An electrician will probably use a clamp-on amp meter to find the problem. This meter clamps around the wire, no stripping of the wire, just clamped right over the wire. The meter reads the inductive current (magnetism) flowing through (actually around) the wire. You NEED to call a pro this time. The problem could very likely be a motor going bad, a motor starter failing, or a short somewhere that is arcing and causing surges and drops in current. These problems can all cause fires. $100.00 for an electrician to find the problem would be worth it. Over the next 7 or 8 months of A/C season, you will pay for the service call in saved money. In Houston, maybe 9 months.
Tom in KY, Get it checked. Get it fixed. Get it over with. Gitter dun.
