What Does “Tons” Mean for My Commercial Air Conditioning?

Monday, April 26th, 2021

When you hear or read about commercial air conditioning systems, you’ll often come across the word tons used to refer to equipment. For example, light commercial air conditioning service, which is what our company provides, refers to equipment that is 25 tons and under. You might think this refers to how much the equipment weighs, but that’s not the case. 

Tons or tonnage instead refers to the amount of cooling power an air conditioning unit delivers. We’d like to help you better understand this terminology—it will make it easier for you to know what work is being done for your commercial facility when you have new equipment installed. Our technicians are always willing to provide you with any information you may need.

What AC Tonnage Means

A ton is the cooling capacity of an air conditioning system. One cooling ton is equal to 12,000 BTUs (British Thermal Units) of heat removed per hour. Since most commercial systems have more than 5 ton cooling capacity, you can see why using this measurement is convenient: a 15 ton commercial AC removes 180,000 BTUs per hour. It’s much easier to compress that down to a convenient “15 tons.” 

But why is this measurement called tons in the first place? The reason is that 12,000 BTUs is the amount of heat needed to melt one ton of ice at 32°F over 24 hours. This is an old measurement that was set as the industry standard in 1903. 

Matching AC Tonnage to a Building

Now that you know what tons means for an air conditioning system (probably more than you ever wanted to know), the next question is: “How many tons of cooling do I need for my facility?” That’s an important question, and it’s one that you need commercial HVAC professionals to answer. 

Tonnage must be carefully matched to a facility. An AC unit cannot be undersized, or else it will not provide sufficient cooling. But it can’t be oversized either because this leads to a malfunction called short-cycling, where the AC turns on and off rapidly rather than completing a full cooling cycle. 

Finding the right tonnage of air conditioning system for a building requires professionals to size the AC with a load calculation. A load calculation factors in various criteria about the building, such as the equipment inside it, the number of windows and their sun exposure, the heat given off by lights, and the standard number of people indoors, and comes up with a tonnage amount for an AC to provide. Modular rooftop air conditioning units allow for easy adding of units to meet the tonnage amount.

All of this also applies to packaged heat pump systems, which work as both heating and cooling systems—it’s a general term that can be applied to all refrigerant systems.

Yes, It’s Time to Consider Commercial AC Maintenance

Monday, February 15th, 2021

It’s February, and that means it’s still winter. Temperatures have dipped down into the 30s during the day, and you head to your business each day with a heavy coat to keep you warm. So why are we talking about air conditioning at a time like this?

Because preparing the air conditioning equipment in your business is critical as spring approaches. Having AC maintenance done when it’s already hot is, well, like closing the barn doors after the horses have escaped, if you don’t mind us using the oldest of clichés. Prevention through preparation is what regular commercial HVAC maintenance is all about, and mid-to-later February is a good time to start those plans. After all, spring starts next month!

Making Commercial HVAC Upgrades Will Help Your Bottom Line

Monday, November 9th, 2020

When you manage a business, you keep a close tab on your budget. That is an essential part of running any company: you want to know about revenue and overhead, and where you can make improvements to raise the first while reducing unwanted spikes in the second.

One place where you may be spending more on overhead and not even know it is on the HVAC system. Any type of work space, business office, or facility uses an HVAC system. It may be primarily for the comfort of people in the facility, or it may be necessary for protecting equipment and process. But it’s vital—and it may be costing you too much because you have outdated equipment or equipment that needs upgrades.

Why Server Room Cooling Is a Special Air Conditioning Case

Monday, August 31st, 2020

Almost all businesses have server rooms or computer rooms of some type: this space is a basic part of data and communication management. These rooms have special requirements when it comes to cooling. It doesn’t work to simply have a server room connected to the standard central air conditioning system of the rest of the building, since a central AC is primarily to provide comfort to employees, customers, clients, tenants, or whoever else is in the space. Server room cooling is designed to protect precision, heat-producing equipment.

If you are looking for proper server room cooling in Everett, WA, then you probably already know that simply keeping the server room door open or putting a standing fan in there won’t do the job. Protecting vital data and equipment takes special service, and our certified light-commercial specialists can handle the job of setting up your server room cooling.
