Applying Freon(R022) refrigerant and A/C leak sealant

Few weeks ago, our A/C(Bryant make) went kaput.

Paid for a service call and the a/c tech did a courtsey leak test and said that the evaporator coil is leaking and gave me a quote for $1300.

I spent several days looking online for help and self-help with internet learning helped.

Here is what I did to fix it - you only need to be handy and not an HVAC certified tech to do this.

1. Got myself an EPA certification.
2. Bought a jug of R-22 online for $350(for 30 lbs) - every tech I called in town wanted to charge me $50 for a pound.
3. Purchased a manifold gauge and leak sealant from Cliplight.

Hook up your gauges to the low-side and high-side and turn on the A/C(set it to cool)

Recharge from the low-side until pressure builds up. Turn off A/C

Hook up the leak sealant. Turn on A/C and Charge the unit with leak sealant from the low-side until it's empty.

Hook up your gauges again and re-charge until you get 40 on the dial gauge.

Stop charging and continue to monitor the gauges for about 5 minutes to see if you lose pressure, if you don't then sealant has been working for so far.
