The thermocouple is a copper rod that the pilot flame heats-up. When it gets hot enough, the thermocouple signals that there is enough heat to burn the gas fuel being released into the appliance—and so it allows the gas to be released to the burners. In some cases where the pilot light won’t stay lit, the thermocouple needs to be adjusted or replaced. This is generally a job for a professional.

Furnace Repair Company


To keep your natural gas furnace operating efficiently, you should have at least an annual tune up. Natural gas furnace preventative maintenance will help avoid operating problems. When issues are addressed early on, it’s more likely that they can be resolved with minimal cost. Worn out parts and clogged filters that happen over time can lead to more significant equipment failures.

The oil filter (found in oil-powered systems only) prevents small impurities from clogging the oil-burner nozzle, which could result in a misfire that shuts down the system. Richard first closes the oil valve, then removes the old filter and replaces it, setting aside the dirty filter to be disposed of according to local hazardous-waste regulations.
A pinging or popping sound coming from the duct work can come from thermal expansion—the ductwork expanding and contracting as it heats and cools.  Or, air blowing past a loose flap of metal can make the sound. Track along the duct runs, listening for the sound. If you locate it, make a small dent in the sheet metal to provide a more rigid surface that’s less likely to move as it heats and cools.
Great article! I am having trouble identifying what to use for the aluminum or zinc strips to prevent organic growth and staining. How wide are the strips? Are they predrilled? I am starting to see black stains on the north facing asphalt shingles. Do you recommend treating that befor adding the metal strips? If so, 50/50 bleach and water or a commercial product?
