Help! Power question

My "rig" is plugged into an outlet that is all by itself on it's own breaker in the box.  All equipment is plugged into a power conditioner/surge protector (Furman).    About a month ago, new central air unit was installed into my house.    Now, whenever the air kicks on, the foobar player on pc driving rig and the DAC (Chord Qute) freezes and i have to turn both off and back on.  

What is going on!!!!!!  why is the surge protector not working! and the whole thing is on it's own circuit!

Thank You Very Much
