AC Repair, Furnace Repair and HVAC Service in Westchester, IL

SquareHVAC handles cooling and heating calls in Westchester from its Hillside home base. This page focuses on diagnosing a failure first and on the Village steps that matter if the answer is new equipment.

AC repair in Westchester

If cooling disappears in a Westchester home, note whether air still comes through the vents and whether the outside unit starts. Water, ice or a new sound is useful to report as well. Our air conditioner repair service begins with finding the cause, rather than assuming the whole unit must be changed.

Before you call, check the thermostat setting, the air filter and the breakers. Our filter guide shows how to check a filter. If you see ice on the unit, switch the cooling off and let it melt before anyone works on it.

Furnace repair and furnace installation

• Furnace repair: no heat, weak heat, a furnace that starts and stops, or a new smell or noise.
• Furnace installation: when the old furnace is no longer worth repairing. Our guide to 80 AFUE and 96 AFUE furnaces explains the two common efficiency levels before you choose.
• Boiler service: for homes heated with radiators or hot-water baseboards.

A Westchester repair and replacement decision

For a cooling complaint, first separate a system that does not turn on from one that runs without lowering the temperature. Record whether the outdoor unit starts and whether you see ice, water or a new sound. If ice is present, turn cooling off so it can thaw before inspection. A repair recommendation should follow a diagnosis; the age of the home by itself does not tell us which equipment or ducts are installed today.

If replacing the air conditioner or furnace is the better option, Westchester’s residential HVAC permit form calls for a final inspection. It also sets a placement rule for an outdoor AC unit: at least 15 feet from the neighboring house. Ask about that space before choosing a proposed condenser location. A written quote should make clear which parts of the project are included, especially when an existing unit is being moved or replaced. The Village permit form is linked in the local information below.
