Rain is one of the most common weather conditions that affect HVAC units, but how much damage can it really cause over time?

In this blog post, we’ll explore the impact of rain on your HVAC system and provide tips for protecting it from water damage. So grab a cup of coffee (or tea!) and let’s dive in!

What Your HVAC System Consists

Your HVAC system is the critical component of your home that keeps you comfortable in all weather conditions. It consists of two main parts: the outdoor unit and the indoor unit. The outdoor unit contains the condenser coil, compressor, and fan motor, while the indoor unit houses the evaporator coil and air handler.

The condenser coil is responsible for releasing heat from inside your home to outside. The compressor pumps refrigerant between both units, transferring heat from one location to another. A fan motor blows cool air over these coils into your home or office space.

The evaporator coil absorbs hot air from inside your living space and cools it down using refrigerant before blowing it back out through ductwork or vents in various rooms.

Additionally, an air filter helps keep dust particles out of your HVAC system by trapping them before they enter either part of this vital machine!
