Here’s Why You Should Replace Your Water Heater

A water heater replacement done properly pays off for years. Here’s what you get when professionals handle the work.

Water heaters built today meet stricter efficiency standards than units from just a few years back. Installation by experienced plumbers ensures those efficiency gains actually show up as lower bills over the system’s lifetime.

A new system put in correctly delivers consistent hot water when you need it. Work done right means no callbacks, no drips, no issues appearing later.

When professionals with real experience install your water heater, it runs better and lasts longer. You’re paying for craftsmanship, not just hardware.

A modern, efficient water heater adds comfort and savings while increasing what your home is worth. Buyers can tell the difference between professional work and shortcuts.

Super fast response time (called at 4:00 on Monday and Mike & Chris were at the house at 11:15 on Tuesday). Mike and Chris were excellent, diagnosed the source of the odor (bad wax ring) and completed the job by 12:15.
Everything from the initial phone call to the quick response from our techs and the repair of our system was an A+! Would recommend to everyone.
GEM was one of only services that got back to me and scheduled me on the same day! Colin was quick, professional, and someone I felt safe having in my home. You get what you pay for!

Khorey J. and his colleague did an excellent job inspecting our heating and cooling mini-split system. They took the time to explain the issues in detail and gave us peace of mind and at ease by ensuring that everything was working properly. They also explained and demonstrated when the condenser fan should turn on at various temperatures and settings. Both men were knowledgeable, professional, polite, and respectful. We have been customers of Gem Heating and Plumbing for many years, and, as always, they were there when we needed their services. Thank you, Gem Plumbing!

Have used GEM several times. After some rough experiences with some other HVAC companies, I can say GEM has been consistently outstanding. Highly recommended.
We had an emergency service performed on Saturday, the technician Chris was professional and talked me through everything he was doing. I’d rate his overall work on a scale of 1-10 as over 10 because he was that awesome. What gets me is the pricing of the service. As I mentioned it was an emergency, and as the customer I want an itemized breakdown of parts and labor. I just called GEM and they mentioned they do not provide that. I will continue to call until I get the satisfaction I want on full disclosure of MY billing statement the was paid for in FULL by MYSELF. I know GEM reads these reviews and I want my fully itemized bill for services rendered.
Very satisfied with the service
