How to protect your heat pump during storm season

Like any electrical appliance, heat pumps can be affected by storms. Learn how to protect yours during adverse weather conditions.

Here are some considerations for heat pumps during a storm: 

Power Outages
Storms often result in power outages due to downed power lines or other infrastructure damage. Heat pumps rely on electricity to operate, so during a power outage, they will not function. If you have an electric heat pump, you may lose heating or cooling capabilities until power is restored. 

Electrical Surges
Lightning strikes and electrical surges can occur during storms. These surges can damage the electrical components of a heat pump. To protect your heat pump from electrical damage, consider installing surge protectors or whole-house surge protection devices. 

Heavy rain and flooding can be a concern, especially for outdoor heat pump units. Heat pumps should be installed on elevated platforms or stands to prevent water damage. Flooding can damage the electrical components and reduce the efficiency of the heat pump. 

Debris and Physical Damage
Strong winds and flying debris can potentially damage the outdoor unit of a heat pump. To mitigate this risk, ensure that the heat pump is properly anchored and protected. 

Regular Maintenance
Before storm season, it’s a good idea to have your heat pump inspected and serviced by a qualified technician. They can check for any pre-existing issues and ensure that the system is in good working order. 

Emergency Power Source
Consider having a backup power source, such as a generator, to keep essential appliances, including your heat pump, running during a power outage. This can help maintain a comfortable indoor environment during extended outages. 


Heat pumps can be vulnerable to the effects of storms, including power outages, electrical surges, flooding, and physical damage. Proper installation, regular maintenance, and having a backup power source can help mitigate some of these risks and ensure the continued operation of your heat pump during adverse weather conditions.  

If you’re concerned about your heat pump’s resilience to storms, it’s a good idea to consult with a qualified HVAC technician or contractor from our Efficiency Preferred Partner list for advice on how to protect your system.
