"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

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.
