We all enjoyed that

Last month, I was talking to our husband about the air filters.  I told him about all of the information I had found on the importance of decreasing the air filters.  He told me that he took care of all of that stuff, and I didn’t need to worry about it. I never saw him buy any air filters for the oil furnace.  I didn’t even know what the air filters for the oil furnace looked like. I knew that he pulled the air filter out of the a/c quite often, however I didn’t know where they were, or what they looked like.  He just told me that a/c air filter was taken care of. I was certainly pondering what would happen if he were gone 1 year, and I had to do the air filter decreasing. He showed me where the air filters were for the AC and he walked  me through decreasing it. I asked about the oil furnace air filter and asked me if I trusted him. The two of us have been together for over twenty years, so there must be some trust there. He told me there were no air filters in our oil furnace.  I thought he was kidding. He explained to me that the two of us had a boiler. The two of us had an oil heating unit that heated the water. The only filter in the oil heater, was a fuel filter and he changed it every time he did maintenance on the oil heater.  I didn’t know if I wanted to slap him for being cagey or laugh at him.
