Four months of real heat in Bloomington
Summer afternoons here average 84°F, and that runs from June through September. A new air conditioner has to hold a house steady through all of it, not just the hottest week. Every new one sold now has to meet 13.4 SEER2, the federal minimum, so that part is settled before you even start comparing units.
What matters more here is what sits outside. Monroe County has logged 32 hail events and 44 damaging wind events over the past ten years, with hail up to 2.75 inches. The outdoor unit takes that weather directly, so how it is installed, and what protects it, is worth asking about.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Monroe County sets its own rule on who can do this work. Indiana does not test or record HVAC contractors itself, so there is no state license number to check on a job like this one. Whether a permit or inspection is required here comes from the county or city, not from any state file.
On an air conditioner installation like this one, most cities and counties require a permit from the local building office before the work starts and an inspection once it is done. That inspection is what confirms the unit was installed correctly. Indiana leaves that check to the county, not to a state license.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a chart based on square footage. A contractor measures your windows, insulation, ceiling height, and how much shade your house gets before recommending a size. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy even at the right temperature. One sized too small runs constantly during those 84 degree afternoons and still cannot keep up.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are more than a few years apart in age, replacing just the outdoor unit usually causes problems. The two parts are matched to work together, and pairing a new condenser with an old coil can mean lost efficiency or a mismatch the manufacturer will not warranty. New central air conditioners now have to meet a 13.4 SEER2 minimum, and an old coil was not built to work with that. A contractor can check your coil's condition and tell you whether it can pair with new equipment or whether it makes more sense to replace both.
- Do HVAC contractors in Bloomington need a state license to work on my home?
- Indiana does not license HVAC contractors at the state level. That is handled by the county or city instead, so whether a license is required depends on where you live. Check with Monroe County directly to find out what it requires for HVAC work on your home.
