There’s a specific window in Wylie between the last cool mornings of April and the first genuinely brutal week of June where the whole town quietly gets its houses ready for the six months that follow. It’s shorter than people think, and most of it is invisible until it’s skipped — nobody notices a sprinkler head that was never checked until the lawn shows a dry patch in July, or an AC filter that was never changed until the electric bill jumps in August. Here’s what actually belongs on that list, and roughly when.
Turn the sprinkler system on before you need it, not during a heat wave
Once NTMWD’s April-through-October watering rules kick in — no more than two days a week, restricted to your assigned trash-pickup days, and nothing between 10 a.m. and 6 p.m. — every household is on the clock to use its allotted watering time well. That only works if the irrigation system is actually functioning. Run a full test cycle on every zone before the heat sets in: look for heads that are clogged, tilted, or spraying the driveway instead of the lawn, and fix them now while a plumber or irrigation tech isn’t booked out by everyone else discovering the same problem in June.
Get ahead of storm season rather than reacting to it
North Texas’s spring severe weather season tends to front-load into these exact weeks, with the sharpest run of damaging storm cells typically landing between March and June. A walk around the outside of the house — checking that gutters are clear, downspouts direct water away from the foundation, and nothing overhanging the roofline is dead or weak enough to come down in a strong wind — takes less than an hour and is far easier to do calmly now than to sort out after a storm has already come through.
Change the AC filter and consider a tune-up before the first 100-degree week
An AC system works its hardest starting in late spring, and a clogged filter is one of the simplest, cheapest things restricting airflow and making the whole system work harder than it needs to for the same result. A basic filter change costs almost nothing and takes five minutes. If the system is a few years old and hasn’t had a spring check, a professional tune-up now — checking refrigerant charge, cleaning the outdoor condenser coil, and confirming the system is actually ready for sustained triple-digit demand — is worth the appointment before the busiest season of the year makes same-week scheduling harder to get.
Check the exterior for what winter and early spring left behind
Caulk around windows and doors that’s cracked or pulled away lets conditioned air leak out right when the AC starts working hardest to keep it in. Exterior paint that’s peeling or chalking on sun-facing walls is easier and cheaper to touch up now than to let another summer of UV exposure make worse. And if the yard’s soil has gone through its usual wet-spring swelling on the area’s expansive clay, this is a good time to check for new gaps between the foundation and the soil line, since catching movement early is how a lot of foundation problems stay a watering-schedule fix instead of becoming a repair bill.
The short version
Test the sprinklers, check the roof and gutters, change the filter, and walk the exterior for anything winter left cracked or loose. None of it takes a full weekend individually, and doing it now, before the heat and the storms and the watering restrictions are all in full effect at once, is the difference between a summer spent enjoying the lake and one spent playing catch-up on a house that wasn’t quite ready for it.
