Bunsen, I did google at first, and found prices to be quite varied. I knew the CC parents would be helpful. Just to satisfy my curiosity, I may call around to determine local costs.
I do have to say that I called the company this afternoon and the repairman came today, which I appreciate with our current heat wave here in NJ. Also, the woman who took my call suggested we change our filter first before sending out the repairman. If that was the problem, I would have saved the cost of labor. I thought that was nice of them.
