Arizona’s official monsoon is June 15th through September 30th. These storms range from minor dust storms to intense thunderstorms. The monsoon usually starts with heavy winds, which can turn into a wall of dust hundreds of feet high moving across the Valley. These dust storms, called haboobs, are often accompanied by thunder and lightning and sometimes lead to heavy downpours. It’s the only season during which Arizonans don’t use the phrase “it’s a dry heat”.
The Arizona Division of Public Health Services describes AZ heat as “more than a nuisance – it is lethal.” And the severity of annual monsoons affects our roadways – including driving visibility and flash flooding – as well as air quality. A 10,000 foot-tall wall of dust, 30 or more miles wide can do a lot of damage, especially to a home’s HVAC system.
Since a home’s air conditioning system filters the outside air, the dust storms that are part and parcel of a monsoon can strain your unit, making it work harder and less efficiently. Because the a/c unit may run longer than normal due to the higher humidity, homeowners may need to lower the thermostat setting in order to keep comfortable. 77 degrees in a 50% humid home does not feel good. Cleaning the unit’s condensate drain will also help keep your HVAC system clean and clear out any debris, which makes the unit more efficient.
Because the electricity often goes out during the monsoon, it’s best to turn your air conditioning unit off so there’s not a huge power draw when the electricity comes back on. In fact, investing in surge protection is also a wise move, considering you’re a/c is the biggest power draw in your home.
