How to Prepare and Clean a Central Air Unit in Time for Summer
Nothing beats the summer heatwave like crisp, cool air conditioning. But if you’ve let your unit run summer after summer without proper cleaning, it can cost you.
Take a look at this guide to know how to clean a central air unit before the summer kicks in.
Prepping Your Unit
First things first, switch off your breaker before you work on your air conditioner. Turn off any connections to the machine, its condenser, or the thermostat.
Then, take note of how your machine is put together. If you’re going to be taking pieces of the machine apart, make sure you remember how they fit back together. Have a container handy to hold any screws or small pieces until you’re ready to reassemble things.
Getting your AC unit ready for summer will keep it cooling in a cost-effective way. It’ll also prevent unsafe air from circulating throughout your home.
How to Clean a Central Air Unit
The easiest way to clean and prep your air conditioning system is by breaking it down into sections. Follow the guidelines below and you’ll have no problem!
Fins and Filters
Your AC unit’s fins and filters will have accumulated a lot of debris and dust over the course of the year. Clean off the fins using a coarse-bristled brush or toothbrush. Wipe the filters (or the fan) down with a clean rag to remove dust and dirt.
If your filters are starting to look clogged, it may be time to replace them. Cleaning or replacing AC filters regularly will help your machine continue to run efficiently. That saves you money in the long run!
Clean the Coils and Condenser
On your outside unit, make sure to clean the coils, grilles, and check the coolant lines. You should wipe your coils and grilles clean of all debris, plant material, and other build-ups.
You can clean the outside of your coils with a soft brush or rag. The insides can be cleaned with a vacuum if needed.
As you check your coolant lines, take note of the insulation. Each line should be covered in foam insulation, which should be free from damage. Otherwise, you should replace the insulation before starting up your machine again.
Put Things Back Together
Once you’ve finished cleaning your machine, it’s time to put everything back together. Refer to the user manual or any notes you made when you disassembled. For ease, put things back together as you go.
Test Your Unit
Once you’ve reassembled everything, you’re ready to test your unit. Double-check that all the parts and pieces are in their proper place and switch your breaker back on. Turn on the power to your machine and set your thermostat to a cool setting.
As your machine gets going, listen for any unusual noises. Take note of any rumbling or leaking sounds. You want to make sure you didn’t inadvertently damage any part of your unit as you cleaned.
If all goes well, you’ll be feeling the sweet relief of AC in no time!
