When you do not have the air duct of your central heating as well as a/c proposal cleaned for a long time, it can absolutely cause some concerns.
The first as well as foremost thing is that it can eventually chop your central heating as well as a/c proposal unit.
It would cause it to work overtime as well as then eventually lead to the motor getting shot or even the fan. And when that happens most of the time, you would have to invest in a brand current as well as new central heating as well as a/c unit! However, in the meantime leading up to this, not getting your air duct cleaned can also be taxing on the air filters of your central heating as well as cooling unit. It wouldn’t matter if you had the best HEPA brand air filters or not. By not having the air duct of your central heating as well as a/c proposal unit cleaned it would make those HEPA brand air filters not last as long as they should as well as also cause terrible air quality in your home. So do yourself a favor as well as get your air duct cleaned on a common basis. Even twice a year is superb enough to keep things rolling with your central heating as well as a/c proposal unit. That is what I do as well as I have no concerns what so ever. I also get our seasonal heating as well as a/c proposal tune up as well as check ups that help too, however call your local heat as well as air conditioning contractor for pricing as well as more information.
