Bit certainly agreed that $250 is not enough money to install a handler, compressor, new copper lines andcharge the system.  

That didn't include the outside compressor, which was still operating normally.

Only little old nuns on Social Security, that were also taking care of 4 orphaned children, had such problems, which is why the caller really needed me to give them free next-day air shipping on a 25-pound compressor.

Contractors can't leave tools on site: compressor, table saw, nail guns, extension cords, everything needs to be packed up every day and then set up again in the morning.

Floors 1,600.00 Central A/C compressor 1,000.00 Kitch.

So it might get up to $7,000 - 10,000 dollars, but then we'll have an Air Handler or Air Compressor go out, and then it drops by $2,000 - $3,000 or $5-6,000.

The ductless system still has a compressor outside and a unit inside and the can get expensive.  

This is not foolproof, but it can be pressurized with an air compressor at low pressure, about 50-60 pounds.

Note: hydraulic pressure is instant as soon as the engine starts, air pressure build up on a truck (for the brakes) takes less than a minute.Exhaust fumes/air don’t get “sucked in” through the ac compressor unit.....stating falsehoods just diminishes your credibility on the true things.

Few things, forced are with a furnace repair/replacement, and might bundle in a compressor replacement with it as well.
