We just wanted to say thank you for the excellent job the technician Larry O. provided to us during the boiler maintenance visit on 9/22/25. Larry is a true professional. He took his time going thru all of the equipment, checking, cleaning and replacing necessary filters. Also, his positive attitude, pleasant personality, dedication and professionalism made the entire process easy and stress-free for us. Definitely, we'll ask for him next time. Thank you, Larry O.!
Just had an annual oil burner maintenance with larry and he did a good job. I'll recommend his service. Definitely, I'll ask for him the next time. Has a pleasant personality, respectful and very meticulous professionally..
This is the best Fuel Oil Company ever. They are caring, respectful, prompt and get the job done properly. I have been a customer for many, many years and they have never, ever let me down.
I wouldn't recommend this company to my worst enemy. Bunch of phony guys making up baloney. What's a family business without value or morals. Do not get oil from them use another company.
