June 15th officially marks the official start of Arizona’s monsoon season. With temperatures well over 100 degrees and the dry heat of summer settling in, the rain is welcome with open arms! The damage to your home from a monsoon can be devastating and wreak havoc if you are not prepared. Along with monsoon season comes several issues that can be destructive to your air conditioning system. We’re reviewing the most common monsoon season issues, what damage they can cause to your systems, and how to prepare for them.

Dust Storms

Arizona residents often refer to dust storms as haboobs, which are large walls of dust that can be several miles wide and have wind speeds up to 60mph. These dust storms can have a significant impact on your air conditioning unit.

Your outdoor unit, while built to withstand the elements, can be coated in dust after a haboob. When the coils are coated in dust, they cannot function properly and can cause the unit to completely fail. Checking your unit after the dust storm has cleared is important for its efficiency along with having the coils cleaned at least twice per year. 

The dust from a haboob can also get inside your home through leaking ducts or roof vents in your attic. Sucked into your ductwork, the dust circulates through your home and the indoor unit coils. This can cause your AC unit to perform less than normal and the efficiency to drop even more. A skilled HVAC technician can test for any duct leaks and repair them before monsoon season to help prevent this.

Power Outages 

Of course, during monsoon season, heavy rains and winds are often in the forecast along with strong forces of lightning. During this time, power outages and brownouts are frequent occurrences which can cause harm to your air conditioning unit. Two most common reasons your AC unit isn’t functioning properly after an outage include a tripped breaker or damaged part from a power surge. 

A tripped circuit breaker is relatively easy to identify. Simply locate your breaker box and check to see if any of the buttons are switched to the “OFF” position. If so, flip it back and monitor the cooling of your home for about an hour. If the breaker flips back to the “OFF” position, you may need to call a professional. 

Power surges occur when the power is restored to your home after an outage. While the power surge doesn’t last, think less than 1 second, it can cause significant damage to your appliances. Due to the nature of the electrical components contained within your air conditioner, it is recommended that a professional examine your system if you are having problems after a power outage. A surge protector can help protect your units and components from failure after a power surge. This device can be easily installed and save your wallet from future failures.


While not often thought of as a problem in Arizona, high levels of humidity inside your home can cause issues for your AC system. The excessive rain from the monsoons creates moisture, which results in escalated levels of humidity. Mold growth is common with too much humidity within your home. This can lead to an uncomfortable sticky air feeling, unpleasant odor, health problems, and structural damage if not properly cared for. One way to maintain a comfortable humidity level within your home is to install a whole house dehumidifier.
