One problem people often encounter when installing a new air conditioner is where to plug it in. HVAC appliances are some of the most powerful electrical equipment in buildings, accounting for most electricity expenses. With such a power load, it’s imperative to plug the air conditioner into the proper outlet type — but can you plug an air conditioner into a power strip?
As Hickory’s reliable AC installation professionals, Hickory Heating & Cooling in North Carolina understands the dangers of plugging a high-powered appliance into a standard power strip. Below, we share details about the problems this practice can cause and safer ways to power an air conditioning unit.
Power Surges and Air Conditioners
Every appliance needs a specific electrical load or power consumption level to work correctly. If an electrical device takes more power than necessary, it can create a power surge. Power surges are dangerous because they can damage the appliance beyond repair and trigger an electrical fire.
Because air conditioners require a massive electrical load, it’s usually best to plug one directly into a wall outlet. Updated HVAC equipment contains components that are sensitive to electrical fluctuations. Even a minor power surge could result in the need for AC repairs, so taking protective or preventative measures against power overloads is ideal.
Plugging AC Units Into Power Strips
So, can you plug an air conditioner into a power strip? The answer is no, at least not for a standard power strip.
A common misconception about power strips is that they offer some protection against power overloads. Though they appear to be more than a standard outlet or electrical cord, power strips are electrical accessories that increase the number of outlets for a receptacle. Plugging a high-powered air conditioner into a power strip is dangerous and can cause an electrical fire.
Installing a surge protector for your air conditioner is a better option if you can’t plug it directly into a wall outlet. Surge protectors resemble power strips but protect against power surges. Still, not all surge protectors are the same.
Every surge protector has a joule rating, which determines how much energy the accessory can absorb. For instance, if lightning strikes on or near your home and causes a power surge, the surge protector can absorb some of the excess and prevent damage to your appliances if its joule rating is high enough.
Are Extension Cords Better Than Power Strips for ACs?
Depending on your air conditioner’s location, you might wonder whether you could use an extension cord to plug the equipment into a wall outlet that’s a little out of reach for its cord. Though extension cords are suitable for many electrical devices that can’t reach wall outlets, they’re unsuitable for appliances that require heavy-duty usage, like air conditioners. The cable isn’t strong enough to handle the electrical current.
Using electrical cords for high-powered appliances usually causes the cables’ rubber coating to melt off from the heat of the electrical current. This is a major fire risk and not ideal for your air conditioner.
How To Safely Plug in an Air Conditioner
When installing a new air conditioner, try plugging it into a dedicated wall outlet for optimal efficiency and safety. If you must plug your air conditioner into a power strip, ensure it offers surge protection and has enough capacity to accommodate the AC unit’s electrical load.
Check the capacity by reviewing the following details on the power strip and air conditioner:
- Wattage limit
- Amperage
- Voltage rating
Multiply the amperage and voltage rating of your new air conditioner to determine its wattage. If that figure doesn’t exceed the strip’s wattage limit, it’s safe to use.
