Precision diagnostics for residential hot water boilers, addressing pump failures, kettling, and radiator issues.
Call For Service: (737) 282-0678While forced air is the norm in Central Texas, several older and custom homes in Elgin rely on hydronic boiler systems for radiant heat. Boiler repair requires a specific skill set that many standard HVAC techs lack. Whether you have a cast-iron conventional boiler or a wall-hung modulating combi-boiler, we understand water temperature differentials, zone valve operation, and how to balance the system so your baseboards or radiators deliver even, quiet heat.
A boiler relies on a delicate balance of water pressure and temperature. A failed expansion tank or a stuck pressure relief valve can cause the boiler to lock out completely or, worse, cause a dangerous pressure buildup.
A leaking pressure relief valve is a serious warning sign. Shut off the boiler and call (737) 282-0678 immediately to prevent severe water damage or a cracked block.
Skip the forms and wait times. Speak directly with an Elgin HVAC specialist to troubleshoot your system or schedule immediate dispatch.
Each service call includes a thorough multi-point inspection to find and fix the root cause:
Verify static and operating water pressure
Test circulator pump amp draw and flow
Check expansion tank bladder integrity
Inspect aquastat and high limit controls
Bleed air from highest points in the loop

Call (737) 282-0678This is often kettling, caused by mineral scale buildup restricting water flow, or it could be trapped air expanding rapidly inside the pipes.
That is the pressure relief valve. It leaks when the system pressure exceeds safe limits (usually 30 PSI), often due to a failed expansion tank or auto-fill valve.
It\'s a good practice, especially if you have a conventional system, to release trapped air that prevents the hot water from fully circulating.
Yes, we diagnose and repair modern high-efficiency condensing boilers like Navien or Lochinvar, including domestic hot water issues.
Many prefer hydronic heat because it doesn\'t blow dust around and provides a very consistent, gentle warmth, though the systems are more expensive to install.
