Five months of Terre Haute heat, on one system
Your air conditioner works May through September here, five months of afternoons averaging 85°F. That's most of the year it needs to run right.
Vigo County has also seen 22 hail events and 49 damaging wind events over the past ten years, with hail up to 1.75 inches. The outdoor unit sits exposed to that. Any new system installed today has to meet a federal minimum of 13.4 SEER2, so the efficiency floor is already set. What matters is getting a unit sized and installed to handle the summers here and hold up through what the weather brings.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Vigo County decides for itself whether HVAC contractors need a license or a registration, or nothing at all, so the answer depends on the address, not on any state office. Indiana does not test or track HVAC contractors itself, and no state license stands behind this job. Whatever record exists, if any, sits with the local office.
For an air conditioner install, the protection here comes from the permit process rather 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 an inspection once it is done. That inspection is what checks the installation was done right, since there is no license behind it to answer for that.

- What size air conditioner does my house need?
- The right size depends on your square footage, your ceiling height, how much shade your house gets, and how well it holds cool air, not just floor space alone. A contractor will do a load calculation on your specific house to figure this out. Going bigger than what the load calculation calls for does not cool your house faster. It just means the unit shuts off and on more, which leaves the air feeling damp and uneven.
- Should I replace the whole system or just the outdoor unit?
- In most cases you want to replace both at the same time. The outdoor unit and the indoor coil are matched to work together, and pairing a new outdoor unit with an old indoor coil usually means you lose efficiency and may run into problems getting the two to work right together. A contractor can look at the age and condition of your indoor coil and tell you whether it is worth keeping.
- Do HVAC contractors in Terre Haute 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 Vigo County to see what it requires, and ask any contractor you are considering to show you their license before they start work.
