Heating & Furnace Maintenance Benefits
Your heating system can last as long as twenty years if regularly maintained by trained professionals. An annual inspection is critical to ensuring a well-functioning, durable furnace. Even a minor problem in the combustion process can pose health and safety hazards. Improperly operating gas/oil connections or faulty burner operation can pump deadly carbon monoxide and/or formaldehyde into your home. Call Level 9 Heating & Cooling, and our certified technicians will perform a complete safety check, cleaning, tuning, and troubleshooting to ensure proper operation.

Keep Your Air Clean with Heating Service in St. Louis and Washington, MO | Heating System Maintenance
In a typical six-room house, up to 40lbs of dust is created annually through regular living. Dirty duct systems may conceal contaminants that trigger serious problems for people with respiratory conditions and allergies. Dirt, mold, mildew, pollen, and even rotting animals can be concealed within the ductwork. When debris is allowed to build up inside the ductwork, it creates a barrier against airflow from the furnace’s air handler. This causes the furnace to work harder and results in components wearing out faster. Regular, professional duct cleaning from Level 9 Heating & Cooling will help prevent repairs and increased energy costs, as well as leading to cleaner indoor air quality.
The most common reason for heater repair is human error. Inadequate maintenance leads to nothing but problems. Through annual service, Level 9 Heating & Cooling can uncover small problems before they become big problems, and make sure your furnace is ready for winter. You don’t want to be stuck shivering, waiting for a replacement part on December 25th. Call us today or contact us online to schedule your furnace maintenance. We work on all makes and models, and we’re always available to answer your heating and cooling needs!
