"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!"

"This company has been awesome. I am a Worcester resident and have no clue about heating systems. David Clay and his team came out to look at my boiler. It was not firing. Winter is fast approaching. David provided a free estimate and also encouraged me to look at quotes from other competitors. I did. And his pricing was best aligned with my budget. His quality of work is amazing. David and his technicians fielded all my questions- I had many. Their customer service is amazing as they had all the patience and courtesy to educate me about the work and boiler systems. My experience as a customer is that Clay Plumbing Heating offers the best quality, professional craftsmanship, best client service, and at the best rates."

"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."

"Came in to install a new faucet and trap in the bathroom. On time, polite, and courteous. There was a slight leak in one of the flex lines. Came back the next day and rectified the problem. A good experience."

"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"

"I originally called the company that did my regular maintenance less than a year ago. They told me they couldn't send someone out for 3 days! This in the middle of a cold snap. When I called Rodenhiser, they were able to send someone the next day. While they were not able to completely fix the problem right away - a part was needed - they were able to restore heat while we waited for the part. They came back in a few days and repaired the boiler zone controller."

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."

Install Boiler questions, answered by experts

Most installations take 2-5 days, including old system removal and setup.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.
