Questions and Answers

How can I tell if my furnace is at risk for a carbon monoxide leak in my North Pekin home?

Common signs include a yellow or flickering burner flame (it should be steady and blue), soot or rust around the furnace, excessive moisture on windows, and a persistent, stale smell. The most important step is to install CO detectors on every level and have your furnace professionally inspected annually by a local expert like Keller Heating & Cooling. We check heat exchangers for cracks, ensure proper venting, and verify safe operation to protect your family.

My HVAC unit outside froze over this winter. Is this an emergency, and what causes it?

A frozen outdoor unit or indoor coil is a serious issue that requires immediate attention. In our Pekin-area climate, this is often caused by restricted airflow (from a dirty filter or blocked vents), low refrigerant levels, or a failing defrost cycle. Running the system while frozen can damage the compressor. Turn the system off and call us. We'll diagnose the root cause—whether it's a simple filter change or a refrigerant leak repair—to prevent recurring freeze-ups and more expensive repairs.

What kind of preventative maintenance can help avoid these common HVAC problems in Illinois?

Our local, bi-annual maintenance plan is the best defense. In the fall, we perform a comprehensive furnace safety check, cleaning components, testing for CO, and ensuring efficient operation before heating season. In the spring, we clean coils, check refrigerant levels, calibrate the thermostat, and verify the defrost cycle on heat pumps to prevent summer strain and winter freeze-ups. This proactive care improves safety, efficiency, and extends the life of your system, saving you money on repairs and energy bills.
