Preventative HVAC Maintenance That Pays Off
As your local HVAC team in Arlington Heights, AON Heating & Cooling makes system care simple and proactive. We maintain all major brands of air conditioners, furnaces, boilers, and ductless systems, and we build each plan around your specific needs—not generic service.
Seasonal Tune-Ups
Each maintenance visit includes a comprehensive checklist tailored to your system type and season. We clean key components, inspect safety controls, check refrigerant or gas pressure, test airflow, and make adjustments to ensure peak performance.
Heating Checkups
Before the cold sets in, we inspect your furnace, boiler, or heat pump to make sure it’s safe and ready. We look for wear and tear, test for carbon monoxide leaks, and verify system controls to avoid breakdowns in the dead of winter.
AC Maintenance
In spring and early summer, we prepare your cooling system for the heat with a full inspection and tune-up. This includes coil cleaning, electrical testing, refrigerant level checks, and ensuring your thermostat is communicating properly.
