They replaced my Furnace and Central Air Conditioning in just a day and a half. They also threw in a new faucet installation at no extra charge. Everything with these guys is about making the customer happy. I will definitely use them again.

We finished renovations on half of the bathroom before we realized we were going to need to make some changes to the plumbing. We called Cox and they came out to give us an assessment.

I had a leakage in my kitchen sink so I called Cox's Old Colony and within 30 minutes they arrived. The price was cool and I must say they are very professional with their services. Now my leakage is fixed and I am a happy customer.

Old Colony has the best Customer Service hands down; They made sure I knew the costs and fees before proceeding with the job. They were polite and very attentive and even spent extra time making sure everything worked properly.

I had a good experience with Cox's Old Colony. They installed a complete heating and AC system in our home (2-furnaces and 2-AC). The crew was very professional, left my house clean every night and let me know when they will arrive the next day.
