Evanston has about 76,000 residents and 34,000 homes, and half of those homes were built before 1953. That housing is older than in about 93% of the 774 U.S. cities of 50,000+ people in our data. Cook County is in climate zone 5A (cool, humid), which shapes what heating and cooling work involves here. Here is what that means for your project, plus permit and license tips and questions to ask before you hire.

Before you hire for heating and cooling work in Evanston
Census estimates put the median build year in Evanston at 1953; about 46% of homes were built before 1950. Many older homes were built for radiators, floor furnaces or window units, so adding or replacing central air can mean new ductwork or a ductless system. Ask the company to look at what the house has now before quoting.
Cook County is in IECC climate zone 5A, a cool, humid climate, on the U.S. Department of Energy's county map. Heating carries most of the load here. If you are considering a heat pump, ask whether the model is rated for cold climates and how backup heat works. In a humid climate, ask how the system will control indoor humidity, not just temperature. Whatever the climate, ask for a room-by-room load calculation (ACCA Manual J) instead of matching the size of the old unit.
About 75% of occupied homes in Evanston heat with utility gas and 19% with electricity. Many replacement quotes will involve a gas furnace or boiler; if you are thinking about switching to an electric heat pump, ask whether your electrical panel needs an upgrade.
About 50% of homes in Evanston are in buildings with five or more units. Apartments and condos may have their own systems or share a central one, so check what your building allows before replacing equipment.
Permits and licenses in Evanston
Replacing a furnace, air conditioner or heat pump usually needs a mechanical permit and a final inspection. In Evanston, permits come from the city's building department, or from Cook County for addresses outside city limits. Ask the company who pulls the permit, and keep a copy of it.
Illinois has no statewide general contractor license; IDFPR licenses roofing contractors. For other trades, ask your city or county building department which license applies, and ask the company for its license number.
