Adair Heating Cooling & Electric: Professional HVAC Services Serving Macomb, IL 61455

Key warning 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. If you experience headaches, dizziness, or nausea at home that improve when you leave, it's a medical emergency—leave immediately and call 911. For safety, we recommend annual professional furnace maintenance and installing CO detectors on every level of your home.

Not necessarily. Often, thermostat malfunctions are isolated issues. We'll first diagnose if it's a simple thermostat replacement, a wiring problem, or a sign of a larger system fault. For older systems (15+ years), persistent control issues alongside high energy bills or frequent repairs may indicate it's time for a replacement. We provide honest assessments and will only recommend a new HVAC installation if it's the most cost-effective and reliable solution for your Macomb home.

Our seasonal maintenance checks are proactive. We clean critical components, check for gas leaks and heat exchanger cracks (a source of carbon monoxide), calibrate your thermostat, and ensure proper airflow. This prevents small issues from becoming costly, unsafe emergencies, especially during extreme Illinois weather. Regular servicing also improves efficiency, lowers utility bills, and extends the life of your system, giving you peace of mind.
