Hello Everyone!
Let me start by saying that in May we had Ac tune up by "reputable company" here in Phoenix, and we were advised that our ac unit has to be "trashed" and new one put in place. I was really upset, since ac is about 13 years old, in a good working condition and electric bills were pretty consistent, with no surprises. My husband was pretty upset about me having this guy doing so called Tune up and after living in our home for 9 years, he told me that we can now expect to have problems with the unit, after we had a HVAC company on the roof with nobody else present.
After we said that there is no way we are replacing our rooftop unit, HVAC guy proceeded to tell us that coils need to be cleaned and that our capacitor is about to fail, which is something we expected, since we had it replaced previously, two years ago with non OEM part, and we already had a Rheem dual capacitor on hand, waiting on this one to die so we can replace it.
He served us a bill of almost a grand, said that he doesn't expect our ac to work much longer, we said thanks, but no thanks and he left. And what do you know? Two weeks later we started having issues with our AC. It started with very loud whistling noise coming from the vents, when ac comes on. This isn't your normal air blowing when ac is cooling, it's actually so loud that it will wake up entire household during the night, and you have to turn up the tv quite high in order to hear it. Ac continued to blow cold and turn on-turn off cycle works like it always did. Loudness the whistling will go up and down,like it gets muffled for a second or two.
Then last week, there started rumbling, where we can hear a thunder-like sound coming thru the vents along with a loud whistling we had previously. One half of the house is vibrating while ac is cooling, the other one has a whistle only. It's just crazy.
My husband went on the roof yesterday and found a crack with cold air escaping from the duct. He sealed it with some expandable foam, but that did not resolve our problem. I looked everywhere online for an answer and can't find any. Calling a professional right now is not an option due to financial difficulties. We are also in the talks with our bank trying to save our home from foreclosure, there is a hefty check from insurance company which is supposed to cover new ac duct and new roof due to hail damage back in 2010, but our attorney doesn't want us mailing that check to the bank until we have signed documents in our hands, so we really have no budget to have this looked at by HVAC guy. Could this be bent fan blades or faulty fan bearings? or could failing capacitor cause this kind of noise throughout the house? Any advice is welcome!
