Do Air Conditioners Need a Dedicated Circuit?

Many homes utilize an air conditioner when temperatures start to rise. Air conditioners are available in a range of sizes and capacities to suit the needs of different homes and buildings. Some are smaller and portable while others are mounted to a wall or connected to a central system. Though smaller units can be used with standard outlets, larger air conditioners do need a dedicated circuit.

What Air Conditioners Need a Dedicated Circuit and why?
It is important to know how to determine if an air conditioner requires a dedicated circuit before purchasing it or plugging it in. A good rule of thumb is that units with a rating higher than 15,000 BTUs will require a dedicated 220-volt circuit. Some air conditioners also feature a non-standard plug, indicating that it may require a dedicated circuit.
Some of these circuits are built directly into the wiring of a home, while other homes will feature a dedicated 220-volt plug for an air conditioning unit. If a larger air conditioning unit is plugged into a standard outlet, it will likely trip your breaker during start-up. Even if a large unit can be powered with a standard outlet, prolonged usage can result in damage to the air conditioner or your breaker, so a proper outlet and dedicated circuit are crucial.
How to Tell if You Have a Dedicated Circuit
There are several simple methods to check if you have a dedicated circuit:
- Check your breaker panel. If a dedicated circuit is installed in your home and was labelled properly, there should be a label titled “air conditioner” or “AC”. Some other appliances such as ovens, refrigerators, garburators, and dishwashers may also be labelled.
- If none of the panels are labelled, check the outlets that some of these appliances are plugged into. If these outlets are not standard 120-volt receptacles, they may be on a dedicated circuit.
- Does your breaker constantly trip when using certain appliances together or turning the air conditioner on? If so, you likely do not have a dedicated circuit and will need to have one installed by a certified electrician.
