“The Best Customer Service Experience I have ever had and I have been in the customer service business for 44 years. We recently purchased a cabin in Innsbrook and had a problem with the AC. Our real-estate agent recommended Schraer HVAC. They dispatched a technician within 48 hours and he fixed the problem immediately. Since it was a 40-year old unit we decided to replace it. They were able to schedule the replacement within a week and based on our schedule. At the last minute we had a family emergency and we had to coordinate the installation without us present. Needless to say, the install and communications were seamless. The level of communications, understanding, courtesy, respect, professionalism and friendliness of each of the members of the their team was outstanding! A Special Thanks to Dan (technician), Bill (pre-install manager), Julie and Michaela (office – a real joy to work with) and the two technicians (who I never met) who did a great job of installing and cleanup. We appreciate all of you!”
