"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"Very please with the install. Vin was very professional and applied due diligence to the project. His oversight and instruction provided the reinsurance that needed. I requested four heating and AC vendors to provide proposals. Tyler was most responsive to my questions and offered me alternatives along with helpful suggestions. My next project is my boiler. I will be turning them in the future."

"Prompt, efficient service --- Technically knows gas furnace products --- More importantly knows the economics of keeping up with repairs on a 30 year old unit vs going with a new unit --- Not a sales pitch -- just facts ---- Went new and the cost including nicely done installing was much lower than I originally thought it would be .

"Furnace was not operating because the company's automatic delivery system ran me out of oil.
Technician showed up promptly and got the furnace operating but could not get heat into the house. Had to reschedule to have zone valves replaced. Technician show up late and didn't have the required parts. Had to reschedule again.
The third technician showed up on time with all the correct parts and worked most of the day to get the system operating properly.
He was completely knowledgeable and very conciencious that everything was working correctly.

Install Boiler questions, answered by experts

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.
