AC, Furnace & HVAC Repair in Highland Park, IL

HVAC Repair in Highland Park, IL

When the air conditioning quits on a hot Highland Park afternoon or the furnace won't fire on a cold morning, SAVA delivers fast, EPA Section 608 Certified HVAC repair throughout Highland Park (ZIP 60035) — including Ravinia, Braeside, Highmoor, Sherwood Forest, and the downtown blocks.

Highland Park homes skew large, older, and architecturally individual — lakefront and ravine properties, historic homes near Ravinia, and substantial renovations that layered modern equipment onto old structures. Multi-zone systems, boiler-plus-AC combinations, and premium brands are the norm rather than the exception, and they demand methodical diagnosis.

AC Repair in Highland Park

Whether your Highland Park home has a standard central air system or a high-efficiency unit, SAVA diagnoses and repairs it. The most common summer AC repairs we handle:

• Not cooling / blowing warm: refrigerant leaks and recharge, failed compressor, thermostat faults.
• Run and start capacitor replacement — the single most common AC failure in summer.
• Condenser fan motor and contactor replacement on the outdoor unit.
• Frozen evaporator coil diagnosis — airflow, refrigerant, and blower causes.
• Blower motor, control board, and thermostat repair and replacement.
• Condensate drain clog and water leak repair.

Multi-zone and mixed-system diagnosis

It's common for a Highland Park home to run a boiler for radiant or baseboard heat, one or two air handlers for cooling, and three or more thermostat zones — sometimes accumulated across decades of renovations. When cooling fails in one wing, we trace the specific air handler, zone valve or damper, and control circuit involved instead of condemning the whole system. We service premium equipment lines and the hydronic side too, so one visit covers the whole mechanical room.

Furnace & Heating Repair in Highland Park

Highland Park winters put real demand on heating systems, and many of the area's furnaces are second- or third-generation equipment — squarely in the window where ignitors, flame sensors, draft inducers, and control boards fail. SAVA prioritizes no-heat calls and services forced-air furnaces and heat pumps across all major brands — Carrier, Trane, Lennox, Goodman, Rheem, and Bryant. We also service hot-water boiler and baseboard systems found in some older and multi-family buildings, and give an honest repair-or-replace assessment before any work begins.
