I had a Bryant whole house humidifier on my furnace and bought an AprilAire 600 to replace it.  THe handyman installed the humidifier but said he could not do the wiring as it is different than the Bryant wiring.  He also did not install the thermostat which needs to be done.  

I have never used gigmarket before and didn't know what to put in the date section - the date I want the work done??

Someone on nextdoor told me to use this and that Chris Peterson should do the work
