What a system in Ingham County has to handle
Your new furnace will run from October through May here, eight months of the year. Winter nights average 19°F from December through February, cold enough that the furnace is doing real work most of the night, not just holding steady. Whatever you install has to be sized for that low, not for an average day.
Summer asks less of a system here, three months of cooling against afternoons averaging 80°F. That leaves eleven months a year where the house depends on either the furnace or the air conditioner working. Michigan sees its share of winter storms and wind, and over a third of households in the state lost power for at least a day in 2024. A furnace with a standing pilot will relight itself when the power comes back. One with electronic ignition needs the switch flipped, worth knowing before the first cold night after an outage.

Michigan requires HVAC contractors to hold a state license.
The Board of Mechanical Rules issues that license, and it covers the contractor, not each job. It does not mean every installation gets a separate check from the state. Holding the license means Michigan tested and records this contractor. It is not a sign-off on this particular furnace or air conditioner.
For an installation like this one, the permit is what covers the job itself. In most cities and counties in Michigan, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and an inspection once the work is done. The license accounts for who is allowed to do the work. The permit and inspection account for whether this job, in this house, was done right.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth, or when it can't keep up anymore. A furnace or air conditioner that needs a major repair, like a heat exchanger or a compressor, is usually not worth fixing on an older unit. Rising bills for no clear reason, uneven heating or cooling room to room, and needing a technician out every season are all signs the system is wearing out rather than just having a bad week. Homes here need heat or cooling 11 months out of the year, so a system on its way out doesn't get much rest to hide the problem.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, it's often worth doing together, but it depends on the condition of each one. A furnace and air conditioner installed at the same time tend to wear out around the same time too, so if one is failing the other may not be far behind. Replacing both together also means the new equipment is matched to work as one system, which can matter for efficiency. But if your air conditioner is only a few years old and your furnace is the one failing, there's no reason to replace a unit that's still got years left in it. A contractor can look at both and tell you honestly whether one or both make sense.
- What happens during an HVAC installation?
- A contractor first sizes the equipment to your house, since a furnace or air conditioner that's too big or too small won't heat or cool evenly. The old equipment gets disconnected and removed, then the new unit is set in place and connected to the ductwork, gas or electric lines, and in the case of an air conditioner, the refrigerant lines running to the outdoor unit. Once it's hooked up, the contractor tests it, checking airflow, temperature output, and that everything is running safely, before walking you through anything you need to know about operating it.
