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

Perhaps a Sola constant voltage transformer would solve this issue. We used to use these for isolating test equipment. I have seen them on ebay for not much. Like under $200 for a good sized unit. 
I agree with everyone saying get an electrician over to sort it out for you. But in the meantime you could try a line conditioner like this to allow you to work around the issue:

(get the right wattage size for your needs there are multiple models)

I use one myself and while I don't have any issues I do hear the relays in the line conditioner click on and off every time my AC starts and the LC "boosts" the power.
thanks all again
re: the tripplite mentioned, many reviews says it has a rather loud "hum"

Throwing more devices on the audio rig circuit likely won’t help things.
