"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!"

"I called first thing in the morning on June 30th, as I had been without hot water since the previous Friday night. (Good thing it wasn't winter!) They not only came out within an hour, they secured a new unit and installed it the same day! That included emptying the old unit, removing it and installing the new one. The job was done by mid-afternoon.
They gave me a quote over the phone, and billed me the same amount. I was very pleased.
Last summer they installed a new central air unit for me, did a great job then as well. I just hope the furnace isn't going to go next! But if it does, I will know who to call.

"Joe and his crew did an excellent job installing new boiler and indirect hot water system. I made the decision to convert to gas and replace my 21 year old oil fired boiler. Everything went along smoothly and professionally. Joe kept me informed every step of the process and job was completed on time. I would definitely recommend."

"Outstanding service. I called because my boiler was leaking and the after hours technician responded within 30 minutes of our call. Our coil plate and gasket were rotted and bolts had snapped and we decided that we would replace the boiler because ours was 16 years old. We spoke with the owner and sales manager the following morning and were told that they would be happy to replace the boiler if that is what we wanted to do but they felt our boiler could be repaired at a fraction of the cost and no where near the end of it's usable life. So we decided to go for the repair and they were right, it worked like a charm! So instead of a $9,000 boiler and indirect replacement, we spent $472 and my boiler was up and running the next day. We have used Advanced Mechanical Services for our conversion from oil to natural gas and for our air conditioning installation. They have always been very professional, courteous, prompt and their pricing has always been competitive. I would highly recommend them."

"Furnace boiler would not start. Appointment was available the next day. Eric diagnosed faulty gas valve. Part was back ordered so took extra days. He replaced gas valve and furnace started but it did not start the next cold day. Turned out he should also have replaced the thermocouple. He came the same day when I called and was able to complete the repair at no additional charge. They stood behind their work and are a high quality firm but repair in one visit would have been better. Eric was very pleasant and professional and readily acknowledged his misjudgment."

"This was my first time using Omni Mechanical and I am very pleased in their service of my oil fired boiler. I had recently purchased my home and had very little knowledge of any prior maintenance of the boiler. Other than knowing it’s an older unit I didn’t know what to expect of the internal components when it was opened up and inspected. The techs were nice enough to let me observe as they were opening up the unit and exposed the internals. So I could see for myself what they were talking about and physically see the condition. They walked me through what they were doing every step of the way. Taking the time to explain parts they needed to change and actually showing me the condition of the older parts as they were changing them. After all work was complete. Everything was left very neat and clean. This by far has been one of my most pleasant encounters with a contractor. I will definitely strongly consider them in the future for any work I need."

"Jeremy and his team gave me the best contractor experience I've ever had. He listened to what I wanted, provided a fair quote for a central A/C replacement (air handler and condenser), and never pressured me or tried to upsell. In passing, he mentioned a heat pump option for the shoulder months to reduce oil use, but that was it. After doing my own research, I called him back with questions, and he took the time to walk through the pros and cons honestly. There was no sales pitch, I actually asked for a quote heat pump quote too, because I saw the benefits myself. I ultimately chose the heat pump and appreciate that Jeremy gave me the information needed to make an informed decision. His crew was fantastic, friendly, professional, and thorough. They removed the old system and completed prep work on day one, then finished the install on day two and walked me through everything. Great communication, great pricing, great workmanship. I highly recommend Jeremy and his team!"

"Precise HVAC was wonderful. I actually was going to get more quotes but after working with their salesperson I decided to not even bother. They answered all my questions and made suggestions for things I didn't know about. I'm not even sure I care if I got a better quote or not. With Precise I know that they cross the t's and dotted the eyes and I don't have to worry about missing something."

Install Boiler questions, answered by experts

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.
