Event Cooling: Back to the Basics

When it comes to party planning, even the most beautiful and festive décor will not count for much if guests are sweltering or shivering. Using the right portable cooling or heating equipment is vitally important to the success of an event. Here are the basics of providing portable equipment rentals for climate control in tents and other party locales.

How Can I Keep My Party Tent Cool?

An air conditioned tent makes for comfortable guests at an outdoor wedding, party or other event. Party tent air conditioner systems can be installed inside or outside of the tent. Read on to learn about the options.

Large 12- and 25-ton mobile air conditioning units are popular for event cooling because of their high cooling capacity. These units will typically be located outdoors with the cold air ducted in. Sometimes, however, multiple spot coolers of 1- to 5-ton capacity can do the job, and these air-cooled units may be located indoors or out depending on noise and space constraints.

Some customers prefer to use two or three smaller units instead of a single larger machine to provide redundancy in the unlikely event that one of the units experiences component failure. Once you’ve determined what layout you’d like, it’s time to consider how much cooling power you’ll need. Read on to learn more about cooling recommendations based on tent size.

How Much Cooling Does My Tent Need?

Having sufficient airflow to the tent is crucial for a steady and comfortable climate. As a rule of thumb, plan on one ton of cooling for every 100 to 150 square feet of area within a tent. That can add up to a lot of tonnages, but it will be needed to compensate for the thin walls of the tent and the resulting high level of air infiltration.

Whether you opt for the low or high end of this range will depend on the calculated heat load, which must take into account factors, including:

Since comfort is a big part of success, it is wise to build a little extra cooling capacity into the game plan for your air conditioned tent.

If the event is to take place indoors, the formula changes to about one ton of cooling for every 400 to 600 square feet of space. Again, the heat load must be calculated as above to determine more precisely how much cooling is needed. An experienced portable air conditioner company can help you determine the best course of action.

Portable Cooling in Open Tents and Open Areas

Portable AC for tents is not the only option for keeping guests cool. Another popular rental option for outdoor event cooling in open areas or open-sided tents is misting fans.

The Power Breezer misting fans have a cooling range of 3000 square feet and can cool a space up to 27 degrees without getting guests wet. Misting fans are compact, quiet and easy to assemble, ideal for various applications, including commercial sites and sporting events.

Operating the Power Breezer misting fan is a breeze. The misting fan conveniently runs off a generator (under 900W) and has easy universal controls. The misting fan has a 100-gallon water tank capacity, providing 4 to 5 days of continuous use.

It’s important to note that evaporative coolers do not offer the level of performance and comfort control associated with air conditioning. However, they still provide a good way to cool on a budget.

How Does Portable Cooling in a Tent Work?

Now that we’ve covered some of the party tent air conditioner options let’s discuss how the equipment performs. As you bring conditioned outdoor air into the tent, you will want to direct the air up or down to avoid blowing directly on individuals.

Cold air will fall and form a layer of comfort here before it is drawn back into the return air duct to be re-cooled. With this approach, smaller units distributed throughout the perimeter of the tent will be advantageous. Keeping the event cooling equipment outside the tent is preferable if possible. The area should be as sealed as possible to prevent cooling loss.

An alternative method is to pressurize the tent with no return ducts, which is a very common method to deliver even cooling distribution throughout the tent. The best approach will hinge on the size of the tent, conditions outside, and other factors.

Power Sources for An Air Conditioned Tent

You also will need to consider the available power supply for your tent with AC. Will you be drawing electricity from an adjacent building or home, and if so, what type of power?

A generator is often needed to support adequate tent cooling. Determine the length of electrical cable required to hook up the portable unit(s) to the power supply. The greater the length, the bigger the size needed to maintain voltage and current draw.

Event tip: Don’t forget cable ramps to hide the cables and prevent trip hazards. Diffusers should also be considered for ease of installation.

Have you ever found yourself planning the perfect event? Maybe a wedding or a large family reunion, or even a sporting event, or concert? One major concern is air conditioning. You want your guests to enjoy the event, and a comfortable temperature is required for this to happen. Whether the event is indoors, in a tented outdoor location, or in an open outdoor location, rental air conditioning units are a great solution. Here are four options for event air conditioning rentals that can help make your event perfect.
  1. Vertical HVAC Units - Vertical HVAC unit rentals can be used to provide air conditioning for indoor events as well as tented events as long as the tent is fully enclosed. Vertical HVAC rentals can clamp directly onto the sidewall of a tent, making these units appear to be part of the overall structure. Vertical air conditioning units have both cooling and heating features, and are ideal if your event has space limitations.
  2. Horizontal DX HVAC Units – Horizontal air conditioning rentals can be used for indoor events and fully enclosed tented events. Horizontal air conditioning rentals provide temperature control, offering both cooling and heating features to keep your guests comfortable for the entire event.
  3. Spot Coolers – Spot cooler rentals are very versatile and while they won’t cool the entirety of a large structure, they can be used to provide air conditioning to specific areas of your indoor event. Spot coolers are quiet and can be adjusted to fit your event’s temperature needs.
  4. Misting Fans – Misting fan rentals are ideal for providing cool air to open, outdoor spaces. Misting fans can cool your event without getting guests wet because the cool water vapor dissipates just a few feet away from the fan. They are ideal for outdoor events such as concerts and weddings, and outdoor patios or tented events that are not fully enclosed.


So, your big event venue is in need of additional heating and cooling or whatever else it takes to keep your guests comfortable! That might mean a rental air conditioning unit is exactly what you need, but that doesn’t mean that there's only one type or style. When it comes to air conditioning equipment there are additional varieties to consider. Here are some of the best options to keep your event running smoothly!
