A functioning water heater is essential to your home or business. Whether your current water heater is leaking or not giving hot water, or you’re being proactive and looking to upgrade, Aaron Plumbing can help you determine whether you need a water heater repair or replacement, and walk you through the next steps. Trust our Peace of Mind Promise.

Water Heater Repair Options:

When a water heater stops working (or starts leaking!), it’s important to address the problem quickly. Water heaters can flood homes and no hot water can be a major inconvenience.

Water Heater Diagnosis – Can It Be Repaired?

An Aaron Plumbing plumber will begin by diagnosing the problem. Depending on the symptoms you are experiencing, your technician will examine the water heater, find the source of any leaks, evaluate electrical connections, and, when necessary, assess thermostats, heating elements, or gas valves. Once your plumber has identified the cause of the problem you’re experiencing, we’ll be able to move on to the solution.

Part Replacements When Possible

Once we have found the problem, it may be possible to replace a part on your water heater. Whether or not part replacement is an option depends on a number of factors, including the age of the water and whether there are any other malfunctioning parts. Electric water heaters may need new heating elements, wiring, or thermostats. Gas water heaters could need a replacement thermocouple, gas valve, or pilot assembly. Sometimes we’re able to avoid a full replacement by changing out a particular water heater part.

Always Check the Pressure

Properly regulated pressure is extremely important. High pressure can show itself at your water heater. If there’s a pipe coming from your water heater that is releasing water, this may be a sign that you have a pressure problem. Your technician will ensure that your pressure regulating valve is working properly. They will also inspect your expansion tank and your temperature and pressure line.

Water Heater Replacement Options:

Sometimes a water heater replacement will be the best option for your home or business. If the water heater has not been performing well for you, is older, or cannot be repaired, a water heater replacement will be the most appropriate choice.

Aaron Plumbing will walk you through your options (we offer both tank and tankless water heaters) and help you choose the best water heater for you.  Here’s a walkthrough of the Aaron Plumbing water heater replacement process:

A Thourough Evaluation

One of our experienced, professional Aaron Plumbing technicians will examine your old water heater, and evaluate your needs. They’ll check for any code compliance issues or safety concerns. They’ll also listen to your description of your hot water needs.

Finding the Right Water Heater for You

If we determine that a water heater replacement is best, our technician will walk you through your options in choosing a new water heater. We’ll consider the size of your old tank, energy efficiency rating, whether you’ll need electric or gas, code requirements, and the available space. Your technician will help you choose the best water heater for you.

The Replacement Process

Your technician will disconnect, drain and remove your existing water heater. We will then install the new water heater, including running and/or connecting all necessary water, gas and venting. Water heater installation requires a professional. Because water heaters involve electricity or gas, pressurized water, and venting of dangerous gasses, it’s important to hire a professional to complete this work.

Ensuring Code Compliant, Quality Workmanship

We want our work to be inspected! Our plumbers complete professional, code compliant work. We pull permits for every water heater we install. Some counties complete and approve a water heater installation based on photos of specific aspects of the work, while others complete an in person inspection. We do leave the in person inspection to your discretion and schedule, but we pull permits on all water heater replacements because our workmanship is top notch and always code compliant.

Choosing the Right Water Heater for Your Home

If you’re in the market for a water heater replacement, choosing the right unit for your home is a crucial decision. With various options available, including tank and tankless water heaters, it’s important to understand the differences so that you make the best choice for your family’s needs.

Tank Water Heaters

Tank Water Heater Replacement

Tank Water Heaters are the traditional option most homeowners are familiar with. They store a large amount of hot water in a tank, typically available in 40-gallon or 50-gallon sizes. When deciding between the two, consider your household’s hot water demand. Larger families or homes with multiple bathrooms may benefit from the additional capacity of a 50-gallon tank. 50 gallons can supply hot water even during high usage periods. On the other hand, a 40-gallon tank may be sufficient for smaller homes or families with lower hot water usage.

Tankless Water Heaters

For homeowners looking to upgrade to a more energy-efficient option, tankless water heaters are an excellent choice. These units heat water on demand, providing an endless supply of hot water without the need to store it in a tank. However, choosing the right tankless water heater is not always straightforward. The size and type of tankless water heater depend on factors like your home’s water usage, the number of bathrooms, and the climate. It’s essential to have a licensed plumber assess your home’s hot water needs and recommend the best tankless water heater model for your setup.

Tankless Water Heater Replacement

Consider Safety

One critical consideration when replacing any water heater, whether tank or tankless, is the type of venting system required. Different models require different venting, and getting this wrong can lead to safety risks. For instance, power vent water heaters use a fan to exhaust gases through a horizontal vent. Atmospheric vent water heaters, in contrast, rely on natural airflow to vent gases vertically through a vent. We’ve seen instances where DIY enthusiasts or inexperienced handymen mistakenly replace power vent water heaters with atmospheric vent models. This mistake can lead to dangerous conditions, including improper venting of harmful gases.

For these reasons, it’s important to work with a professional plumber who can assess your home’s setup, determine the correct type of water heater, and ensure it’s installed safely. At Aaron Services, we offer free estimates for water heater replacements, so you can have peace of mind knowing you’ve made the right choice. Our experienced team will evaluate your home’s hot water needs, review your options, and provide expert guidance on the best solution.

An Interactive Water Heater Replacement Guide

In addition, we encourage you to visit our Water Heater Buying Guide for a comprehensive walkthrough of the decision process. This tool will help you consider factors like size, type, and energy efficiency. With it, you’ll find the best water heater for your home. Whether you’re leaning toward a tank or tankless model, the guide provides valuable insights to simplify your decision.

If you’re ready for a water heater replacement, contact us today to schedule a consultation. We’ll help you restore hot water to your home quickly and safely, ensuring your new water heater is installed properly to meet your family’s needs.

I’ve used this company since moving to the area in 2001, and they have consistently been outstanding in every aspect of service. They accurately assess the issue, clearly explain the recommended solution, and provide fair, transparent pricing. Most recently, Tai and Jeremy completed an all-day installation of a tankless water heater job for me. They went out of their way to customize the installation design to my specifications and were extremely accommodating and knowledgeable throughout the process. Everything was carefully designed and completed neatly and to code. Their customer service is exceptional—timely, professional, and transparent. I highly recommend them for quality work, fair pricing, and a level of service that is increasingly hard to find.

Great HVAC repair service from Aaron Services. From the initial and follow-up calls with Brenda and Missy in the office, scheduling was easy and everyone was friendly and professional. John Pool was on time, professional, and communicated throughout the entire appointment. He explained the issue and repair clearly and made the whole process easy and stress-free. I really appreciate both the office staff and his professionalism. Based on my experience, I wouldn’t hesitate to call Aaron Services again for any future Heating, Cooling, and Plumbing needs. 09/29/2026 - Aaron Services has done it again! Luke arrived right on time and did an incredible job explaining what was needed to bring our under-sink drainage up to Gwinnett County building code—correcting a faulty installation left behind by a previous plumber. His communication was top-notch, and the pricing was completely fair. To top it off, Missy called afterward to make sure we were 100% satisfied with the work. Aaron Services is my go-to for all plumbing and HVAC needs, and I wouldn’t trust anyone else with my home!
