A&T HVAC | Expert HVAC Repair in Waukegan, IL

Regular maintenance includes a thorough inspection and cleaning of your furnace's heat exchanger, burners, and flue system—key components where cracks or blockages can lead to dangerous carbon monoxide leaks. Our preventative service ensures these critical safety systems are functioning properly, significantly reducing the risk of CO exposure in your home.

A short-cycling furnace often indicates it's incorrectly sized for your home—either too large or failing. Our installation process begins with a detailed load calculation of your Waukegan home to determine the perfect system size. We then install a properly sized, high-efficiency unit that runs in longer, more efficient cycles, eliminating the short-cycling problem and improving comfort and energy bills.

Short cycling can be caused by several issues, including a dirty flame sensor, a clogged air filter restricting airflow, or a faulty thermostat. Our repair service starts with diagnosing the root cause. Often, a professional cleaning of the sensor or replacing the filter resolves it. If it's a more complex control board or sizing issue, we'll explain the needed repair clearly before proceeding.
