Very professional and thorough. Serviced not only my mini-split but my air conditioner and checked my furnace and changed it's filter. Very happy.
The folks at Carmine's/GEM always do a great job👍 Anthony Pena did a great job checking the gas dryer connection and valve. Made sure everything was working properly and that there were no leaks.
Joan Martinez came to my house on an emergency call when my furnace/boiler broke down at 1 am. He diagnosed the issues and unfortunately I needed a new system. GEM installed the new system over the next two days. Everyone on the crew was excellent. I signed up for GEM’s maintenance program because if I had previously it would have prolonged the life of my furnace/boiler. Today Joan Martinez returned to do routine maintenance on my mini splits. He was very thorough and made sure the units are ready for the summer season. I highly recommend and trust Joan Martinez for any 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.
