Leffler is a great company. They're my oil supplier as I have oil heat and hot water heating. They're affordable and provide excellent service.

Leffler replaced our central air with a new and upgraded outdoor compressor unit. The old unit was too loud. The new one is so much quieter; what a difference! Matt in sales was very knowledgeable. The techs Barry and Steve did a high quality job with professionalism. We are more than pleased
