I noticed when I turned my AC on for the first time this year, the air blowing from the vents was very weak. I figured there must be some reason for this. Today, I’m going to show you how to get your HVAC unit back in shape, by cleaning it out and allowing more airflow.
Tools / items needed:
First and Foremost – Turn off all power to your HVAC unit. Turn the power off for your HVAC on your breaker box. Also, turn off any switches on the unit itself. You don’t want to get shocked.
Check your air filter and see if it can be replaced. Mine was overdue to be replaced. I suggest using the cheaper green air filters. You can usually get a 3 pack for about $2. They will allow more air flow than the pleated filters, so your unit won’t have to work as hard. This will save on energy costs. Change these filters out about ever 6 weeks.
Unscrew your cover on your unit. On my unit I had to use a socket set, however your unit may be a little different. Once you get the cover off, you should be able to see the coils/fins that the air passes through to get cooler.
The fins are usually where you will see dirt, hair, & gunk. I spray this with Simple Green (1 part Simple Green, 5 parts water). Then scrub off all the gunk with a scrub pad. I actually use a “scrub daddy”, which seems to work really well. Be careful not to bend any of the fins when you are cleaning. If you do, you can always get a fin comb to straighten them back out.
After you clean all the gunk out of there, replace the cover and put a new filter in place. Now turn everything on, and you will get better airflow coming out of your vents. I found that my house was significantly cooler. I hope you find this tip as useful as I did.
