Five months of Evansville heat, every year
Your air conditioner works May through September here, with summer afternoons averaging 87°F. That is five straight months of running, not the occasional hot week, and the unit you install needs to hold up to that stretch every year it's in your home.
Vanderburgh County has also seen its share of hail and wind, 19 hail events and 103 damaging wind events over the past ten years. A new outdoor unit sits outside through all of that. Any central air conditioner installed new today has to meet a federal efficiency minimum of 13.4 SEER2, so that's the floor to expect no matter who installs it.

In Indiana, HVAC licensing for homes is left to the counties and cities.
That leaves Vanderburgh County to set its own rule, if it has one, rather than the state. There is no state exam behind this and no state record of who is licensed to do the work. Whatever protection exists here comes from what the county or city requires on their own, not from Indianapolis.
For an air conditioner install, that protection is more likely to show up as a permit than a license. In most cities and counties, putting in a new air conditioner needs a permit from the local building office, and the work gets inspected once it is done. That inspection is what catches a bad install here, not a license number, since the state does not issue one.

- What size air conditioner does my house need?
- The right size depends on your square footage, your ductwork, how much shade and sun your walls and windows get, and how well the house holds conditioned air. A contractor works this out with a load calculation, not a chart based on home size alone. Putting in a unit that's too big cools the air fast but shuts off before it pulls the humidity out, so the house feels damp. Too small, and it runs constantly through the summer, since afternoons here average 87°F, and still can't keep the house comfortable.
- Should I replace the whole system or just the outdoor unit?
- If your furnace or air handler is old, replacing only the outdoor unit can cause problems even when the parts technically connect. Indoor and outdoor units are matched to work at a specific capacity and airflow. Pair a new outdoor unit with an old indoor coil and you can lose efficiency and put more strain on the new compressor, sometimes enough to affect the warranty. A contractor can look at the age and condition of your indoor equipment and tell you whether it can pair with new outdoor equipment or whether replacing both makes more sense.
- Do HVAC contractors in Evansville need a state license to work on my home?
- Indiana doesn't license HVAC contractors at the state level. That's handled by the county or city instead, so whether a license is required for work on your home depends on Vanderburgh County's own rules. Ask any contractor you're considering to show their license and insurance before they start work.
