There are a few different steps to installing a new commercial furnace. Once you’ve selected and purchased the properly sized unit, the old one will have to go. This may include replacing a heat pump
or simply removing an old furnace. A furnace cabinet will need to be placed and then connected to power and ducts. The furnace should be firmly bolted to the floor. Ductwork connections and all of the aspects of furnace installation require expert tools and processes. Any leaks could be catastrophic. Improperly installed units will burn out fast and cost way more money in the long run.
