Eaton County asks a lot of a heating and cooling system
Winter nights here average 19°F from December through February, and homes need heat from October through May, eight months of the year. That is most of the calendar spent leaning on a furnace, so a new one has to be sized to hold a house steady on the coldest nights, not just get by on the mild ones. Summer is shorter but real, with afternoons averaging 80°F from June through August, so whatever you install has to switch over and handle that heat too.
Most homes here heat with gas, which means a new system is likely a furnace and an air conditioner working together, matched to run efficiently across both seasons. Storms are part of the picture as well. Over the past ten years the area has seen 11 winter storms and 11 damaging wind events, and in 2024, more than a third of Michigan households lost power for at least 24 hours at some point. A new install is a chance to plan for that, not just for the temperature swings.

Michigan requires HVAC contractors to hold a state license.
The Board of Mechanical Rules issues that license, and it is tied to the contractor, not to any one job. It follows the person or business from job to job, not a single furnace or air conditioner install.
For an installation like this one, that license covers the contractor. What covers the install itself is the local building office. In most cities and counties in Michigan, putting in a new heating and cooling system needs a permit before the work starts and an inspection once it is done.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they used to, or when the contractor working on it tells you the parts it needs are no longer worth putting money into. Age matters too. A furnace or air conditioner working hard for 8 months of heating and 3 months of cooling a year wears faster than one that only runs part of the year. If your system is struggling to keep up on the coldest nights, when temperatures drop to 19°F, that's a sign it's already behind, not a sign to wait until it fails completely.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it's worth doing together. A furnace and air conditioner installed at the same time are matched to work with each other, and a contractor only has to size the ductwork and connections once. If one of them is much newer than the other, replacing just the older unit makes more sense. A contractor can look at the age and condition of both and tell you honestly whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- The contractor removes the old furnace, air conditioner, or both, and disconnects the wiring, ductwork, refrigerant lines, and gas or electrical hookups tied to it. The new equipment goes in, gets connected to your ducts and power, and is tested to confirm it heats and cools correctly. For a gas furnace, that includes checking the vent and gas line. For an air conditioner, it means charging the refrigerant lines and confirming the system holds pressure. A contractor will walk you through what's specific to your home before the work starts.
