Why there is no flat number printed here
A single-story house with the dryer against an outside wall and a six-foot run is a different job from a two-story with the laundry upstairs and a cap on the roof. Same service, different work, and a page quoting one figure for both is quoting the wrong one to somebody.
The number you want is the one for your duct, and that takes about a minute on the phone. What this page can do is tell you exactly what we are asking about and why, so the quote is not a black box.
The six things that move the price
How long the run is. The distance from the back of the dryer to the outside. Short runs are quick. A run crossing the house takes longer to brush and longer to verify.
Where it comes out. A wall hood at ground level is the straightforward case. A roof cap means working from the roof, which is a ladder, more setup and more time.
How many bends are in it. Turns slow the brush down and are where lint collects, so a run with several elbows takes more passes than a straight one of the same length.
What is actually in there. Lint is routine. A bird nest, a rodent nest or a collapsed section is a different job, and you hear about it before it starts rather than on the invoice.
How many vents. A second dryer, a second unit, or a building with a stack of them is priced per vent, and multiple vents on one visit cost less each than separate trips.
Whether anything needs replacing. A crushed transition hose or a hood whose flap has given up are parts, not cleaning. Small money, quoted separately, and never done without you saying so.
What a quote should cover
Ours covers the whole run, both ends, and proof. The dryer gets pulled out, the transition hose comes off and is cleaned separately, a rotating brush runs the full length of the duct with a vacuum holding suction at the source, the hood or cap gets checked for a flap that opens, and airflow is measured before and after.
You get both readings and photos of what came out. That is the part worth asking any company about, because a vacuum held at the wall for ten minutes and a full brush of the run produce very different results and can carry the same name on an invoice.
No trip charge and no diagnostic fee. If we get there and the duct is genuinely fine, you hear that.
The three ways a cheap advertised rate stops being cheap
The roof surcharge discovered on the day. The advertised price is for a ground-floor wall vent, and the crew arrives to an upstairs laundry room. This is the most common one in the valley, because so much of Henderson and Summerlin is built that way.
The second vent that was not in the price. Fine if you knew. Worth asking when a number sounds low.
The upsell to air duct cleaning. Air ducts are a real service and a separate job, and most homes do not need them touched. The air duct page says plainly when it is worth doing, which for a lot of houses is not now.
Ask for the price with your actual vent described, not the headline. Any company worth calling will give you one.
What you are buying
A dryer fighting a blocked duct runs two cycles for one load. That is the power bill for every load until it is fixed, plus wear on a machine running twice as long as it was designed to. The arithmetic depends on your rates and how much laundry you do, and we are not going to invent a figure for your house.
The other half is the lint sitting against a heat source, which is the reason the job exists at all and does not need a number attached to be worth an hour.
What to have ready when you call
Where the laundry room is, whether the vent comes out of a wall or the roof, roughly how far the dryer is from the outside, and what the dryer is doing now. Four answers, and they are enough for a firm price.
If you do not know where the vent exits, say so. It is a common answer and it is not a problem.
