We obtained a full case of air filters from the home center, thinking we would have the new HVAC system for another year or more.
When we obtained a modern boiler plus air conditioner unit three months later, it used different air filters.
My buddy and I had the air cleaner, which also used HEPA air filters. I thought I could take the air filters back to the home center, since they were still in the wrapping plus kept in the box, but they refused to take them back. I looked at what was in the box, plus told him they sold them individually. I didn’t want cash back for the entire counter, but she could provide me discounted price back per item. She said she didn’t know where they were stored, plus if they were compromised by where they were stored. I understood what she was saying, but that didn’t mean I was happy. I didn’t know what I was going to do with these air filters when they would not fit my modern HVAC system. When the HVAC serviceman showed up to check our HVAC system, I asked him about the air filters. She said she could not provide us cash for them, but she could take them to the HVAC supplier with him. She could entirely use the air filters for other clients, plus she would not need to charge them. My wife plus I were happier with that than needing to throw them away. My buddy and I got both cases of air filters, plus made him promise not to charge anyone if she used these air filters in their HVAC system.
