.... Also, this unit is a heat pump, they need to be placed in the open and certainly without an enclosure above it to be able to maximize the heating efficiency. As the heat pump operates it absorbs heat from the air, the discharge air coming from the top needs to be released and carried away naturally. Having a structure above and around the unit will trap this cool air and create a "cold zone" around it, allowing the already processed cool air to be re-circulated, decreasing efficiency.
The solution is to find a new location for the unit. Away from concrete or stone work if possible. Place it in the open air so sound waves can project upwards, but don't place it underneath a window if possible. it should be a minimum of 24" from the building.
The problem is sound resonance. The unit is sitting directly on a concrete slab, It is covered by a porch/deck (trapping the sound waves that are projected upward through the top fan opening of the unit and bouncing them back down to the concrete. All condensing units are designed to project this sound upward into the open air, they should NEVER be placed under any structure) The chimney is cinder block that conducts this sound up into your living room....hence the buzzing noise you are hearing.
Are those the same muppets that carried out previous on your behalf? You sholdn't be going through Heatpumps for a Pastime... No one could hold out to replacment of same nearly every year....
Doesn't seem to be installed to any Code.. landing same on your porch slab on your covered walkway also this newly installed heatpump has warranty on the installation get those suckers back out there pay a few Dollars arm yourself with a report from a Certified Air conditioning Commisioning Engineer setting out proper site location..landing same onto this concrete slab doesn't help plus antivibration dampers may also needed fitting, as this vibration will cause fractures in soldered fittings
I see this all the time. move the unit from under the cover on a seperate slab not attached to the home. You can buy prefab slabs from any ac aupply store.
another comment: most problems stem from bad installation when they are re-occuring. If someone just replaces the outdoor and/or indoor units and use the same line set (refrigeration lines), then there could be a problem with the lines itself. (kink, or clogged due to bad brazing skills)
It's hard to comment with just that factor. You diagnose a system with a lot of other values aside by sight glass and noise. You must measure some values and send some specs as well. example: model, serial no. refrigerant, voltage , amps, RLA, LRA, charge, then measure DB & WB temps., superheat and subcooling, voltage, amps, as much as you can gather, and post it for answers, not this way, you will get a lot of guess work.

Very interesting heat pump video. Thanks for sharing.
