I have an 05 chevy equinox. The heat works when and how it wants to, it blows fine but usually i get mildly lukewarm air. Occasionally it will be colder, occasionally warmer. I assumed it was something like the blend door as that seems to be a problem on these cars. I took it somewhere and he said he found exhaust gasses in the heat system which means its a head gasket. My question is, there is no other signs of a head gasket problem. Oil is clean, I dont leak antifreeze or overheat, no water from the exhaust, etc. Could the head gasket just cause the heat problem and nothing else? I dont have this kind of money so I really cant afford to pay him to do this and then turn around and still have to fix a heat problem. thanks

No, you don't need to see those other symptoms. In fact they are rather rare with head gasket problems unless it is very severe.

You should be seeing a loss of coolant over time though. The loss of heat would be due to air pockets so you should see the coolant slowly dropping.

That engine is very notorious for blown head gaskets.

Yes - even just some bubbles in thru heater will make it go cold despite being hot to the touch going it would be cold to the touch going out if air or vapor too much. Hot liquid only shouldn't drop temp all that much even when working but again, vapor alone would really notice which makes two strikes against head gasket problems even without leaks of oil or coolant or mixing etc.,
