We at Arctic Heat Pumps provide manual J design service to determine the heating and cooling design load. Without a heating or cooling design load, it’s quite difficult to size any heating system accurately including gas, electric, or heat pump systems. We use the industry-best Manual J Calculation software to determine the heating and cooling load. If you want to properly size any heating cooling equipment from any manufacturer, give us a call anytime at +1 (866) 800-8123.
