You know when it is time to get your ductwork cleaned when you start seeing dust particles blowing out of the air vents every single time you turn on your central heating and air conditioning system.
This was the sign I took when I knew I had to get my ductwork cleaned last time.
And when it gets that bad you should really start thinking about having your ductwork cleaned on a regular basis every other month or so. Because if you do not, you will find yourself with one of 2 things happening. Either you will have to pay a lot of money for a hard ductwork cleaning like I did last time, also known as a deep ductwork cleaning. Or you could end up just killing your central heating and air conditioning system all together from it being so overworked that the motor blows out. If that happens it is going to cost you a small bundle just to get a replacement motor. Or even worse, it could be to where you may need to get a completely brand new and up to date central heating and air conditioning system which would of course cost thousands! You can avoid all of this when you just simply get your ductwork cleaned on a regular bi monthly basis and also be sure to get your central heating and air conditioning system tuned up and checked up every single season. Once in the winter, once in the summer, once in the fall and then again once in the spring.
