G&G Mechanical is a Wakefield HVAC and plumbing contractor that, per its own site, launched in 2000 and does residential and commercial heating, cooling, boiler and plumbing work. Google shows 4.7 stars from 18 ratings. A March 2023 Google reviewer had a new heat pump system installed and said everyone from sales to the installers was responsive. In a May 2025 review, a landlord said G&G arrived the morning after a tenant reported a leaking water tank and recommended a new boiler and water tank; they rated sales and installation highly but said management refused to let them pay the $13k job's balance within 30 days, and called the owner greedy, with no compassion for a repeat customer. A February 2026 reviewer who had used G&G for tune-ups for several years called the office very responsive. In June 2026, a Google reviewer said the company was not accepting new customers and declined to share even its standard diagnostic fee.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from G&G Mechanical, Inc.. Use it to sanity-check bids, then get the real number in writing.

They were not accepting new customers and refused to offer a simple information at all, even as a courtesy. I asked if they could at least share their standard service/diagnostic fee so I had a baseline, but they declined.
We’ve had our tune ups and service with G&G for several years and I’m so glad I found them. The front office is very responsive and the HVAC staff have all been great. Friendly and knowledgeable. They came to replace a part today and the system still was not working. He took the time to determine the problem wrong part for this model at time of installation. Our unit WAS NOT installed by G and G. He took the time to explain, create a temporary solve, and will be back with tge correct part. Highly recommend G&G!
I rent my condo in Cambridge. Tenant called to let me know water tank is leaking. GG was there the next morning and said I need a new boiler and water tank. The sales person was also an experienced plumber and made the right recommendation. I had no choice and had to replace it that day. The cost was $13k. Needed to put down a 50% deposit As a point of info last year GG installed a new $14k heat pump. I asked if the balance could be paid in 30 days. Mgt told my sales person NO. Balance due now. Not everybody in these times has $13 k available on a minutes notice. Bottom line a rating of 5 for sales and installation. A rating of zero for the greedy owner with no compassion for a repeat customer
AC was out in our office for a few days these guys were able to get it up and running within a few hours. Tech was very nice and professional explained the issue well and got it fixed fast fast.
Professional courteous knowledgeable… thought it would take months to have my HVAC unit they completed within a couple of weeks. Mike Baldwin in sales & the installation team (wish I got their names) were awesome support services excellent they are my go to now I am a newly loyal customer I give them a 10!
