HVAC Services Norridge IL | Call Cnn Heating & Air Conditioning

Before calling for service, check that your thermostat is set to 'heat' and the temperature setting is above the current room temperature. Also, ensure the circuit breaker for the boiler hasn't tripped. If these are fine, the issue could be with the pilot light, pressure levels, or a faulty component. It's best to shut off the system and call a professional for diagnosis to prevent further damage or safety hazards.

Thermostat malfunctions are common and can stem from dead batteries, accumulated dust inside the unit, or incorrect calibration. First, try replacing the batteries. If that doesn't resolve it, the wiring or the thermostat's internal sensors may be failing. Our technicians can quickly test your thermostat, recalibrate it, or recommend a reliable replacement to restore accurate temperature control in your home.

We prioritize no-heat emergencies, especially during freezing weather. For our Norridge customers, we strive for same-day or next-day service. When you call, we'll assess the urgency and dispatch one of our local technicians as quickly as possible to get your heating system—whether it's a boiler or furnace—operating safely and efficiently.
