Recent installation of 98% efficient Daikin HVAC complete system, perhaps complicated by my impatience with unfriendly internet technology from the manufacturer, was overall totally professional, cordially patient with my digital impatience, and fully up to Kellermeier long-standing excellence in every aspect of their fulfilling my order and installation. I wholeheartedly recommend Kellermeier Heating and Plumbing of Haskins, Ohio for all residential and commercial excellence over a large service area of northwest Ohio. Kellermeier staff have faultlessly attended to my residential HVAC and plumbing needs and emergencies for the past 48 years. Period! Full stop.
