With ARCO Heating & Cooling’s seasonal maintenance services, homeowners in Missouri and   Illinois can enjoy peace of mind knowing their systems are ready for anything.


Why Fall Maintenance Matters


Your HVAC system has worked hard all summer, and fall is the ideal season for preparing and addressing any wear and tear. Routine maintenance improves performance, extends the life of your equipment, and can prevent costly breakdowns during the coldest days of winter.

Fall HVAC Maintenance Checklist

Here’s a quick checklist to help prepare your HVAC system:


1. Replace Air Filters

Clogged filters restrict airflow and force your system to work harder. Swap them out for clean ones to maintain efficiency and indoor air quality.


2. Inspect and Clean Vents

Blocked or dirty vents reduce circulation. Make sure all registers are unobstructed and clean to ensure warm air can flow freely.


3. Check the Thermostat

Make sure your thermostat is working properly and consider upgrading to a programmable or smart model for better energy control.


4. Test the Heating System

Run your heater before temperatures drop too low. Strange noises or a lack of warm air could indicate underlying issues that need attention.


5. Schedule Professional Inspection

An expert technician can check for potential problems, clean internal components, and make sure everything is functioning safely and efficiently.
