I was hounded by our local heating as well as A/C supplier to get our ductwork cleaned. Every single time I would have 1 of their certified heat as well as air conditioning specialists out to our home to do our seasonal Heating as well as Air Conditioning tune up as well as check ups they would tell me that I should seriously suppose about paying to have our ductwork cleaned because it would improve the air flow in our home. I kept telling them that I was good with the air flow as well as that I did not notice anything wrong; And so long as our central heating as well as A/C proposal was in 1 piece as well as in no risk of dying, I would pass on getting the ductwork cleaned because it was an extra cost I entirely did not want or need. Finally after several weeks of this I decided to supply it a try because I was sick of hearing it. And then of course if I seen no difference in the laboring of our central heat as well as air conditioning unit I would call the local heating as well as cooling supplier to complain as well as demand a refund for the ductwork cleaning. I had thought that they were pushing this to try to make a commission. But no! They were right! After I got our ductwork cleaned I could not believe how much better the air flow in our home was as well as how fast the central heating as well as A/C proposal either heated or cooled our home! It really helped save me cash on our electric bills too because I did not have to run the Heating as well as Air Conditioning proposal as often!
