SHOULD YOU GET YOUR HEATING DUCTS CLEANED ?

ALL ABOUT DUCTED HEATING SERVICING

REPAIR Heating & Cooling does not provide duct cleaning service.

Over years of experience we’ve noticed that regular duct cleaning is unnecessary for most householders and, in some instances, can cause more harm than good.

There are examples of ducts that have become badly contaminated with a variety of materials that may pose risks to your health. The duct system can serve as a means to distribute these contaminants throughout a home. In these cases, duct cleaning may make sense.

However, a light amount of household dust in your air ducts is normal. In fact, as you walk around in your house you raise a small cloud of dust particles wherever you go. Dust will be present in one form or another whether you have clean ducts or not.

Duct cleaning is not considered to be a necessary part of regular maintenance of your heating or cooling system.

Some duct cleaning equipment might result damage to your air duct system.

Instead of having duct cleaning done, we recommend fitting a new Filtered Return Air Grill, to stop dust from entering into the system. In the future you will need to clean filter only, not entire ductwork.

Price for a New Return Air Grill starts from just $120 incl GST.
