What a system in Howell has to handle
Your new furnace has eleven months of work ahead of it most years. Heat runs October through May, with winter nights averaging 18°F from December through February. Then the air conditioner takes over for June through August, cooling afternoons that average 80°F. There is barely a break between the two.
Most homes here heat with gas, and whatever you install has to meet the federal minimum efficiency rating for a gas furnace. Power outages are worth planning around too. In 2024, more than a third of Michigan households lost power for at least 24 hours at a stretch. A furnace or air conditioner that starts back up on its own once the power returns is worth asking about.

Michigan requires HVAC contractors to hold a state license.
The license is issued to the contractor by the Board of Mechanical Rules, and it covers the contractor rather than any one job. It stays with them from house to house, not pulled and reissued each time they take on new work.
For an installation like this one, that license is what stands behind the contractor doing the work. But in most cities and counties, putting in a new furnace, air conditioner or heat pump also needs a permit from the local building office, and an inspection once the job is done. That inspection is separate from the state license. It checks that the equipment was actually installed right in this house, not just that the contractor was allowed to install it.

- When should I replace my HVAC system?
- Replace it when repairs keep piling up or a major part fails, like a heat exchanger or blower motor, on a system that is already old. Rising energy bills, rooms that heat unevenly, and a furnace that runs almost constantly are signs it is wearing out rather than just having a bad week. Homes here need heat from October through May, so a furnace that is struggling going into that stretch is worth replacing before it fails on you. A contractor can look at the age and condition of your system and tell you whether repair still makes sense.
- Should I replace my furnace and air conditioner at the same time?
- It is worth considering if both units are old, since they often share the same ductwork and a matched system tends to run better than two units of different ages paired together. It is not a requirement. A furnace and air conditioner can be replaced separately, and a contractor can look at the age and condition of each one and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, checks the ductwork and venting, and sets the new furnace or air conditioner in place. They connect the gas line, electrical, and refrigerant lines as needed, then test the system to confirm it heats or cools correctly and shuts off the way it should. In Michigan, the person doing this work has to hold a state license issued by the Board of Mechanical Rules. A contractor can walk through what your specific installation will involve before the work starts.
