When you do not have the ductwork of your central heating and a/c method cleaned for a long time, it can really cause some complications.
The first and foremost thing is that it can eventually break your central heating and a/c method unit.
It would cause it to work overtime and 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 and modern central heating and a/c unit! However, in the meantime leading up to this, not getting your ductwork cleaned can also be strenuous on the air filters of your central heating and cooling unit. It wouldn’t matter if you had the best HEPA brand air filters or not. By not having the ductwork of your central heating and a/c method unit cleaned it would make those HEPA brand air filters not last as long as they should and also cause poor air quality in your home. So do yourself a favor and get your ductwork cleaned on a official basis. Even twice a year is fine enough to keep things rolling with your central heating and a/c method unit. That is what I do and I have no complications what so ever. I also get our seasonal heating and a/c method tune up and check ups that help too… Call your local heat and cooling system supplier for pricing and more information.
