Your Essential Fall HVAC Maintenance Checklist for St. Louis

Schedule a Professional Furnace Tune-Up
The most critical step in fall heating prep is a professional furnace tune-up in St. Louis. Our certified technicians inspect all components, clean the system, and ensure it operates safely and efficiently. This preventative service not only enhances performance but also extends the lifespan of your unit, providing you with essential peace of mind.

Inspect and Replace Your Air Filter
A clogged filter is a common cause of furnace issues, restricting airflow and forcing your system to work harder. We recommend checking your filter monthly and replacing it if it’s dirty. This simple task improves indoor air quality, lowers your energy bills, and helps prevent costly repairs during the coldest months of the year.

Clear the Area Around Your Furnace
For safety and proper performance, your furnace needs adequate space for air circulation. Before the heating season begins, we advise clearing away any boxes, storage items, or debris from the immediate vicinity. Ensure vents and registers throughout your home are also unblocked by furniture or rugs to allow for unobstructed airflow.

Test Your Thermostat and Carbon Monoxide Detectors
A faulty thermostat can lead to heating inconsistencies and wasted energy. We suggest testing it by switching it to “heat” to ensure it properly communicates with your furnace. This is also the perfect time to test your carbon monoxide detectors and replace the batteries, a crucial safety check before you start using your heating system.
