Can You Run 2 AC on 30 Amp – All You Need to Know

The summer months might be one of the most enjoyable times to travel in an RV or camper. The weather is pleasant, the days are longer, and numerous tourist sites to choose from. No matter if you’re traveling with your family or visiting your grandchildren, now is an excellent time to go on a trip. It might also be scalding when traveling during this time of year.

Yes, you can run two air conditioners on a 30-amp service, but there will be no power left over anymore. One of the A/C units may trip the breaker. You want to be as comfortable as possible on your journey, and you will most likely not be able to do so if you do not have air conditioning. Many recreational vehicles and campers are equipped with air conditioning.

Depending on the size of your car, the destination you’re visiting, and the number of people you’re traveling with, you may require an additional unit to ensure complete comfort. When adding additional air conditioners to your RV or camper, here are some pointers to help you get through the procedure successfully.

1. Buy a quality air conditioner

Everyone strives to get the most out of their money to get the most out of their dollar. However, keep in mind that there are some things you will not be willing to give up to obtain a lower price. If you purchase a costlier air conditioning unit, it will achieve a few things. It will, for starters, most likely cool a more significant area more efficiently than currently available technologies.

It will almost certainly be more energy-efficient as well as more environmentally friendly. So, if you’re wondering whether or not this will make a difference, I’m here to tell you that it does. When it comes to energy consumption, air conditioners are the worst offenders. You will be charged for that energy.

At the end of the season, you may discover that the cost of operating your low-cost air conditioner was higher than the sum of the purchase price and operating costs of the higher-priced model. Quality air conditioners are still available at a reasonable price. Don’t expect the least expensive unit in the store to perform the same functions like a more expensive unit.

Please make no mistake: installing a second air conditioner in your recreational vehicle will require additional financial resources. Considering the savings on the alternative — hotel rooms when it’s simply too hot to stay in your RV — is a no-brainer.

2. Use what you have

Use what you have

For those of you who have been reading up on all of the latest and best air conditioning alternatives for an RV or camper, you may already have a clear notion of the unit you want to install. Always double-check that your initial unit is in perfect working order.

Price will almost certainly become a consideration for you, but the car you begin with will have a significant impact on the type of system you choose. A ducted system is an integrated system in which air goes through ductwork to cool your room in an even distribution.

When it comes to cooling an area, ducted air conditioners are ideal. If your camper or RV does not have ducts, however, retrofitting it for a ducted system is not likely to be within your financial means—or even be very practical.

Ductless air conditioners are standalone cooling devices that do not require any ductwork. They are only installed in one location, and it is in this location that the cool air is generated. This window unit will move around the room from its origin, much like a traditional window unit would. An air conditioner system with no ducts is still an excellent option to create a more relaxed living environment.

It’s only a matter of keeping a few considerations in mind as you choose your installation location. It will always be the coldest in the unit’s area. Please make an effort to install the unit very far away from the resting or lounge area so that everyone in the RV will be relaxed while it is in use for the best results possible.

3. Location


When deciding where to locate the second air conditioning system, there are a few considerations to consider. The kitchen or the bathroom is not ideal for your new unit to be installed.

Placing an air conditioner in one of these locations almost often necessitates the removal of a circulation vent. Losing ventilation is not an option in the kitchen and bathroom when humidity and condensation are at their highest.

It would help to place the air conditioner in a well-ventilated area as a basic guideline. Trying to install it in a small room, such as the bathroom, will keep that small space extremely excellent without traveling to other areas.

In addition, you’ll want to locate the air conditioner in the most heavily trafficked area of your home. In the case of a second air conditioner in the vehicle, it will be of little use if you are never near it to take advantage of its cooling capabilities.

One final word of caution when deciding where to install the second air conditioner. For example, if your vehicle’s first air conditioner is mounted on the roof, you’ll want to look for a different location for the second air conditioner to be placed. Most recreational vehicles (RVs) will not be able to support the weight of the wiring required for two air conditioner units on the roof.

Can you run two air conditioners together?

It is possible to have a single air conditioning unit for a two-story house. An air conditioner with two zones and a single unit that powers both air conditioners is required. Two air conditioning units (one upstairs and one below) in your home might help keep the temperature balanced. Here, a compact split air conditioner is the ideal solution.

Can you run a 15000 BTU air conditioner on 30 amps

Air conditioners can be run on 30 amps as long as no other appliances are being used in your RV at the same time. It may be possible to run both air conditioners on 30 amps in some newer models that are more energy-efficient. As a result, it is preferable to evaluate the typical power consumption of air conditioners because excessive power consumption could pose a safety hazard.

In most cases, an RV’s air conditioner can be operated efficiently at 15 to 20 amps. However, this is only applicable if the business is conducted following specific standards and regulations. More than one air conditioner can’t be operated on a circuit with a capacity of 30 amps.

When it comes to your RV’s air conditioners, you can use a single 30-amp circuit, but there’s a catch. It permits you to do so long as you refrain from utilizing any other electrical device.

Check the air conditioner from Amazon.

In most cases, when you plug an RV air conditioning unit into a circuit with 15 or 30 amps, the other devices on the circuit will also be turned off. Because it immediately shuts down the others, it helps to avoid tripping the circuit breaker.

Older RV designs have larger air conditioners installed, so keep that in mind when shopping. It is less probable that both RV air conditioning units will run on 30 amps if you choose an older model; therefore, consider purchasing an older model.

Will an AC run on a 30 amp?

A 30-amp circuit cannot be used to power both air conditioners on a recreational vehicle in most circumstances. You will not trip the circuit breaker on the power source if you use your AC on a 15 or 30-amp circuit since it will switch off (shed) any other appliances connected to the circuit.

The energy management system

The energy management system

Every RV is equipped with an automatic system that regulates the amount of electricity consumed by the equipment. When an air conditioner is running, the energy management system automatically turns off any other electrical appliances currently in use.

The technology takes care of electricity consumption by appliances by estimating the amount of stored energy available in the RV.

Although it may pose a risk, some RV owners choose to modify their electrical systems to include a standalone 15-amp holder. Alternatively, they can now connect their RV air conditioners to a 15-amp circuit if they so desire.

Final verdict

You can safely operate your ACs by connecting them to a 30-amp circuit as long as you only use them rarely. However, you must monitor the amount of power your RV’s air conditioners consume and resist exceeding the limit because safety is paramount.

So, if you’re wondering if you can run an RV air conditioner on 30 amps, I feel this post covers all the bases. Thank you for taking the time to read, and please remain safe.
