When your water heater starts showing signs of age or stops working altogether, it's more than just an inconvenience - it affects your family's comfort and daily routine. A failing water heater can lead to cold showers, potential water damage, and higher energy bills.

Whether you need a conventional tank system or want to explore the benefits of a tankless water heater, our licensed and insured technicians are here to provide you with premier solutions tailored to your specific needs. We know that choosing a new water heater involves more than just picking a unit - it's about understanding what will work best for your home, your budget, and your long-term goals.
Understanding Your Water Heater Needs
Before jumping into a replacement, it's important to understand what you're working with. Most homes in Garland rely on one of two types of water heater systems - conventional tank-style heaters or tankless systems. Each has its own advantages, and the right choice depends on your household's hot water demands, available space, and energy efficiency goals.
A conventional water heater stores heated water in a tank, typically holding 40 to 80 gallons. This means hot water is always ready when you turn on a faucet or shower, but the system continuously heats the water in the tank to maintain temperature. Tankless water heaters, on the other hand, heat water on demand as it flows through the unit. This approach eliminates the need for a storage tank and provides hot water continuously without the wait.
Understanding these differences is the first step in making an informed decision about your replacement. Our team at Mack's Plumbing is dedicated to providing top-notch explanations of your options so you can feel confident about what you choose.
Signs Your Water Heater Needs Replacement
Recognizing when it's time to replace your water heater can save you from unexpected breakdowns and water damage. Here are the most common indicators that replacement is the right move:
- Age of the unit: Water heaters typically last 8 to 12 years. If yours is approaching or past this age, replacement is often more cost-effective than repairs.
- Rusty or discolored water: This can indicate corrosion inside the tank, which means leaks are likely to follow.
- Leaking from the base of the unit: A leak is a clear sign that the tank has failed and replacement is necessary.
- Strange noises or rumbling: Sediment buildup inside the tank causes these sounds and reduces efficiency.
- Inconsistent hot water supply: If you're running out of hot water quickly or the temperature is erratic, the heating element may be failing.
- Visible rust or corrosion on the exterior: This suggests the unit is deteriorating and replacement should be prioritized.
- Higher energy bills without explanation: An aging water heater works harder to maintain temperature, consuming more energy.
If you're experiencing any of these issues, it's time to contact a professional to evaluate your system. We can inspect your current unit and discuss whether repair or replacement makes the most sense for your situation.
Conventional Water Heaters vs. Tankless Systems
When it comes time to replace your water heater, one of the biggest decisions you'll face is whether to stick with a conventional tank system or upgrade to a tankless model. Both have distinct advantages, and the right choice depends on your specific circumstances.
Conventional Tank Water Heaters
Conventional systems have been the standard in homes for decades, and they remain a reliable choice for many households. These units work by heating and storing water in an insulated tank, keeping it ready for use throughout the day and night.
Advantages of conventional systems:
- Lower upfront cost compared to tankless models
- Simple installation process in most homes
- Reliable performance with proven technology
- Easier to repair with readily available parts
- Works well for households with multiple simultaneous hot water needs (like running the shower while someone uses the washing machine)
- No special venting requirements in many cases
Conventional systems are particularly well-suited for families in Garland who have established plumbing infrastructure and are looking for a straightforward replacement solution. If your current installation is a conventional system, staying with this option often means minimal adjustments to your existing setup.
Tankless Water Heaters
Tankless systems represent a shift toward more efficient hot water delivery. Rather than storing heated water, these units heat water on demand as it passes through a heat exchanger. This approach appeals to homeowners looking to reduce energy consumption and enjoy some unique benefits.
Advantages of tankless systems:
- Significantly lower energy consumption, often reducing water heating costs by 20-30%
- Endless hot water supply without the tank limiting volume
- Takes up much less space - ideal for homes where closet or utility room space is limited
- Longer lifespan, typically 15-20 years or more
- Lower standby energy losses since water isn't being continuously heated
- Environmentally friendly option that reduces your carbon footprint
The main trade-off with tankless systems is higher upfront installation cost. However, many homeowners find that the long-term energy savings justify the initial investment. Garland residents interested in reducing their utility bills often find tankless systems worth considering, especially if they plan to stay in their home for many years.
Sizing Your New Water Heater
One of the most important factors in choosing a replacement water heater is ensuring the unit is properly sized for your household's needs. An undersized heater leaves you running out of hot water, while an oversized unit wastes energy and money. Getting the sizing right is crucial, and it's something our team takes seriously.
For conventional tank systems, sizing is based on the first-hour recovery rating and the peak hot water demand in your home. We evaluate your household's usage patterns - how many bathrooms you have, whether you have a large family, and your typical hot water needs throughout the day. A family of four typically needs a 50-60 gallon tank, while larger households might require 75-80 gallons.
Tankless systems require a different sizing approach. We calculate the maximum flow rate you'll need - measured in gallons per minute - based on your simultaneous hot water demands. For example, if you need hot water for a shower and washing machine running at the same time, we ensure the unit can handle that demand without a drop in temperature.
Proper sizing is one of the reasons we recommend having a professional evaluate your home rather than making assumptions based on the internet. Every household is different, and what works for your neighbor might not be ideal for your situation. Our technicians will walk you through this process step-by-step, ensuring your new water heater is perfectly matched to your needs.
The Water Heater Replacement Process
Understanding what happens during a water heater replacement can help you feel more prepared and reduce any anxiety about the project. The process is straightforward when handled by experienced professionals, though it does require careful planning and execution.
Step 1: Evaluation and Consultation
The process begins with a thorough evaluation of your current system and a discussion of your goals. Our team will inspect your existing water heater, check your plumbing connections, and ask questions about your hot water needs and preferences. This is the time to mention any concerns - whether you're interested in energy efficiency, want to free up space, or have budget considerations. We'll explain your options in plain language and help you understand the pros and cons of each choice.
Step 2: Ordering and Scheduling
Once you've decided on the system that's right for you, we'll order the unit and schedule your installation at a time that works with your schedule. We aim to minimize disruption to your daily routine, and our prompt and professional approach means the job gets done efficiently without unnecessary delays.
Step 3: Preparing the Installation Area
On the day of installation, our technicians will prepare your utility area. This includes protecting your floors and surrounding areas - we're respectful of your home, taking care to keep your space clean throughout the process. We'll shut off the water supply and drain your existing water heater safely.
Step 4: Removing the Old Unit
The old water heater is carefully disconnected from the plumbing lines, gas or electric connections, and venting if applicable. We handle the disposal of your old unit responsibly, ensuring it's recycled or disposed of properly according to environmental guidelines. This takes the burden off you - you won't have to figure out how to remove a heavy, potentially hazardous tank on your own.
Step 5: Installing the New System
Your new water heater is positioned in place, and all connections are made carefully and to code. For conventional systems, this includes connecting the cold water inlet, hot water outlet, drain, and either a gas line or electric connections. For tankless systems, we also ensure proper venting and may need to upgrade gas lines or electrical capacity if necessary.
Step 6: Pressure Testing and Safety Checks
Before we consider the job complete, every connection is tested for leaks and proper function. We verify that water pressure is correct, temperature settings are appropriate, and safety features are working properly. This attention to detail ensures your system will operate reliably from day one.
Step 7: System Activation and Walkthrough
Once everything checks out, we'll activate your new system and walk you through its operation. We'll show you how to adjust temperature settings, explain any special features, and answer any questions you have about maintenance or operation. We want you to feel confident and comfortable with your new water heater.
Why Licensed, Insured Professional Installation Matters
You might wonder whether DIY installation or hiring an unlicensed contractor could save money on water heater replacement. While that might seem attractive upfront, professional installation from a licensed, insured company like Mack's Plumbing offers important protections and benefits that far outweigh any short-term savings.
Proper installation ensures safety. Water heaters involve gas connections, electrical work, or high-temperature water - all of which can be hazardous if not handled correctly. Improper installation can lead to gas leaks, electrical hazards, or water damage. Our state-licensed technicians (License #M-39290) are trained and certified to handle these systems safely.
Installation done to code protects your home and warranty. Building codes exist for good reason - they ensure systems are safe and will function properly. Professional installation to code also protects your water heater warranty. Many manufacturers won't honor warranty claims if the unit wasn't installed by a licensed professional.
Licensed professionals carry insurance. If something goes wrong during installation, you have protection. Our insurance means you're not left bearing the cost of mistakes or accidents. This peace of mind is invaluable when you're making a significant investment in your home.
Experience prevents costly mistakes. Our team has completed hundreds of water heater replacements over 20 years. We know what to watch for, what common issues arise, and how to avoid expensive problems down the road. This expertise is something you simply can't get from an unlicensed contractor or DIY approach.
Energy Efficiency and Long-Term Savings
One of the most compelling reasons to replace an aging water heater is the opportunity to improve your home's energy efficiency. Water heating typically accounts for 15-20% of a home's energy consumption, so upgrading to a more efficient system can have a meaningful impact on your utility bills.
Modern conventional tank water heaters are significantly more efficient than older models, featuring better insulation and more effective heating elements. However, tankless systems represent an even greater leap in efficiency. Because they don't maintain a tank of hot water around the clock, they eliminate the energy waste of standby heating that conventional systems experience.
For Garland homeowners, the potential savings are substantial. With a tankless system, many families see energy bill reductions of 20-30% for water heating, which can translate to $300-500 per year in savings for some households. Over the 15-20 year lifespan of a tankless system, those savings add up significantly.
Beyond the direct energy savings, there are other financial benefits to consider. Federal tax credits have historically been available for upgrading to high-efficiency water heaters, though eligibility varies. Our team can discuss current incentives that might apply to your situation.
Warranty Coverage and Protection
When you choose Mack's Plumbing for your water heater replacement, you're not just getting installation - you're getting our 100% guarantee on repairs. We stand behind our work completely, and this commitment extends to your new system.
New water heaters come with manufacturer warranties that typically cover defects and performance issues. The length and coverage of these warranties vary by brand and model, so we'll explain exactly what's covered when we help you choose your unit. Most new systems come with at least a 6-year warranty on the tank or heating elements, with some premium models offering longer coverage.
Our installation warranty ensures that if any issue arises related to how we installed your system, we'll make it right. This means you can have complete confidence that your replacement was done properly and that we stand behind our work. This is part of what it means to work with a family-owned business that cares about protecting the health and wellbeing of the families we serve.
Financing Your Water Heater Replacement
We understand that water heater replacement represents a significant investment for many homeowners in Garland. That's why Mack's Plumbing offers flexible financing options designed to make your plumbing needs affordable and stress-free. Whether you're dealing with an emergency replacement or planning ahead, financing helps you manage the cost without compromising on quality.
Flexible financing means you can choose the option that works best for your situation. Rather than facing a large upfront cost, you can spread payments over time. This is particularly valuable if you're upgrading to a more efficient system - the monthly financing cost may be offset by energy bill savings from day one.
When discussing financing during your consultation, we're transparent about terms and options. There are no hidden fees or surprises - just straightforward information so you can make the best decision for your household's finances. We believe that protecting your home's plumbing shouldn't create financial stress.
Safe Disposal of Your Old Water Heater
When we remove your old water heater, we take responsibility for proper disposal. Old water heaters can't simply be thrown in the trash - they contain materials that should be recycled or disposed of according to environmental standards.
Our process includes safe draining of any remaining water, proper disconnection of all lines, and responsible recycling or disposal of the unit. You don't have to worry about arranging for bulk pickup or figuring out how to transport a heavy tank - we handle all of it as part of our service. This is just one of the ways we make the entire process as easy as possible for you.
Maintenance Tips for Your New Water Heater
After your new water heater is installed, a little routine maintenance can help it perform reliably for years to come. These simple steps can extend your system's lifespan and keep it operating at peak efficiency.
For conventional tank systems, drain a few gallons from the bottom valve annually to remove sediment buildup. This sediment reduces efficiency and can contribute to corrosion. Additionally, check the temperature and pressure relief valve periodically to ensure it's working properly - this safety feature is important and shouldn't be neglected.
For tankless systems, annual descaling is recommended in areas with hard water. Mineral deposits can accumulate in the heat exchanger, reducing efficiency. While this process is more involved than tank draining, it's still straightforward and helps maintain peak performance.
Regardless of which system you choose, keep the area around your water heater clear and accessible. This allows for proper ventilation and makes it easier to identify any potential issues early. If you notice any changes in performance, temperature consistency, or unusual sounds or smells, contact us promptly - early intervention often prevents more serious problems.
