You would feel that an odd and unwelcome smell would be a thing of the past with an indoor air cleaning system, however still, there was an unpleasant smell in the house.
I tried using an air freshener, however it only worsened matters.
The next afternoon I came with the air cleaner that I usually kept in the office, however it still did not help. I updated the air conditioning system filter barely two months before the last updatement, however that too did not work. Through research on what could particularly be the cause, I learned more about Heating and Air Conditioning than I had. I tried searching for its source, however my efforts were futile. I could not look forward to going home for almost a week, which eventually resulted in severe measures. I hired a cleaning crew and called the local service provider I knew gave quality air conditioning system service. I went through their a/c care program and I decided that it was thorough enough, and apart from a/c care, I also told the Heating and Air Conditioning supplier to add HVAC duct cleaning to the list of services I needed. I had to restore high indoor air quality by all means. In a desperate attempt to find a solution, I switched off the a/c install just in case it was responsible for circulating lousy smell. I ensured that the a/c expert and the cleaning team diagnosed the same afternoon because I was not too fond of the smell. It was less about Heating and Air Conditioning service and more about finding the root cause of my misery. When the tech and cleaning team finished, the smell had disappeared. The unusual part was that none of them had come across anything that would have been the cause.
