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

How to Know When You Need a New Water Heater Installed

Know when your water heater is past its prime.

These warning signs are common throughout Marion. When they appear, GEM can assess whether replacement makes sense.

Water heaters typically last 8 to 12 years. Once yours approaches that range, performance declines and the chance of failure goes up. Replacing proactively means you choose when it happens.

Moisture around your water heater often signals a slow leak or tank corrosion. These issues only get worse over time. New water heater installation in Marion stops a small problem from becoming a flooded utility room.

If hot water temperatures vary unpredictably or the supply runs out faster than it used to, your water heater is losing capacity. Aging components and sediment buildup reduce performance over time.

An inefficient water heater uses more energy to produce the same amount of hot water. If your bills have crept up but usage hasn’t changed, your water heater may be the culprit. A new, efficient model brings those costs back down.

We Install All Types of Water Heaters in Marion

Every home has different hot water demands. GEM helps you choose the right water heater based on your household size, space, and budget.

Here’s a look at the types of water heaters we install in Marion:

Tank water heater installation in Marion is the tried-and-true choice for most households. These units store 40-80 gallons of heated water, ready whenever you need it. Tank models work with gas or electric power, install affordably, and deliver dependable performance for families running showers, laundry, and dishes throughout the day. For consistent hot water without surprises, a properly sized tank water heater gets the job done.

Tankless water heater installation in Marion appeals to homeowners who want endless hot water and energy savings. These compact units heat water on demand as it passes through, so you never run out mid-shower. Tankless systems mount on walls, freeing up floor space in tight basements or utility closets. GEM installs tankless water heaters in Marion homes looking for efficiency and long-term value.

Whether tank or tankless, today’s high-efficiency water heaters cut energy use without sacrificing performance. GEM installs ENERGY STAR certified models that qualify for rebates and lower your monthly utility bills. We’ll help you weigh upfront costs against long-term savings to find the smartest choice for your Marion home.

Water Heater Installation FAQs

What rebates are available for water heater installation in Marion?

Mass Save offers rebates on qualifying high-efficiency water heaters, including heat pump models that can significantly reduce energy costs. The rebate amounts vary by equipment type, and eligibility requirements change periodically. GEM stays current on available incentives and helps Marion homeowners identify which models qualify. We can also assist with the paperwork to make sure you capture available savings.

What size water heater do I need for my Marion 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 Marion 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.

When does it make more sense to replace my water heater instead of repairing it?

Three situations typically point toward replacement: age over 10 years, a leaking tank, or repair costs exceeding half the price of new equipment. In Marion’s historic homes and waterfront properties, we often see water heaters that have been patched multiple times but keep developing new problems. At that point, you’re throwing money at a system that’s fundamentally failing. GEM can help you weigh the costs and make the decision that’s right for your situation.

What if my water heater fails on a weekend or holiday?

GEM offers emergency service 7 days a week. Water heater failures don’t wait for convenient times, and neither do we. If your Marion home loses hot water on a Saturday night or holiday morning, call us. We’ll respond to restore your comfort.

What warranty should I expect on a new unit?

Tank water heaters typically come with 6 to 12 year manufacturer warranties, depending on model tier. GEM explains all warranty terms to Marion homeowners before installation begins.
