Christopher, was great he came to do what he had to do. He got a job done. And I'm very pleased with her, thank you, Chris.
Solved issue with Furnace. Friendly and respectful.
Brandon’s work was on time and professional as always!!
Steven and Diego arrived to check out our system and were able to get everything up and running. They were professionally, efficient and friendly. GEM Plumbing employees are always top notch!
Two technicians came to assess my minisplit which has been leaking. They spent a lot of time working hard to find an answer which unfortunately ended in needing a follow up appointment with a handyman through GEM, to resolve an issue with my unit. But while the techs were here they really tried very hard to resolve the issue. I give them an A for effort.
New resident needing plumber to improve drainage of bathroom sinks and stop leaky faucets. As first plumber I called did not call me back, I called Gem for help. William and Mark were sent to provide service within 2 hours. Problems corrected after thorough discussion of options and pricing for each. Selected the replacement option for leaking faucets, which resulted in spending more money than anticipated, but they selected good looking faucets from supplier and returned to install them. I elected to enter into a one year contract to secure HVAC service for the year, eliminating the dispatch fee. I am pleased with the new well functioning faucets. Good communication with technicians and office representative, Melissa.
They were both great. They explained everything very well.
The best. Great communication, clear pricing, does the whole job and doesn't leave until everything is handled. I have referred them to several people because trustworthy people are hard to find
Very professional and knowledgeable on what needs to be done
Did a great job
The crew.
Was very respectful of my property and worked very efficiently. The clean up after the work was accomplished was impeccable. I highly recommend them without reservation.
Very responsive to my off-hours request for heating repair on a holiday weekend; technician resolved problem. Communication was very good (updates about arrival time, etc.).
John P replaced a capacitor on my AC unit and got it working again. He had to get onto the roof to reach it which is not easy. I asked John a lot of questions about AC and heating units and he is very knowledgeable and helpful
If I could give Douglas 6 stars, I would. He is knowledgeable, and really cares. Did a great job and made recommendations. Not his first time here and always detail oriented.
Anthony Pena was great, he did great work, very fast on fixing our 1 year old water heater union valve and was very nice
Highly recommended 5 stars all day

Great service. On time and reasonably priced. Came out to double check on an issue that was still unresolved at no charge.
I got Steve and his colleague from GEM Plumbing to work on my heat pump. I would highly suggest them. They were very patient with all of the explanations of what was wrong and made sure I understood everything. They also gave me a rundown on changing air filters and educated me on all of the necessary information. Overall, I had a pleasant experience. The entire process, including diagnostics and problem resolution, took less than two hours.
James called explaining he was at our cottage for AC maintenance and checking on our new system.
Quick, easy, efficient and clean and Courteous.
Brody and his assistant did an amazing job fixing out central air. Both were friendly and super knowledgeable. GEM got us a small day appointment. If your looking for a company that has your back, look no further.

Warning Signs It’s Time for AC Replacement in Eastham

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 Eastham.

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 Eastham cuts energy consumption dramatically while providing superior cooling performance and long-term reliability.

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 Cape Cod home. Air conditioning installation in Eastham ends this expensive cycle and delivers dependable performance you can count on throughout summer.

Most air conditioners deliver reliable performance for 12 to 18 years before natural efficiency decline begins. Systems exceeding this age develop problems more frequently and cost more to operate. When your equipment passes 15 years, replacement typically makes better financial sense. Contemporary systems deliver enhanced cooling with reduced energy use, improving comfort while lowering monthly expenses for Eastham homes.

Grinding, squealing, or banging noises reveal serious mechanical deterioration happening inside your system. These sounds indicate components breaking down or mounting stress that escalates with continued use. What starts as occasional noise typically progresses to complete failure. Replacement eliminates these problems while providing quiet, dependable cooling backed by modern technology and warranty protection.
