We wanted to have our ducts sealed and wanted to have the best company do the work. Only a handful of companies provide this service, and as part of our due diligence we interviewed and obtained quotes from Safety King and others. By comparison, Safety King stood head and shoulders above the rest, and their service was clearly the best in the business. Scheduling was easy and quick, and we received a phone call confirming the appointment the day before. The tech showed up on time, was extraordinarily polite and professional. Unlike some of the others there was no high pressure sales pitch, just a complete explanation of the services and the price. Their follow up was excellent as well. Based on my excellent experience I now recommend them to my family and friends.
