When you have complications with your central HVAC plan they need to be attended to.
They simply will not repair themselves.
And if you do not get them attended to it could end up costing you to have to get an entire new HVAC unit. One thing that should be looked at if you are having weak air flow is your air duct. When you have weak air flow most of the time that means that your air duct needs to be cleaned. This can be done by a easy cellphone call to the HVAC corporation. They can send out a certified heat as well as air conditioning specialist to clean the air duct of your central heat as well as cooling system unit for a pretty good price most of the time. However if you either never had your air duct 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 air duct cleaning. And a deep air duct cleaning will cost you normally double the cost of what it is normally. This is because it takes twice as long as well as is much more detailed in the work of the air duct cleaning all together. To avoid this, it is always best to get the air duct of your central HVAC plan cleaned constantly. This would be about every 4 to 6 weeks. This will keep your air duct clean as well as great air flow going through it.
