Dryer Vent Cleaning: The Fire-Safety Service Most Homes Skip (Calgary Guide)
Your dryer isn’t supposed to heat your house — but in many Calgary homes, it’s doing exactly that.
Lint buildup inside dryer vents is one of the most overlooked fire hazards in Canada. It restricts airflow, makes your dryer run hotter, and can spark fires without warning.
In this guide, we’ll cover why dryer vent cleaning matters, how often to schedule it, and what signs mean you’re overdue. It’s quick, affordable, and one of the smartest home safety steps you can take.
TL;DR
Yes, you should clean the dryer vent. Lint + heat = fire risk and sky-high dry times.
When? Do a quick check every season; plan a pro clean about once a year, sooner with big families/pets/long runs/roof exits.
Bundle it with duct cleaning or a furnace tune-up to save a truck roll.
Why it matters (and what it fixes)
Safety
Lint is ultra-flammable; blocked vents overheat dryers.
Performance
Clear vents = shorter dry times, lower power/gas use, less wear on clothes.
Moisture control
A plugged vent pumps humid air into the home—hello, foggy windows and musty laundry rooms.
Signs you need dryer-vent cleaning (today)
  • Loads that used to take 40–50 minutes now take forever.
  • Laundry room feels hot or humid; dryer or clothes are very hot to the touch.
  • Lint gathering around the door seal or behind/under the dryer.
  • Outside hood flap barely opens (weak exhaust) or is packed with lint/bird fluff.
  • Burning or musty smell during cycles.
How often should Calgary homes clean the dryer vent?
Annual for most households
Standard recommendation for typical family usage
Every 6 months if:
  • Multiple loads daily
  • Pets
  • Long vent runs
  • Roof terminations
  • Older foil/accordion flex
After renovations or if you've moved into a new place with an unknown history—do it once now and set the baseline.
DIY vs. Pro (be honest about the run)
DIY (5–15 minutes you can do now):
  1. Remove and vacuum the lint trap & cavity.
  1. Pull the dryer forward, unplug (and shut off gas if gas dryer), gently detach the transition duct.
  1. Vacuum the transition duct and wall stub; re-attach without crushing/kinking.
  1. Go outside: make sure the hood opens freely and isn't lint-caked or bird-blocked.
Call a pro when:
Vent runs are long, have multiple elbows, or terminate on the roof.
You see foil/plastic accordion ducting (swap to rigid or semi-rigid metal).
You smell burning, have carbon-monoxide concerns (gas dryer), or the dryer is throwing error codes.
You want the whole path mechanically cleaned: from dryer outlet → transition → inwall/ceiling run → exterior hood.
What a proper professional clean includes
01
Airflow test before/after
02
Disconnection at the dryer, cleaning the transition duct (or replacing it if unsafe)
03
Mechanical brushing/air whip through the full vent run, with vacuum capture
04
Clearing the exterior hood (and advising on bird guards)
05
Reassembly with metal foil tape or clamps (no screws poking into the airstream), then a final airflow test
Quick upgrades that make a big difference
  • Use rigid or semi-rigid metal for the transition; avoid plastic/accordion flex.
  • Keep the run short and straight; every tight bend is a lint magnet.
  • Outside hood: no mesh screens (they clog); a proper dryer flap or listed guard only.
  • If your run is very long, ask a pro before adding a booster fan (needs the correct, listed type and proper placement).
Special Calgary note: roof terminations
Roof exits collect lint and snow, and they're harder to reach. If yours terminates on the roof, lean toward twice-yearly checks and let a pro handle the cleaning and safety.
FAQs & Smart Bundles
My dryer still takes forever after cleaning—now what?
Check the lint trap screen (some get coated by fabric-softener residue), verify gas flame cycles normally (gas dryers), and make sure the drum seals and blower are healthy. Sometimes the culprit is the dryer, not the vent.
Can I use those "cleaning rods" from the hardware store?
They're fine for short, straight runs. For long/roof runs, a pro's rotary brush + high-CFM vacuum is safer and more effective.
Smart bundles (save a truck roll)
  • Dryer-vent cleaning + duct cleaning (same visit).
  • Dryer-vent cleaning + furnace tune-up (tech checks airflow, static pressure, and filter at the same time).
  • Add HRV/ERV clean if your fresh-air hood is lint-y or you've got moisture issues.

Safety: If you smell gas or burning, turn equipment off and call emergency services immediately.
