One thing I wanted to voice here is that you should get the ductwork of your central heating and air conditioning system cleaned at least twice a year. Not many people even think to get the ductwork of their central heating and air conditioning system cleaned. As a matter of fact, did you know that 80% of Americans do not even bother to get their ductwork cleaned? That is true. This leads to all kinds of issues in the end. Not including just bad air quality. But also it can lead to your central heating and air conditioning system breaking down completely to the point where you need to go out and invest in a brand new one. All it takes is a few hundred bucks, a simple phone call to your local heating and air conditioning company, and then they will schedule a time for them to send out a certified heat and a/c specialist to your home to clean that ductwork of your central heating and air conditioning unit. After I had an experience of having to shell out thousands for a brand new and very up to date central heating and air conditioning system unit last year due to never having my ductwork cleaned, this was what changed my view moving forward. Keeping up with the cleaning of your ductwork is just as important as getting your seasonal heating and air conditioning system tune up and check up. It all falls hand in hand together to ensure that your central heating and air conditioning system has the longest possible life!
