How Often Should You Clean Your Furnace and Ducts for Optimal Efficiency and Air Quality

We Maintaining your furnace and ducts is essential for optimal efficiency and air quality. The National Air Duct Cleaners Association (NADCA) recommends cleaning air ducts every three to five years, but this can vary depending on the environment. For instance, food manufacturers and manufacturing operations that create combustible dust risks require more frequent cleaning. Domestic smokers, pets that shed hair, and people with allergies may also need to increase the frequency of cleaning.

It is not necessary to clean the ducts if there is a small amount of dust, hair, and other debris, but if there is visible mold, an infestation, or an excessive amount of dust and dirt coming out of the ventilation grilles, it is best to clean the ducts. Midwest duct cleaning specialists and other HVAC system cleaning specialists provide an inspection of the air conditioning system and provide recommendations for cleaning. While regular cleaning of HVAC systems is not necessary to maintain health and air quality in the home, it is important to check ventilation grilles regularly and clean ducts if excessive amounts of debris enter the house through ventilation grilles. If there is visible mold growth inside your air conditioning system, it's time to call an air conditioning company to clean the vents before mold and mildew spores spread throughout the rest of the house. In conclusion, it is recommended to schedule furnace maintenance every 1 to 2 years (ideally once a year) and to clean the ducts at intervals of 3 to 5 years for the system to operate optimally and for excellent indoor air quality.

Minimize machine downtime and maintain a clean and safe environment for your employees with an HVAC system cleaning partner backed by a track record based on hard work, integrity and a commitment to excellent service.
