We have been with Leffler since 2005. When we first started with Leffler, we signed up to pay a little extra to have an extended service warranty. The extra money has been worth it. Best of all, Leffler has always sent us service technicians who have been extremely professional. Be sure to request the best service technician at Leffler, Thalonia S, number 886.
