We had a Bryant furnace and a humidifier (General Aire Model 1042-LH) installed around 2003 or 2004. Everything worked fine until 2008. At which time the condensate pump to the humidifier started making a whirring noise. My furnace repair guy (from a heating and cooling place)tried to fix it, but said it was worn out and needed to be replaced. I spend over $189, just to have the new pump make a sump pump like noise a little over a year later. (I was also instructed to add vinegar to the pump to keep the parts moving, which I did on a regular basis.)
I called the furnace service guy back. On December 29, 2009, he took apart the condensate pump and said that there was a lot of sediment and debris, and cleaned it out. I asked if it was supposed to have that much gunk in it, and where was it coming from. He said that it wasn't supposed to have that much gunk in it, and perhaps the problem was coming from dirty air conditioning coils. (I also have a central air unit outside. I asked him what to do with the AC unit coils, but all he said was to add vinegar, about a 1/2 cup a year to the condensate pump, and to change the furnace filters often, which I do. He didn't mention anything about cleaning the coils, or if his company did that.) He also said that condensate pumps don't last long.
Everything worked fine for a month. It is now January 29 -- and the condensate pump is starting to make the sump pump noise again. I called the maker of the humidifier, who told me that it shouldn't make that kind of noise, and to call the furnace guy back.
I'm tired of spending money that I don't have just to have the same problem occur again and again. What can I do to keep the condensate pump working and stop the gunk and sediment build up?
Any help will be appreciated. :)
