AC, Furnace & HVAC Repair in Des Plaines, IL

HVAC Repair in Des Plaines, IL

When the air conditioning quits on a hot Des Plaines afternoon or the furnace won't fire on a cold morning, SAVA delivers fast, EPA Section 608 Certified HVAC repair throughout Des Plaines (ZIP 60016, 60018) — including Cumberland, downtown Des Plaines, Orchard Place, and the neighborhoods along the Des Plaines River.

Des Plaines is dominated by solid mid-century brick ranches and Georgians, plus condominiums near downtown and the Metra. Most of the housing went up between the 1950s and 1980s, and a large share of the furnaces and ACs serving those homes are 15–25 years old — peak failure age. River-adjacent blocks add a complication: humid basements and crawl spaces that are hard on furnaces, evaporator coils, and condensate systems.

AC Repair in Des Plaines

Whether your Des Plaines 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.

Humidity, condensate, and frozen coils near the river

Basement humidity is a recurring theme in Des Plaines repair calls. Damp basements and crawl spaces accelerate rust on furnace heat exchangers and cabinets, clog condensate drains with biological growth, and contribute to frozen evaporator coils when airflow is marginal. If your AC trips off with water around the furnace, or freezes into a block of ice on humid days, we diagnose the drainage and airflow root cause rather than just thawing it and leaving.

Furnace & Heating Repair in Des Plaines

Des Plaines 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.
