The ultimate guide to cleaning your air conditioner
Don’t wait until the heat of the summer to start thinking about your air conditioner. Spring is a great time to clean your AC and prep it for those hot months to come. Having a clean air conditioner will help it function most efficiently and keep the air in your home healthier.
Below is a guest post from Review Home Warranties. It’s a comprehensive guide that explains how to disinfect your HVAC and will answer important questions about the time it takes, the best cleaners, the frequency you should clean it and more. This guide first appeared on their website.
Keeping your air conditioner clean is vital because the system distributes air throughout your home. Once allergens, bacteria, or viruses get into your system, it can be challenging to remove them.
Due to central air conditioning systems’ complex nature, cleaning each component requires more effort than many homeowners are willing to give. However, taking the time is well worth it, because you will breathe easier and have peace of mind that your home is not making your family sick.
Now, it is more important than ever for you to keep your home clean, and that includes your air conditioner.
Should You Disinfect Your Central AC Unit Yourself?
While keeping your air conditioner clean is vital to your family’s overall health, the Environmental Protection Agency (EPA) has concerns about applying general disinfectants on heating and cooling system units and ductwork.
Cleaners marketed for use on AC parts and in air ducts must include information regarding the product’s effectiveness at destroying viruses, bacteria, mold, and other germs. These cleaners must also include specific instructions, including how much of the product to apply, the application method, and the amount of time you must leave the product for it to work.

There are products on the market for cleaning your HVAC system, but truly disinfecting your central AC without specialized equipment and training is nearly impossible. So, if you have central heating and air conditioning in your home, you would be better off hiring a professional air conditioner service company.
You can, however, perform regular maintenance, like:
Changing your air filters every 60 to 90 days
Hose the outside of your condenser coils to remove debris
Keeping your air conditioner condensate drain clean
Keeping dust and debris out of the blower and air handler
Having your HVAC system serviced semi-annually
What Supplies Do You Need To Clean Your Air Conditioning Unit?

How Often Should You Sanitize Your Air Conditioner?
Keeping your device clean helps it last longer and run more efficiently. Keeping your air conditioner filters fresh and clear will help to keep your AC cleaner.
A clean filter catches many of the dust and grime that would otherwise end up on the coils, electrical components, or fan blades.
However, it is necessary to do a deep cleaning and disinfect your air conditioner annually. If you notice your unit is not functioning as well as it once did, you might need to clean it sooner.
The cleaner your air conditioner is, the better the air quality in your home. Built-up grime, dust, dirt, pollen, dander, dead skin cells, and hair can prevent your AC unit from properly cooling your home.

Can You Disinfect A Window Unit Or Portable AC?
Window units and portable AC units are self-contained for the most part. So, disinfecting them is more straightforward.
Due to the compact design, though, the interior components can collect dust quickly. When both the evaporator and condenser coils are dirty, it is difficult for your window AC unit to cool the air efficiently.
What Are The Steps For Disinfecting Your Air Conditioner?
The steps for cleaning a window unit, portable air conditioner, or central AC are similar. However, it is best to let a licensed HVAC technician handle detailed cleaning jobs that would require you to disassemble and reassemble any parts.
If you have a portable type, performing a detailed cleaning yourself should be a fairly straightforward task using the steps below.
1. Turn Your Air Conditioner Off
Before you perform any AC maintenance, you need to turn your air conditioner off. To turn the indoor unit off, switch the thermostat to off.
Then, outside next to the condenser unit, you will find a breaker box. You need to flip that breaker to shut off power to the outside unit.
For window and portable options, power it off. Then, unplug it.
2. Remove Hoses And Covers
There is a vent hose on a portable air conditioner that has to be kept in a window. Before working on the unit, you should remove the hose from the back of the unit.
3. Remove And Clean All Of The Filters
Please remove all of the filters and clean them, removing all of the lint and dust. Then use a household cleaner or bleach to disinfect the filters.
Leave the cleaner on for around 20 to 30 minutes. Then rinse the filters and allow them to dry completely before reinstalling them.
4. Remove The Housing
Carefully remove the housing unit and use suction to remove dust, dirt, and lint, or air duster to blow it out. Pay careful attention not to damage any of the fins on the evaporator or condenser coils.
5. Clean The Coils
Spray coil bleach solution on the evaporator and condenser (let soak for at least 20 minutes). Then, rinse the coils with a hose to remove any residue and grime.
After you clean the coils, you can use a fin comb to straighten any bent fins. Then, let the coils dry completely in the sun.
6. Replace The Housing, Filters, and Covers
After you complete the cleaning process and your air conditioner is completely dry, you need to replace the housing, filters, and hoses. Once your unit is put together, you are ready to power it on.
How Do You Clean Mold Out Of A Portable AC?
One of the worst things to have in your portable AC is mold because the conditioned air blows directly out of the device and into your home. Furthermore, smaller room ACs tend to work harder to cool a space.
If the unit is unable to reduce the indoor air temperature, it will run continuously. The result is excess condensation, which fills the condensate tray quickly.
Unlike whole-home air conditioning, your portable unit does not drain. Instead, you have to empty the small drip pan manually.
The small trays frequently overflow, especially if you run it continuously. When it does, water spills inside the unit and onto the floor. The resulting moisture in your device creates a perfect place for mold to grow.
If you use window units or portable units instead of central AC, your home’s humidity level is likely higher, which only aids the growth and spread of mold spores. So, it is crucial to eliminate any mold growing in your air conditioner as early as possible.
You can’t easily see inside these machines, though, which makes it nearly impossible to identify a mildew or mold problem early. So, it is best to disinfect your portable AC or window unit at least once a year.
The steps for cleaning your AC are nearly the same as those for window units without mold. However, you will want to wear a mask and gloves, and you need to use bleach to kill the mold spores.
Are There Any Other Ways To Make Your HVAC System Cleaner?
If you have central cooling and heating in your home, you know how challenging it can be to maintain expensive home systems, especially if you are on a fixed income. There are some things you can do to reduce contaminants in your HVAC system.
Your air ducts are not visible, so most homeowners have no idea how much dirt and debris build up in them. Professional duct cleaning services find all kinds of things, and that is only what is visible.
Bacteria and mold can grow in air ducts, and over time, dust collects in them. So, it is good to have a professional business clean and disinfect them every few years.
Change Your Air Conditioner Filters
Changing or cleaning your air filters routinely is essential. The filters keep dust and harmful particles out of your air conditioning system.
When the filters get clogged, it makes your unit less efficient, causing more debris to accumulate in your indoor unit. It is also a good idea to disinfect your air filters if your unit came with reusable filters.
If you have a central HVAC, experts suggest that it is better to buy cheap filters and replace them more often.
Straighten Bent Fins
The evaporator and condenser coils in your air conditioner can get bent over time. When the fins are bent, it is easier for the build-up to accumulate, and your air conditioner might not run as well.
So, if you notice any bent fins, you should use a fin comb to straighten them carefully. You can buy one on Amazon or your local Walmart or hardware store.
Final Thoughts On Disinfecting Your Air Conditioner
You and your family depend on the cool, clean air your AC unit produces. So, it is essential to maintain your unit properly.
System maintenance includes keeping your air conditioner clean, changing the filters, addressing minor repairs, and having semi-annual tune-ups done by a reputable air conditioning service company.
A home warranty can be a great help when you need minor repairs or a total system replacement. While it will not cover HVAC cleaning, some home warranty companies offer discounts on services completed by its contractor network, which are not covered under your plan.
