Here’s Why You Should Replace Your Water Heater

No water heater lasts forever. Replacing before total failure gives you control over the timing and the outcome.

Newer water heaters are built to use less energy while delivering the same hot water. That efficiency shows up on your utility bills month after month.

A new system means consistent hot water without the temperature fluctuations or capacity problems you’ve been experiencing. It just works.

Quality installation by experienced plumbers extends equipment life and prevents the problems that come from rushed or sloppy work. You’re investing in reliability.

Buyers notice mechanical systems. A new, efficient water heater signals a well-maintained home and can positively affect resale value.

Don’t Trust Your Home & Family to Just Anyone.

Eric Governor from GEM came to my house today. I was very overwhelmed with the electrical issues I was having and he took his time explaining everything to me and what my options were. He didn’t leave until I understood what was needed. They were very nice and made me feel comfortable.

Was able to receive last minute, same day service from Abe and Logan. They were prompt, courteous and saved us a boat load of money. They found our tub leak easily and took care of it immediately allowing us to choose the repair option that was in our budget. Thanks very much!
Nancy Hoffler
Every person I dealt with at GEM was very professional and very pleasant. No long wait for the house call or the installation.They installed my three mini-splits and condenser in under 7 hours and cleaned up after themselves. The entire team of four men knew exactly what they needed to do. I would highly recommend them.
Mike
Excellent Service
James Sidman
I had my A/C go down on a 90° Friday. GEM sent David Salvatore to my house same day, and he was back first thing Monday morning with the parts to repair. He was an honest gentleman and a clean worker. He even found me a first time customer coupon to save me a few dollars. Are they priced a bit higher than some other companies? Yes, they are. But my existing company, Mutual Engineering, wasn’t even going to come for a diagnosis for a week! This is a perfect example of you get what you pay for. In addition to this condenser repair, David showed me maintenance that I should have been doing on a separate mini-split system installed by my now previous company. Mutual Engineering never informed me of this requirement. Bottom line is when it’s extreme heat or cold and your HVAC goes down, you want service quickly. I got that, and it was worth every penny.

We discovered a leak under our kitchen sink and as luck would have it, we had company coming to our house the following day. A neighbor gave me the name and phone number to GEM Plumbing. They came to our rescue and their guys were here the following morning, right at the promised time. We were very happy with their two guys and all was fixed within a few hours. Thank you so much!!!!!!

Katia T
Steven was great to work with and explained the issue we were having very well.
Erin Corshia
Edward was great. My mother was having a drainage issue. Other companies have come in and charged her money and not fixed the problem. Edward got down to the root of the problem and fixed it for us. Response time is quick. I booked the appt on Tuesday evening they were there Wednesday morning. In the past my husband and I have used GEM for an emergency where we called at 7am and they were there by 9 same day. Obviously those things cost money, but it is very reasonable for what you are getting. I would absolutely recommend GEM to family and friends.
Nicole Laliberte

Rishabh jain
I had a water leak in the AC unit and while they were here also found out that the capacitor was old and needed to be changed to get to right cooling temperature.
A little pricy , l paid $750 for a new capacitor and removal of some debris in the water collector in Ac unit.

But it still great , since they showed up as same day appointment and fixed everything.
Nicholas was very professional and did the job quickly.
Jeny M

Annual maintenance extends your water heater’s life and keeps it running efficiently.

Sediment builds up, anode rods corrode, and connections loosen over time. Catching these early prevents bigger problems later. GEM offers maintenance services that protect your investment and keep efficiency high. Call GEM today to learn more.

Water Heater Replacement FAQs

How do I choose between tank and tankless for my Lexington home?

It comes down to usage, space, and budget. Tank units cost less upfront and handle moderate demand well. Tankless costs more initially but delivers unlimited hot water and typically lasts longer. Our plumbers can evaluate your situation and recommend what makes sense.

What’s the most energy-efficient water heater option?

Heat pump water heaters are among the most efficient, using electricity to move heat rather than generate it. High-efficiency tankless models also perform well. Mass Save offers rebates on qualifying equipment, and GEM can help you identify eligible models.

Does GEM offer same-day water heater replacement in Lexington?

Yes. We understand hot water failures are urgent. Our team size and stocked trucks allow same-day service across Lexington when you need it. Call early in the day for the best availability.

How does local water quality affect water heater lifespan?

Hard water causes faster sediment buildup, reducing efficiency and shortening equipment life. Regular maintenance, including annual flushing, mitigates this. GEM’s technicians can advise on maintenance schedules appropriate for Lexington’s water conditions.
