Three months of real heat, then a long rest
Summer here runs June through August, with afternoons averaging 83°F. That is the stretch a new air conditioner has to handle, and it needs to handle it well, since a unit sized or installed wrong will run long hours trying to keep up on the hottest days.
Anderson has also seen its share of hail and wind over the past ten years, so the outdoor unit needs to sit somewhere it is not exposed to every storm that comes through. Any central air conditioner installed new today has to meet a federal minimum of 13.4 SEER2, so that baseline is already covered. What matters after that is getting the size and the installation right for the house it is cooling.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Madison County sets its own rule on who can do HVAC work, since Indiana leaves that to cities and counties instead of licensing contractors at the state level. That means there is no state record to check either way. Whether a local license is required here depends on the city or township the house is in, not on any statewide standard.
For this installation, the permit is what carries the weight a license would elsewhere. 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 confirms the unit was installed correctly, not a license number.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not the square footage of your house alone. A contractor looks at your insulation, your windows, how many rooms face the afternoon sun, and your duct layout before landing on a number. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so rooms feel damp. Undersized, and it runs nonstop on the hot afternoons here and still can't keep up. Have a contractor run the calculation on your actual house rather than going by the unit that's in there now, since the last one may have been sized wrong too.
- Should I replace the whole system or just the outdoor unit?
- In most cases, if your outdoor unit is failing, the indoor coil should be replaced with it. New outdoor units use a different refrigerant and pressure than older systems, and the old indoor coil usually isn't built to match. Pairing a new condenser with an old coil can mean poor cooling and a shorter life on the new equipment. A contractor can check whether your indoor coil is compatible, but a matched system is what carries the warranty on new equipment.
- Do HVAC contractors in Anderson need a state license to work on my home?
- Indiana doesn't license HVAC contractors at the state level, that's handled county by county. Anderson sits in Madison County, so whether a license is required comes down to the county's own rules. Ask any contractor you're considering directly whether they hold what Madison County requires, and confirm it before work starts.
