☀️ This Week's Weather Forecast for Stillwater & Surrounding Areas
Summer is making itself known this week! We've got plenty of sunshine, temperatures pushing the upper 90s midweek, and a chance for thunderstorms on Thursday before a pleasant weekend settles in.
🌡️ Highs range from 80° to 97°
⛈️ Best chance for rain: Thursday
🌙 Warm evenings all week long
💡 Tip of the Week:
Change your air filter monthly during the summer. A clean filter helps improve airflow, keeps your system running efficiently, and may even help lower your energy costs.

🥵 HEAT ADVISORY 🥵
Oklahoma summer has officially arrived.
If your air conditioner is already struggling to keep up, this week's heat isn't going to make things any easier.

Now is the time to:
✅ Change your filter
✅ Clear debris around your outdoor unit
✅ Address small AC issues before they become major breakdowns

Don't wait until your house is 85° inside to find out your system wasn't ready for summer.
Stay cool, Oklahoma. ❄️

☀️ Oklahoma Fun Fact ☀️

When it comes to staying cool, Oklahoma is leading the way.

According to recent U.S. Census Bureau data, Oklahoma is tied for the highest percentage of air-conditioned homes in America alongside Florida and Delaware. 🇺🇸❄️

Honestly, that's probably no surprise to anyone who's spent a June afternoon in Oklahoma.

As summer temperatures continue to climb, we're grateful to help families across Stillwater, Perkins, Cushing, Perry, Morrison, and the surrounding communities stay comfortable when the heat arrives.

Stay cool, Oklahoma!

☀️ Another hot Oklahoma week is ahead!

We're looking at plenty of sunshine and temperatures climbing into the low-to-mid 90s throughout the week, with a few chances for thunderstorms returning as we head toward the weekend. ⛈️

With temperatures pushing into the mid-90s, your air conditioner is about to earn its keep. If your system has been struggling to keep up, running longer than normal, or causing higher electric bills, now is a great time to have it checked before the hottest part of summer arrives.

🌡️ Highs reaching 95°
☀️ Mostly sunny conditions
⛈️ Storm chances increase later in the week
🌙 Warm summer nights in the upper 60s and 70s

Stay cool, enjoy the sunshine, and have a great week from your local team at OnSite Heat & Air.

🔥 Oklahoma is reminding us that summer has officially arrived.

We're looking at a hot start to the week with temperatures climbing into the mid-90s before storm chances return later in the week and bring a little relief from the heat. ⛈️

Now is a great time to make sure your A/C system is ready for the long Oklahoma summer ahead. The hottest days of the year are still to come.

Stay weather aware, enjoy the week, and as always...
