Home Furnace Question

[Fish On! Guide Service]

I am a novice when it comes to this kind of thing and before I bite the bullet and get the repair man out to my home, I thought I'd try here first. I noticed this a.m. that my home furnace is making a moderately loud high-pitched whistling sound. The unit is a 90% H.E. Amana "Air command" gas furnace, approx. 10 years old. The whistling sound is audible only when the flame (not the pilot) is being produced. Filters are changed regularly fyi if that matters. Any folks out there have any suggestions as to what could be happening. Should I be concerned? Any suggestions as to what I might be able to try to remedy the situation? If this helps, I changed insurance companies recently and they sent a gentlemen out to my home to perform an inspection. I was with him while he looked at the furnace and he claimed everything looked extremely clean with no signs of rust, build up or condensation. Any and all help is welcomed.

Thanks,

Stephen

I'd guess that a jet or orifice may need cleaning or replaced. Pretty simple process.

I had a similar sound coming from the furnace in my new home. I ended removing the front cover and added weather stripping around the edge to help seal it up. Put her back on and now there's no more whistling sound when the furnace fires up.

Just thought I'd say thanks for the suggestions. I ended up taking a toothbrush and wirebrush to the orifices, or is it Orifi? and that cured the whistling sound. Thanks guys!
