HVAC Repair Des Plaines IL | Call NJL Heating and Air Conditioning

This is a common problem in our area, often caused by a clogged condensate drain line. Humidity and algae can build up in the line, causing a safety switch to trip and shut down your furnace. At NJL, our HVAC technicians are trained to quickly diagnose this issue. We'll clear the blockage, clean the line to prevent future problems, and ensure your system is operating safely and efficiently, getting your heat back on without unnecessary upsells.

Many home comfort systems are interconnected. A water heater involves plumbing, gas lines, and sometimes electrical connections. Our technicians are cross-trained in HVAC, plumbing, and electrical work, which allows us to handle the entire job correctly and efficiently. For example, when we install a new water heater, we can manage the plumbing connections, gas line safety checks, and any electrical requirements, ensuring a seamless and code-compliant installation from a single, trusted team.

Safety first. If your CO alarm is sounding or you smell gas, leave your Des Plaines home immediately and call 911. For routine safety, we strongly recommend an annual furnace inspection. During our maintenance visit, we perform a thorough combustion analysis, check the heat exchanger for cracks (a common source of CO leaks), and inspect the venting system. This proactive service is a cornerstone of our honest approach, designed to identify and fix potential risks before they become emergencies.
