Signs Your Water Heater Needs Immediate Repair:
Listen to Your Water Heater:
Loud rumbling, popping, or banging sounds indicate sediment buildup at the tank bottom, causing heating elements or burners to overheat. Hissing suggests leaks or pressure problems. Strange noises don’t resolve themselves, they escalate until complete failure occurs.
Watch Water Quality:
Rusty or discolored hot water signals tank corrosion, while cloudy water indicates sediment accumulation. Foul odors suggest bacterial growth in the tank. These problems affect your family’s health and indicate the water heater needs professional attention.
Notice Performance Changes:
When showers turn cold halfway through, your morning routine gets interrupted, or multiple family members can’t use hot water consecutively, your water heater isn’t meeting household demands. This inefficiency costs money through wasted energy while failing to provide adequate comfort.
Check Around the Unit:
Water pooling beneath your water heater indicates leaks that can flood your home within hours. Even small leaks waste water, damage surrounding areas, and signal failures requiring immediate professional assessment. Never ignore water around your heater.
Monitor Your Bills:
Unexplained increases in gas or electric bills often trace to water heater inefficiency. Failing heating elements, sediment buildup, or thermostat problems force systems to work harder, consuming more energy while providing less hot water.
Our Water Heater Repair Process:
Thorough Diagnosis:
Our licensed plumbers inspect your entire water heater system, testing heating elements, thermostats, pressure relief valves, gas connections, and checking for leaks or corrosion. We identify root causes rather than just treating symptoms.
Clear Explanation:
We explain what’s wrong in plain language, show you the problem when possible, and discuss your options. You’ll understand whether repair makes sense or if replacement provides better long-term value for your specific situation.
Quality Repairs:
We use manufacturer-approved parts and proper repair techniques that restore reliable operation. Our work meets code requirements and comes with warranty protection, giving you confidence in repairs that last.
Preventive Recommendations:
After repairs, we discuss maintenance practices that prevent future problems, signs to watch for, and realistic expectations about your water heater’s remaining lifespan based on its age and condition.
Water Heater Installation & Replacement
Expert Installation for Reliable Performance
When Replacement Makes More Sense Than Repair:
Age Considerations:
Water heaters typically last 8-12 years depending on water quality, maintenance history, and usage patterns. Beyond 10 years, repairs often prove temporary fixes before the next component fails. Replacement eliminates the cycle of escalating repair costs.
Cost Analysis:
When repair costs exceed 50% of replacement cost, especially for older units, replacement provides better value. You get a new warranty, improved efficiency, and years of reliable service rather than nursing an aging unit through repeated failures.
Efficiency Upgrades:
Modern water heaters operate significantly more efficiently than units installed even 10 years ago. Tankless models, heat pump water heaters, and high-efficiency tank models reduce energy consumption substantially, often offsetting replacement costs through utility bill savings.
Capacity Changes:
Growing families, home additions, or lifestyle changes may mean your current water heater no longer meets household needs. Replacement allows right-sizing for actual hot water demand rather than struggling with insufficient capacity.
Water Heater Types We Install:
Traditional Tank Water Heaters:
Tank water heaters store 30-80 gallons of hot water, providing reliable hot water supply at the most economical initial cost. Available in gas and electric models, they work well for most homes and offer proven technology with straightforward maintenance requirements.
- Gas Tank Water Heaters: Faster recovery rates, lower operating costs in most areas, ideal for homes with natural gas service
- Electric Tank Water Heaters: Simple installation, no venting required, works in any home, precise temperature control
Tankless Water Heaters:
Tankless systems heat water on demand rather than maintaining a tank of hot water. They provide endless hot water, occupy minimal space, and operate more efficiently than tank models. Higher upfront costs offset through energy savings and longer lifespan (15-20 years).
- Gas Tankless Water Heaters: Highest flow rates, best for larger homes, requires proper venting
- Electric Tankless Water Heaters: Simpler installation, lower upfront costs, works well for smaller homes or supplemental applications
Heat Pump Water Heaters:
These units use electricity to move heat rather than generate it, providing exceptional efficiency in suitable climates. They work best in spaces with excess heat and adequate surrounding space, offering 2-3 times the efficiency of conventional electric water heaters.
Hybrid Water Heaters:
Combining tank storage with heat pump technology, hybrid units provide both efficiency and storage capacity. They work well for families needing substantial hot water volumes while wanting energy savings.
Our Installation Process:
Proper Assessment:
We evaluate your home’s hot water needs based on family size, simultaneous usage patterns, available space, and utility services. This assessment ensures we recommend the right type and size for your specific situation.
Code Compliance:
All installations meet current building codes and manufacturer specifications. We handle required permits, install proper venting for gas units, ensure adequate electrical service, and install expansion tanks and other safety devices per code requirements.
Professional Installation:
Our licensed plumbers properly connect water, gas, and electrical services, test all safety devices, set correct temperatures, and verify proper operation before completing the job. We explain operation, maintenance requirements, and warranty coverage.
Old Unit Removal:
We disconnect and properly dispose of your old water heater according to local regulations, leaving your installation area clean and ready for immediate use.
Tankless Water Heater Specialists
Endless Hot Water and Energy Efficiency
Benefits of Tankless Water Heaters:
Endless Hot Water Supply:
Tankless systems heat water continuously as it flows through the unit, eliminating the “running out of hot water” problem that plagues tank systems. Back-to-back showers, filling large tubs, and simultaneous hot water use throughout your home become possible.
Energy Efficiency:
By heating water only when needed rather than maintaining a tank of hot water 24/7, tankless systems reduce energy consumption by 24-34% for typical households. This efficiency translates to lower utility bills throughout the unit’s 15-20 year lifespan.
Space Savings:
Wall-mounted tankless units occupy minimal space compared to bulky 40-80 gallon tanks. This frees valuable floor space in utility rooms, closets, or garages for other uses.
Longer Lifespan:
While tank water heaters last 8-12 years, tankless units typically operate reliably for 15-20 years with proper maintenance. This longevity offsets higher initial costs through extended service life.
Cleaner Hot Water:
Without a storage tank where sediment accumulates and bacteria can grow, tankless systems provide cleaner hot water throughout their service life.
Tankless Installation Considerations:
Proper Sizing:
Tankless units must be sized correctly for your home’s peak hot water demand. We calculate required flow rates based on simultaneous fixture use to ensure adequate hot water supply during high-demand periods.
Utility Requirements:
Gas tankless units require adequate gas line sizing and proper venting. Electric tankless systems need sufficient electrical capacity, often requiring service panel upgrades. We evaluate your home’s utilities during assessment to ensure proper installation.
Temperature Rise:
North Texas groundwater temperatures affect tankless performance. We account for seasonal variations and your desired output temperature when recommending appropriate models.
Maintenance Needs:
Tankless systems require annual descaling in areas with hard water to prevent mineral buildup affecting performance. We explain maintenance requirements and offer service plans that protect your investment.

Frequently Asked Questions
Traditional tank water heaters last 8-12 years on average, while tankless systems typically provide 15-20 years of service. Lifespan depends on water quality, maintenance history, and usage patterns. Hard water shortens lifespan without proper maintenance.
Tank water heater sizing depends on household size and peak usage. A family of 2-3 typically needs 40-50 gallons, while families of 4-5 require 50-80 gallons. Tankless sizing depends on simultaneous fixture use and desired temperature rise. We calculate proper sizing during our assessment.
Tankless systems cost more upfront but offer energy savings, longer lifespan, and endless hot water. For families frustrated by running out of hot water or looking to reduce energy costs long-term, tankless systems provide excellent value. We help you analyze costs versus benefits for your specific situation.
Rumbling or popping sounds typically indicate sediment buildup at the tank bottom, causing heating elements or burners to overheat. Hissing suggests pressure problems or leaks. Banging may indicate water hammer or loose components. Professional diagnosis identifies the specific cause and appropriate solution.
While some maintenance tasks like adjusting thermostats are DIY-friendly, most repairs require professional expertise. Gas water heaters involve combustion safety, while all water heaters involve high-temperature water under pressure. Improper repairs create safety hazards and may void warranties.
Annual maintenance for tank water heaters extends lifespan and maintains efficiency. Tankless systems benefit from annual descaling, with hard water areas potentially requiring twice-yearly service. Our Advantage Plan includes annual water heater maintenance plus other critical home services.
Rust in hot water usually indicates tank corrosion, often meaning replacement is necessary soon. Sometimes rusty water comes from corroded anode rods, which can be replaced. We diagnose the source and recommend appropriate action based on your water heater’s age and condition.
Several factors cause this problem: undersized water heater for household needs, failing heating elements, incorrect thermostat settings, heavy sediment buildup reducing tank capacity, or dip tube failures allowing hot and cold water to mix. Professional diagnosis identifies the specific cause.
We recommend 120°F for most homes, balancing safety, comfort, and efficiency. Higher temperatures increase scalding risks, especially with children or elderly family members, while also wasting energy. Lower settings may not provide adequate hot water or may allow bacteria growth.
