We at Arctic Heat Pumps provide manual J design service to determine the heating and cooling design load. Without heating or cooling design load, it’s quite difficult to size any heating system accurately including gas, electric or heat pump system. 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.
