Services
Air Conditioning Services
We make air conditioning service more convenient by providing installation, repair, and maintenance through a single experienced team. There is no need to arrange separate contractors for different cooling requirements. Large projects and minor service requests receive prompt attention. Our commitment to reasonable pricing and consistent availability helps customers manage their AC needs throughout the year.
Furnace Services
Our technicians perform furnace repairs and preventive maintenance tailored to different heating technologies. For oil systems, we clean burners, replace filters, and inspect fuel lines. Gas equipment receives heat exchanger, igniter, and leak checks, while electric furnaces require component and circuit inspections. We also provide professional installations and 24/7 emergency repair assistance for residential heating systems.
Heating Oil Delivery
Our family continues a longstanding tradition of delivering heating oil to residential customers at reasonable prices. We recognize that timely fuel deliveries and trustworthy service are important to homeowners. With nearly 80 years of local experience, we provide knowledgeable support and professional delivery operations. We work to ensure every customer receives consistent attention and dependable assistance.

Our family is a long time customer of John Weidman & Sons and will definitely continue to be a customer. On Saturday morning, we had no heat in the house and the outside temperature was well below freezing. At 6:00 am, I placed a call to the emergency service number where I reached Eric. He listened to my description of the situation and my concerns. In less than one hour, Eric arrived at the house. He evaluated the situation and quickly resolved what was, fortunately, not a major issue. Eric was prompt, competent, helpful, and pleasant. I would definitely recommend John Weidman & Sons.

I have been buying heating oil from Weidman's for 30 years, and the service has always been good. Deliveries usually arrive earlier than expected.

John Weidman and Sons has been delivering my oil and cleaning my furnace for the last 6 years. I couldn’t be happier with their timely, exceptional service. Most recently, Tad came out to give me a quote on a water heater and several other appliances. I appreciated his expertise and honest recommendations!

John Weidman & Sons have been SO great to work with! They have made everything incredibly easy in my previous experience working with them, and genuinely went above and beyond when delivering oil. I could not recommend this company enough for their stellar customer service, quick turnaround, and reliable team. Thank you for all you do!

John Weidman has been nothing but professional, helpful and kind. They are available when you need them and reasonably priced. I can’t say more about the prompt, competent and honest service I have received. Two Saturdays this year I had trouble with my boiler, and someone was able to come out the same day each time. I was also able to talk to an intelligent human on the phone who was respectful and gave me honest, helpful advice. Thank you to the customer service reps, drivers and technicians at John Weidman and Sons!!

We have dealt with John Weidman and Sons for many years. They are very knowledgeable, trust worthy and fair in pricing. We recently had our "worn out" furnace replaced. Paul Jr., Dave and Tad could not have been more helpful, professional, efficient and clean about their work. We will continue to have John Weidman and Sons as our #1 choice for HVAC work.

We.woke up to no heat and called John Weidman thinking we had ran out of oil. Two associates had spoken to me on different calls walking me through steps to try before they sent out a service person. We were able to get our heat running again. We have been doing business with John Weidman for 12 years and we are so grateful they were able to service us even after we moved. We not only appreciate their time, but their honesty!

One morning I woke up with no heat. Our landlord had oil already in the tank when we moved here a year ago. So we didn't have a oil co. I called them and told them my situation and told them what sauders said and they helped us out. They needed 24 hrs notice . but they knew we need oil right away. They also sent a technician to restart our furnace. So thankful for this company.

These are wonderful people. They go out of their way to serve and take care of their customers. Even during their colder busy season they work hard to make sure everyone is warm. When I call to set up an appointment it is also like catching up with friends. The business is family operated and shows. Thank you!

We have had the pleasure of using John Weidman & Sons for both a property we were living in and a business endeavor. RMM Interiors utilized JW & Sons for a business property due to the exceptional service we were receiving at our home location. We appreciate their timely service, professionalism and fair pricing. They get the job done right and are a family-owned business...what more could you ask for!
Sincerely,
RMM Interiors
