We had a problem with our A/C few weeks ago which was caused by the drain line being clogged.
Friend told us to pour Bleach in to unclog which we did and it did help to clear it out.
Day later we had Munns come in to do a PM and he advised us never to use bleach.
The fumes from Bleach are very corrosive and can do serious harm to your system.
Recommended to only use vinegar.
