Keep in mind if you charge $xxx for a service call that includes an hour of labor, and the problem takes five minutes* to find and fix, the customer is well within their right to want you to hang around another 55 minutes to get estimates on adding recessed lights, a spa, inquiring about other problems, and so on. For those reasons and others, my service call includes up to thirty minutes labor. Past that, I charge in fifteen minute intervals*.
*Even if it takes me two minutes to find the problem, and it sometimes takes just that, I will check other things on that circuit... sometimes there is more than one problem, or concurrent problems.
I did a 6' post light last year that didnt work. Bad photocell found, replaced, the lights flickered, and the pole shocked me... found the empty sockets full of bugs, one of the center tabs sacked out, polarity reversed, corroded connections at the wirenuts, and a skinned piece of UF inside the pole causing the shock.
*I believe the cable, phone and power companies here charge based on fifteen minute intervals too. I think it works out better for the customer as they arent paying for an entire hour that may not be used, and seeing, say, "19.50/15 min" is better than "$75/hr".
I'd think your service call price has to include some amount of labor on site, even if it's 15 minutes to tell the customer "you need a new panel" or other extensive/pricey work, and write up an estimate for them.

I do the first hour included but it doesn't matter what you call it. 85 + 90 = 175 for the first hour on the job."
Based on those numbers my service call would be $130. If my labor rate, overhead, etc were the same as yours, on calls that take an hour or less, you're making $45 more per call than I, tho you may not have as many calls or repeat business. It would be interesting to see where the breakpoint is on profitability.
