Here’s Why You Should Replace Your Water Heater

Water heaters don’t improve with age. Here’s what a new one actually delivers.

Older units work harder to produce less. New water heaters are engineered for efficiency—same hot water, smaller energy bill.

No more rationing showers or timing laundry around recovery periods. A new system keeps up with your household’s actual demand.

Aging equipment breaks down more often. Replacing now ends the cycle of service calls and parts replacements that add up over time.

Mechanical systems matter to buyers. A new water heater signals that the home has been maintained, and that affects resale value.

Very fast install of 7-zone mini split system and required panel upgrade. From first call to work completion was less than a week. No quality issues of install and the workers were great. Overall GEM is very expensive, but quality and speed are fantastic.
Just completed AC tune up with Nick R. Courteous and knowledgeable service. Thorough and friendly. Arrived on time and explained his intent. Highly recommend!
Richard F. was the first Gem employee I met. My original appointment was to have the air conditioner yearly service (central air). After opening the side panel Richard showed me the black mold and rust inside the unit. NO ONE had ever opened the side panel during a yearly service appointment. There were years of built up black mold. I will NEVER use the companies I have used in the past. Richard presented 2 options. He was not pushy. He simply presented the information to me and answered all of my questions. Richard is respectful both professionally and personally. We scheduled the appointment for the following day (removal of the old unit and condenser and installation of the new.

The following day Richie and John arrived at 7:45AM. Leo then arrived. They worked from the time they arrived (7:45AM-5:00PM) until they completed the job. They are respectful both professionally and personally. They thoroughly explained all the work they did and gave me information that I did not know previously. Again, we get the a/c serviced yearly and no one had ever explained anything. They cleaned up after completing the work. I mean immaculately.
He came over on Easter Sunday and helped us with a big problem that could not wait. He explained everything in detail. He stayed until the problem was resolved. Really nice guy.
Tech was efficient, skilled, client focused and really nice
Very professional and nice. Answer our questions, highly recommended

Water Heater Replacement FAQs

Should I choose a tank or tankless water heater for my New Bedford home?

Depends on your usage and space. Tank units cost less upfront and work fine for most households. Tankless units cost more but deliver unlimited hot water and last longer. Our plumbers can walk you through the tradeoffs for your specific situation.

What rebates are available for New Bedford homeowners?

Mass Save offers rebates on qualifying high-efficiency models, including heat pump water heaters. GEM helps you identify eligible equipment and submit the rebate application.

How long does water heater replacement take?

Two to four hours for most installations. Tankless conversions or situations requiring electrical or venting work take longer. We give you a time estimate before we start.

Does GEM remove my old water heater?

Yes. Removal and disposal are included. You don’t need to arrange anything separately.
