From time to time, Ducted Air Circulation Systems require a preventative maintenance service to ensure smooth operation. Naturally-occurring dust within your home slowly builds up in the fan, inlets and outlets of the Ducted Air Circulation ™ system, diminishing its performance.

The fan needs to work harder, and the air circulation effect is diminished. Plus, sometimes the dust in the inlet can be aesthetically unpleasant, and the filtered inlet* in the roof cavity can become blocked, especially if moisture is entering the roof from bathrooms, kitchens or laundries .sylvania automotive headlight restoration kit review * which you may or may not have depending on which modules were installed or available at the time.air purifier chlorine smell To ensure that dust does not clog and unbalance the fan assembly (which can cause uneven wear on the bearings), it is thoroughly cleaned to prolong its life and to minimise vibrations and noise. oreck hepa air purifier with timer

Additionally, duct can accumulate in the air inlet and diffusers, and moths can become stuck in the filtered inlet leading from the outside ventilation duct (if applicable). The standard Preventative Maintenance cost for a Ducted Air Circulation System includes: Cleaning of ceiling inlet and outlets Removal, cleaning and reinstatement of fan to remove excess dust. Check outlet air flow balancing Check ducting system integrity (connections, vermin damage, accidental alteration of ducting flow path etc) Check & clean eave/gable or roof cowl condensation module fly mesh and inlet.If required (and with your consent), this will be replaced at an additional charge. How often do I need to service the system? General service every year, filter change every 2 years Pictured at right: New filter sock on left (20% larger surface area than older models for enhanced performance) and recently replaced clogged-up filter sock on right. The filter socks are used with the Roof Heat Recovery Module, as well as with some Condensation Control Modules.

If your Ducted Air Circulation System is 24 months old, then it is recommended to have an annual service. If your Ducted Air Circulation System is over 24 months old, then it probably requires a filter sock replacement. Sometimes our servicing staff recommend that the filter sock be changed earlier if it is looking particularly clogged. This depends on the air quality of your roof cavity.When summer temperatures rise and individuals in a building begin to complain about musty smells, the culprit might be the building’s HVAC system if there is mold within the ductwork. As the air in the building circulates, it could blow mold spores onto documents and affect the health of the individuals inside. By knowing how mold infiltrates an HVAC system, you can act quickly to remedy the problem and prevent mold on documents. Mold is a type of fungus that thrives in humid conditions. It feeds on organic materials, from fallen leaves to the oil your fingers leave on a surface. Most types of mold spores are harmless to humans.

However, there are a handful that release harmful mycotoxins that trigger allergies and asthma symptoms and cause serious health problems. When conditions are optimal and molds grow on property, they become destructive. On documents, for example, molds discolor and stain pages, damage paper fibers and release a musty smell. Signs of Mold in a Cooling System Musty smell: Rooms acquire the telltale odor, particularly when the A/C blows New mold growth: If you’ve taken strict measures to prevent mold on documents and in your building, but notice mold growth, spores might live in the ductwork Allergies: Individuals complaining of allergy symptoms during the warmer months could point to a mold problem in an HVAC system Ductwork leaks: When there’s a leak in the ductwork, the HVAC system will pull air from the areas surrounding the ducts. Ductwork leaks will cause uneven heating and cooling in a building, make some rooms feel more humid than others, and produce a musty smell.

A professional ductwork inspection and repair will help reduce the amount of mold that circulates in a building. Dirty ducts: With time, ducts accumulate lint, dirt, dust and mold. Signs that ducts need cleaning include excessive dust levels, uneven temperatures and musty smells. Hire a professional ductwork cleaning service every few years to clean and inspect the ducts. Dirty air filter: When an air conditioning filter is dirty, the cooling system won’t circulate air as effectively. It will also be less effective at cleaning the air that enters a building. Change the system’s filter as often as the manufacturer recommends. A/C fan: When an air conditioning fan is set to the “On” position, the fan continuously runs. Incidentally, the moisture that condensed on the evaporator coil re-evaporates and the fan blows it into the building. This increases relative humidity levels in a building, which promotes mold growth. To remedy the problem, set the fan to the “Auto” position.

A/C size: An air conditioner that’s too big for a building doesn’t dehumidify the air well because the system doesn’t remove the moisture in the air at full capacity for the first few minutes of operation. The shorter the air conditioner cycle, the less effective the unit is at removing moisture. The best way to remedy this is to replace the A/C unit with one that’s the correct size. Closed doors: Unless each room in a building has its own fully ducted return air system or its own return air transfer pathway, leave the interior doors in the building open. Otherwise, depressurization might lead to moisture problems and increased mold activity. Humid conditions: If you’re located in a humid area, an air conditioner might not be enough to control the humidity in a building. Adding a dehumidification system or a dehumidifier to rooms that store documents could deter mold growth.
