  • Why should I have my ducts cleaned?

    Spring cleaning and preparation for winter often involves washing floors, organizing closets, and other household chores. Cleaning your ductwork and dryer vents should also be on the “to-do” list. While these two areas are often overlooked, they can greatly impact home and work life. An unclean duct system may contain harmful bacteria, germs, dust mites, mold and mildew. It is imperative to clean ducts after a home renovation or addition. Cleaning can boost furnace and air conditioning efficiency and save you money.

  • What’s involved in the duct cleaning process?

    Dr. Duct is proud to use the best equipment available. We use truck vacuum compressed air, CCTV cameras for inspection, and employ extendable power units for direct contact cleaning. We also clean out the blower fan, the heat exchanger, and the evaporator coil. Your entire system will be cleaned, including vents, piping, liners, ductwork, drop boxes, and the air handling unit.

  • How long does duct cleaning take?

    An average job takes approximately 2.5 to 3 hours to complete, using a team of two technicians. Various unforeseen factors can impact time (e.g. finished / unfinished basement, newer / versus older house, never cleaned or improper previous duct cleaning, etc.).

  • How often should I get my ducts cleaned?

    Typically, a duct cleaning service will last five to seven years. Renovations, family pets, the number of occupants in a property, time spent out of the home during winter months, allergies and asthma all affect the longevity of the duct cleaning service.

  • Will duct cleaning reduce my energy bill?

    Systems that have never been cleaned or lack proper care do not run efficiently. Save on your heating and cooling bills by cleaning and maintaining your air handling system. It will have a longer life span, be less likely to break down, and run more quietly.

  • Why do we need disinfectant in the duct system?

    Disinfectant is a product we apply to the interior surface of the duct system. It will eliminate bacteria, germs, dust mites, fungus, mold, mildew and other microscopic particles. By applying disinfectant, the positive effects of duct cleaning can last an additional 2 to 3 years. We use a natural product that both kills bacteria and adds a light, refreshing scent throughout your home.

  • Are there hazards associated with duct cleaning?

    There are absolutely no hazards when you have qualified technicians cleaning your ducts. We use naturally-based disinfectants and enzymes with compressed air and strong vacuum suction.

  • How do I know the duct cleaning was performed correctly?

    Once your duct cleaning is complete, the furnace fan system can be turned on. You shouldn’t hear any noise from residue left behind. A new high performance furnace filter is installed and, after two weeks, should remain clean and white. A brown or black filter indicates that it needs to be replaced and your system is dirty.

  • Why should I get my dryer vent cleaned?

    Not cleaning your dryer vent can cause serious damage to your dryer and your home. Consistent flow is necessary behind the back of the dryer and throughout the ducting that connects to the outside vent. Blockage reduces the dryer’s performance. Your clothes will take longer to dry, the dryer will use more energy, and the added heat and effort negatively affect the lifespan of the dryer. Dirty and blocked vents can also cause dangerous fires.

  • How often should I have my dryer vent cleaned?

    Depending upon setup and usage, the dryer vent should be cleaned every two to four years. Homeowners can perform a visual inspection to check for blockage at the dryer vent exhaust. If the top of the dryer feels extremely warm to the touch, a blockage may be causing hot air backflow into the dryer.

The guys arrived on time and did an excellent job. They invited us to watch the monitor as they were cleaning the ductwork. Very professional. Will hire them again.
Don
I highly recommend Dr. Duct. I shopped around and they gave the best estimate. They arrived as scheduled, did a great job, cleaned up and the price was as originally quoted. They were extremely professional and cheerful.
Carole
Third time that I have used Dr. Duct. I am very happy with the results. Excellent service. Great team of workers.
Lynne
I had great experience with these guys. Came on time, put a lot of effort and attention to detail. Their price was 30% cheaper than their competitors (they had a promo at that time). As it turned out a lot of the HVAC companies in Ottawa re-sell third party duct cleaning services..
Dan
The guys were very professional, great job, I was even able to watch it all on the screen. That was a eye opener. Would definitely recommend them.
Bonnie
I am well pleased with the services I received with Dr. Duct. These guys did a great job replacing my dryer piping and repairing a rattling air duct. Very reasonable prices too.
