Excellent service in every respect: starting with the salesperson, Peter Dallas; Sean, the installation coordinator; and, of course, the installers Joe & Cristar!!
Pete was extremely professional, friendly, understanding and very flexible when negotiating the final price.
After 28 years of using a Lennox central heating and air conditioning system, we decided was time to get new systems and we went with Carrier this time, a highly respected brand too backed by GEM Plumbing as a certified provider. Both the sales process and the speed of the installation were incredibly efficient. We spoke with Peter on a Tuesday morning , and by 3:00 p.m. on Friday of same week the installation was complete. We were lucky enough to have Joe Medeiros and Cristar Fig from GEM as our technicians!
Let me tell you, this duo is exceptional! They are very young but possess extensive knowledge and a fantastic attitude. I was truly impressed by their technical work and their courtesy. These two technicians are a great asset to GEM and WE would love them to be recognized! We are very happy at home; the air conditioning system works wonderfully! And We can’t wait to use this coming winter our new furnace too!
Thanks to Peter, Sean, Joe, and Cristar for their amazing job!!

FAQ

Do you provide same-day AC repair throughout Somerville?

Yes. GEM offers same-day air conditioning repair across all Somerville neighborhoods, from Davis Square to Assembly Row to Winter Hill. Call before noon and we can usually get there the same day.

Can you service ductless mini-splits in Somerville?

Absolutely. Mini-splits are common in Somerville’s condos and multi-family buildings. Our technicians service all major brands and can repair or advise on replacement when needed.

What energy rebates are available to Somerville residents?

As a Mass Save® partner, GEM helps Somerville residents access rebates on qualifying high-efficiency equipment. Rebates change seasonally, so we check current offers and handle the paperwork for you.

Why does my Somerville home stay humid even with AC running?

Somerville’s dense housing and older construction often mean undersized equipment or systems that can’t keep up with humidity. You may need a capacity assessment, condensate drain cleaning, or whole-home dehumidification. Our technicians diagnose the actual cause.

How often should Somerville residents schedule AC maintenance?

Annual maintenance is recommended, ideally in spring before you need cooling. Older systems and units in triple-deckers that run hard all summer benefit especially from yearly tune-ups that catch refrigerant leaks, electrical wear, and airflow problems early.
