"We obtained 4 quotes for installing a new boiler and hot water heater. AllPhases was competitive with the quote and Carl was very responsive to our questions. He also had experience working with MassSaves so we will be getting some pretty large rebates (~4k). Ken, Elander, Henry, Fred and Caesar took out our 60 year old furnace and installed a high efficiency system that should meet our needs for years to come. They worked over 3 days to complete the job and left it cleaner than when they started. There was an error message on the boiler the night after the install and Elander/Henry came by early the next morning to fix it. They have come back 2 more times to troubleshoot and everything is working great. Ken and Elander have also answered other questions I've had about the system since the job was completed. I have no complaints and would highly recommend AllPhases Mechanical to family and friends."

"We have been using them for over 20 years.  They service our burner well and have provided great customer service.  I don't mind paying a little more for that service in a higher oil price on top of my repair contract price.   I just paid over $3.00 per gallon.  Many people I work with pay from $1.99 to $2.29 per gallon.  Many of them use full service companies.  The driver did not know how much the price would be until the invoice printed out from the printer in the truck.  That tells me they use different pricing for different customers.  I am paying an extra $200.00 per fill up.  I did call the company and they lowered the price a little to 2.69.  I will have to switch to another company unless they can adjust their pricing to be more competitive.

"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."
