A new system here has to cover eleven months a year
Grand Rapids gets a real break from heating or cooling in just one month. Winter nights average 19°F from December through February, and a furnace sized for that has to keep up through the coldest stretch without strain. Summer afternoons average 81°F, so the cooling side still matters even though it only runs three months, June through August.
Most homes here heat with gas, and whatever you install has to meet the federal minimum efficiency set for this region. Michigan also sees its share of winter storms and wind, and in 2024 more than a third of households lost power for at least a day. Worth asking how a new system handles an outage in the middle of winter.

Michigan requires HVAC contractors to hold a state license.
The Board of Mechanical Rules is who tests and licenses these contractors in Michigan. That license belongs to the contractor, not to any one job, so the same license should cover whatever else they do in your home. It means the state has tested this person and keeps a record of them, not just a business filing.
For a heating and cooling installation, that license is what stands behind the work itself. In most cities and counties here, the job also needs a permit from the local building office, and an inspector checks it once it's done. That inspection is separate from the license. It is what catches a bad connection or a wrong hookup before you are living with it.

- When should I replace my HVAC system?
- Replace it when repairs get more frequent, the equipment is old, or it can't keep the house comfortable anymore. A furnace that needs a service call every winter is telling you something, especially with lows around 19°F here from December through February. Age matters too. A furnace or air conditioner working hard past 15 years is more likely to fail at the worst possible time. If a contractor is proposing a repair that costs a large share of what a new system would run, replacement is usually the better move.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, and here's why it matters more than in most places. Homes in Grand Rapids need heat or cooling 11 months out of the year, so both systems are working hard on a short break between seasons. A furnace and air conditioner installed at the same time also age together, so you're not stuck matching new equipment to an old system built for a different refrigerant or airflow. If one unit is much newer than the other, replacing only the failing one still makes sense. A contractor can look at both and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner, or both in place, and connects it to your ductwork, gas line, refrigerant lines, and electrical. They'll check the ducts for leaks or sizing issues while everything is open, since a new system moving air through undersized or leaky ducts won't perform the way it should. Once it's connected, they test it, a furnace on a heating cycle, an air conditioner on a cooling cycle, and check refrigerant charge and airflow before calling the job done. Michigan requires the contractor doing this work to hold a state license through the Board of Mechanical Rules, so it's worth confirming that before the work starts.
