Can duct cleaning be done in winter?

As business owners and facility managers, ensuring employees’ and customers’ safety, health, and comfort is a top priority. A clean and efficient HVAC system is crucial to achieving this goal, and regular duct cleaning is a vital aspect of maintenance. Dirty ducts can lead to a range of problems, including poor indoor air quality, reduced energy efficiency, and health issues.

To ensure the air quality in your building is safe and hygienic, it’s essential to have your ducts professionally cleaned. But when is the best time of year to do this, and can duct cleaning be done in winter? While some HVAC contractors suggest that duct cleaning should only be carried out in spring or summer, the truth is that there are benefits to having your system professionally cleaned year-round.

Why duct cleaning is important in winter

As the temperatures drop, businesses rely more heavily on their heating systems to maintain a comfortable indoor temperature. With the HVAC system being used more frequently, any contaminants in the ductwork are circulated more regularly around the property and can cause health issues such as allergies, respiratory problems and headaches. Regular duct cleaning can remove these contaminants and promote clean airflow throughout the building.

Advantages of winter duct cleaning

Winter duct cleaning offers several advantages that are unique to the season, including:

Improved air quality

By cleaning the ducts over the winter months, you can ensure that the indoor air quality is at its best during a time when people tend to spend more time indoors. Doing so can help to reduce the spread of illnesses and improve overall health and well-being.

Reduced utility costs

Clean ducts can improve the energy efficiency of your HVAC system, which can lead to significant reductions in utility costs.

Increased safety

During winter, businesses may need to use electric heaters as a supplementary source of warmth, which can be dangerous if not operated correctly. Regular duct cleaning helps to reduce the risk of fire hazards by removing any flammable residue, such as dust or lint, from the system.

Improved performance

Dirty ductwork can restrict air flow, reducing the performance of your HVAC system and causing it to work harder than necessary. By removing any debris and contaminants from the ducts, your system doesn’t have to work as hard to circulate air, reducing wear and tear on the equipment and extending its lifespan.

Factors affecting duct cleaning in winter

Temperature and humidity can affect duct cleaning in winter. Extremely low temperatures can cause issues with cleaning equipment and make it difficult for technicians to work efficiently. In addition, high humidity levels can make removing debris and contaminants from the ductwork challenging. To ensure the best results, try to schedule duct cleaning during a milder weather window when the temperature is above freezing, and the humidity is low.

How to prepare for winter duct cleaning

Preparing for winter duct cleaning is crucial to ensure a safe and efficient cleaning process. Snow, ice, and sleet can make winter duct cleaning challenging, as they can hinder access to the outdoor unit and the ductwork. To ensure the cleaning process goes smoothly, it may be necessary to clear any snow or ice from the outdoor unit and the surrounding area to provide clear access to the ductwork.

Always work with a professional duct cleaning service with experience working in winter conditions and who can provide guidance on the best approach for your specific situation.

Recommended schedule for seasonal duct cleaning

To determine the appropriate schedule for duct cleaning, it’s important to consider factors such as the age of your HVAC system, the level of usage, and the type of industry you work in. The best approach is to work with a professional duct cleaning service to develop a customised cleaning plan designed specifically for your property.

Generally speaking, however, it’s recommended to perform duct cleaning at least once a year for buildings with normal usage and twice per year for facilities with high traffic. During winter, try to schedule the cleaning as early in the season as possible to maximise the benefits of improved air quality and energy efficiency.


Overall, winter duct cleaning can provide significant benefits to your business, including improving indoor air quality, reducing utility costs, increasing safety and extending the lifespan of your HVAC system. With careful preparation and an experienced professional on your side, you can ensure that the process goes smoothly and that your business is equipped to handle the coldest months of the year.
