Evanston doesn't ask much of an air conditioner

Summer afternoons here average 76°F. That's mild, and it's why the conditions here place so little demand on cooling to begin with.

If you're installing central air anyway, whether to replace an old unit or add one for the first time, it still has to meet 13.4 SEER2, the federal minimum for systems built since 2023. Beyond that minimum, the system should be sized to your house rather than to a hotter climate it will never see here.

What size air conditioner does my house need?
The right size depends on your square footage, your insulation, how many windows you have, and which way they face. A unit that's too big cools the room fast but shuts off before it pulls the moisture out of the air, so the house feels damp. A contractor works this out with a load calculation, not a chart based on square footage alone, and that's the only way to get the number right for your house.
Should I replace the whole system or just the outdoor unit?
If your indoor and outdoor units are original to each other, replacing just the outdoor unit usually isn't a good idea. The two are matched to work together, and pairing an old coil with a new condenser can hurt efficiency and shorten its life. A contractor can check the age and condition of what you have and tell you whether the indoor unit is worth keeping.
Do HVAC contractors in Evanston need a state license to work on my home?
Ask to see a contractor's license number before work starts, and check that it's current. A licensed contractor also carries the insurance that protects you if something goes wrong during the job. If you're not sure a license is valid, you can confirm it before signing anything.
