The furnace won't come on unless I turn on the switch on the furnace and this only keep the heat on for a few hours and the thermostat must be on 90 to stay on...10 year and the problem started when I first moved in my house but has gotten worst

Without more information to perform a proper diagnostic it is hard to say what the specific problem is and what it will take to fix it.
You need to call an HVAC technician to perform the diagnostics. You can find one here: http://www.furnacecompare.com/choosing_a_contractor.html. If you scroll down the page you can find reputable techs by state.
To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present. To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl
