Prepping Your HVAC System for Severe Weather

Posted on January 11, 2022, at 9:18 pm

Each year, the average cost of damage from hurricanes and other severe storms on households across the US can reach an average of $34 billion. Some of the household items that get damaged most often, apart from roofs and windows, are HVAC units.

Your HVAC system is made up of two parts, the indoor evaporator and the outdoor condenser. The condenser is what can suffer the most in a severe storm, but the evaporator can also get damaged.

If you are worried about storm damage to your system, there are some important steps you can take towards protecting HVAC units.

Prevent HVAC System Surges

Lightning strikes and power outages during severe storms can be catastrophic for your HVAC unit. You want to prevent an uneven power surge that can destroy the circuit boards. An HVAC surge protector will shut down the entire system when there is a spike in line voltage.

Intense power surges can destroy the unit immediately, with weaker surges deteriorating it over time.

Cover It and Stabilize It

It is important to protect your outdoor HVAC unit. In a heavy storm or hurricane, your condenser will be in danger of flying debris, which can seriously damage it. You can prevent this by covering it with a tarp or even planks of wood can work as a shield.

There are hurricane straps that you can use for the condenser unit if you know there is a risk of high winds. These straps will maintain the unit where it is.

Turn the Unit Off

Before a severe storm, it is important to turn the HVAC unit off. This can remove the chances of a power surge affecting the unit.

Turning the unit off can also help maintain the condenser. If debris gets into the condenser while it is still running, it can get stuck in there and burn the motor.

Remember that if you want to turn the HVAC unit again after a power outage, you should wait at least five minutes before doing so to prevent variations in electrical power as the system adjusts.

Have It Inspected

Before the storm arrives, you want to have your HVAC unit inspected. Experts will be able to give you an idea of potential issues and to give you even more tips on how to keep the entire system in working condition.

After the storm is over, you want to have the unit inspected again before you start using it. If you notice water or serious damage, do not turn the unit on until you get help from professionals.
