Do you need to purchase a new commercial HVAC unit for your business? If you do, then we’re guessing that you’re probably most concerned with the acquisition and installation cost and that’s where you’ll probably go wrong. Some business owners make the mistake of buying a system based mostly on the price-- don’t follow the same mistake! While you really want to save money where you can, you must think long term. You can do it by considering not only the cost of the unit but also by knowing the size of the commercial HVAC that you need so you would know how efficient it can be.
Figuring out how to properly size your HVAC unit is even more vital as knowing what grease duct panel you need. This first step is vital for your business. If your HVAC unit is not sized properly, you could be facing issues such as running non-stop to running in short bursts constantly throughout the day, insufficient moisture removal, to inconsistent temperatures throughout your building, and more importantly, a very high energy bill, all year long.
Fear not, however. This article will tell you about sizing your commercial HVAC unit.
What Commercial HVAC Unit Size Do You Need?
For household HVAC units, the average size ranges from 1 to 5 tons. Once a unit is over 5 tons, it is already generally considered commercial. This is important because it will give you a general idea of just how big a commercial HVAC unit should be to keep your business comfortable. If your unit is too small, you will have to use more energy to try and reach the programmed temperature and this might not happen depending on the conditions. In short, the unit will continue to run, thus wasting energy and increasing your utility costs. On the other hand, if your unit is oversized, it will have to use more power to run but never achieve maximum efficiency. This is the reason why selecting the right-sized unit is imperative. To know for sure what size of commercial heating and air conditioning system you need for your business, it is advisable to contact an experienced licensed technician.
Steps To Properly Size Your HVAC Unit
To know the proper size for your HVAC unit, you need to determine how many BTUs are required. BTU measurement describes the size of the unit or units in tons. British Thermal Unit, or BTU, is the amount of heat that is needed to heat 1 pound of water one degree Fahrenheit. Although BTUs are important, most of the larger air conditioning units are now rated in tons.
1st Step: You have to calculate the square footage of the area that needs to be cooled. Identify if the office space will be divided into zones and cooled by separate air conditioning units and keep the measurements separate.
2nd Step: Multiply the square footage for each area by 25.
3rd Step: Add 400 for each person who works in the area.
4th Step: Lastly, add 1,000 for each window.
5th Step: The number that you gained from the 1st step to the 4th represents the minimum BTUs that the air conditioning unit should provide.
