Although a hurricane's path is unpredictable, there is ample time for those in the predicted path to prepare to weather the storm. The pre-storm preparation may help minimize property damage and as well as damage to mechanical and electrical systems -- the literal "engine" of all businesses. Check out this post for tips on protecting your air conditioner from a hurricane. FEMA has great resources for what to do before, during and after a hurricane.
For mission critical environments, server rooms and data centers, it's wise to have emergency air conditioners on site. If you do not own back-up air conditioners, you can rent emergency spot coolers to have on site. Many companies will have a fee structure with a "stand by" rate that is charged so the units are in place in case they are needed. A higher rental rate is charged if the units are actually used.
Once you've done all you can to protect your mechanical systems from a hurricane you need to make plans for what will happen once the storm has passed. Once any the threat of damage to life or property has passed, here's where you start.
Let's be honest. We have absolutely no control over how destructive any hurricane will be but the best and fastest plan to recover quickly is PREPARATION. Download this checklist to make sure you'll be ready for a cooling emergency.
