Just completed AC tune up with Nick R. Courteous and knowledgeable service. Thorough and friendly. Arrived on time and explained his intent. Highly recommend!
Richard F. was the first Gem employee I met. My original appointment was to have the air conditioner yearly service (central air). After opening the side panel Richard showed me the black mold and rust inside the unit. NO ONE had ever opened the side panel during a yearly service appointment. There were years of built up black mold. I will NEVER use the companies I have used in the past. Richard presented 2 options. He was not pushy. He simply presented the information to me and answered all of my questions. Richard is respectful both professionally and personally. We scheduled the appointment for the following day (removal of the old unit and condenser and installation of the new.

The following day Richie and John arrived at 7:45AM. Leo then arrived. They worked from the time they arrived (7:45AM-5:00PM) until they completed the job. They are respectful both professionally and personally. They thoroughly explained all the work they did and gave me information that I did not know previously. Again, we get the a/c serviced yearly and no one had ever explained anything. They cleaned up after completing the work. I mean immaculately.

FAQ

Do you offer 24/7 emergency AC repair?

Yes. GEM provides emergency air conditioning repair in Brockton around the clock. No matter when your system fails, our technicians are ready to respond and restore your comfort.

Why does my AC smell musty or strange?

Musty odors often indicate mold or mildew growth in your system or ductwork, while burning smells may signal electrical problems. Our air conditioning repair technicians in Brockton will identify the source and eliminate it to protect your indoor air quality.

When should I replace my AC instead of repairing it?

Consider replacement if your system is over 15 years old, requires frequent repairs, uses outdated R-22 refrigerant, or no longer cools efficiently. GEM’s air conditioning repair specialists in Brockton will assess your equipment honestly and recommend the most cost-effective option.

Why does my AC run all the time without cycling off?

Constant running typically means your system can’t reach the thermostat’s set temperature. Causes include low refrigerant, dirty coils, an undersized unit, or extreme heat. Our Brockton technicians will diagnose the issue and restore proper operation.

How often should my air conditioner be serviced?

Annual maintenance is recommended to keep your AC running efficiently and catch problems early. For older homes like the three-deckers near downtown Brockton or the mid-century ranches throughout Campello, regular tune-ups are especially valuable for keeping aging equipment reliable.
