The efficient operation of a heat recovery ventilation system directly depends on regular maintenance and professional cleaning.

Modern heat recovery ventilation (HRV) systems provide a continuous supply of fresh air in residential, commercial, and institutional buildings. Over time, dust, microorganisms, mould, and other contaminants accumulate inside air ducts, ventilation systems, and equipment. This contamination can reduce system efficiency and negatively affect indoor air quality.

A poorly maintained heat recovery ventilation (HRV) system gradually loses efficiency, increases energy consumption, and fails to maintain optimal indoor air quality. Contaminated air ducts increase the load on fans, reduce equipment lifespan, and increase operating costs.

Dirty heat recovery units can have a negative impact on health

Air quality: Dirty or contaminated heat recovery ventilation (HRV) systems can circulate dust, mould and other airborne contaminants that may affect indoor air quality and occupant health. Poor indoor air quality can contribute to fatigue, allergies, respiratory conditions, headaches and other long-term health problems. Homes with pets are particularly prone to increased contamination, as pet hair and dander can accumulate within the ventilation system. Without regular maintenance, bacteria, mould, fungi and even pests may develop inside the system.

System efficiency: A contaminated system loses efficiency and may consume more electricity. In commercial premises, food service establishments, and other facilities, a poorly maintained heat recovery system can also lead to unpleasant odours that cannot be eliminated with air fresheners or fragrances.

Longevity: Properly maintained and professionally serviced heat recovery ventilation (HRV) systems have a longer lifespan and require fewer repairs. Poorly maintained systems can also cause dark staining on ceilings and around air diffusers or ventilation grilles.

Regular maintenance of ventilation systems is particularly important in schools, kindergartens, healthcare facilities, offices, manufacturing facilities, and apartment buildings, where large volumes of air circulate every day..
