Common Water Heater Problems We Fix
Experiencing hot water issues? We diagnose and repair all water heater problems:
No Hot Water
Complete loss of hot water can be caused by failed heating elements, broken thermostats, pilot light issues, or electrical problems. We diagnose the cause and restore your hot water quickly.
Water Heater Leaking
Leaks from the tank, relief valve, or connections require immediate attention. We determine if repair is possible or if water heater replacement is necessary.
Not Enough Hot Water
Insufficient hot water or water that runs out too quickly indicates sediment buildup, undersized unit, or failing heating elements. We restore your system’s capacity.
Strange Noises
Water heater making noise like popping, banging, or rumbling sounds typically means sediment accumulation. Our maintenance service eliminates these issues.
Pilot Light Issues
Pilot light won’t stay lit or keeps going out on gas water heaters? We repair or replace thermocouples, gas valves, and control systems.
Rusty or Smelly Water
Rusty hot water or smelly hot water indicates anode rod failure or bacterial growth. We replace anode rods and flush systems to restore water quality.
Relief Valve Dripping
Water heater relief valve leaking signals excessive pressure or temperature. We diagnose the root cause and make necessary repairs.
Cold Water Only
Getting only cold water from taps? We check thermostats, heating elements, gas supply, and electrical connections to restore function.

Tank vs Tankless Water Heaters: Which is Right for You?
Choosing between a traditional tank water heater and a tankless system? Here’s what you need to know:

- Risk of tank rupture and flooding
Tankless Water Heaters
On-demand systems heat water only when needed, providing endless hot water.
Advantages
- Unlimited hot water supply
- Energy savings (20-40% less energy)
- Longer lifespan (15-20+ years)
- Space-saving compact design
- No tank to leak or rupture
- Lower long-term operating costs
Disadvantages

Water Heater Questions Answered
Water heater installation cost varies based on system type, fuel source, and complexity. Tank water heater installations are typically less expensive. Tankless water heater installations are more expensive due to additional requirements like gas line upgrades and venting. We provide free, detailed estimates with no obligation.
Water heater replacement cost depends on your current setup and the new system you choose. Like-for-like tank replacements are most affordable. Upgrading to tankless or switching fuel types costs more due to additional work. We offer competitive pricing and can work within your budget. Contact us for a free replacement estimate.
Consider water heater replacement if your unit is 10 years old or older (tank) or 12 to 15 years old (tankless), requires frequent repairs, has visible rust or corrosion, is leaking from the tank, or isn’t meeting your hot water needs. We can assess your system’s condition and help you decide if repair or replacement makes more financial sense.
Water heater size depends on your household size and hot water usage. For tank systems, we recommend 40-50 gallons for 1-2 people, 50-60 gallons for 2-3 people, and 60-80 gallons for 4+ people. For tankless systems, we calculate based on simultaneous hot water demand and flow rates. We provide proper sizing calculations to ensure you have adequate hot water.
Common causes when a water heater is not working include tripped circuit breakers or blown fuses (electric), pilot light out (gas), faulty thermostats, failed heating elements, sediment buildup, or gas supply interruptions. Our technicians diagnose the exact cause and provide solutions quickly.
Water heater repair cost varies by the problem. Older units and repairs exceeding 50% of replacement cost may indicate it’s time for a new unit. We provide upfront repair estimates before proceeding. Give us a call or send us a text.
We recommend annual water heater maintenance for optimal performance and longevity. Regular service includes flushing sediment, checking the anode rod, testing safety valves, and inspecting for leaks. Tankless systems require annual descaling in areas with hard water. Proper maintenance extends your water heater’s lifespan and prevents costly breakdowns.
A water heater making noise (popping, banging, rumbling) typically indicates sediment buildup at the bottom of the tank. As water heats, it becomes trapped under the sediment and causes these sounds. Our flushing service removes sediment and eliminates noise. Other noises may indicate loose heating elements or high water pressure—we diagnose and fix all noise issues.
Tankless water heaters cost more upfront but offer significant long-term value: 20-40% energy savings, unlimited hot water, space savings, and 15-20+ year lifespan versus 8-12 years for tanks. For families with high hot water demand or those planning to stay in their home long-term, tankless systems often pay for themselves through energy savings and avoided replacement costs.
