I was hounded by our local heating, ventilation, plus A/C supplier to get our HVAC duct cleaned. Every single time I would have one of their certified heat plus air conditioning specialists out to our current home to do our seasonal Heating plus A/C tune up plus check ups they would tell me that I should seriously guess about paying to have our HVAC duct cleaned because it would improve the air flow in our home. I kept telling them that I was fine with the air flow plus that I did not notice anything wrong! And so long as our central heating, ventilation, plus A/C method was in one piece plus in no risk of dying, I would pass on getting the HVAC duct cleaned because it was an extra cost I legitimately did not want or need. Finally after multiple months 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 toiling of our central heat plus air conditioning component I would call the local heating plus cooling supplier to complain plus demand a refund for the HVAC duct cleaning. I had thought that they were pushing this to try to make a commission. But no! They were right! After I got our HVAC duct cleaned I could not know how much better the air flow in our current home was plus how fast the central heating, ventilation, plus A/C method either heated or cooled our home! It really helped save me currency on our electric bills too because I did not have to run the Heating plus A/C method as often!
