We recommend a professional furnace cleaning every 1 to 2 years, depending on your home or business environment. Homes with pets, smokers, or recent renovations may benefit from more frequent cleanings to maintain optimal air quality and system performance.

Most residential furnace cleanings take 1.5 to 3 hours, depending on the system size and level of buildup. Larger commercial systems or those with extensive ductwork may take longer to ensure a thorough, detailed clean.

Over time, dust, debris, and allergens accumulate inside your furnace and duct system. This buildup can reduce efficiency, strain your equipment, and circulate pollutants throughout your space. A clean furnace helps you save energy, extend system life, and breathe cleaner, healthier air.

Common indicators include:

• Dust buildup around vents or registers

• A burning or musty smell when the heat turns on

• Uneven heating or reduced airflow

• Increased allergy or respiratory symptoms indoors

• Higher energy bills without clear cause

• If you notice any of these, it’s a good time to schedule an inspection.
