Hey Clint, check the thermostat first. It's about $10 at the auto parts store, and all you have to do is drain the radiator, remove the hose, change out the thermostat, and replace the hose and refill it. It's an easy fix, and generally the reason for lack of heat. Garages charge upwards of $100 to do the same. Just y two cents though, I'm not an actual mechanic...but I DID stay at a Holiday Inn Express once...
