We always enjoy being part of events that bring our community together. Seeing familiar faces, meeting new people, and celebrating alongside our neighbors is one of the many reasons we’re proud to call this area home.

Shouting out Matt B from our commercial department!!

Matt has been putting in some outstanding work lately!

He’s been doing a great job on the QuikTrip remodel projects, helping keep things moving and delivering quality results every step of the way. On top of that, he’s also been lending a hand in the Cape area, where he’s taken on a sizable ductwork project at the Culligan plant that’s progressing extremely well.

We appreciate team members like Matt who are always willing to step up, tackle new challenges, and go wherever they’re needed to help the team succeed.

Great work, Matt! Keep it up! 👏

🏆 Honored to Support Our Community 🏆

Recently, we had the privilege of attending the Cape Girardeau Noon Optimist Club meeting, where Crystal Heating & Cooling was recognized with a plaque for being a Presenting Sponsor of Chili Day 104.

While we’re grateful for the recognition, what stood out most was learning more about the impact this organization has on our community. Through fundraising efforts and volunteer work, they help support youth programs, playground projects, sports leagues, community recreation, and so much more. The funds raised stay right here in our area, helping create opportunities for local kids and families.

As a locally owned business, we believe strong communities are built when people invest in one another. We’re proud to have played a small part in supporting an event that helps make those investments possible.

A sincere thank you to the Cape Girardeau Noon Optimist Club for all they do behind the scenes to make our community a better place.

The Customer Shout-Outs for Jack keep rolling in and we want to share them!!!

The best recognition comes from the people we serve.

We recently received this feedback from Pat at Patrick Furniture:

“Jack was very well prepared, very knowledgeable (even when he reached out for help from a supervisor, he did so to be sure of the proper diagnosis), well-mannered, and carried himself amazingly maturely for such a young guy.”

Comments like this speak volumes. Technical knowledge is important, but so is professionalism, humility, and the willingness to double-check your work to ensure the customer gets the right solution. Jack demonstrated all of those qualities.

One thing we especially appreciate is that he wasn’t afraid to reach out for a second opinion to confirm his diagnosis. That’s not uncertainty—it’s commitment to getting it right.

We’re proud to have team members who represent Crystal Heating & Cooling with integrity, professionalism, and a customer-first mindset.

Great work, Jack! Thanks for making us proud and taking care of our customers the right way. 👏

Nothing says commercial HVAC quite like washing chillers with a storm rolling in. ⛈️😅

While most people are heading for cover when they see dark clouds, our team was out making sure these chillers were cleaned and ready to perform their best.

Chiller maintenance is a critical part of keeping large facilities running efficiently, and sometimes the weather doesn’t exactly cooperate. Thankfully, our crew knows how to roll with it and get the job done.

The storm may have added a little excitement to the day, but seeing those coils clean and the equipment operating at peak performance makes it worth it.

A clean blower wheel can make a BIG difference in a commercial HVAC system. 💨

Here’s a look at a blower wheel cleaning on one of our commercial units. Over time, dirt and buildup can reduce airflow, decrease efficiency, and put extra strain on the system.

Routine maintenance like this helps keep equipment running smoother, improves performance, and can even help extend the life of the unit.

It’s not always the glamorous side of HVAC — but it’s the kind of detailed work that keeps businesses comfortable and systems operating the way they should.

Thanks Tj, for all your hard work!
