"Bottom line we are very satisfied. Here's the whole story:
The weather on Cape Cod has changed in the 40+ years since the house was built and air conditioning --which we would never have considered in the past--now seems like more of a necessity. The house has a lot of glass sliding doors, very little wall space, no attic, and no crawl spaces. We called in a few people, including Carl Tucci of All Phases to provide ideas and estimates.
Carl was very responsive and came across as highly experienced. He suggested two ductless split units and provided confidence that they would be sufficient to get the job done. Other contractors suggested more expansive and comprehensive solutions that were beyond our budget and would have caused more disruption than we wanted.
After agreeing on the approach with Carl we met with his installers. They came up with a clever way to fit one of the units above the laundry room door where it did not appear there was adequate head space. Basically they shortened the door to make room for the unit. This allowed us to get the air flowing down the hall, which we wanted and reduced the disruption to the living space from the installation.
We were confident enough in All Phases that we agreed to have them do the work in the offseason when we were not around. They emailed me photos of the installation as they performed it.
When we came back at the start of the summer the units weren't working properly. I contacted Carl and he got right back to me. He sent a technician to inspect and repair the units and they have been running great ever since.
The work is neat and professional. I recommend All Phases wholeheartedly.

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!"

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."
