I think the problem must be in the fan of the thing.
I was having some air flow issues in my house due to a faulty central heating and air conditioning system unit. My money has been tight lately so I could not afford to call for a local heating and air conditioning specialist right now. However, I found an easy way to make the weak air flow actually work. That was turning on all of the ceiling fans in the house! The fans are right below the air vents in most areas, so by running the fans it helps circulate the central heating and air conditioning system a lot better as if there was nothing wrong with it. It works really well. I figure this should hold me over until I will have the money to call the local heating and air conditioning company to send out a really great and very certified heating and cooling specialist to come and fix the problem with my central heat and a/c unit. I think the problem must be in the fan of the thing. That would explain the weak air flow. I just had my ductwork cleaned not too long ago, so I know it’s not dirty ductwork that is causing the air flow to be a bit on the weak side. I will just have to wait till I can afford the local heating and air conditioning repair company next month and for now just use the ceiling fans to keep the air flow going throughout my home. It works well so far and it should stay that way.
