Maybe every 4 months sounds good.
It has been ages since I had the ductwork of my central heating and air conditioning system cleaned. It almost seems like it has been a lifetime to be honest. The air flow of my heating and air conditioning has not been going so good lately, so this was my signal that I needed ductwork cleaning. I called the heat and a/c company and scheduled one of their most certified heating and cooling specialists to clean the ductwork of my central air conditioning and heating system. The price of the ductwork cleaning was not too bad. It could have been worse. But right after I had my ductwork cleaned my heating and cooling was working better than ever before! I could not believe the huge difference in air flow coming out of the air vents of my HVAC unit. It was almost like getting a brand new and up to date central heat and a/c unit to be honest with you all. I just have to say that this whole experience was an awakening to me. In the future I am going to get my ductwork cleaned on a regular basis for sure. Maybe every 4 months sounds good. I would like to have this type of air flow going on constantly. And getting my ductwork cleaned would be the best way and possibly only way to achieve this goal. I can not believe I let my ductwork cleaning go this long. But like I said, it was a wake up call and regular ductwork cleaning is going to be all the time for me now moving forward!
