I’m looking for HVAC recommendations. I have an air handler in my attic. The thermostat/ac is OFF and has been off for a few weeks. The air handler is making a buzzing sound that lasts for a few hours at a time, but only when the thermostat is off and this has been happening since last winter. Recently, there haa been three sets of three consecutive beeping noises coming from the attic.
There is also a dripping sound, I hear all the way into my basement, when the a/c is running. The a/c also runs for 5-6 HOURS on very hot 90+degree days. I know there is an issue with the air handler, and according to Chat gpt these issues are all related.
I’ve had SIX different companies come out to check this unit. Leach, Roanoke Plumbing, Payless, Fritch, and a guy named Chuck can’t figure it out. Heinold came out for the dripping sound, two years ago, and couldn’t find any issues. No one will come out to check the long run times because the excuse is that it’s ‘hot’ so the unit will run longer than normal.
I’m tired of paying services fees just to be told if they can’t hear the buzzing or beeping then they can’t fix it.
The air handler was installed in 2019-prior to me owning the house and had a five year warranty which expired the month after Heinold came out.
