Cracked Chimney Base

I noticed several cracks in the base of my chimney (for my gas furnace) - the base in concrete which is about 3ft tall - the rest of the chimney is brick.. the cracks appears to be on 2 sides of the base, and are about 1-2 ft long. I can not tell how deep they are.

My question is - do I runthe risk of the chimney collapsing? How can I repair this? who would I call to do it? Does the entire chimney need to be taken down and rebiuilt or can the base be repaired...

I live in CT, so it is cold here 0 I have notr noticeed the crack before - so could it have ben cuased by cold weather?

Appreciate the help...

Not sure how bad your cracks are, nor if there is any structural problem, but I have seen on a couple of my jobsites, they come in and pump concrete beneath the slab and raise it, providing additional footing. If the cracks are superficial, you could repoint them and see if it recurs in about a year. If so, you may be in for a footing repair.
