We have a central air condition unit that is over 10 years old. Never had a problem until the other day. The unit is working but after awhile it stops blowing air. Not just cold air but any air. When we turned the unit off for awhile then turned it back on, it worked for about 2 hours then stopped blowing again. Now when we turn it back on it will blow cold air for about 5-8 minutes then it stops blowing all together. Is there anything we can try before we have to call for an expensive repair call?

Unless you have the proper tools and the knowledge to use them you will have to call for ON SITE service.

Sounds like a motor is going bad.
