Should a system be over-sized, it will use more power to run but never achieve its maximum efficiency. This means it will continue to run, wasting energy, and, increasing your utility costs. Why all of this is so important is it gives you a general idea of just how big a commercial heating and cooling unit you need to keep your business comfortable. So, a 6 ton commercial HVAC system will output 72,000 BTU’s in an hour. The average household HVAC unit ranges from 1 to 5 tons, however, units over 5 tons are generally considered commercial. If an HVAC system is undersized, there will be more hours per year when the plant is running fully loaded, and the system will not be able to hold indoor design conditions even on a design day, let alone any hotter days that is, temperatures in these air-conditioned spaces will rise. What this means is 1 BTU will heat or cool one pound of water by one degree Fahrenheit. A ton in the world of HVAC is the measurable ability to heat or cool. Of course, this isn’t the weight measurement associated with very large objects it isn’t 2,000 pounds.

Air conditioners, as you might know, are measured in tons. This can be done, in large part, by knowing what size commercial HVAC you need. While you certainly want to save money where you can, it’s very important to think long term. Some business owners make the mistake of buying a system based mostly on price.

When you need to purchase a new commercial heating and air unit for your business, you’re probably most concerned with the acquisition and installation costs.
