Here are five tips to prepare your HVAC system for hurricane and flood season.

How to prepare your HVAC system for a heavy storm

1. Cool Your Home One to Two Days Before the Storm Hits

When a heavy violent storm hits your area, it may be common to have extended power outages for a few hours (or even days).

However, there is a way to keep your home comfortable despite the loss of power.

First, you will need to lower the thermostat by four to five degrees more than your typical set point temperature a few days prior to the storm.

Next, be sure to keep all the windows and doors closed as much as possible to help preserve the conditioned cooler air inside your space.

When the storm approaches your location, turn off the power to your HVAC system either at the unit (typically it’s a light switch on a red-colored panel located near the equipment or somewhere within the mechanical room) or simply pulling the plug from the power supply.

Hopefully, any power outage will only last at most a day or two, but at least your space will be kept somewhat comfortable during the storm and aftermath.

Most power outages due to heavy storms usually last for around 12 to 24 hours. If you follow the aforementioned steps, you’ll be able to keep your space cool and comfortable during the power outage.

2. Install A Whole-Home Surge Protector

As if wind and rain are not bad enough, the potential for a lightning strike and power surge during a hurricane or storm can have disastrous results for your HVAC system (plus any other home appliance).

HVAC circuit boards and other electrical components can be damaged and result in a system failure to operate properly or safely.

Protect your equipment with a whole-home surge protector in the event of a lightning strike and keep your HVAC unit running through the storm and beyond.

3. Elevate The Outside Condensor Unit

Hurricanes and heavy rainstorms can result in flooding, especially in flood-risk areas. Unfortunately, high amounts of floodwater do not bode well for air conditioning outside condensing units.

If the floodwater infiltrates the condenser unit and damages the compressor and circuitry, it can cost you thousands of dollars to repair or even replace the unit. Also, keep in mind that many condenser manufacturers also experience weeks of backstock issues during peak summer demand months.

If your outside condensing unit is in an area prone to flooring, then you may want to consider elevating the unit above ground on a platform or brackets attached to the home.

CAUTION: when elevating the outside condensing unit, you’ll need to be careful not to damage the copper refrigerant line sets and other materials and components.

Replacing or repairing damaged refrigerant line sets is another costly mistake that can easily be avoided. That’s why it’s a smart move to have a professional HVAC service technician be responsible for the safe elevation of your outside condensing unit.

Not only are HVAC service technicians experienced and knowledgeable in this type of work, but they are also equipped with the right tools and devices needed to ensure your newly elevated and secured outside condensing unit will run optimally in its new location.

4. Clear Away All Debris And Furniture Near The Outside Condensing Unit

Sometimes storm winds can reach in excess of 160 miles per hour. At this speed, any object that is not secured will take flight and potentially strike your outside condensing unit. That’s why it’s critical to remove any debris and other unsecured objects near the condenser in advance of the storm.

This also includes any weak or loose branches from nearby trees and other shrubbery. It’s also worthwhile to sweep up any loose leaves or dust near the unit as well.

5. Cover The Outside Condensing Unit

As a final step, it may be wise to cover the outside condensing unit (be sure it is not in operation when covered) with a properly secured tarp or cover specifically designed to protect an AC condenser unit.
