Most HVAC repairs need to be done by licensed professionals. Certain components are delicate and involve complicated gas and electrical systems, so you don't want to mess with them on your own. But, there are quite a few simple things that you can do yourself, even if you have no experience working on HVAC systems. This article focuses on a two simple ways to make your heat and AC airflow more powerful.
Change the Air Filter
When it comes to the airflow of your heater, the filter is always a good place to start. When a filter gets dirty, it slows down the airflow from the furnace to the ducts. Of course, it also reduces the filtering so dirtier air, chock full of dust and allergens, is now being circulated into your home. So, you want to change your filter as recommended. Most filters will say that they should be replaced every 6 months. It is a good idea to change your filter once at the end of winter, when you are done using your heater on a daily basis, and once at the end of summer, when you are done with the AC.
Filters are cheap, found at any home improvement or super store, and available in bulk. If you buy a 6 pack, for instance, you won't need to shop for filters for at least 3 years.
Clean the Air Blower
The air blower is the mechanism that forces the air into your ducts. It is worth noting that the blower also circulates air when the AC is running. So, it will get dirty year round, not just when you are running the heater. Most furnaces have the blower located in a separate compartment within the main cabinet, with its own designated door. The blower is the largest and easiest to find component in a furnace. It is also very easy to clean.
First, make sure that the power to your furnace is shut off before you try to clean the blower. Then, you can easily clean it out using a vacuum and a couple of wet rags. The job is usually easy, unless there is moisture within the system. This will cause the dust and dirt to cake up and become much harder to get off. Just use a wet rag with some mild household cleaner to help break down this difficult build up.
These two simple jobs can be done in less than an hour. But, even such simple task could improve your AC airflow.
