"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

"JT called and asked if he could come earlier than expected, which was perfect for me. He was extremely thorough reviewing our electrical system and the finished product of the work he did (installing a new 220v line for an outdoor hot tub) was clean and efficient. He was a joy to meet and speak to, incredibly nice guy. Price was reasonable for the work. I would 100% recommend JT and Cotti-Johnson again!"

"It went very smoothly. There was one minor hiccup that wasn't discovered until after 9pm on the evening of the installation, but we called the 24-hour service line and within 20 minutes, there was a tech back at our house to fix the issue. I would contract H L Bowman to do work for us again in a heartbeat."

"The installers seemed to be quite knowledgeable and professional. They concentrated on doing the lob, were thorough and pleasant. They answered all questions to my satisfaction. Everything was done on time and all equipment and workers arrived on schedule. They were careful not to create any excess dust during the installation and did a good job of cleaning up when the work was done. In spite of the attic temperature being well over 80 degrees, they worked continuously and finished on schedule. I would recommend Airco Home Comfort Services to anyone who is looking for a high quality, professional job. They demonstrated the technical knowledge and engineering capabilities to evaluate the job and to select the right equipment for my requirements, more so than several other providers were able to do. I was not looking for the least expensive job, but for the best engineering capabilities for a fairly large house with a good sized, north facing sun room and many windows.

"Hello, Yellow Dog Home Services was phenomenal! Jeffrey was able to come the same day, complete an assessment, and define the next steps for the installation of a new hot water heater the following day. He is very personable, professional, knowledgeable and affordable. Yellow Dog is now saved in my iPhone for future project needs! Richard"

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

Customers say: Super punctual

"I purchased a new dishwasher and installed it myself. Well, not completely. I ran into some difficulties with the hot water supply line. I called Milltown on a Sunday hoping to get on the list for Monday. Amazingly I got a call on Sunday evening. They came on Monday and not only installed the hot water connection, but also replaced an old leaky hot water shut off. This was in an almost impossible position to access, but he did it in a few minutes. Since he was there I asked him if he could repair a troublesome flush mechanism on one of my toilets. I had other plumbers work on this with limited results. He diagnosed the problem quickly and I'm happy to say it continues to work very well."

"Manny and Alex installed a Toilevator for us, which is a platform that raises the toilet up 3.5". They did a great job. They were on time, worked steadily, and completed the job quickly. Everything was left neat and clean. They were very courteous and professional. I would definitely recommend Akian Plumbing."

Install Boiler questions, answered by experts

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

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.
