Schraer installed a steam humidifier for our Geothermal water furnace. Chuck, who the service rep gave us a competitive quote on Monday and the unit was install by Friday. Extremely professional individual who took extra time and care to get the job completed. He was knowledgeable about geothermal and did a great job educating us with regard to our new steam humidifier. Highly Recommend this company and this individual!
