Standing Pilot vs. IPI Systems - Why the Service Approach Differs
Standing Pilot Systems
A standing pilot system burns a continuous flame. It uses a thermocouple to hold the gas valve open. When the thermocouple wears out - typically after seven to ten years in a system used seasonally - the pilot extinguishes on release. Diagnosis is straightforward: light the pilot manually, hold the button, read the millivolt output. The number tells the story. Replacement parts for standing pilot systems are widely available and relatively consistent across brands. Many DFW homes built before 2010 still run this configuration.
IPI Systems
Intermittent Pilot Ignition (IPI) uses an electronic control module to ignite the pilot only when heat is called for. There's no continuous flame. The system clicks when activated, the pilot lights, and the main burner follows. When this system fails, there's no flame to test with a thermocouple reader. IPI diagnostic steps focus on the control module, the igniter electrode, and the wiring connections. Power source - battery or hardwired - is confirmed first. Then the spark gap is measured. Then the module's output signal is tested.
System Type Identification First
Post-2010 construction in Frisco, McKinney, and Allen is heavily IPI. A technician who runs a standing-pilot diagnostic on an IPI system won't find the fault. Knowing which system is in the fireplace before picking up a tool is step one of every call we run. We confirm the system type during the initial inspection - that determines the entire diagnostic and repair path.
Pilot Light Installation Cost in Dallas
Typical price ranges for pilot light installation across Dallas and the DFW Metroplex. Smaller, simpler jobs sit at the low end.
| Service | Typical price |
|---|---|
| Pilot assembly or thermocouple | $253 - $459 |
| Ignition module replacement | $325 - $619 |
| New pilot systemValve plus pilot, or full gas system repair | $1,349 - $3,800 |
| Manual lighting solution | $485 |
Your exact price is confirmed on site before any work starts. Smaller, simpler jobs sit at the low end of each range. Our $79 chimney safety inspection is waived when you book the repair.
FAQ
What does it cost to have a gas fireplace pilot light diagnosed and repaired?
Call 972-884-5553 for current rates. Diagnostic cost varies based on system type (standing pilot vs. IPI), the failed component identified, and whether parts are needed. Testing before replacing anything means you're quoted only for what actually failed - not for parts replaced by assumption.
How long does a pilot light service call take?
Most pilot light diagnosis and repair visits take 60 to 90 minutes. Standing pilot thermocouple replacements are typically faster. IPI system diagnostics take longer because the ignition module, electrode, and wiring harness are each checked in sequence. Your technician will give you a time estimate after identifying the system type - before any work begins.
What's the difference between a thermocouple and a thermopile - and which one does my fireplace have?
A thermocouple is a single heat-sensing wire that keeps the gas valve open while the pilot burns. A thermopile is a larger sensor that generates enough voltage to power the gas valve without a separate power source. Most older standing pilot gas fireplaces use a thermocouple. Fireplaces with wall switches or remote controls often use a thermopile. Your technician identifies which system is installed during the diagnostic step - before any parts are recommended.
My pilot light worked fine last year - why would it fail now after just sitting unused?
Six or more months of inactivity is the most common cause of thermocouple failure in DFW gas fireplaces. Dust accumulates on the pilot orifice. Condensation forms inside the gas valve seat. Thermocouple tips oxidize when not kept warm by a continuous flame. None of these show up as warning signs - the system simply stops holding when you need it in November.
