If you're not used to doing sprinklers in a cold climate area, the highs and lows of the seasons can be absolutely overwhelming, or dead as can be. The only way I could get through the times when I am getting 50-75 calls a day, sending the three of us to about 6-10 homes a day (twice that during blowouts), dealing with people upset that we are booked three weeks out, and all of the paperwork associated with running the biz, is knowing that I get extended time off in the winter.
There are times where I get up at 5:00, check and respond to emails about work, check and adjust the schedules, leave here at 7:00 to get to my first appointment, work until 5:00 or 6:00 in the field (while also managing two guys and returning a few calls while I drive), check the voice mail and return calls until 7:00/8:00, do paperwork until 10:00, fall asleep until 1:00, do more paperwork until 4:00, sleep for an hour, and do it all over again.
But then August and September I am scrambling trying to find work for us, sometimes paying the guys to work at my house just to keep them busy. It's a sh!tty cycle, but one I have become accustomed to. It'll probably put me in my grave early. It's not a consistent work pattern like the south might have.
I used to struggle in the winters many years ago, but have grown the business to a point that I don't have to work during the winter anymore. I take the time off and enjoy myself. Visit family, snowboard, hike, cook, or do nothing. Then do it all over again in the spring.
