Air duct cleaning and dryer vent cleaning are different services. Air duct cleaning targets the HVAC supply and return ducts that move heated or cooled air. Dryer vent cleaning removes lint from the dryer exhaust path. If drying times are slow or the dryer runs hot, prioritize the dryer vent first for safety.
Do not bundle blindly: price HVAC duct cleaning with the cost calculator, then compare dryer vent pricing separately with the dryer vent cleaning cost guide.
Side-by-side comparison
| Question | Air duct cleaning | Dryer vent cleaning |
|---|---|---|
| System cleaned | HVAC supply ducts, returns, trunks, and sometimes accessible equipment | Dryer transition hose, wall duct, roof or wall termination, and lint path |
| Main purpose | Remove dust, debris, renovation material, pest residue, or contamination | Remove lint that restricts exhaust airflow and increases fire risk |
| Common trigger | Visible debris, odor, post-renovation dust, pests, or confirmed contamination | Long drying times, hot dryer, burning smell, lint outside, or no exterior airflow |
| Quote basis | Home size, vent count, access, duct type, and contamination level | Vent length, roof access, turns, blockage severity, and transition hose condition |
When dryer vent cleaning should come first
- Clothes take more than one cycle to dry.
- The laundry room feels unusually hot or humid.
- The dryer shuts off early or feels hot to the touch.
- You see lint at the exterior termination or no airflow outside.
- You smell heat, scorching, or a burning odor near the dryer.
Dryer vent cleaning has a clearer safety case than routine duct cleaning. Use the dryer vent cleaning guide if the dryer is slow, hot, or vented through a long attic or roof route.
When air duct cleaning is the better fit
Choose air duct cleaning when the HVAC system itself has visible debris, multiple dusty registers, contaminated returns, pest evidence, post-remodel dust, smoke residue, or mold-like growth that has been properly evaluated. The air duct cleaning cost guide explains why whole-home pricing changes with vent count and access.
Bundled quote questions
- Are dryer vent and HVAC duct prices listed separately?
- Will the dryer vent be cleaned from both ends if needed?
- Will HVAC cleaning include returns and trunk lines, not just registers?
- Will before-and-after photos show each system?
- Are sanitizer, deodorizer, or mold claims separate and optional?
If the bundle starts cheap and grows quickly, compare line items in the quote comparison tool and review the scam warning guide before approving extras.
Trying to choose between both services?
Write down the symptom: dust from HVAC vents points one way; slow or hot drying points to the dryer exhaust path.

Is dryer vent cleaning the same as air duct cleaning?
No. Dryer vent cleaning clears lint from the dryer exhaust path. Air duct cleaning removes debris from HVAC supply and return ductwork. They use different access points and solve different problems.
Which service is more urgent?
Dryer vent cleaning is usually more urgent when drying times increase, the dryer feels hot, or lint collects outside. Air duct cleaning is urgency-based only when contamination, debris, mold, pests, or smoke residue is visible.
Can one company do both services?
Many contractors offer both, but the quote should separate the dryer exhaust route from HVAC ducts, list prices separately, and show before-and-after documentation for each system.
