Load Calculations - They Really Make A Difference
Every week I meet people who are looking to upgrade their old cooling and heating systems. Many are getting multiple bids and I'm amazed at how some contractors are still "guessing" what size unit to offer. It is clear they are clueless to the guidelines that are used for today's homes. A full load calculation should be required by the home owner as well as any commercial client. Department of Energy, EnergyStar and consumer advocacy groups all recommend a load calculation and warn the consumer of contractors using the old "rule of thumb" of estimating the tonnage of cooling based on square feet of space. If your business, school, or church is looking to upgrade their HVAC equipment, have one of our mechanical engineers ensure you're installing the right equipment. It doesn't take a lot of time and it's well worth the investment. It will save you thousands of dollars in utility costs, unneeded repairs, and maybe in equipment costs. Give us a call. 314.664.3011.

Angela,
I was at a job last week and the customer had a 5-ton system and a 1l.5-ton system. Every contractor quoted the same size.
After running a load calculation I determined the correct size was 2-ton and 4-ton. We were the only contractors quoting the correct size.
Thanks
Hoffmann Brothers Heating and Air Conditioning is a great company and gives great advice
Evaluating the heat loss and heat gain is critical to selecting the proper unit.
