Old Colony came to my home this morning to look at our heating system which was not functioning properly. They sent two men who after 10 minutes of looking at the boiler decided it needed to be replaced, for $8000. We had another company come for a second opinion 3 hours later - they fixed the system in the same amount of time.

Tech told me he would be there at 8am the next day. I set my alarm to be up
before that. At 10 am I called to see where they were. He denied he said he would be there at 8 am and then said he called me and nobody answered. I was sitting by my phone the whole morning, no call was made. He was very rude and when I cancelled my appointment.

WARNING !! DO NOT TRUST THIS CONTRACTOR. On October 13, 2020 we signed a contract with Bill at Cox Old Colony, to install a Mitsubishi ductless AC/heat system, 2 units and condenser. We gave him a check for cost of all the equipment, "to purchase the units and condenser". He told me he ordered it immediately same day. I waited, ...I waited,... I called,.... months went by. Still no system.
So many promises to come but always a - NO SHOW. Phone call, after phone call. March 30,2021 after so many phone contacts he delivered only the 2 wall units and proceeded to ask for more money, thousands

Had a negative experience. Repaired furnace last November. Assured that the work was warranted 2 years. Paid cash and got receipt. Just shy of a year... had no heat. On the phone I was told it wasn’t covered under warrantee and they didn’t know when they could come out.
Did come out and was very reactive to me asking questions. Ended up leaving in his reactivity. He was accusing me strangely and it was very unexpected. I would not have trust in this company. It’s mutual as he said he would not do work on my property again.
