A sudden loss of hot water disrupts your entire routine, turning simple tasks like showering, washing dishes, or doing laundry into major inconveniences.

At AirWorks Solutions, we specialize in diagnosing and repairing all models of tankless water heaters for homeowners and businesses throughout Ventura, ensuring you get your on-demand hot water back with minimal downtime. Our focus is on providing durable, professional repairs that address the root cause of the problem, not just the symptoms.
Common Tankless Water Heater Problems We Solve
Tankless water heaters are complex, and a variety of issues can cause them to malfunction. Our experienced AirWorks Solutions technicians have the diagnostic tools and expertise to identify and resolve any problem, including the most common ones in the Ventura area.
No Hot Water or Fluctuating Temperatures
This is the most critical symptom of a malfunctioning unit. The cause could be a failed ignition system in a gas model, a faulty heating element in an electric unit, or a clogged flow sensor that isn't properly detecting water movement. We systematically test each component to pinpoint the exact point of failure and perform a precise repair.
Low Hot Water Pressure
If you notice a significant drop in water pressure only when using hot water, the issue is likely within your tankless unit. Most often, this is caused by mineral and sediment buildup clogging the internal filters or the heat exchanger itself. This is a common problem in areas with hard water, and our service includes thoroughly cleaning these components to restore proper flow.
The Unit is Leaking
A leak, no matter how small, requires immediate attention to prevent water damage and more severe system failure. Leaks can originate from loose pipe fittings, a cracked heat exchanger, or a faulty pressure relief valve. Our technicians carefully inspect the entire unit to locate the source and secure or replace the compromised part.
Error Codes Displayed on the Unit
Modern tankless heaters use error codes to communicate specific problems. While these codes are helpful, they often point to a category of issues rather than a single failed part. Whether your unit is showing a code for ignition failure, a sensor malfunction, or an exhaust blockage, AirWorks Solutions has the brand-specific knowledge to interpret the code correctly and perform the necessary repair.
Strange Noises During Operation
Your tankless water heater should operate quietly. Loud banging, knocking, or rumbling sounds, often referred to as "kettling," are typically caused by a heavy accumulation of mineral scale on the heat exchanger. This forces the water to boil and steam within the unit, creating noise and putting immense stress on the components. Clicking or grinding noises may indicate a problem with the fan or another moving part.

The Decision: Repairing vs. Replacing Your Tankless Water Heater
When your system fails, you may wonder if a repair is the best financial decision or if it's time to invest in a new unit. AirWorks Solutions provides an honest, thorough assessment of your water heater's condition to help you make an informed choice that best suits your needs and budget.
When Repair is Often the Best Option:
- The unit is relatively new (under 10 years old).
- The issue is with a minor, replaceable component like a sensor, igniter, or valve.
- The unit has been regularly maintained and is otherwise in good condition.
- The cost of the repair is significantly less than the cost of a new installation.
When Replacement Should Be Considered:
- The unit is over 15 years old and nearing the end of its typical lifespan.
- You are experiencing frequent breakdowns and costly repairs.
- The heat exchanger, the most expensive component, is failing or leaking.
- The unit is improperly sized for your home's hot water demands.
- You want to upgrade to a newer, more energy-efficient model to lower your utility bills.

The Importance of Preventative Maintenance
The single best way to avoid unexpected breakdowns and extend the life of your tankless water heater is through regular, professional maintenance. Due to the mineral content in the Ventura water supply, annual flushing is essential. This process removes scale and sediment buildup that causes inefficiency, low pressure, and component failure. A maintenance visit also allows a technician to inspect all parts of your unit, catching small issues before they become expensive emergencies.
