Four months of real heat, and hail every summer
Omaha asks for cooling June through September, and summer afternoons average 84°F. That is not a long season, but a new system still needs to be sized right for the days it works hardest.
Douglas County has seen 131 hail events over the past ten years, with stones as large as 3.75 inches, plus 138 damaging wind events in that same stretch. An outdoor unit sits exposed to all of it, so where it goes and what protects it matters. Any new central air conditioner installed now has to meet the federal minimum of 13.4 SEER2.

Nebraska requires contractors to register with the state.
Nebraska's registry is a business record, not a test of skill. The Department of Labor keeps the contractor's name and business information on file, but nobody at the state checks their work or their knowledge of the trade before they take that job.
For an AC installation, the protection here comes from your local building office. In most cities and counties in Douglas County, this job needs a permit before work starts and an inspection after it is done, and that inspection is what checks the work itself, since the state registration does not.

- What size air conditioner does my house need?
- There's no single number that fits every house. Square footage alone gets it wrong more often than not. The right size depends on your square footage, how much insulation you have, how many windows face the sun, and the layout of your ductwork. A contractor works this out with a load calculation, not a guess. An oversized unit cools the air fast but shuts off before it pulls the humidity out. An undersized one runs nonstop on Omaha's hot afternoons without ever catching up.
- Should I replace the whole system or just the outdoor unit?
- In most cases you replace both the outdoor unit and the indoor coil together. The two are matched to work at a specific efficiency and capacity. Pairing a new outdoor unit with an old coil usually means you lose the efficiency you're paying for, and it can void the warranty or cause problems with the refrigerant. If your indoor coil is old enough that the outdoor unit needs replacing, it's usually near the end of its own life too. A contractor can look at both and tell you whether the coil is worth keeping.
- Do HVAC contractors in Omaha need a state license to work on my home?
- Nebraska doesn't license HVAC contractors the way some states do. Contractors have to register with the state Department of Labor. That's a business record, not a trade exam. What matters more for a job like this is the local permit. Most cities and counties require a permit and inspection when you replace an air conditioner, and that inspection is what confirms the work was done right.
