You would think that an odd and unwelcome odor would be a thing of the past with an indoor air cleaning system, but still, there was an unpleasant smell in the house.
I tried using an air freshener, but it only worsened matters.
The next day I came with the air purifier that I usually kept in the office, but it still did not help. I replaced the ac filter barely two months before the last replacement, but that too did not work. Through research on what could probably be the cause, I learned more about HVAC than I had. I tried searching for its source, but my efforts were futile. I could not look forward to going home for almost a week, which eventually resulted in drastic measures. I hired a cleaning crew and called the local service provider I knew provided quality ac service. I went through their a/c care program and I decided that it was thorough enough. Apart from a/c care, I also told the HVAC technician to add ductwork 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 air conditioning install just in case it was responsible for circulating lousy odor. I ensured that the air conditioning expert and the cleaning team worked on the same day because I was not too fond of the smell. It was less about HVAC maintenance and more about finding the root cause of my misery. When the tech and cleaning team finished, the odor had disappeared. The strange part was that none of them had come across anything that would have been the cause.
