Heating and cooling work in Michigan needs a mechanical contractor licence from LARA. Check the company on LARA Verify a License.

A new furnace or air conditioner should be sized for your house. Ask whether the contractor runs a load calculation (often called Manual J) or sizes by the old unit.

Ask for a written quote that lists the model numbers, the removal of the old unit, the permit and any duct or electrical work.

Many equipment warranties need registration within a set time after install. Ask who registers it.

Ask what a tune-up includes. A furnace check before winter is common in Michigan.
