I am getting a water backup from the AC exchanger unit in the garage. Is this due to the drain being clogged? If so, how do you free the blockage? Thanks

Hi Jayman:

Most likely the drain piping is blocked. If there is a way to take the piping apart in the garage, do so and flush it out with your garden hose. Then, take the cover off at the cooling coil and use a wet vac to suck up any gunk that might be in there. Put it all back together and your troubles should be over. If you have to cut the pipe for access, put it back together with a union so next time it's easier to take apart. Thanks. John.
