There has been a unquestionably disappointing smell in my house lately. It literally smells like a public toilet. Not just any public toilet either. A public toilet at a ball game or giant even like that. The odor is terrible. I have looked all over the house & can’t find the source of the smell. I have cleaned under the couch, under the refrigerator, & washed all of the linens. Nothing has helped. The smell remains. A unbelievable friend of mine said that I might want to look into getting my Heating & A/C system ran tests on. She said that she had a similar experience a year ago & that it turned out to be her air duct system. She had Heating & A/C workers come & scrub out the air duct & service the whole Heating & A/C system. She said they even installed a special carbon filter. The smell went away & never came back. Now she has her Heating & A/C system ran tests on at least once a year. A smelly Heating & A/C system would explain the smell in my house I suppose. It would make sense. After all, the smell is disappointing in every single room of the house. Now that I feel of it, the smell is worse when the heater is on too. I know I am going to have to hire an Heating & A/C supplier to come out & take a look. I hope they don’t charge too much though. However, at this point, I am willing to spend money just about anything to get rid of that smell. It is only getting worse & I can’t live like this.
