HVAC systems are crucial components in maintaining indoor comfort and air quality in both residential and commercial buildings. However, during hurricanes and other natural disasters, they are susceptible to significant damage — and with Hurricanes Helene and Milton causing mass destruction, we must examine hurricane preparedness.
High winds can dismantle exterior units, prolonged power outages can render systems inoperative, and floodwaters can infiltrate and ruin components beyond repair. Understanding these vulnerabilities is the first step in protecting these systems from potential storm damage.
Conducting a Pre-Storm Inspection
Before the onset of hurricane season, it’s advisable to conduct a thorough inspection of your HVAC system. Check for any pre-existing issues that need repair, such as:
- Loose parts
- Worn-out electrical components
- Blockages in air vents
On top of that, ensure that the unit is securely anchored, especially external units, to prevent them from toppling over during strong winds. Regular maintenance checks by a professional can identify potential weak spots that might not be obvious at first glance.
Securing Outdoor Units
One of the most vulnerable parts of an HVAC system during hurricanes is the outdoor unit. Use hurricane straps to secure the outdoor condenser to its base. It’s also wise to cover the unit with a specially designed tarp or cover to protect it from flying debris. While covering, be mindful not to wrap it too tightly, as this can lead to moisture accumulation inside the cover, leading to rust or mold. Additionally, consider installing a barrier or fence around the unit to offer additional protection from wind-blown debris.
Elevating Systems Above Flood Levels
For businesses in flood-prone areas, elevating HVAC units well above anticipated flood levels can significantly reduce the risk of water damage. This might involve installing external units on rooftops or elevated platforms. While initially costly, this proactive step can prevent extensive damage that would result in even more expensive repairs or replacements after a flood.
CANADIAN WILDFIRES: PROTECTING YOURSELF AGAINST POOR AIR QUALITY
Power Protection
Power surges and outages are common during hurricanes. Installing a surge protector for your HVAC system can prevent damage caused by sudden electrical spikes. Portable generators or backup battery systems can provide necessary power to maintain critical HVAC functions during outages, ensuring continuity of operations, especially in commercial settings. However, it’s essential to ensure that any backup power system is adequately ventilated to prevent carbon monoxide poisoning.
Creating a Hurricane Kit for HVAC Systems
Prepare a dedicated preparedness kit for your HVAC system before hurricanes strike. This kit should include necessary tools for emergency repairs, spare parts such as:
- Steel brackets
- Sheet metal screws
- Filters and belts
- Tarps
- Bungee cords
- A list of emergency contact numbers for HVAC professionals
Having these resources assembled in a single location ensures quick access when needed.
Post-Storm Inspection and Repair
After the storm has passed, conduct a thorough inspection of your HVAC system before turning it back on. Check for any visible signs of damage such as bent components, debris trapped in parts of the system, or water intrusion. If there are signs of electrical damage or flooding, call a professional service like Donnelly Mechanical to appraise and fix any issues before the unit is powered up, as operating a compromised system can further exacerbate damage.
Investing in Insurance
Insurance for hurricanes is an essential consideration for businesses in New York City, given the region’s vulnerability to severe weather events. While standard commercial property insurance policies often cover some types of storm damage, they may not fully protect against all hurricane-related losses — not to mention it may come with a high deductible.
Business owners should evaluate policies carefully to ensure comprehensive coverage, including protection against wind and flood damage — two of the most destructive forces associated with hurricanes. For those operating in high-risk zones, investing in additional flood insurance can be prudent, as standard policies often exclude flood-related claims.
It’s also important to verify whether business interruption insurance is part of the policy, as it can provide financial relief for lost revenue during recovery periods. Taking these steps not only safeguards physical assets but also secures the financial stability of businesses during a hurricane.
