Venting and Draft Repair in Longmont, CO
Atmospheric gas water heaters depend on a properly sloped metal flue to carry exhaust out of the home. Disconnected sections, rusted draft hoods and poor slope can let combustion gases spill back.

Pilot Light Repair in Longmont
A pilot that will not light or will not stay lit is the most common gas water heater call. Causes include a worn thermocouple, a clogged pilot orifice, a bad piezo igniter or a tripped thermal cutoff. We test the thermocouple output with a meter and clean or replace the pilot assembly. Most pilot repairs are completed in about an hour.
Pilot Light & Burner Issues in Longmont
