Two months of real heat, and a code that changed in 2023

Geneva only asks a lot of an air conditioner for two months a year, July and August, with summer afternoons averaging 79°F. That short season still means the unit has to be sized right. Too big and it cools the air fast but never runs long enough to pull the moisture out. Too small and it runs flat out on the hottest afternoons and can't keep up.

If you're installing new, the unit has to meet 13.4 SEER2, the federal minimum for central air conditioners built since 2023. That's the baseline now, not an upgrade.

Going above the federal minimum saves little here, about $20 a year.

What size air conditioner does my house need?
The right size depends on your home's square footage, insulation, window area, and layout, not just a rule of thumb. A unit that's too big cools the air fast but shuts off before it pulls the moisture out, leaving the house clammy. One that's too small runs constantly and still can't keep up on the hottest afternoons. A contractor will run a load calculation on your actual house to get the size right.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit are close in age, replacing just the outdoor unit usually isn't worth it. The two are matched to work together, and pairing a new condenser with an old coil can hurt efficiency and shorten the life of the new equipment. Refrigerant type is another issue, since older systems may use refrigerant that isn't compatible with new units. A contractor can look at both pieces and tell you whether a matched replacement makes more sense.
Do HVAC contractors in Geneva need a state license to work on my home?
Yes. Anyone installing or servicing central air conditioning in your home should hold a valid state HVAC license. Licensing means the contractor has met required training and testing standards, and it also gives you recourse if the work doesn't hold up. Ask to see the license number before work starts, and confirm it's current.
