I called at 7:30 and reached someone about my cold house, and told them I have a day care here, and really need heat. 90 minutes later, the service tech, Aaron, has been here, replaced the part, and left, and the kids are toasty warm. Thanks for excellent service, CW Suter!

L&L Builders Co.

L&L Builders Co. would like to personally thank you and your Suter team for their many positive contributions and commitment on the recently completed Bar Louie project. As a thoughtful subcontractor, we could have asked for little more from your team as you had it going on in both the field and in the office. We appreciated your team’s engagement, planning, flexibility and proactive responses to project changes, as there were many. You were an exceptional partner on this challenging project, and your actions surrounding safety, quality and timely completion of work was greatly appreciated.

All the best to your team and thanks again.

Just want you to know what a great job Brennen did yesterday. He’s a great guy! Courteous, took the time to explain what he was doing and what was wrong. He even drove back to Sioux City to get the part he needed to get the heat going. It is much appreciated!

Fantastic service! Have found my new HVAC services company: Customer service is what it's all about, and you guys nailed it. It also helps that the issue was immediately diagnosed and corrected, meaning my house is now cool and dry!
