Burner Cleaning and Repair in Caldwell, ID
A yellow, lazy or noisy flame signals a dirty burner or poor combustion air. We remove and clean the burner, check the orifice size for natural gas or propane and adjust as needed. A clean blue flame heats faster and produces less carbon monoxide. We also check for rust flakes falling from the flue.

Thermostat & Gas Valve Repair in Caldwell, ID
If your gas water heater isn't heating water to the correct temperature, or if it is overheating, the thermostat or gas valve might be to blame. These components regulate the gas supply and temperature. Our plumbers in Caldwell, ID can test the thermostat for accuracy and inspect the gas valve for any blockages or malfunctions. We carry a range of replacement parts for various brands, allowing for quick and efficient repairs.
Restoring Hot Water for Older Homes in Caldwell
Many homes in Caldwell feature older gas water heater models that require specific knowledge for repair. Our technicians are familiar with the common issues and unique parts associated with these systems. We can troubleshoot and repair older units, often extending their lifespan, rather than pushing for immediate replacement. We focus on cost-effective repairs that respect the history of your home.
Flammable Vapor Sensor Repair in Caldwell
Most gas water heaters built in recent decades have a flammable vapor ignition resistant design. A sensor or flame arrestor screen shuts the burner down if it detects vapors or overheating. Lint and dust in garages can clog the arrestor and trip the system. We clean the combustion chamber and replace sensors or thermal switches as required.
Water Heater Tank Leaks and Pressure Issues in Caldwell, ID
While gas water heaters are sturdy, tank leaks or pressure problems can occur. We can often fix small fitting leaks or replace relief valves if pressure is too high. If the tank itself is compromised due to rust or old age, a replacement might be the more economical long-term solution. We will provide an honest assessment of the repair options for your Caldwell, ID home.
Pilot Light & Burner Issues in Caldwell
A common problem with gas water heaters is a pilot light that won't stay lit or a burner that fails to ignite. This can be caused by a faulty thermocouple, a dirty pilot tube or issues with the gas control valve. Our technicians in Caldwell are skilled at diagnosing these components and performing the needed repairs, whether it is cleaning, adjusting or replacing parts. We ensure proper gas flow and ignition for consistent hot water.
Burner Assembly and Venting System Repair in Caldwell
A worn burner assembly can result in insufficient heating or unusual noises. We carefully inspect the burner for blockages, corrosion or wear. We also check the venting system for proper draft and obstructions, which is vital for safe operation and preventing carbon monoxide buildup in your Caldwell home. Proper venting is a key safety consideration.

Tank Leaks and Pressure Problems in Caldwell
Even gas water heaters can develop tank leaks, often due to corrosion from hard water or high water pressure. Many Idaho homeowners use water softeners to extend the life of their tank water heaters, faucets, and appliances against mineral buildup. While some leaks might require a replacement, minor leaks or pressure relief valve issues can often be repaired. Our team checks the extent of the damage, inspects the anode rod and addresses pressure imbalances to prevent further problems in your Caldwell home.
