@hvacknowitall: Quality... I recently worked on site with Foundry Heat Pumps and was blown away by their quality of workmanship. A 2.5 Fujitsu AIRSTAGE XLTH was installed replacing a traditional AC and furnace with a 5kw resistive heat kit. The XLTH will heat down to -15⁰F While the XLTH+ will heat down to -22⁰F #hvac #heatpumpservice #heatpumpinstallation #heatpumpinstall #hvacinstaller
