Wow! It's amazing how much

can be saved, by knowing how to do things yourself!
Coincidentally just this morning ...
The heat pump had been bothering me
Thought maybe I could tell by monitoring the temp of air coming out, there was still a slow leak
And sure enough, when I got to looking around the heat pump, I found a leak
The schrader valve on the low side suction line was leaking refrigerant slowly !!!
The schrader cap covering the valve was hard to get off because of pressure
AND then I saw refrigerant bubbling out around the schrader valve
Because I have the proper tool and had watched a bunch of videos ...
I was able to replace the old bad schrader valve with a new one in less than 5minutes
And without additional refrigerant loss while doing so
Had I not replaced that valve, the system would have eventually leaked down
I would have had to call a technician again to replace the valve AND top off the system with refrigerant
It would have been well over $400
SOooo anyway, I saved myself about $300(+) this morning and call that a good morning
I have a 25lb tank of refrigerant that will be here Monday and will top the system off then
Should take less than a pound to top it off, so plenty of spare refrigerant for the future
In the picture, the old bad valve is on the right
What a new valve looks like is on the left
That old bad valve did last over 18yrs though
And I have 19 spare valves left. That should last a lifetime
That brass tool is what I used to replace the schrader valve on the refrigerant line
