The service was good.Aiden was very good. It’s just they said they were on there way 2hrs and30 min they finally arrived. Waited all afternoon
The 2 service men were on time, assessed the problem, diagnosed the issue, came up with a plan and offered several solutions for fixing our mini split. They took pictures, tried clearing out mice debris , attempted to get the outside machine to work ( apex 2 hours) Alas a no go, so we decided to scrap it and go with baseboard heater for the room over the garage. Up front information and pricing , no nonsense. Affable techs and so far great service.

I was thoroughly impressed with the superb HVAC maintenance service I received from David Santiago and trainee, Kevin today! Before David and Kevin arrived I was very disappointed with having had my original service date rescheduled to what I thought were spurious reasons? In fact David and Kevin arrived after the designated rescheduled date and time today. GEM's communication was excellent throughout and their people seemed genuine and concerned. When David and Kevin arrived it turned the whole situation around. They could not have been more professional and knowledgable! I am now firmly committed to GEM and their Home Comfort maintenance program.

We just had our heating system replaced. We went from forced hot water system to a central heating and air conditioning system done by GEM plumbing and heating company We had Omar and Michael work in our home for 5 days they installed all the ductwork, the furnace and the condenser. These guys were very professional, kind, clean and informative throughout the whole install every day they explaind what they did and what is the expectation for the next day. Today was the last day they walked me through the whole system, how to change the filter how to operate the new thermostat and what to look for when things are not working properly. I say thank you to the whole team from planing to done, all went great to expectations

FAQ

Do you provide emergency AC service throughout Quincy?

Yes. GEM offers 24/7 emergency air conditioning repair across all Quincy neighborhoods, from Marina Bay to Houghs Neck, Wollaston to West Quincy. Our large fleet ensures rapid response wherever you are in the city.

Can you service ductless mini-splits in Quincy?

Absolutely. Many Quincy buildings use ductless systems rather than central air. Our technicians service all major brands and can repair or recommend replacement for any system type.

What energy rebates are available to Quincy residents?

As a Mass Save® partner, GEM helps Quincy homeowners and condo owners access rebates for energy-efficient equipment upgrades. We’ll guide you through available programs and help you maximize savings.

Why does my Quincy waterfront condo stay humid despite AC?

Coastal humidity near the bay is higher than inland areas. If your condo feels clammy despite running AC, you may have an undersized system, low refrigerant, or drainage issues. Our technicians diagnose the specific cause and restore proper dehumidification.

How often should Quincy residents schedule AC maintenance?

Annual maintenance is recommended for all Quincy properties. Waterfront and near-water locations that face salt air exposure benefit especially from regular tune-ups that catch corrosion early and maintain system efficiency.
