What’s one of the most expensive HVAC repairs a homeowner can face, and is there anything you can do to help prevent it? Jeremy’s answer: the compressor. The good news is that simple things like regularly changing your air filter, keeping your outdoor unit clean, and staying on top of routine maintenance can help protect it. Jeremy breaks down what homeowners should know to help avoid one very expensive HVAC repair.
Thank you for the 5 star review Rose! ⭐️ We appreciate your business!

When a Realtor refers us to her clients, that hits a little different.
🏡💙
Regina has been sending her clients our way for several years and when your own reputation is attached to every recommendation you make, that kind of trust means a lot.
Thank you, Regina, for another referral, another ⭐⭐⭐⭐⭐ review, and for continuing to trust our team to take care of your clients!
And Regina…we saw that part about the missing taco gift certificate. 😂🌮 We might need to fix that.

This is the kind of stuff we LOVE about our community. ♥️
We teamed up with The Rack House for a tournament supporting our Wentzville firefighters and had a blast!
🙌⛳️🚒
Local businesses supporting local heroes, neighbors supporting neighbors, and everybody coming together for a good cause. Our community is pretty freaking awesome. 🥰
We’re proud to be a small part of it!

Well….this is interesting. 👀
There’s a brand-new furnace sitting in one our Stay Cool trucks…and it’s not headed where you might think!
🔥 Something BIG is coming.
ANY GUESSES?

Not all heroes wear capes… some carry gauges. 🦸♂️🦔❄️
When the heat went out and one little hedgehog needed the temperature just right, Jeremy came to the rescue.
Just another day at Stay Cool Climate Control…saving comfort, one customer (and apparently one hedgehog) at a time. 🌮💙
