Thank you so much to Roger. I have a 16 year old son who thinks he knows it all. I bought him an air filter as requested on 6/21. turned out it wasn't the one he wanted. Of course the kid got mad but my husband said to take to it Roger. If Church's made mistake they would fix it. He would help us as my husband was out of town working. Church's did not make the mistake, the kid did. Well it's true!! Roger helped the kid change the filter we bought and replace the filter he wanted all in about 15 minutes. He was nice to my son and me!! If it's something we think we can fix ourselves, I'm going to Roger!!
