When you have issues with your central heating and air conditioning system they need to be attended to.
They simply will not fix themselves.
And if you do not get them attended to it could end up costing you to have to get an entire new heating and air conditioning unit. One thing that should be looked at if you are having weak air flow is your ductwork. When you have weak air flow most of the time that means that your ductwork needs to be cleaned. This can be done by a simple phone call to the heating and air conditioning company. They can send out a certified heat and air conditioning specialist to clean the ductwork of your central heat and a/c unit for a pretty decent price most of the time. However if you either never had your ductwork cleaned before or it has been a while, then you need to prepare for the fact that it may cost you a little more because they will have to do what is called a deep ductwork cleaning. And a deep ductwork cleaning will cost you normally double the cost of what it is normally. This is because it takes twice as long and is much more detailed in the work of the ductwork cleaning all together. To avoid this, it is always best to get the ductwork of your central heating and air conditioning system cleaned regularly. This would be about every 4 to 6 months. This will keep your ductwork clean and good air flow going through it.
