Question about Heating & Cooling
I have a central AC unit and when I turned it on to cool this summer I noticed that it is blowing warm air and not cooling. I called the HVAC technician who came in and told me that there is not enough Freon in the cooling system and added 4 LBS of Freon Pressure to the system. He mentioned thatere may be a minute leak, but since there was no complete Freon drainage, and that several LBS remained before he put in more, he said that this refill should be good for a few years. We ran a test and the condenser did start cooling the air.
The tech charged $85 for service visit and $90 per each LBS of Freon pressure he filled up. THe bill came out to over $500 as a result.
This is a separate unit for a tenant apartment in my house, my tenant complained to me that the central ac is not cooling again, and this is about 1 week later after the repair.
The tech mentioned that the cooling system leak test would cost $400 and there would be no guarantee that the leak would be found. Holes in the walls may need to be drilled to get to the leak.
I have not called the HVAC tech since the problem was ''repaired'' I have a dilemma since I don't know what I should do now, and if I should trust the tech, and I am sure he will try to do a test now and charge me even more money? Any good, sound technical advice? Greatly appreciated. Vlad
The man said it sould last a few years. It lasted a week? Thats not a small leak! He should come back for free for the amount of money he charged you the first time. If he doesn't I would never call him again.

If you have access to your piping system you may use a soap bubbles to test the pipe connection. the leak gas will blow the bubbles if there is leaking. But if your system is out off freon gas, you can not use this method. just try it check the connection first put the bubbles around it.
