Living in Hawaii, you are pretty much well aware that June through November is hurricane season. There’s been a few that have hit Hawaii hard, such as Inki in the 90’s and Ewa in the 80s. You may be familiar with the general preparedness steps you need to take for your home during hurricane season. But there is one aspect you may not be familiar with and should still take the necessary steps to prevent damage to your home’s HVAC unit.

What To Do Before The Hurricane

Before a hurricane/storm hits you should have your HVAC system inspected if it hasn’t been done so yet. Maintenance inspections are not only helpful in preventing future problems but also before storms.

  1. Turn off your HVAC system before any approaching hurricane or storm. If you have a unit that is in the window, be sure to unplug it, remove the ducts and unit from the window, then seal the opening. Shut off the breakers that lead to the unit to prevent any damage.
  2. If your unit is outside, be sure to cover it with a tarp or plywood and tie it down with hurricane straps to give your unit protection from strong winds and prevent any debris from getting inside.  If you don’t already have them, get the right hurricane straps and a cover designed for your unit.
  3. Protect your AC’s electrical components by investing in a surge protector for your unit. A storm can cause power lines to fall on your home or lightening to surge through. These surges not only cause you to lose power in your home but can also ruin the electrical components of your HVAC system.

After A Hurricane

  1. Once a hurricane or storm has passed, don’t turn your AC back on right away. First, you will need to remove the cover of your AC. Your AC system may have been exposed to water, even just a small amount can cause damage and corrosion. It could be running fine for a few weeks, then unexpectedly fail.
  2. Inspect the unit and the area surrounding it to make sure the AC is still in working condition. Inspect your ac unit for any damages that may have been caused from fallen debris. You also want to check for any sort of obstruction in the airflow that may prevent the system from working.
  3. Arrange for a professional HVAC technician to make sure that no damage has been done to any of the refrigerant or electrical lines that run from your AC.

If your HVAC system has been exposed or damaged by flooding or winds during a hurricane or storm, some of the components of the unit might possibly need to be replaced. A certified technician will be able to tell you what or if any parts need replacing after they have inspected it.
