I fixed the air leaks!
The HVAC duct of my central heating plus air conditioner system had some major issues.
This was something I had never dealt with before. So I had to call the local heating plus air conditioner supplier to have them send out a certified heating plus air conditioner specialist to look at the HVAC duct. As it turned out, the HVAC duct needed some redoing as it had gone weak from it being so old. This was going to cost me a few bucks but I easily did not have any choice in the matter. So I had the heating plus air conditioner specialist get his tools plus do the work that needed to be done to repair the HVAC duct. It took almost all afternoon it was that detailed. And the fact that he was by himself made it take this long as well. But when all was said plus done the HVAC duct of my central heating plus air conditioner system was repaired plus all was fine again. But the bill from the local heating plus air conditioner supplier was not pretty what so ever. But again, I had to do this plus easily had no choice in the matter if I wanted to have indoor comfort once again plus have the air flow of my central heating plus air conditioner system laboring fine again. At least though now that I had the HVAC duct of my central heating plus air conditioner system repaired I could now rest straight-forward plus not have to worry about anything else with the HVAC duct for a long time other than the HVAC duct cleaning.
