A new system here has to handle eleven months of work
Bloomington asks for heat from October through April and cooling from June through September. That is 11 months out of the year with almost no break between one season and the next. Winter nights average 24°F, cold enough that a furnace or heat pump runs long hours through the coldest stretch. Summer afternoons average 84°F, so the same system has to switch over and keep up on the other end.
48.6% of homes here heat with electricity, which puts real weight on how a new system is sized and installed. Monroe County has seen 9 winter storms and 44 damaging wind events over the past ten years, and statewide, 17% of households lost power for at least a day in 2024. A new install is worth planning around that, not just around the size of the house.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Indiana leaves HVAC licensing to counties and cities, so there is no state license behind this work, only whatever Monroe County itself requires. That means there is no state record to check and no statewide test a contractor had to pass. What applies to a job here comes down to Monroe County's own rules, not anything Indiana tracks.
For an installation, the protection comes from the permit process rather than a license. In most cities and counties, replacing a furnace or air conditioner needs a permit from the local building office, and an inspector checks the work once it's done, including the gas connection if the system runs on gas. That inspection is what stands behind the job in a place like this.

- When should I replace my HVAC system?
- Replace it when repairs start happening every year or when the unit is old enough that a breakdown could leave you without heat or air. Your furnace here works hard from October through April, and a system on its last legs is more likely to fail on one of those cold nights than on a mild afternoon. If a contractor tells you the same repair is needed again, or the parts are getting hard to find, that is your sign to start planning a replacement instead of another fix.
- Should I replace my furnace and air conditioner at the same time?
- If they are close in age, yes, it usually makes sense to do both together. A furnace and air conditioner installed at the same time are matched to work as one system, and replacing only one can leave the other running against equipment it was never paired with. It also means one installation instead of two, so the house is only apart from its system for one job. If your furnace and air conditioner were installed years apart, a contractor can look at the age and condition of each and tell you whether it is worth waiting on the newer one.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner and sets the new ones in place, then connects them to your ductwork, gas line, refrigerant lines and electrical. The new equipment gets tested for airflow, refrigerant charge and safe operation before the job is called done. Depending on the house, this can also mean sealing up old duct connections or replacing a thermostat so it matches the new system. A licensed contractor can walk you through what your specific installation will involve. Monroe County residents should check whether a license is required for the work being done.
