Signs Your Water Heater Needs Service

Don't ignore these warning signs. Early action can save you thousands in water damage.

Inconsistent Hot Water — Temperature fluctuates or you run out of hot water quickly during peak times.

Rusty Water — Discolored or rust-colored water from hot taps indicates internal corrosion.

Water Heater Leaks — Pooling water around the tank means internal corrosion or seal failure.

Strange Noises — Banging, popping, or rumbling sounds mean sediment buildup.

Rising Energy Bills — An aging water heater loses efficiency and costs more to operate.

Age of Unit — Water heaters typically last 8-12 years. Older units are at higher risk of failure.

Tank vs. Tankless Water Heaters

Not sure which system is right for you? We compare the two so you can make an informed decision.

Traditional Tank Water Heater

  • Stores hot water in an insulated tank (40-80 gallons)
  • Lower upfront installation cost
  • Well-established technology with many repair options
  • Takes up more space in utility room or basement
  • Uses energy to maintain tank temperature 24/7
  • 10-15 year lifespan
  • Good for households with consistent hot water demand

Tankless Water Heater

  • Heats water on-demand using gas or electric coils
  • Higher upfront cost, but saves 24-34% on energy
  • Compact, wall-mounted design saves space
  • Unlimited hot water supply for smaller households
  • Longer lifespan (15-20+ years)
  • No standby energy loss
  • Ideal for environmentally conscious homeowners

Our technicians can help you evaluate both options and recommend the best system for your home, budget, and hot water needs.
