🔥 3 HOT DAYS… THEN RELIEF IS COMING! 🙌
Oklahoma isn’t quite finished with summer yet! We’re starting the week with three straight days above 100°, but there’s finally some relief showing up in the forecast.
⛈️ Storm chances move in Wednesday night into Thursday, bringing Thursday’s high down to around 94° and overnight temperatures into the low 70s. We’ll take it!
❄️ HVAC Tip of the Week: Your A/C Needs Airflow!
During extreme heat, your system needs all the airflow it can get. Restricted airflow makes your A/C work harder and can reduce its ability to keep your home comfortable.
✔️ Keep your air filter clean
✔️ Make sure return vents aren’t blocked
✔️ Keep supply vents open
✔️ Avoid closing off rooms or multiple registers trying to redirect air
Good airflow = better comfort and a happier A/C!
Hang in there through the first few hot days — cooler weather is on the way! ☀️➡️⛈️

🔥 BACK TO TRIPLE DIGITS! 🔥

Well… our little break from the extreme heat was nice while it lasted! 😅

We’re kicking off the week at 103° Monday and 102° Tuesday, with temperatures hanging right around 100° through the rest of the week.

❄️ Tip of the Week: Don’t crank it way down!

Setting your thermostat to 65° won’t make your A/C cool your home any faster. Your system can only remove heat at a certain rate, and during 100°+ Oklahoma weather, it may run for long periods — or even continuously during the hottest part of the day.

👉 Pick a reasonable thermostat setting and let the system do its job. Constantly lowering the temperature doesn’t increase its cooling capacity.

And remember: long run times during extreme heat don't automatically mean something is wrong. Your system is working against some serious outdoor conditions!

Stay cool, stay hydrated, and give that A/C some credit this week — it’s about to earn its keep! 💪❄️

Great review from peter... "We have had OnSite service our air and heat in our house for over two years on a sixth month interval, as well as service some issues due to extended air conditioning use this summer. They have been universally excellent, not just in the repairs and maintenance, but in ease of scheduling communication and all interactions. We recommend them highly!"

Great review from Manote... "Great company and great techs. This company saved me $4,000.00. Another local company quoted me 7,800.00 to install my mini split. Don’t look anywhere else."

☀️ Highs BELOW 100°?! We’ll Take It! 🙌

After the stretch of extreme Oklahoma heat, we’re definitely thankful for some lower temperatures this week!

We’re looking at highs in the mid-to-upper 90s for most of the week. Still hot? Absolutely. But after the temperatures we’ve seen lately, every degree helps — for you AND your A/C! ❄️

🔧 Tip of the Week:
This little break in the extreme heat is a great time to give your HVAC system a quick check:

✔️ Check or replace your air filter
✔️ Clear grass, leaves & debris away from the outdoor unit
✔️ Make sure supply and return vents are open and unobstructed

Your A/C has been putting in some serious work this summer. A little attention now can help it finish the season strong. 💪

Enjoy the “cooler” Oklahoma weather this week! 😎
