Super fast response time (called at 4:00 on Monday and Mike & Chris were at the house at 11:15 on Tuesday). Mike and Chris were excellent, diagnosed the source of the odor (bad wax ring) and completed the job by 12:15.
Everything from the initial phone call to the quick response from our techs and the repair of our system was an A+! Would recommend to everyone.
GEM was one of only services that got back to me and scheduled me on the same day! Colin was quick, professional, and someone I felt safe having in my home. You get what you pay for!

Khorey J. and his colleague did an excellent job inspecting our heating and cooling mini-split system. They took the time to explain the issues in detail and gave us peace of mind and at ease by ensuring that everything was working properly. They also explained and demonstrated when the condenser fan should turn on at various temperatures and settings. Both men were knowledgeable, professional, polite, and respectful. We have been customers of Gem Heating and Plumbing for many years, and, as always, they were there when we needed their services. Thank you, Gem Plumbing!

Have used GEM several times. After some rough experiences with some other HVAC companies, I can say GEM has been consistently outstanding. Highly recommended.
We had an emergency service performed on Saturday, the technician Chris was professional and talked me through everything he was doing. I’d rate his overall work on a scale of 1-10 as over 10 because he was that awesome. What gets me is the pricing of the service. As I mentioned it was an emergency, and as the customer I want an itemized breakdown of parts and labor. I just called GEM and they mentioned they do not provide that. I will continue to call until I get the satisfaction I want on full disclosure of MY billing statement the was paid for in FULL by MYSELF. I know GEM reads these reviews and I want my fully itemized bill for services rendered.
Very satisfied with the service

Warning Signs It’s Time for AC Replacement in Cambridge

Your air conditioner sends clear signals when replacement makes more sense than another repair.

These warning signs tell you it’s time to consider new air conditioning installation in Cambridge.

Repeated service calls drain your budget while providing no long-term solution. Aging systems develop cascading problems where fixing one issue reveals another. You’re maintaining failing equipment instead of investing in reliable cooling for your Metro Boston home. Air conditioning installation in Cambridge ends this expensive cycle and delivers dependable performance you can count on throughout summer.

When cooling costs climb month after month despite stable usage, your system is losing efficiency. Age and component wear produce this gradual decline. What once cooled your home efficiently now struggles, consuming excessive electricity while delivering diminishing results. Modern air conditioning installation in Cambridge cuts energy consumption dramatically while providing superior cooling performance and long-term reliability.

Air conditioners generally perform well for 12 to 18 years before efficiency naturally drops and problems multiply. Equipment beyond this age costs more to operate and repair than modern replacements justify. When your system reaches 15 years, replacement typically delivers better long-term value. Contemporary systems incorporate technology that achieves superior cooling with minimal energy consumption, reducing both monthly costs and breakdown frequency for Cambridge homes.

Your air conditioner shouldn’t operate continuously just to maintain barely adequate temperatures. When your system runs all day but rooms stay warm, it’s revealing it can no longer meet your cooling demands. This constant operation wastes energy while failing to deliver proper comfort. Professional air conditioning installation in Cambridge provides properly sized equipment that maintains consistent temperatures throughout your home without excessive runtime.

Every Cambridge home has unique cooling requirements, and GEM offers energy-efficient systems to match your needs.
