Monsoon season here in Arizona can be rather unpredictable each year. Starting in June and coming to a close at the end of September, we are still left with nearly two months of potential downpours, dust, and thunderstorms.
Due to the conditions, many Arizona residents will experience first hand the damage that water can do to a property. The outside flooding can quickly turn into inside flooding as a direct effect of the rain if water breaches poorly sealed windows and doors. BUT surprisingly that is not the main way these monsoons cause flooding on most properties. Most leaks during this season actually come from your A/C unit (HVAC System) inside your home..
BUT HOW DOES AN A/C UNIT HAVE ANYTHING TO DO WITH FLOODING WATERS?
There really is only one component that involves water with the standard HVAC. That component is the condensation line. When air is either heated or cooled from your HVAC, it creates humidity. This humidity eventually turns into condensation and it must empty out away from all the mechanical components of the A/C unit. The primary function of the condensation line is to drain all of that excess moisture. This line starts at the HVAC system (generally located in the attic or a utility closet) and reaches all the way to the outside of your property where it can be evaporate into the air.
When the monsoons come it brings the rains with, and with rain comes humidity. Unfortunately, the rain does not do a good enough job lowering our valley's summer temperatures all that well, so this leaves the average person still running the air conditioning in a hot and now extremely humid environment. With the abundance of moisture, an A/C unit will be producing way more condensation than normal.
Over time the condensation line coming from the HVAC naturally collects dirt, dust, and debris and may eventually collect enough to where it can become clogged. A clogged line may not cause any problems during normal dry conditions, but with the excess moisture from the monsoon rains, the condensation has nowhere to drain. The water will then collect and overflow from the drain pan that sits under the A/C Unit, ultimately causing water damage to ceiling, walls, floors, and other structural parts of the property.
Our #1 Tip to prevent flooding during Monsoon Season is to clean out that condensation line before the storms or rainy season starts. You may want to check every 1-2 years for clogging or hire a professional A/C company to check the line and flush it if necessary. There are also DIY methods that use at home materials to clear the condensation line at virtually no cost.
This one tip can save you a heap of trouble. Our #1 tip will take less than an hour, but will end up saving you lots of time and money. Our A/C Unit can be our best friends here in the Arizona summer, but come monsoon season you may find it to be at the height of your problems.
