Research by the U.S. Environmental Protection Agency (EPA) has demonstrated that HVAC system cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical operate components. Clean, efficient systems are less likely to break down, have a longer life span, and generally more effectively than dirty systems.

We employ the source removal method of cleaning. This process is the highest standard in the industry and is the only method endorsed by the National Air Duct Cleaners Association (NADCA). It requires placing the system under continuous negative pressure, through the use of a specialized, powerful vacuum. While the vacuum draws air through the system, special devices are inserted into the ducts to dislodge any debris that might be stuck to interior surfaces. The debris can then travel down the ducts to the vacuum, which removes it from the system and the home.

Make sure there is unrestricted access to the furnace, each room vent, and that furniture is not blocking the vents.

The amount of time it takes to clean a residential air duct system depends on many variables such as the size of the home, the number of systems and the extent of the contamination. A complete cleaning can take between 2 and 3 hours on an average sized home. Larger homes take longer or if the set-up of the equipment is difficult, however we are in your home until the job is completely finished. Any company that cleans your home in a short period of time is probably not doing a proper job.

Duct cleaning services range in cost. At Encore, we offer straightforward pricing so you know the price before any work is done. There are no surprises or hidden extra charges. We provide free, no-obligation estimates for residential duct cleaning over the phone after a few questions. The cost is determined by the size of the house and the type of service you require. For small commercial buildings, it is normally required for us to visit the site first to provide a free, no-obligation written estimate.

We accept cash, cheques, Visa and MasterCard and e-transfer.

You can determine if the air duct system cleaning was effective by inspecting the system before and after cleaning with our camera inspection system. We can also show you some of the debris as it is being removed.

We recommend having your system cleaned every 1-2 years. Frequency of cleaning depends on several factors. Some of the things that may lead a home owner to consider more frequent cleaning include:

  • Smokers in the household
  • Any kinds of pets in the house
  • Water contamination or damage to the home or HVAC system
  • Residents with allergies or asthma who might benefit from a reduction in the amount of indoor air pollutants in the home’s HVAC system
  • After home renovations or remodelling
  • Prior to occupancy of a new home
  • Carpets in the home or popcorn ceiling
  • If you live near an airport or a busy road
  • More than two people live in the house

Not all air duct cleaning companies are the same. Beware of discount or blow-and-go duct cleaning companies that advertise very low prices, if it sounds too good to be true, then it is. Don’t get scammed by no quality low price jobs it’s a waste of your money. Some use harsh chemicals which could potentially make the indoor air quality much worse.

When choosing an air duct cleaner, avoid making your decision solely on the basis of price. The quality of the job should be your highest priority because quality will determine your savings in energy costs, comfort and durability. At Encore, we provide the total cost and scope of the job before the work begins. We are insured and bonded for your peace of mind.
