“Today Gary came out and did the annual maintenance on my heating and A/C unit. He took pictures of everything and showed me my blower fan was dirty. He quickly cleaned it to look like new! 5 stars for him!”
“Schaef Air was a life savor for our family. We had HVAC issues in our upstairs system. They scheduled an appointment very quickly and came out in a very timely manner. The technicians came out and were extremely professional and knowledgeable. A few months after they came out we had them come out a second time and again, they were awesome. I will be recommending them to anyone!”
“We have been using Schaef Air for many years of repairs, installs and semi-annual maintenance. Recently we had them install a 3-head ductless heat pump system. The staff’s professionalism and quality of work was and always has been top notch. I would highly recommend Schaef Air for any of your HVAC needs.”
