S & S Heating & Cooling | HVAC Services in Chicago, IL 60618

Short cycling, where a furnace turns on and off too frequently, is a common issue in Chicago's climate, often caused by an oversized unit, a clogged filter, or airflow problems. We diagnose the root cause—checking thermostat placement, ductwork, and system sizing—and provide a clear repair plan. For older systems, we may recommend a properly sized, efficient replacement to improve comfort and lower energy bills during our harsh winters.

Our maintenance service is a comprehensive check-up designed to keep your system running reliably and efficiently. We clean critical components, check refrigerant levels, inspect electrical connections, test safety controls, and ensure your thermostat is calibrated. For Chicago homes, we pay special attention to heat exchangers and ignition systems in the fall, and condenser coils and drainage in the spring, helping prevent costly breakdowns during extreme weather.

With over 35 years of experience, we provide honest assessments. If your system is over 15 years old, inefficient, or requires frequent repairs, a replacement may be the most cost-effective long-term solution. We handle the entire process—from helping you select a correctly sized, energy-efficient model for your Chicago home to professional installation and testing—ensuring your new system delivers optimal comfort and reliability for years to come.
