Two Gem workers showed up to do annual service on time. Dave and his coworker were friendly, professional and excellent communicators.
The professionals from Gem came to our house to fix a leaky well pump. Fortunately, they diagnosed the problems, and were able to replace our well and tank all in one day. They showed me how bad the pump and tank were, gave us options, gave us estimate. After everything was installed they tested everything to make sure it was in working order. I had a great experience, and I would highly recommend using them. I cannot thank them enough.
Chris and Nem cleaned & checked the parts of my A/C system making sure all was functioning properly. Both helped me have a better understanding of how the unit works & things to consider as upgrades to the HVAC system. Based on their visit I plan to renew my annual maintenance plan.

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Consider replacement if your system is over 15 years old, requires frequent repairs, uses outdated R-22 refrigerant, or no longer cools efficiently.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.
