Tessiers

Tessiers is a Sioux Falls-based HVAC contractor and mechanical contractor delivering design-build, installation, and service for complex heating and air conditioning systems across commercial and industrial facilities. As an air conditioning contractor, air conditioning repair service, air conditioning system supplier, heating contractor, and heating equipment supplier, they handle diagnostics, replacements, retrofits, and preventive maintenance with an emphasis on energy-efficient solutions and controls integration. Their in-house metal fabricator and welder teams produce custom sheet metal ductwork, fittings, and supports to tight tolerances, helping compress timelines and ensure a precise fit on fast-track projects. For faster turnaround, share your plans or equipment model numbers to request a scoped quote, ask for a site assessment and preventive maintenance program, and confirm lead times and emergency response options before scheduling.
