When it comes to HVAC services

What our customers are saying:

Pleased with new furnace, A/C and duct work

We were impressed with the crew of three young men who were polite and professional. We want to especially thank Angel who brought to our attention a few other details that could be incorporated to improve our duct work and enhance our new central AC. We appreciated his initiative and his professionalism.

Excellent job on boiler installation

Last week, Daniels Oil installed a new steam boiler. The large radiators got hot all the way through for the first time in more than two years. I wish to thank Peter, Joe, Jim, Rob and Rick for there professionalism, thoroughness and expertise. They were friendly and did an excellent job at installing the boiler and explaining how to operate it. I can’t imagine that I could have been happier or had better results with any other company in the area.

Pipe gurgling problem solved

A big Thank You to Daniels staffer, Rick O. who solved my pipe gurgling problems. He was very professional and knowledgeable. He discussed several alternatives and the possible cost of each. He is my hero and he turned a less than good situation into a reasonable solution.

I have been dealing with Danels Oil for a very long time. They are a  great group of people who are very polite and professional!

A/C problems solved in extreme heat

During the heat wave this past week, I needed service on our AC system. I was provided excellent service by Bob B. He worked under extreme heat in our attic. He attitude was very professional, customer oriented and he was an excellent reflection of Daniels Oil Company. I was extremely very happy and pleased with the service.

Impressed by service professionalism

We recently purchased and had installed our new propane stove. As new Daniels customers, we were very impressed and satisfied with the quality, excellent service and professional competence demonstrated by the Daniels Team. We look forward to a long relationship with Daniels. Thank you for a job well done.

Fair, Honest and Courteous Service is Applauded

We feel that Daniels has always treated us fairly, honestly and courteously. That is VERY important to us.

My husband and I applaud your good judgement and training of your service technicians. We just had our furnace cleaned for the year and your serviceman (I’m sorry I didn’t get his name) did an excellent job. He completely broke down the whole furnace and cleaned it thoroughly from top to bottom. He cleaned up afterwards and, upon my inquiry, suggested the ideal replacement heating system.
