With AZ Dryer Pros, a new or replacement dryer vent installation in Arizona starts at $399. The technician looks at where the dryer sits, plans the route to the outside, and gives you the exact price before any work starts. The price depends mostly on the length of the run and whether it goes through a wall, attic or roof. If you decide not to go ahead, you only pay for what you approved.
When you need a new dryer vent
- A laundry room being added or moved
- A new dryer that sits in a different spot than the old one
- An old vent made of plastic, vinyl or foil inside the wall
- A duct that has been crushed or patched too many times to trust
- A vent that ends in the attic or garage instead of outside
- A remodel that closed off the old route
How long can a dryer vent be?
Under the International Residential Code (M1502.4.5.1), a standard dryer exhaust duct can be up to 35 feet, measured from where the transition hose connects to the outlet. Every sharp 4-inch 90° elbow counts as 5 feet and every 45° as 2½ feet. So 20 feet of straight duct with three 90° turns already adds up to 35. The dryer manufacturer's instructions take precedence, and some allow a longer run. When a run goes past 35 feet that way, the code requires a permanent label near the dryer connection showing its length.
What we install
Inside walls, floors and attics we use 4-inch rigid metal duct. Joints are fitted with the inside end pointing with the airflow and sealed with foil tape, without screws that reach into the duct. The run is supported so it doesn't sag. Outside, it ends in a hood with a flap that closes when the dryer is off. We don't put fine screens over dryer outlets, because they catch lint and clog.
Tight laundry closets: the in-wall vent box
In many Arizona condos and newer homes the laundry is in a narrow closet, and the hose behind the dryer gets crushed every time the dryer is pushed back. A recessed dryer vent box sits inside the wall so the connection is set back and the hose has room. We can add one as part of a new install or a reroute, priced on your quote.
Wall, attic or roof
A short run straight out an exterior stucco wall is the best case. When the laundry is in the middle of the house, the run may go through the attic or up through the roof, which is common in two-story Arizona homes. We'll show you the options and the price of each. We don't do roofing or gas work; if your dryer is gas, its gas line stays connected as it is.
How a visit works
- Look at the space. Where the dryer sits, where the nearest outside wall is, and what's in between.
- Plan and price. We measure the route, count elbows and give you the exact price.
- Install. Rigid metal duct, sealed joints, supported run, proper outside hood.
- Test. The dryer runs and we measure the airflow at the outside hood.
