Your thermostat is probably not the problem, unless you have an overheating problem as well. You could have a bad heater control valve since your air conditioning is working fine.

Thanks, how much would that cost to fix and where are you located?

OK thank you

Proper diagnostics should be administered first, but if it is the heater control valve, the cost: parts, labor, coolant, tax is about $238.
