Here’s Why You Should Replace Your Water Heater

Your water heater already failed. Here’s what a new one delivers.

The most immediate benefit: hot water again. Showers, dishes, and laundry can happen normally starting today.

Your old system failed you. A new water heater provides steady, dependable hot water without the worry of another breakdown.

That old water heater was probably wasting energy before it died. Your new system will use less energy for the same hot water output, reducing utility costs going forward.

Replacing now means you won’t face this emergency again anytime soon. A new unit performs reliably for 10 to 15 years with proper maintenance.

Joe did a wonderful job of coming to check my HVAC system prior to this coming summer. I was extremely pleased with his efficiency and the timely manner in which it was accomplished. Thank you Joe!
Always reliable and courteous service! We have relied on GEM for regular maintenance, repair services, plumbing, new HVAC installation, and even shower installation. We feel we can cou t on GEM to be there when we need them and always perform great work.
Excellent service, highly recommend
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.
While the repair was simple, Stephen and Eric were very professional and courteous.
We were very pleased with Gem’s air conditioner maintenance service. Dory and his team did an exceptional job. They explained what they were doing and shared helpful information about maintaining our HVAC system.
Joe, the service person who came to fix our water heater, was amazing. Calm, expert, efficient and best of all very interested in showing me (and teaching me about) what was going on. It's really important to be knowledgeable about your own home. The problem has been fixed and I also know what to look out for in the upcoming months and years. The service (and parts) weren't cheap. Phew. But I have a good sense that the good service that Joe provided will ultimately save us money in the long run as we care for our system.
great service again
Jared was great, super knowledgeable super personable, easy to work with.
Joe Kiff from GEM Plumbing & Heating came out for our annual central air system checkup. He arrived on time, clearly explained what he planned to do, walked me through everything afterward, and offered helpful suggestions for a few improvements. Overall, excellent service!
Outstanding job from response within 24 hours, to assessment within 48 hours and full job complete within 72 hours, all within a reasonable budget. Great team of Chris, Baxter and Joe. Couldn’t be more pleased with their work or them as friendly professionals.
I called upon Gem Plumbing for a washer / dryer install, in my condo. I needed water pipes moved and shut off valves installed – the whole nine yards. Gem sent Walter P to give an estimate and to do the job.
Walter in a fine young gentleman, very kind and courteous. He explained the work that needed to be done. He came in and did the job. Now I have a full laundry set up in my condo. Thank you Walter so for a Job Well Done. I will highly recommend Gem Plumbing to anyone who needs expert service. And I will certainly call upon them for any services I need in the future. Thank you.
Great work by all of the GEM workers at our house! Had a somewhat difficult situation to resolve and they got it done!
Timothy was great. Friendly, knowledgeable and professional
Bob was a very nice man. Fixed our ac and did the yearly maintenance. It was a pleasure meeting him.
Mason did an excellent job replacing my hot water heater. He was knowledgeable, professional, and personable. I was extremely happy with his service.
Very happy with the technician that came to our house- very thorough and informative.
Friendly, courteous and professional service. Happy to have them as my service provider.
Work was completed professionally and completely. Nick offered ideas and alternative approaches and recommendations. They responded quickly.
Mr. Liu and his GEM in training arrived on time and with phone calls that let us know their efforts were booked after our appointment. But…they took all the time they needed to assess what could have been a messy reinstall of a bath light/exhaust fan in a 1955 house. Although adequately warned that something other than pretty could happen, they made surgical cuts to enlarge the ceiling hole with minimal degradation of the ceiling. Despite the number of sawzall blades they’d used, we
were all smiling when we turned the fan on for the first time. Another successful visit by the GEMs.
(As always, my only hesitation in using GEM for future projects is the pricing process.)
The guys were professional and provided education on what was needed to fix our issue. Thanks to both of them!
This is third time we've used this service and they responded to an emergency a little outside their expertise when no one else would. They are quick, professional and knowledgable. Very responsive and worth the money!
Great communication and prompt service. Tyler was polite, knowledgeable and professional.
Efficient, friendly guys replaced my whole HVAC system in less than a day.
From the very beginning everyone we dealt with at GEM were professional, knowledgeable and helpful. The installation process was as promised and was efficiently completed. An outstanding job by all. Thank you.
