Welcome DJK, I'm going through the same thing. The temps are really affecting the business. One thing that will help is start prospecting a door here and a door there. Make sure you are dressed well and have a clean vehicle and the inside of your vehicle is clean too. Doesn't have to be new yet it needs to look the best it can.
I find I have to give the customers a discount on something to get them motivated. If they have gutters which look fairly easy to clean, Offer a free gutter cleaning with a whole house wash. Or offer a free "front stoop" or front walkway cleaning with a whole house wash...
How about a name????
