How Heavy Rains Can Impact Your Air Conditioning Unit
Rain and the effect on Your AC System Rain is often seen as a blessing, but excessive amounts can lead to serious issues, mainly when flooding occurs. Hurricanes, flash floods, and severe storms can unleash significant rainfall, resulting in water levels exceeding a foot or more, causing extensive damage to homes and businesses. So, how do heavy rains affect your air conditioning (AC) unit?
Understanding the Effects of Rain on Your AC System
Resilient AC Units
Rain affects your air conditioner. Modern air conditioning units are built to endure various weather conditions, including rain, snow, and hail. The outdoor components protect the internal machinery from precipitation, ensuring performance remains stable even during inclement weather. Electrical parts are sealed, and connections are made resistant to moisture. The compressor and condenser units, typically made from durable materials like aluminum and copper, are engineered to withstand heavy rainfall while effectively cooling and dehumidifying your home. However, heavy rains can lead to other complications:
Potential Storm Damage
Severe rain accompanied by strong winds can send debris flying, damaging the condenser fan grille or allowing leaves, twigs, dirt, and other materials to enter your AC system. After a storm, it’s wise to scrutinize your outdoor unit for any signs of damage or debris accumulation.
Risk of Flooding your Air Conditioning System
Localized flooding can pose a significant threat to your air conditioning system. Water levels exceeding 15 inches could compromise moving parts and electrical components. In severe flooding, it is crucial to have your unit professionally inspected before restarting it. Installing your outdoor AC unit in a flood-safe area is essential. Additionally, ductwork and venting under pier and beam structures must be safeguarded against floodwaters to ensure safe operation and the health of your household.
Corrosion Concerns
Internal corrosion may develop if your system isn’t properly covered during the off-season. If you cover your AC unit, use a commercially available cover with ventilation holes. Avoid using plastic wrap or garbage bags, as they can trap moisture and condensation inside, leading to the deterioration of wires and rubber and rusting metal components. Inadequate ventilation can also encourage the growth of mold and mildew, creating a welcoming environment for pests and vermin.
