Common questions
What to know before you call.
Every home and system is different. These answers give you a useful starting point.
How often should air ducts be cleaned?
There isn't one schedule that fits every home. The right timing depends on the system, visible buildup, recent remodeling, pets, and other household conditions. An inspection can help determine whether cleaning makes sense for your home now.
How long does a duct cleaning take?
Timing varies with the size of the home, the number of vents, system layout, accessibility, and the amount of buildup. We can give you a clearer expectation after learning about your home and inspecting the system.
Why is dryer vent cleaning important?
Lint and other restriction can reduce airflow through the vent, increase drying time, and make the dryer work harder. Cleaning the vent path supports safer, more efficient airflow, but it does not replace proper dryer use or maintenance.
What should I expect during the visit?
We begin by reviewing the service and inspecting the relevant system. After confirming the scope, we complete the cleaning and finish with a walkthrough so you can see what was addressed.
Do I need to prepare my home?
Please make the vents, registers, dryer, and main system areas easy to access when possible. If anything else is needed for your specific visit, we'll let you know beforehand.
