Valley doors work through long hot summers and sudden monsoon storms, so check the seal, the sensors and the release handle before June 15. Wipe dust from the sensor lenses, test the reversing feature monthly and know how to run the door by hand when the power fails. A door that feels heavy or sits crooked needs a technician.
1What the Valley asks of a garage door
Phoenix has an average July daily high of 106.5 degrees and about 111 days a year at or above 100 degrees, according to the climate table on its Wikipedia page. The same page gives June 15 to September 30 as the official monsoon season. A garage door is a large moving part that works every day through all of it.
The National Weather Service says thunderstorm gusts in the Southwest almost always exceed 40 mph and the strongest can exceed 100 mph. Dust storms arrive suddenly and usually last only a few minutes, but they leave grit on tracks and sensors and sometimes the power off.
2What to check by season
| Season | What to check | Why it matters |
|---|---|---|
| Spring | Bottom seal, rollers, hinges and how the door sits in the track | Fix worn parts before the hot months and the first storms |
| Early summer, before June 15 | Release handle, remote batteries, sensor lenses | Storms can cut power and dust can block the sensors |
| After a dust storm | Wipe the sensor lenses and look along the tracks for grit | A blocked sensor stops the door from closing |
| Autumn | Door balance, noise and opener travel | Quiet weather is the time to book bigger work |
A technician confirms the cause on site.
3Power cuts and the release handle
When the power fails the opener cannot lift the door. Pull the red release handle, then lift the door by hand only if it moves easily. A door that feels very heavy has a spring or balance problem, so stop and call. See what to do in a power outage.
Once the power is back, reset the door and watch one full cycle. The U.S. Consumer Product Safety Commission advises testing the reversing feature of your opener every month.
4Homes and doors across the Valley
The Census Bureau's 2020 to 2024 survey puts the median home year at 1991 in Scottsdale, 1984 in Tempe, 1997 in Chandler and 2005 in Surprise. About 85.7 percent of Surprise homes are single-family detached, against 67.5 percent in Chandler, 52.4 percent in Scottsdale and 38.1 percent in Tempe.
Newer subdivisions mostly have attached two-car garages. Older areas and apartment-heavy parts of Tempe have more carports, shared garages and older doors, where an original opener may be much older than the door.
5Permits and contractors
Permit rules belong to each city. The City of Phoenix lists new homes, remodels and garage conversions as permit work and does not name garage door replacement on its residential page. Ask your city building department before a full replacement.
Under Arizona law a person without a contractor license may only do casual or minor work under a price cap, and not work that needs a local permit. You can check any contractor with the Arizona Registrar of Contractors.

Questions people ask
When does monsoon season start in Arizona?
The National Weather Service counts June 15 as the first day of the monsoon season, and the season ends on September 30, according to the Phoenix Wikipedia page. Check your door before mid-June.
Why won't my garage door close after a dust storm?
Dust on the safety sensor lenses is a common cause. Wipe them with a soft cloth and check that both sensors face each other. If it still will not close, call for service.
How often should I test my garage door opener?
Test the reversing feature every month, as the Consumer Product Safety Commission advises. If the door does not reverse, have it checked.
Can I open my garage door by hand in a power cut?
Yes. Pull the red release handle and lift only if the door moves easily. If it feels heavy or crooked, stop and call a technician.
