I’m very pleased with the work done by Cristian & his helper. Communication was very much appreciated – every question was answered and explained throughout the entire project. It’s rare to find someone who takes pride in their work these days. I would highly recommend GEM to anyone looking for a skilled contractor.
Had a leaking T&P relief valve on my water heater. Called GEM, they came out just a few hours later, replaced the valve with a new one, and they could not have been nicer or more professional. Very satisfied and grateful for their speed and knowledge. Would absolutely call on them again. I did not pay anything because I am under warranty.

We needed a new furnace. They sent someone out the next day to provide an Estimate. The price seemed reasonable and the discounts made it even better so I booked them to complete the job. I received a call later the same day and had the furnace installed the following day by Ethan and Kevin. The following Monday, my furnace would not fire. After evaluating the situation it was found that we needed to relocate our exhaust pipe. Ethan and Kevin were sent to do the job. The original installation was done in less than a day and assessing and relocating the exhaust pipe was done in a few hours. I am happy with the service.

Both David C was excellent! Hecame on time, walked me through what needed to be done, and when completed showed me the final product. He was very professional, pleasant and respectful of our home. I strongly recommend him for any repairs needed.
Their $99 promotion — main drain cleaning + camera inspection — is a great deal. The guys who did the work were very systematic, surveying the drain pipe both before and after cleaning it out, and explaining what they found very clearly. They followed up with a proposal for fixing the pipe. I will of course bid out the repair, and I have no information about how efficient and economical they are for doing this work.

Living on the Cape finding a reliable service company can be difficult. GEM is now my go to for HVAC and plumbing service.
> Five stars for Davontay V. He came out to our Foxborough building for a no-heat call, found a loose heat-call wire in minutes that the previous tech had walked right past, reconnected it, and there was no charge for the visit. Professional, fast, and honest. He's our requested tech from now on. Additionally, Davontay also put the lock cover back on, locked up every door, shut off the lights, and took care of a few small cleanup items that weren't part of his job — all without being asked. Great job!

How to Know When You Need a New Water Heater Installed

A failing water heater shows clear warning signs.

Our experience serving Exeter has taught us what these symptoms mean. Let us help you evaluate your water heater’s condition.

Most water heaters last 8 to 12 years. If yours is in that range or older, efficiency has likely declined and a breakdown could happen any day. Replacing proactively means you choose when it happens, not your water heater.

Rusty or discolored hot water often means corrosion inside the tank. While a failing anode rod can sometimes be replaced, rust in an older system usually signals the tank itself is deteriorating. New water heater installation in Exeter restores clean, clear hot water.

If your water heater used to bounce back quickly but now takes hours to reheat, sediment buildup or failing components are reducing capacity. When flushing no longer helps, water heater replacement in Exeter is the fix.

Strange sounds during heating cycles usually indicate sediment has hardened at the bottom of the tank. This forces the system to work harder and can eventually cause cracks. When flushing doesn’t quiet the noise, replacement makes more sense than waiting for failure.

We Install All Types of Water Heaters in Exeter

Today’s water heaters offer several technologies, each suited to different situations.

GEM helps Exeter homeowners choose and install the right system. Here’s what’s available:

Tankless systems heat water on demand rather than storing it. Cold water flows through and emerges hot when you turn on a faucet. This provides unlimited supply without standby energy waste. GEM installs tankless water heaters in Exeter for homeowners wanting efficiency and endless hot water.

Conventional tanks maintain heated water ready whenever you need it. These reliable systems offer proven performance and reasonable costs. Most Exeter families find tank heaters deliver dependable daily performance.

Hybrid technology extracts warmth from surrounding air to heat water, achieving efficiency far beyond conventional heaters. They keep a tank of hot water available while reducing energy use dramatically. Exeter homeowners focused on long-term savings often choose hybrid models.

Water Heater Installation FAQs

What are the pros and cons of tankless water heaters?

Tankless units provide unlimited hot water on demand and typically last longer than tank heaters, often 20 years with proper maintenance. They’re compact and efficient. The downsides: higher upfront cost, potentially expensive installation if your home needs electrical upgrades or gas line modifications, and flow rate limitations that may not suit large households using multiple fixtures simultaneously. GEM can help Exeter homeowners decide if tankless is the right fit.

Can GEM handle water heater emergencies in Exeter?

Yes. We provide 24/7 emergency service throughout Exeter and the Washington County area. If your water heater fails unexpectedly, leaks, or poses a safety concern, call us immediately. Our technicians can respond quickly to assess the situation and get your hot water restored as soon as possible.

Can I install a water heater myself?

We don’t recommend it. Water heater installation involves gas connections, electrical work, plumbing, and venting that require proper training to do safely. Mistakes can create fire hazards, carbon monoxide risks, or water damage. DIY installation also typically voids manufacturer warranties and may not meet Exeter building codes. Professional installation ensures safety and code compliance.

What size water heater do I need for my Exeter home?

The right size depends on your household’s actual hot water usage, not just your home’s square footage. A family of four in Exeter typically needs a 40 to 50 gallon tank, while a couple might be fine with 30 gallons. GEM’s technicians consider peak usage times, like when everyone’s getting ready in the morning, and recommend a size that meets your demand without wasting energy heating water you won’t use. We’ll size your system based on how your family actually lives.

How long does water heater installation take in Exeter?

Most standard tank replacements are completed in two to four hours. GEM’s technicians arrive with a fully stocked truck, so we have the fittings, connectors, and parts needed to handle typical installations without delays. If your Exeter home requires modifications like updating old galvanized pipes, relocating the unit, or upgrading electrical service, the job may take longer. We’ll give you a realistic timeframe before we start.
