Duct cleaning for Healthier Fresher Air

Most home owners are well aware that heating and cooling system should be inspected annually. This is best done before the fall or winter rush. But making sure the furnace is up to snuff is not all one should do. Getting your home's air ducts cleaned is also a crucial step in ensuring that your family is living in a healthy, fresh air indoor environment.

If you have pets or notice a dusty or unpleasant odor when your furnace comes on, it is advisable to consider getting your ducts professionally cleaned.

The most effective way to clean air ducts and ventilation system is by having the contractor place the system under negative pressure through the use of a specialized truck-mounted vacuum.

How often should they be cleaned? The answer is that it depends on the individual household, under normal circumstances every two to three years is advised. However, if there are any allergies in the family or you have pets you may want to consider having the ducts serviced more often. A comprehensive cleaning of all heating and cooling system components (furnace fan blower, furnace heat exchange, air conditioning coil, humidifier, ducts, etc.) will also help air circulation.

If you have recently had or are having your furnace upgraded to a more efficient heating system, you should have your heating ducts cleaned. During any type of home renovation there may be a lot of dust from drywall, plaster or wood cutting projects and again a cleaning would be advisable.

Be sure to allot three to four hours of time for the duct cleaners to do the job. Mention any other items that could require cleaning as well, such as your air conditioner coil, or dryer vent. Now that the ducts have been cleaned, maintaining cleaner indoor air can be attained by using full-time air purification equipment such as an HRV (Heat Recovery Ventilator) or high-efficiency air filtration (hybrid systems).


An HRV allows fresh air to enter while exhausting an equal amount of stale air and recovering the heat or cool from the exhaust side and using it to warm or cool fresher air coming in. Air is filtered before being redistributed in the house. Also now available are Energy Recovery Ventilators (ERV’s), which return not only heat energy, but moisture to help humidify the home if required. If you suffer from allergies or asthma you can add a HEPA (hybrid) filtration system to the HRV and have fresh, clean air.

When you are having your ducts cleaned it is also a good idea to have your dryer venting cleaned as well. By maintaining clean dryer venting you reduce the risk of fire, save money on energy costs and prolong the life of your dryer.

Good air quality in your home is something that will not only make you feel good, but will also make your home environment comfortable for family members with allergies and sensitivities to dust or other airborne particles.
