    This is my 3rd year with my WaterFurnace GeoThermal unit. A couple weeks ago I had a odd pinging noise coming from the blower fan area of the unit. You can hear it echo through the duct work throughout the house. It is a ping with a temporary reduction in blower speed. It pings every few seconds for a span of a couple minutes. It will then return to normal fan speed without the ping for a few minutes and then go back to this pinging/flucuating fan speed cycle. A couple weeks ago this happened but it stopped after about 4 hours. Its been fine until this morning when it started again. I told my installer a couple weeks ago about this but he couldn't do much since the unit was back to normal. I am curious if this is a common enough problem that someone may recognize it. Below is a link to a posting of the sound on my facebook page. Hopefully the link works and thanks for the help.
