We have a tune up on the heat and air every six months. The company charges for one filter, of lesser quality, that we pay for the four Merv 8 pleated air filters. One return is an odd size ( I'm sure that is because we have to use the company filters ) and Filter Buy made the special size for our use.
I DID NOT PLACE AN ORDER FOR MORE FILTERS. I HAVE TWO BOXES OF THE FILTERS NOW. WHY ARE YOU SENDING THEM TO ME WHEN I DO NOT ASK FOR THEM? IT IS TOO SOON AND TOO QUICK. STOP IT PLEASE AND STOP IT NOW. I WILL ORER WHEN I NEED THEM. IT IS NOT FOR YOU TO DECIDE.
