan blades accumulate a truly impressive amount of dust over a winter, and when you turn the fan on for the first time, that dust goes directly into the air you are breathing. A damp cloth or a pillowcase pulled over each blade and then pulled back off takes care of it in about two minutes.

Walk Around the Outside of Your House

Winter and spring are hard on the exterior of your home, and now that everything has dried out, it is worth a slow walk around the perimeter to see what survived and what did not.

Look at your caulking around windows and doors. Caulk shrinks, cracks, and pulls away over time, and gaps in caulking let in moisture, insects, and conditioned air you are paying to cool. If you see cracks or areas where the caulk has pulled away from the surface, a tube of exterior caulk is inexpensive and the fix takes about fifteen minutes.

Check your window screens. Summer is the season you actually want to open windows, and there is nothing more annoying than discovering a torn screen when you are trying to get a breeze through the house and also not invite every mosquito in the county to come inside. Now is the time to find the damage and either patch it or replace the screen before you need it.

Look at your deck or patio if you have one. Check for boards that have warped, cracked, or feel soft underfoot, and look at the ledger board — the part where the deck attaches to your house — for any signs of rot or separation. Decks take a beating in winter and problems get worse fast once summer foot traffic starts.

Clean Your Gutters (Yes, Again)

You may have cleaned them in the fall. Spring dumped a whole new round of debris in them anyway. Gutters full of spring buildup cannot drain properly during summer thunderstorms, and when water has nowhere to go it finds creative solutions — like behind your fascia boards, down your foundation, or into your basement. None of those are solutions you want.

Clean them out, run a hose through them to make sure water flows freely toward the downspout, and check that your downspouts are directing water away from your foundation. They should be depositing water at least three to four feet away from your house. If they are dumping it right at the base of your foundation, add a downspout extender. They cost about ten dollars and they matter more than they look like they do.

Check Your Hoses and Outdoor Faucets

Winter can crack outdoor faucets and hose bibs even when they are properly winterized. Turn each one on and check for drips at the connection point, which can indicate a cracked washer or a fitting that shifted over the winter. Also check your garden hoses for cracks along the length and at the connectors. A hose with a crack near the spigot end will spray water everywhere except where you are pointing it, which is both wasteful and annoying.

Test Your Smoke and Carbon Monoxide Detectors

This one has nothing to do with summer specifically and everything to do with the fact that you are home more in summer, the kids are home more in summer, and you have been meaning to do this for a while. Push the test button on each one. If it does not beep, replace the battery. If it is more than ten years old, replace the whole unit.

It takes five minutes to test every detector in your house. Do it this week while you are thinking about it.

The Short Version

You do not have to spend a whole weekend on this. A couple of focused hours knocking through the list — AC check, fan direction, exterior walk-around, gutters, outdoor faucets, detectors — and you will head into summer knowing your house is in reasonable shape. That is a genuinely good feeling.

The alternative is ignoring it and finding out in August, the hard way, what you missed in June. And August in Missouri is not the month you want to be dealing with surprises.
