What You Need to Understand About HVAC Systems and the Rain

Keeping your HVAC system working efficiently is often a top priority. Scheduling routine HVAC maintenance is essential to maximizing the lifespan of your system and saving you money in the long term. Fortunately, HVAC units are designed to handle harsh weather conditions, which is especially important if you ever deal with excessive rainfall.

Here are a few things you need to know about how your HVAC system can handle the rain.

• Is Your Outdoor Unit at Risk in the Rain?

The outdoor heat pump unit is the only part of your HVAC system that’s more susceptible to damage if you live in an area prone to flooding. Water that begins to submerge the unit can cause numerous problems with the electronics, wiring, and motor. While the heat pump can easily work in the rain, it can’t work while submerged in water. The safest option is to turn off your HVAC system at the electrical panel if you are experiencing a flood. You will need an HVAC professional to check your system before you turn it on.

• Do You Need to Cover Your Outdoor Unit?

Covering your outdoor unit isn’t necessary because it is built to withstand harsh conditions. Choosing to cover your unit can even lead to corrosion and other issues without you even knowing it. Not stacking anything on top of your unit is also essential, especially if it’s running, as it needs proper airflow. You might be able to build an awning-type shelter to protect your unit from falling debris, but it’s a good idea to reach out to an HVAC company before you take this extra step.

• Do HVAC Professionals Service Units in the Rain?

Technicians will not service outdoor units while it’s raining due to the danger of working on electrical components. Moisture can also cause damage to the system, which is why technicians will wait until the rain is over. The rain also causes dangerous conditions for units on the roof due to the chance of slipping or experiencing high winds. Waiting until everything is calm is well worth it to stay safe.
