Here’s How to Tell if You Need a New Generator

If your system is showing signs of wear or inconsistent performance, it may be time to consider a replacement.

If your generator needs regular repairs or service calls, it may be reaching the end of its lifespan. Ongoing issues can quickly add up, making replacement the more reliable and cost-effective option.

A standby generator should turn on automatically when the power goes out. If it hesitates, struggles, or fails to start at all, your home could be left unprotected during an outage.

If lights flicker, appliances struggle, or your system can’t power essential equipment, your generator may be undersized or losing capacity. A replacement ensures your home gets the dependable coverage it needs.

Outdoor generators are exposed to the elements year-round. Significant rust, corrosion, or physical damage can impact performance and signal it’s time for an upgrade.

Nice people, quick to respond and knowledgeable. Highly recommend them for emergencies. William T. was great, thank so much
First maintenance on our Generac. All went very smoothly!! Arrived within timeframe provided and even informed on actual arrival that day!
Very polite gentleman who went right to work, provided an update once maintenance was completed and explained basic process performed.
David S, our GEM technician was on time, respectful of our home and provided us with a thorough explanation of our GEM service contract and the scope of work completed and recommended. I would highly recommend him again!
Alec and Scott made quick work of what turned out to be a simple solution. Very efficient, pleasant and explained the issue and recommendation clearly.
Both service calls to my house were with Nick, and I can't say enough good things about him. He's professional, courteous, communicative, and thorough. My only hiccup with Gem has been conflicting information from the office, but even with hiccups the staff have been professional and friendly. Thank you, Gem! You're the best, Nick!
great guy! vaery talented and professional
Joseph (Junior) from GEM Plumbing & Heating came out to do a check on our HVAC system for this season. He was very thorough, knowledgeable, and honest. Our system is in great shape after 16 years. Thank you Joe!!! We were on a contract plan, which was very reasonable, so we paid nothing at the time of service.
Our tech was Joseph (junior), Incredible experience came out the same day.Billed me for the service. Exceptional diagnostics, developed a number of options to fix the problem. We called four other places.First three never showed one showed and walked away, without figuring anything out. Our A/C has been out for 6 wks waiting for people to not show up. YOU ABSOLUTELY MUST CALL GEM FIRST
GEM responded very quickly. I was out of state when my tenant called stating the A/c system wasn't working. I called GEM to see if they would be willing to help me. I didn't have an account with them but they were more than willing to assist me with my broken A/C system.
Nick the technician was very knowledgeable and worked with me while I was out of state and with my tenants. He articulated very well, explaining all the issues, what the repair process would involve and the cost. There were no surprises. My tenants informed me that Nick was terrific !
Nick got the system up and running. Overall, it was a very positive experience and I would highly recommend GEM to anyone.
Great service. Timely response and got the job done. It’s on the pricey side but that’s expected given their quick response time. Joe was particularly good and have had him out twice on our property. Thanks!
From beginning to end the experience was amazing. It started with my man Walter who calmly with humor explained the process and my guys Ben and his partner who took cared of me and my family. They were professional and very knowledgeable about the process. Their patience when not finding my well was welcome. Awesome job
Thank you
The people are nice, punctual, pleasant.
And best of all great prices. I'm very happy with the service.
I was very impressed with Dory . He was extremely knowledgeable and very helpful.
Awesome service and friendly guys.
My name is Fred Brundage West Dennis MA
I had one of Gem Heating and Plumbing plumbers Christopher Rogan repair two broken gas line on an emergency basis. Chris was very professional, courteous and willing to make sure that the inspector was available once the job was completed. I was on a tight schedule to open the house. Gem Heating and Plumbing is a company that can be relied on.
Joan was very helpful – but his arrival was very delayed and communication was not great
They came over right away, diagnosed the problem and fixed it. Fast courteous service.
Chris from GEM arrived as scheduled and resolved a no hot water issue. I even got a GPS map for his truck to our location, and notified when he would arrive. No other company after several calls ( including one we have used for over 7 years would be able to help us for 10 days. With three women in the house that would not work.
Chris diagnosed and fixed our furnace which controls the hot water.
I will be using GEM in future for sure!
Excellent response, installation and knowledgeable services. Technicians were polite, prompt, professional, and kept us informed throughout the job. Would gladly use them for all future HVAC work and service.
Excellent knowledge followed by superior customer service
Jim was great! Pleasant, knowledgeable and helpful. He took the time to give me a few options and explained pros and cons. I am very thankful for his input and careful work! He replaced and upgraded faucets outside and new hoses to my washing machine!

Nick was great! He was presented with an unfixable AC problem. I was so impressed that he found this little piece of broken plastic tha caused such a water leak. He was very helpful in explaining options and estimate cost. He also climbed high up on a ladder inside and out to clean my filters. I’m so thankful.
!!
Employee was great. He explained what needed to be done and costs. Unfortunately, I had a leak in the AC line where it connected to a head unit on a system that I had installed by another company 4 years ago. All the refrigerant leaked out over that 4 year period. I feel this should have never happened and been found during their pressure test.
Anyhow, $3100 later, repaired. Just wished it hadn’t cost so much but not GEM’s fault. As far as the pricing, I have no idea.
Eric and the young lady were wonderful. They worked continuously and neatly all day
Michael M. from GEM was professional, knowledgeable, and courteous. He diagnosed the blockage problem and rectified it promptly. Five stars for his expertise!
David was a terrific through out the entire process. Great water filtration system installation and also great walking me through the process. Highly recommended.

Different generators come with different capacities and features, and choosing the right one can feel overwhelming.
