Ernst Heating & Cooling

Ernst Heating & Cooling Ernst Heating & Cooling has been providing innovative solutions for our customers home comfort needs for over half a century.

Al Ernst first opened the doors to Ernst Hardware in 1951. You could find just about anything you needed at Ernst Hardware from paint to appliances to lawn mowers. Starting in 1954 you could even have Ernst Hardware install a furnace in your home. In 1961 you could get an air conditioner, in 1969 a heat pump. In 1984 you could even get a geothermal system installed, which is what we have become kn

own for. Ernst Hardware has long since dropped the "Hardware" and added the "Heating & Cooling", as well as dropping the paint, appliances, and lawn mowers. But after all these years we still install all kinds of products and provide heating and air conditioning repair, replacement and installation services that keep you comfortable in your home.

MEET THE TEAM MONDAY 💙⚽🏡
This week we’re introducing Kris Hall, one of our Comfort Advisors here at Ernst Heating & Cooling!

When homeowners are trying to decide whether to repair or replace their system, Kris is the guy who helps walk them through it all. Basically, if your furnace or AC decides to retire unexpectedly, Kris helps save the day 😄

One of the things Kris enjoys most about working at Ernst is the people and the culture — which makes sense, because he’s the kind of person who makes the workplace better just by being part of it.

Outside of work, Kris is a huge soccer fan. St Louis City SC, watching games, talking soccer… seriously, if there’s soccer on, he probably already knows the score ⚽😄
He also loves spending time outdoors with his wife and their three kids and grabbing food at favorite local spots like Moussalli's Prime and Popeyes Chop House 🥩 But to keep everyone humble, he’ll also happily mix in Waffle House or Jimmy John’s because apparently his restaurant taste ranges from “date night steakhouse” to “give me a sandwich in 30 seconds” 😂

But above all, the biggest milestone in Kris’s life has been celebrating his wife beating breast cancer — something their family is incredibly grateful for ❤️

We’re lucky to have Kris on the Ernst team and appreciate the positivity, care, and experience he brings to our customers every day! 👏

We had some very talented visitors at the office this week! 🇺🇸🎨

A group of 6th–8th graders from St. Paul Lutheran School Hamel, IL - Worden, IL stopped by to help us celebrate America’s 250th birthday by painting our office windows and they did an amazing job!

We loved having these students bring their creativity, energy, and patriotic spirit to our building. The windows look fantastic, and we’re proud to be part of a community that celebrates together.

Be sure to stop by and check out their artwork! ❤️🤍💙

Have you spotted our newest TV commercial yet? 📺

One of our favorite parts of this commercial is that it features the owners’ sons — making this one extra special for our Ernst Heating and Cooling family. ❤️

As a third-generation, family-owned business celebrating 75 years, it means so much to see the next generation be part of the story. We’ve loved hearing all the positive feedback from customers and community members who have seen it on TV!

If you haven’t caught it yet, check it out below and let us know what you think! 👇

We had some very special visitors at Ernst Heating and Cooling this week! 😊

A group of pre-k students from St. Paul Lutheran School Hamel, IL - Worden, IL stopped by to learn more about what we do, and Roger had a great time showing them around the office and warehouse while teaching them about heating, cooling, and all the tools that help us get the job done every day.

The biggest hit of the visit? Watching their teacher take a ride on the forklift — the kids thought it was absolutely hilarious! 😂

Thank you to the students and teachers for spending part of your day with us. We loved sharing a behind-the-scenes look at Ernst Heating and Cooling with such a fun group!
