I have a Lennox 10ACB60-5P system and when I turn on the heat, I hear a cliking noise from the thermostat but no air is flowing through the ducts. I am not familiar with this system. What should I check for? is it repairable or do I need to replace the system?

Thank you

What should I check for?
Start with shutting off the service switch to the furnace, turn it back on and then try setting to heat mode again.

is it repairable or do I need to replace the system?Can't answer this question until the cause of the problem is found.
Everything is repairable depending on how much money you want to spend and if the repair parts are available.
