Looks like a client of mine is going to be flying me down to help their parents in Pacific Palisades do some upgrades this spring (current system is about 7 years old and sounds like it was a full C4 system), but don't know for sure.

I'll be scheduling a trip for most likely early April to do a walk through and will be looking to partner with a local firm as well. Post or PM if this is part of your prime service area...or if you can recommend a good reputable firm in the area.
