Need support from a HVAC person - my furnace will turn on and get up to the temperature that I've set it to. Then, it cycles off and will cycle back on again. Sometimes when it cycles back on again it can't get back up to the temperature I've set it to. So, I turn it off and on again and it works. It works MUCH better when it's a little warmer out(35-50 degrees outside temp) When it's cooler (30 and below), I'm turning it off and on again multiple times per day.
It's a York furnace, manufactured in 2009, and it's set to 68 degrees.
Please help. Thanks!!
