Air conditioning systems typically have one unit installed outdoors. One of the most common questions homeowners ask us is whether or not rain will affect their outdoor air conditioning unit. Local heating and air conditioning service company Shackelford Heating & Cooling takes a look at how rain and air conditioners get along in this post.
The Outdoor Unit
Air conditioners have outdoor units which contain the condensing coil, compressor and a large fan that creates airflow. Part of the air conditioner’s cooling process involves passing compressed refrigerant through the condensing coil, which with the aid of the fan dissipates heat collected from the indoor space. Outdoor units are built with vented or perforated enclosures to maximize airflow.
Despite their electrical components, outdoor air conditioning units are designed to withstand typical outdoor conditions, including rain. Sensitive electronics are housed in water-resistant casings that protect them from most types of moisture damage. This means you don’t have to call for an air conditioning repair service every time it rains in your area.
Rain Can Help Your Air Conditioner
You might be surprised to learn that rain is actually favorable towards your air conditioner because it helps cool the condensing coil. Rain helps remove dirt, dust and twigs that may have accumulated on the cooling fins and the coil itself as well. A clean air conditioner is more efficient at dissipating heat from the coils and is less at risk of overheating. While rain can be helpful for homeowners who’ve been neglecting their air conditioner cleaning routine, this doesn’t replace a thorough cleaning conducted by a professional.
What About Extreme Weather?
Despite their weather-friendliness, air conditioners aren’t completely resistant to damage caused by extreme weather. Flooding caused by heavy rain or leaky gutters can submerge the outdoor unit and result in damage to its electrical and electronic components. If this happens, it’s best to turn the air conditioner off at the circuit breaker. If flood water enters the enclosure, don’t turn it on again until your HVAC technician has pronounced it safe for use.
