Duct Cleaning Port Moody

Ducts run behind walls, under floors and through attics, so nobody sees what is inside them until a register comes off. If you typed “duct cleaning” into a search bar, you probably want to know whether yours deserve attention and what the work would actually look like. The answers below are written for households around Port Moody and explain ductwork cleaning in everyday language, from the first warning signs to what happens after the crew packs up.

What is the difference between supply and return vents?

Return ducts carry room air back to the blower, passing through the filter on the way, and supply ducts carry it out again to each register, so together they form one loop that collects dust as a single system. A return is usually the bigger grille with fixed slats; a supply register tends to be smaller, with a lever or louvers you can adjust. On the job, the return side is often the dirtier half, since it sees room air before anything filters it. Pet hair, lint and fine dust gather near the grille and along the first section of duct, while supply runs hold lighter dust. Cleaning one half without the other leaves the job unfinished.

What happens to the grilles on your air ducts during cleaning?

Vent covers and registers are usually taken off, washed and dried, then put back once the ducts behind them are done. You can do the same between cleanings. Unscrew wall and ceiling grilles, lift floor registers out and wash them in warm soapy water in a sink or tub, using a soft brush on the slats. Dry them fully before refitting so steel covers do not rust. While a cover is off, vacuum the first few inches of the opening with a hose attachment. Avoid bending the adjustable louvers on supply registers, since they direct the air into the room.

Are sprays or coatings needed inside your air ducts?

Routine duct cleaning is a mechanical job done with brushes, air and suction, and it does not require chemicals. Some companies offer sprays, deodorizers or coatings as add-ons. If one is suggested, ask what the product is, why your particular system needs it and how it will be applied, and ask to see the label directions. A spray is no substitute for removing debris or fixing a moisture problem. If anyone in your home is sensitive to scents or chemicals, mention it before the visit, and feel free to decline anything you are not comfortable with.

Why do quotes for ductwork cleaning vary so much?

System size and access decide most of what duct cleaning costs. A larger home usually has more registers and grilles to open, and a second furnace or air handler means a second system to clean. Location counts as well: ducts in an attic or crawlspace take more effort than those in an open basement, and heavy buildup needs extra passes. Add-ons such as coil cleaning, a dryer vent or access repairs are usually priced separately. A quote in writing, with every included item named, puts competing offers on equal terms.

What should you tell a company when booking duct cleaning?

Tell us how many systems the house has, where they sit and roughly how many vents there are; those are the first items on our phone checklist. We also ask whether the ducts are metal, flexible or a mix, if you know, and whether anything has happened recently, such as a remodel, a flood, a new pet or signs of mice. Those answers decide which collection unit we bring, how long to plan for and whether two technicians are needed. A homeowner who counted the registers beforehand usually gets a quote that stays the same once we arrive.

Should ducts be cleaned when a furnace or air conditioner is replaced?

It is a good moment to consider it. Installing new equipment means cutting and refitting plenums and duct connections, which leaves metal shavings, dust and scraps near the unit. Meanwhile, the existing ducts still hold whatever built up over the life of the old system. Cleaning them before or right after the new unit goes in means its blower and coil start with a clean path. Ask the installer how they will protect the ducts during the swap, and schedule the “duct cleaning” visit so it does not clash with their work.

Should you clean your air ducts yourself or hire a professional?

You can handle the surface part yourself, but a household vacuum cannot clean the ducts properly. Safe DIY tasks include washing vent covers, vacuuming the first few inches behind each register, wiping return grilles and changing the filter on schedule. Beyond arm’s length, a shop vacuum lacks the suction to pull debris from long runs, and pushing brushes in blindly can loosen dust without removing it or tear flexible duct. A professional cleaning applies strong suction across the whole system at once. Leave the furnace or air handler cabinet closed, especially on gas equipment.

How soon can you run the heating or cooling after the ducts are cleaned?

Usually as soon as the crew has finished and the system is put back together. Before leaving, the technicians should refit every register, close any access openings they made, reinstall or replace the filter and switch the system on to confirm air is moving normally at the vents. A small puff of loosened dust when the blower first starts can happen and settles quickly. If the crew applied any product inside the ducts, ask how long to wait, since that is the one case where a delay may be recommended. When you book “duct cleaning”, ask whether the crew will run the system with you before it goes, so you know it is ready to use.

How do you spot a duct cleaning offer that is too good to be true?

The red flags we hear about most are bait pricing, rushed vacuuming and borrowed photos. A homeowner books an advertised special that covers a handful of vents, and the bill triples at the door. A crew runs a shop vacuum into each register for twenty minutes and leaves. Someone shows a picture of dark debris that never came from that house. Protecting yourself is simple: ask how the system will be put under suction, whether returns and trunks are included, how access ports are sealed and whether you can watch or see photos as the work happens.
