Sisseton Public School

Sisseton Public School

Located in Sisseton, South Dakota. We know how important the school is to the local community and how important temperature is for learning. That is why we were dedicated to getting this project right. The school recently reported that it had 250 students.

“I had called another company to try to figure out why all 4 of our units would not function.  The other company spent 4 hours and misdiagnosed the issue suggesting I needed to call an electrician.  I had a hunch this was bad advise and got a hold of Baete-Forseth.  Their tech Jayson showed up the same day and after 2.5 hours correctly diagnosed the issue and got all the units running with no parts required!  If you have a complicated commercial system do not call anyone else!”
