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 known 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.

Some heroes wear tool belts and turnout gear. 🔧🚒

Happy National First Responders Day! Today we’re giving a big shoutout to Adam, one of our very own installers, who also volunteers as a firefighter with the Mt. Olive Fire Department with his dad. We’re so proud to work alongside you, Adam!

Thank you to all of the first responders who keep our communities safe. 💙

This review made our day. ❤️

A service call can feel stressful, especially when you don’t know what to expect. Jessica told us that Ramon’s friendliness and professionalism turned a stressful appointment into a positive experience. That’s the kind of care we want every customer to feel. Thank you, Jessica, and thank you, Ramon, for representing Ernst so well!

MEET THE TEAM MONDAY 💙🔧🏈
This week we’re introducing Ryan, one of our Service Installers here at Ernst Heating & Cooling!

Ryan has been with Ernst for about 3.5 years. He originally started in maintenance before moving into service install. Once one of our technicians diagnoses an issue, Ryan may be the guy getting sent out to take care of the repair and get things back up and running. 🔧

One of the things Ryan likes most about Ernst is that we believe in doing things the right way. No cutting corners, no bad practices - just taking pride in doing the job right. 💙

Ryan enjoys spending time with his mom, sister, and girlfriend. He’s also an all-music kind of guy, so his playlist probably has a little bit of everything! 🎶He’s a football fan and follows the Rams 🏈, and when he’s relaxing at home, The King of Queens is a favorite (who doesn't need a little Doug Heffernan in their life?) As for snacks, Cheez-Its are the go-to, and when it comes to food, Ryan is a big-time pizza fan. 🍕🧀

We’re glad to have Ryan on the Ernst team and appreciate the hard work he puts in to get our customers’ systems back up and running! 💙👏

There’s only a little over a week left, so sign up by October 31. Your home stays comfortable, and a local patient gets a little help along the way. 🏠🎀

Meet the Team Monday: Missy, Lead Dispatch 📋📱

Every morning, before the first truck rolls out, Missy has already set the board. As our Lead Dispatch, she’s the hub of our operations. She makes sure the right technician gets to the right customer for the right job, every customer, every day. She calls it a puzzle that keeps shifting all day long, and she’s the one who makes the pieces fit. She supports our techs in the field, keeps customers in the loop, and keeps everything moving.

Missy is a proud mom of four (two boys and two girls, ages 19 to 28), and her favorite family time is cheering at sporting events or sitting around the table for a big family dinner. There’s a lot to celebrate this year: her oldest daughter is getting married next year! 💍

Some fun facts about Missy:
🏒 You’ll find her at Blues games, and on football Sundays she’s cheering for the Colts.
👠 She admits to a “shoe shopping problem.” She could wear a different pair every day for a month and never repeat.
🎄 She’s a Christmas fanatic. Putting up the tree is her favorite tradition, and it’s going up THIS WEEK!
☕ She runs on coffee, and Scooter’s is her go-to.
🥗 She’s on a healthy kick and has been crushing her meal prep… but she will never give up ice cream.
🥩 She says she could give up meat forever and be just fine.

Missy says her favorite part of working at Ernst is the atmosphere and the family feel. We’re lucky to have her keeping us all on track!

Drop a comment and say hi to Missy! 👋
