Kevin from Sheller Oil did a great job working on my A/C unit.

Sheller Oil is an absolutely superb company. I just moved to Malvern and needed my propane tank filled. They were there the next day as promised. Best pricing in the area, no extra fees, and very simple and straight-forward billing. A week later I scheduled a tune-up for my HVAC system without realizing that the previous owner had it serviced before leaving. The technician discovered this, told my wife, and had the work order cancelled with no charge!!! Blew my mind. Incredible integrity and honesty, which is hard to come by these days. Well, Steve and his crew just earned a long-term customer. Thanks guys!
