HVAC service valve replacement


A technician looked at my HVAC compressor and said the service valve was "ceased and rusted" so he could not check it. Is there no way to replace this valve rather then getting a new compressor? Wants to charge 1,000 for a new compressor. Thanks Dick

Why was he called in the first place ? What was wrong to make you call?

Replace the valve or have him braize on another access port called a tap-a-line. I've used the add on port before on old units not worth the cost of replacing a rusted up king valve.

HVAC service valve replacement


Thanks Guys!

He was called originally because the unit (both inside and out) would not turn on. He diagnosed the issue as a bad circuit board in the inside unit (furnace?) He said both the thermostat was fine and the blower was fine but power was not getting beyond that circuit board. REpair bill is $500. He looked at the outside unit to check it out and that's when he said the valve was rusted and ceased and eventually it would need to be repaired at a cost of $1,000.
Having said all this, let me include that all this info has been relayed to me by my son who is at the house. I am not on site but am trying to gather as much info as I can. The compressor replacement is a guess on my part because I can't imagine replacing that valve would cost that much. Am I wrong on that assumption?

Seems steep to me, but I've never had an HVAC tech price anything out for me.

He'd have to evacaute all the refridgerant out of the system into a storage tank.

once all the freon is recovered all he'd have to do is cut out the old service valve, braze a new one in, then - pull a vaccumm on the system then re-fill with freon.
