In the event of a power outage, many residents have invested in portable generators to power parts of their homes. Portable generators are great for powering televisions, ceiling fans, lighting, microwaves and even refrigerators. But can a portable generator power your air conditioning system in a pinch?

 

Before powering anything from your generator, ensure that your appliances have a proper connection. In most cases, this is through your circuit breaker box. This requires the use of a transfer switch that needs to be connected to your breaker box. You can then plug a portable generator to your transfer switch connection and flip on the breakers that power the appliances you plan to use.

 

You should always have a certified electrician install a transfer switch, as an improper connection could risk your life or a utility worker’s life. If you need to run an extension cord from your generator to power an appliance, be sure to use an undamaged cord with the properly gauged wire.

 

Both your system and your generator should be rated for a specific number of starting wattage and running wattage. Many appliances (including HVAC) require a power surge to turn on, called starting wattage. Running wattage refers to how many watts an appliance needs to operate. This means that, even if your generator can power a running heating and air conditioning system, its starting wattage also needs to rate higher than your system’s starting wattage.

 

In general, many of the larger portable generators are rated for enough starting and running wattage to power moderately sized HVAC systems. However, if you’re using a smaller portable generator that you typically use to power a few things while tailgating, it likely won’t power your system.

 

Depending on the weather and your preferences, you may not need to use your home’s AC system. Instead, open your windows and use fans or a less-powerful window unit to provide enough comfort.
