To keep your employees comfortable and avoid high utility bills, you should choose an HVAC system that’s the right size for your Plano, Texas, business. Commercial HVAC load calculations can help any business save energy and money. Here’s some more information about load calculations and why they’re important.

Finding the Best HVAC System for Your Business

If your system is too small, your building will have warm or chilly spots. Heaters and air conditioners that are too large wear, stop and start more frequently, wearing out faster and costing more than correctly sized models. They also don’t run long enough to dehumidify the air as well, also causing temperature fluctuations. Since large systems turn on and off frequently, they also make more noise. An experienced HVAC professional can help you find the best, most efficient system for your business.

Avoiding Estimates

Many contractors estimate sizes for HVAC systems by adding 1 ton of heating and cooling capacity for every 600 square feet. However, many newer homes and businesses have lots of insulation, making the correct capacity closer to 1,000 square feet per ton. If your contractor uses an estimate or rule of thumb, you could end up with an oversized HVAC system. A heater and air conditioner that’s the right size should run constantly during the coldest and the hottest days of the year. 

Manual J

The Air Conditioning Contractor’s Association of America, or ACCA, writes Manual J to help professionals size HVAC equipment correctly. Many contractors use a computer program to make the calculations easier. Manual J load calculations take into account the size of your building, the amount of insulation, the number of windows and heat-producing appliances, the amount of shade outside, the average number of occupants, the average outdoor temperatures in your area, and more.

For a perfectly sized system, choose a contractor that uses Manual J, like Samm’s Heating and Air Conditioning. We can help you install, maintain, and repair a variety of commercial HVAC equipment. Call us anytime at (214) 251-4438 for excellent service.
