Not every day can be fair and sunny, but how do rainy days affect your HVAC system? You might not notice much from inside, but the weather does have an impact on your heating and cooling systems. Depending on how much rain there is, it can be helpful for your unit, but it can also be a problem as well. In today’s blog, let’s talk about the effect of rain on your AC and what you can do — if anything needs to be done — to protect them.
Natural AC Cleaning
Rain can be a relief in the midst of a hot summer, and it can also be a boon for your AC unit. Rain cools the evaporator coils of your AC unit and naturally washes the dust away, so the AC unit is able to run more efficiently. In fact, you want it to rain sometimes during AC season for this very reason. However, if you have a particularly dry summer, you can always schedule an AC tune-up in order to have your AC cleaned and optimized.
Some homeowners might be concerned about the potential dangers of rain interacting with the electrical components of your HVAC systems. It’s a valid question, since electricity is a big part of these systems, but remember that outdoor units are built to withstand the elements outside. The coils of your air conditioning unit are insulated to protect from water interacting with the electrical aspect. That’s also why it’s important to make sure your AC unit is in good shape and that all of those protections are still in place.
Window units are also built to withstand rainy weather, but you want to make sure the opening around the window unit is properly sealed and protected so that rain doesn’t seep inside.
If you experience heavy rains, such as a flash flood, you could potentially run into issues with short circuiting or damage to the AC unit. Thunderstorms are problematic as well, as lightning could strike the unit and damage it. Strong winds can also harm your AC units. That’s why if the forecast calls for heavy storms, you may want to unplug window units and turn off central AC units. After the storm, check for any damage and remove any debris so that the unit can run efficiently. If you need any repairs or a tune-up, call an HVAC technician as soon as possible.
