We Service All Types of Water Heaters in Lehigh Valley
At Andreas Plumbing, Heating & Air Conditioning, we have experience repairing and maintaining all types of water heaters. No matter what kind of unit you have, our skilled technicians can diagnose and fix issues quickly so you can continue enjoying an uninterrupted supply of hot water.
Conventional Water Heaters
Conventional water heaters store water hot in a tank, ready for use when needed. These units can experience sediment buildup over time, leading to reduced efficiency, temperature fluctuations, and frequent repairs. Our team offers routine maintenance to extend the life of your unit and ensure it’s functioning properly.
Tankless Water Heaters
Tankless water heaters provide hot water on demand without the need for a storage tank, making them a more efficient system for homeowners looking to reduce energy costs. If your tankless unit isn’t heating properly, our technicians can troubleshoot and repair issues related to supply lines, low water pressure, and failed burners to restore optimal performance.
Gas Water Heaters
A gas water heater uses natural gas to heat water, making it an energy-efficient choice for many homes. However, these units require regular servicing to prevent sediment buildup. Part of our water heater services includes checking the pilot light, searching for leaks, and flushing the tank for maximum safety and efficiency.
Electric Water Heaters
Electric water heaters use electricity to heat water and typically require less maintenance than gas models. However, issues like faulty thermostats, tripped breakers, or heating element failure can impact performance. Our team can diagnose electrical issues and perform hot water heater repairs to get your system back up and running.
Signs Your Water Heater May Need Repairs
A failing water heater can cause major disruptions in your daily routine. If you notice any of the following issues, it may be time to call for professional water heater repair service:
- Lack of Hot Water: If your water heater isn’t providing enough hot water or runs out too quickly, you may have a failing heating element, sediment buildup, or an undersized unit.
- Strange Noises: Rumbling, banging, or popping sounds often indicate sediment buildup inside the tank, which reduces efficiency and may cause premature wear.
- Discolored or Smelly Water: Rusty or foul-smelling hot water can signal corrosion inside the tank or bacterial growth, requiring immediate attention.
- Leaks Around the Unit: Water pooling around your hot water heater could be due to a failing pressure relief valve, thermal expansion, or cracks in the tank itself.
- Inconsistent Water Temperatures: If you experience temperature fluctuations, a faulty thermostat or heating element could be to blame.
- Increased Energy Bills: A failing water heater often works harder to heat water, leading to higher energy bills.

Water Heater Repair and Replacement: What’s More Cost-Effective?
If your water heater is acting up, you may be wondering whether water heater replacement or repair is the better option. In many cases, minor repairs can restore your unit’s performance and extend its lifespan. However, if you find yourself dealing with frequent repairs or a system that’s more than 10 years old, investing in a new water heater could be the wiser choice.
A water heater installation can lead to energy savings and lower utility bills over time. Upgrading to a tankless unit or a high-efficiency model may also qualify you for rebates or incentives. Our team will assess your system and help you decide whether a hot water heater repair or replacement service is the best solution for your home.
Tankless Water Heater Repairs
Tankless water heaters are known for their energy efficiency, but like any appliance, they can develop issues over time. Common problems include temperature fluctuations, low water pressure, and mineral buildup. If your unit isn’t delivering an uninterrupted supply of hot water like it’s supposed to, our experienced technicians can quickly diagnose and resolve the issue.
Regular water heater maintenance helps prevent costly breakdowns and ensures your tankless unit operates at peak performance. Whether you need routine maintenance, descaling, or a major repair, our team is here to keep your system running smoothly.
Water Heater Troubleshooting Tips for Homeowners
Before calling for water heater repair services, try these troubleshooting tips:
- Check the Power Supply: Make sure your electric unit’s breaker hasn’t tripped, or the gas supply is on for natural gas models.
- Inspect the Thermostat: Adjust the temperature setting if your hot water is too hot or not hot enough.
- Flush the Tank: Draining the unit helps remove sediment buildup, improving efficiency.
If these steps don’t resolve the issue, call us for expert plumbing service.
