A while back, I got a routine visit from an HVAC technician.
I had called out the HVAC technician to fix a problem with my air conditioning unit.
It was not running very effectively and there was very little cold air coming from the vents. In addition to the air conditioning unit not functioning properly, me and my family were coughing and sneezing quite a lot as of late. The HVAC technician informed me and my husband that the HVAC vents needed some extensive cleaning. Dirt and dust build-up had caused some mechanical failures that he was able to fix. However, the main problem was the wearing down of those components by all of the dust build-up that was choking up the system and restricting airflow. I gladly paid for an extensive cleaning to fix the problem. We hoped that this would allow our air conditioning system to run as good as new, with forceful, powerful, cold air coming from the vents once more. The HVAC technician also promised that are coughing and sneezing and congestion would significantly lessen with a cleaner HVAC unit. After all the cleaning and repairs were done, I have to say that he was correct. It was so much better to breathe clean, fresh air and have cooling air conditioning once more! Since then, me and my husband have results to regularly scheduled cleanings of our HVAC unit and air ducts so that they will never get that dirty ever again! I would recommend cleaning out your climate control unit as frequently as is needed.
