3 months ago, a new AC unit was installed in my home. Today I removed the cover to change my filter and discovered the current filter was not in place. It had fallen through the opening to the floor, so it is possible I have been running my AC for 3 months without a filter.
What are the consequences of this? Could this have damaged the unit?
Also, does this have anything to do with the creation of carbon monoxide?
I have been experiencing swelling, muscle soreness and fatigue for 6 weeks or so. My doctor ran tests (not for cm) and put me on a diuretic which isn't helping, but it occurred to me when I found the "no filter" scenario, that maybe this could possibly be the problem. I don't have carbon monoxide detectors now, but I will be getting some tomorrow.
