"We've used this service twice - both time to install split level units. We couldn't be more pleased with the quality of service and the technician. Steve was on time (a rearity for contractors), the job was completed in a timely manner, he clean up after himself and best of all the units work like a charm. Unlike most contractors that grab the money and disappear Steve has checked in with us to confirm that the units are still working. Excellent customer service indeed!"
