Climate Control FAQs

On Site Companies serve Minneapolis, St. Paul, Rochester, Mankato, Duluth, MN, and surrounding metropolitan areas as well as the St. Louis, Missouri metro.

Bulk orders of restoration equipment (dehumidifiers, air filters, fans, and air movers), portable restrooms, and trailers are available for nationwide delivery for disaster relief efforts.

The number of climate control units depends on a few variables. Topics to consider are surface area, height of a ceiling (if any), power source available, fuel source available, goal of the project, and whether or not only specific areas of your location need climate control.

Climate control is a complex service, so in order to make sure you have the most efficient plan we strongly recommend that our customers talk over their needs with a sales representative before confirming an order.  Please contact us directly for more information.

The most frequent reason for a ground heater not properly starting is user error. Please refer to our troubleshooting guide before requesting a technician to be dispatched.

We have climate control equipment specifically designed for this type of use. Please contact us directly to find the solution that is best for you.
