"They came to my home showed me what needed to be done and they went and got the water heater. When they came back a short time later they had the tank and installed it in an hour with new pipes and a new shout off that I can do."

"Our experience with All Phases Mechanical has been excellent. On the first occasion we used APM, we lost heat during a cold snap in the middle of winter. We called in the morning and a technician arrived that afternoon and quickly determined that not only was our 20 year old furnace in need of expensive repairs (which a friend of ours in the construction industry validated), but continuing to run it would potentially result in a carbon monoxide hazard to my family. Carl gave us clear options and helped us understand benefits (rebates, no interest loans, etc.) that are available from the state to assist families in our predicament. We decided to move forward with a new furnace and Carl's team installed it the next day. On the second occasion, APM helped us our central air conditioning system. Again, Carl sent a technician who arrived promptly the same day, who determined that the air conditioning system was fine but it wasn't working properly due to faulty wiring. He quickly fixed it and was on his way - all at no charge. I can't say enough about All Phases Mechanical. If you're looking for a local company that cares about its customers (and understands that heating and cooking problems need to be addressed quickly), All Phase Mechanical is the company you should use."

"All three jobs went great. For the water heater replacement Lewis came to my house at a convenient time for me, removed the heater changed out the rotted pipes and installed a new one with warranty. The price was great too. This job was time sensitive and he made me a priority to get it done. For the bathroom tub drain unclog he was very professional and did a great job. My garbage disposal was leaking and I came home to a pool of water in my cabinet and on the floor. Lewis came out quickly to resolve the issue for me. He replaced everything under the sink and showed me what he was doing each step of the way. I think that he is a great plumber if you want to get quality work and learn about each job too."

I truly struggle with this review.  In my heart-of-hearts, I not only want to give AGM an outstanding review, but for one fatal flaw.

So, my furnace was on the fritz.  At nearly 30 years old, it was time to be replaced.  I had several quotes, and AGM was competitive, though not the lowest.  They were my oil company at the time, and I?ve been very happy with my 2+ years of delivery and service, so I went  back to them, and they worked with me on the price.  They were also very patient as I went through MassSave to obtain a 0% 7 year HEAT Loan.  Since more than my furnace was old, I replaced my Furnace and indirect water heater (both with a System 2000) and oil tank.

On the day of delivery, AGM came on-time and got right to work.  They seemed surprised by the disarray of my zone design.  My house is on 5 zones, and the piping was confusing.  It was clear to me they were not happy with the allotted time to do the job ? or with the job itself.  They were particularly upset about 2 zone valves that were in difficult to reach situations.  They called out the technician who quoted me, who insisted he did not mean for them to be replaced.  I was notified that they would not replace them, but would bypass them ? and I could have them replaced ? potentially rezoned ? at a future date.  I was irate, but also in a difficult spot, considering my furnace was on the fritz.

They completed the installation in the time allotted, and the system is warm, quiet, and efficient.  Still, like buying a new car that arrives with a large dent, I feel cheated.  I hoped that someone ? anyone ? from AGM would follow up with me to rate my satisfaction.  No such luck.  I don?t know whether to be enthralled or irate.  I was told that the bypassed zones will have no impact, other than a small loss in efficiency? but, then, why did I pay for one of the most efficient boilers on the market?

I hope that AGM will follow up with me, and will help me make this right.  I have been exceedingly happy through the years, but I don?t feel this situation was handled in a fair manner.  I would like to come away from this trusting that my system operates efficiency and thoroughness that I paid for.  When I am satisfied this is the case, I will adjust my rating accordingly.
In summary: they were very professional, they were punctual, and stayed late to finish the job on-time, they worked with us on the price and were patient while we got the financing in place.  But for the zone valve issue - and the lack of follow-up on satisfaction - we were very pleased. 


*UPDATE 1: Oh, the power of Angie's List!  Atlas Glen-Mor saw my review, and reached out.  They've agreed to complete the install, and we've made an appointment.  While I do wish they'd have followed up with me regarding my satisfaction proactively, I credit them for monitoring reviews and responding accordingly.  I've tentatively upgraded my overall score to a "C" pending the completion of the project. UPDATE 2: AGM made it right! The company still seems to be reactive, as I had to follow-up multiple times to schedule the appointment, but it's a minor point in the grand scheme. Thank you, Angie's List, for giving me a voice and a forum, and thank you AGM for listening and rectifying my problem!"
