Many HVAC systems have an external component, usually housed in a metal compartment. These components are designed to withstand harsh outdoor conditions, but are they safe from heavy winds and rain? Is storm damage a real problem for your HVAC system? One of the leading air conditioning companies sheds some light on the matter here.
Rain Is Generally Harmless
HVAC experts will tell you not to worry too much about the outdoor component being exposed to rain. In fact, some rain may even be beneficial because the rainwater can wash away any dust and help cool the radiator fins. Any electrical components are also insulated to withstand harsh conditions, provided they’re checked on a regular basis.
When Is Rain an Issue?
There are some situations where the rain that accompanies a storm can affect your HVAC system, but that’s less about the unit and more about what’s around it. For example, if your unit is near an area that’s normally dusty on a dry day, heavy rain can cause mud to splash about and get caked on the unit. HVAC and furnace companies will tell you that mud on the radiator fins can have a negative effect on your HVAC system’s cooling efficiency.
Wind and Impact Damage
The biggest threats to your HVAC unit when it’s storming are wind and impact damage. An exceptionally-strong gust of wind can send debris crashing into the HVAC unit’s outdoor component. Leaves can get blown into the grill as well, preventing the radiator fins from dissipating the heat properly. In a worst case scenario, twigs and other debris can get inside the unit, jamming the fan and causing mechanical damage.
Staying Safe Through Maintenance
The best way to reduce the risk of storm damage to your HVAC unit is by having it checked on a regular basis. HVAC and electric panel companies also recommend trimming back nearby foliage. It’s important to pay attention to any seals and insulating material for the coils and wires to prevent moisture from seeping into the more vulnerable parts of the unit.
