3 Ways Rain Affects Your Portland Home’s HVAC System

In the Pacific Northwest, we get our fair share of rain. While we’ve all come to love our misty months, sometimes excessive precipitation can be a bit much, especially for your home’s heating and cooling system. Want to know more about ways rain can affect your HVAC system? Our local heating and cooling contractors in Portland explain all you need to know. Read on for more details. 

What To Know About HVAC Systems and the Rain

The majority of your home HVAC system components are located indoors, where they are protected from the elements. However, some outdoor air conditioning units can be exposed to rain, snow, and hail. The good news is, even outdoor residential heating and cooling units are sturdy machines built to withstand most weather events. 

While you typically don’t have to worry about a little rain affecting your air conditioning and heating mechanisms, it’s always a good idea to be aware of any potential issues that could arise due to extreme rainfall. Here are three cases where rain can prove problematic and some signs you should look out for. 

1. Flooding

Standing water and flooded areas due to heavy downpours can cause serious damage to the condenser coil and compressor. To mitigate this problem, work with your Portland HVAC contractors to determine the optimal placement for your system. You might be able to simply raise the condenser to prevent pooling water. In other cases, it could be best to move the entire unit to higher ground. 

If you notice your air conditioner is submerged in water, we recommend turning off the unit entirely and call in our professionals to evaluate the situation.

2. Severe Storms

During extreme storms, debris and severe weather like hail can harm your condenser. While we can’t always predict weather patterns, there are a few things to consider to help keep your air conditioning system safe and secure. 

Keep the area around your unit clear of potentially harmful materials like fallen branches, pebbles, and foreign objects. After a significant weather event, check on the system and inspect it for any damage. If you notice any cracks, dents, or other external issues, our NATE-Certified technicians are here to assist you with the best repair or replacement options.

3. Condensation

This most often occurs when homeowners completely cover their outdoor air conditioning and heating units during wet months. To work correctly and resist moisture accumulation, condensers require adequate airflow. Covered units can trap moisture and impede ventilation, causing mold and mildew, and even system malfunction. 

However, whether it’s best to cover or not cover your outdoor unit can depend on a variety of factors, like average temperatures and the type of cover used. It’s ideal to consult with your Portland HVAC installer to make sure you are taking the best care of your machine.
