Signs Your Water Heater Needs Service
Many homeowners don’t realize their water heater has a problem until it stops working. Here are some common warning signs that it may be time to call for service:
- Water takes too long to heat or runs out quickly
- Rust-colored or foul-smelling hot water
- Strange popping or rumbling noises from the tank
- Leaks around the water heater or visible corrosion
- A noticeable increase in your utility bill
These issues can worsen if left untreated. A prompt inspection can help avoid more significant repairs or premature replacement.
Fast, Reliable Repairs
Not all water heater problems require a new unit. Our technicians can often fix the issue with a cost-effective repair. Whether the thermostat needs adjustment, the heating element is failing, or sediment has built up inside the tank, we’ll get to the root of the issue and restore hot water fast.
Our service vehicles are stocked with parts for standard models, allowing us to complete most repairs the same day. We focus on saving you time and money while delivering lasting results.
Expert Installation & Replacement
If your water heater is over 10–12 years old, it may be time to consider replacement. We offer professional installation of high-efficiency water heaters that provide dependable performance and lower energy bills.
Our team will guide you through your options—gas or electric, tank or tankless—and help you choose the right size and type for your home. We handle every step of the installation process, including removing your old unit, connecting it to plumbing and power, safety testing, and final cleanup.
Tankless Water Heaters: Endless Hot Water, Lower Bills
Are you thinking about upgrading? Tankless water heaters are growing in popularity thanks to their energy efficiency and space-saving design. These systems heat water on demand, which means no storage tank and no running out of hot water.
We specialize in tankless water heater installation in Idaho Falls and can help you decide if this system is a good fit for your home. They’re ideal for larger families or homes with high hot water usage.
Preventative Maintenance to Extend Lifespan
Like any appliance, regular maintenance can significantly extend the life of your water heater. Our annual service includes:
- Flushing the tank to remove sediment and improve heating efficiency
- Inspecting the anode rod to prevent corrosion
- Checking the thermostat, pressure relief valve, and other safety features
- Looking for any signs of leaks, wear, or poor performance
Scheduled maintenance helps avoid unexpected breakdowns and ensures you get the whole life out of your system.
