It took the better part of three days with a two man team and with a number of other professionals from SILA coming in and out to help solve challenges (such as handling the exhaust). It was expensive and it remains to be seen whether the efficiency savings will prove to be cost effective. Given the complexity of the system and the use of radiators that were originally used for steam, it is not really advisable to adjust the temperature manually or via a programmed thermostat. Changes in temperature take a long time. But they did a very through job and it's an amazingly beautiful installation.
Description of Work: Installation of a high tech Bosch Greenstar FS condensing boiler to drive a forced hot water radiator system in a single family house with many complications (with electric baseboard heat in one room on second floor and a hot box heater running of the old boiler in the finished basement).

I did not hit it off with the service inspector. I like details explained to me About any issues with HVAC, service man was not interested in explaining to a “female”. Also, I think they could do better on offering helpful services, I don’t need to be helping them with the service they are providing me such as turning Ac/ heat on and off for them. They should be able to provide a better service for filters to me at a reasonable price on a regular basis. My old company would Have them sent to me prior to their visit. All in all Silva was just to busy to Engage the client and offer a step to save them time for a reasonable price. “D” score from me.

The original appointment was scheduled from 8am to 12pm for a 4 hour window. Sila called at 11:30am saying that the technician was running late and will arrive close to 12pm which was the end of the service window. My entire morning was wasted waiting for Sila. Anyways, had the appointment rescheduled to Nov 3rd. On Nov 3rd they called and asked to come earlier than the scheduled window of 12-3pm. Since the earlier time wouldnt work for me they did something on their end and the team arrived during the service window. Things went very smooth from that point on. Dave was very experienced and skilled with servicing the furnace. Very courteous, professional and helpful. He took the time to thoroughly service the furnace without any shortcuts or bad-aid type work. Would highly recommend Dave from Sila.

Thanks for leaving us a review on Angie's List. I'm sorry you feel the way you do about our maintenance's, more specifically the visit to your home in North Chelmsford. Our Technicians are highly trained, highly skilled and do a very thorough job on every maintenance they perform, so I would have to disagree with you on that. We apologize for any inconvenience we may have caused you but we certainly stand behind our Technicians and the integrity they hold as Sila Technicians. Best, Sila Heating and Air Conditioning

John arrived at the scheduled time, was professional, pleasant, knowledgeable, and explained his findings, and work that will likely be needed in the not too distant future. He also provided helpful information regarding the type of filter to use. As a result of my positive experience during this visit, I signed a maintenance contract for the year for the furnace and central AC. It was a pleasure to have done business with Sila.

His attentiveness to detail was excellent, and I appreciated his honest advice. I would certainly recommend him to my network. The person who assisted with scheduling my service was also incredibly helpful. The purchase of the coupon on Angie's list was seamlessly integrated with their scheduling system, and they were able to come out in a reasonable amount of time. The customer service overall was fantastic.

I purchased a special deal on Angie’s list. They dragged out the process until the 30 day full refund time had expired. I had to call them repeatedly ( spoke with Jake, Wes, and a woman whose name I forget) and provide the same information at least three times before they even scheduled the work visit. Then they wanted to charge extra on the day of the job as I have more steps than they expected. So we postponed while I considered the extra charge. Then I contacted them to agree to pay the extra and to reschedule the work, and they never replied. I Purchased the deal on May 5, 2017, and they came to do the work on the 14th of July 2017, when I postponed the work. . They never returned my email to reschedule. At that point I gave up and went to big blue plumbing who were awesome. I emailed them in distress from Australia, and they replaced my water heater that very same day.
