For a long time I don't use the central heat in my house because it gives me a horrible headache. I have been having some air conditioning problems for more than a week and I have had a headache for a week.I have had work done on the ac twice in a week. If I go outside for a while the headache goes away. The ac guy is coming again tomorrow because it is not cooling..
What are the symptoms of carbon minoxide in the house?

If it's a CO problem, it would likely occur only when the heating is on because CO is a product of burning fuel. Maybe there is something in the blower/duct system that is causing the reaction.
In answer to your specific question, here's a list by Mayo Clinic staff:
"Signs and symptoms of carbon monoxide poisoning may include:
Dull headache
Weakness
Dizziness
Nausea
Vomiting
Shortness of breath
Confusion
Blurred vision
Loss of consciousness
Carbon monoxide poisoning can be especially dangerous for people who are sleeping or intoxicated. The fumes may be fatal before anyone realizes there's a problem." (Source)
