So I called my company, they went out and found that there was low freon (~2lbs) but there was also a ton of grass/dirt on the outside compressor so they cleaned that as well and also did an extensive cleaning of the inside coils, checked for leaks both inside and out and found none.  

I have always been concerned they won't change them and cause excess wear on the compressor and an expensive repair/replacement.

I'm assuming there is already a forced air furnace and the $1850 is just for the compressor and coil.

The last thing you can do is listen and see if the condenser unit (the part outside with the compressor, condenser coils, and fan) is making a lot of racket, such as buzzing, when operating.

Outside compressor should be fine. +$2k- Dumpsters - I budgeted for 2 but we'll need three. +$700

Account ClosedCongratulations and welcome.Window AC units are a cheaper up-front capital cost, but are less efficient (both operationally and in their installation) and are hard on the windows themselves.If you already have forced-air heating, you can readily find solutions whereby an heat exchange core is installed directly in the plenum of your existing air-handler and connected to an outside compressor to provide either AC only or both heating and cooling (heat pump).  

I actually jumped the fence from the neighbors yard and cut the power to the compressor. 

You need a compressor for the hopper gun.

The concrete dust from drilling the holes should be blown out with an air pump (best to use an air compressor) so the epoxy has a good bond.

If you install two units, would that cost $15k for everything (2 units, compressor, vents, ducts, permit, etc)?
