An essential component of your HVAC system that many people don't think about is the evaporator coils. If you neglect them, you may experience some serious problems with your air conditioner. Which is why you should know when it's time to have your evaporator coils cleaned.
Located in the indoor unit. The evaporator coils consist of multiple copper tubes that are wound together into a coil. Their job is to absorb heat from inside your home and transfer it outside. The process works by passing warm air through the evaporator coil, which causes the refrigerant inside to evaporate and absorb the heat. The cold refrigerant removes that heat and the air travels outside.
However, a dirty evaporator coil can cause a number of problems for your HVAC system. When dirt and debris accumulate on the coils, it prevents them from absorbing heat efficiently. As a result, your air conditioner will be unable to cool your home properly. Which is why it's so important to know when to have your evaporator coils cleaned.
Not to mention the average cost of an evaporator coil replacement can be quite expensive. So you'll want to avoid having to do that at all costs.
So to help you determine when it's time to clean your evaporator coils, we've outlined a few of the common signs to look out for.
Let's take a look at them.
Reduced Airflow Through Your Vents
One of the most common signs that your evaporator coils need cleaning is reduced airflow through your vents. Your HVAC system relies on the airflow to work correctly, and dirty coils can disrupt that flow.
If you notice that the airflow has weakened, it's time to have your evaporator coils inspected. You can check the airflow by placing your hand over the vents and feeling for a steady stream of air. If you notice that the air is weaker than usual, try to see if your coils are dirty.
Longer Cooling Times
When your HVAC system is operating correctly, it should cool your home quickly and efficiently, but dirty evaporator coils can slow down this process.
The buildup of dirt and debris on the coils lowers their efficiency, making cooling take more time. This is because the evaporator coil won’t absorb as much heat from the air.
If you've noticed that your HVAC system is taking longer than usual to cool your home, it's probably time to have your coils cleaned.
Water or Ice Build-up Around Your HVAC System
Another sign that your evaporator coils need cleaning is water or ice build-up around your HVAC system, more specifically around the coils themselves.
When the coils are dirty, they can't effectively remove the humidity from the air, leading to water/ice build-up around the system. Not only can this keep your system from cooling your home but this can also cause damage to your unit and needs to be addressed as soon as possible.
There is nothing worse than having an HVAC system blowing unpleasant odors throughout your home. If you notice an unpleasant smell when your HVAC system is turned on, it could be a sign that your evaporator coils need cleaning.
When dirt and debris build up on the coils, it can cause them to emit an unpleasant smell that can become stronger over time. Mildew odors are the most common type of smell you'll experiences when this happens. Mildew, fungus, and mold in your HVAC unit love to feast on the dust and build up on evaporator coils.
Higher Utility Bills
Another sign that your evaporator coils may need cleaning is higher utility bills. Dirty coils put extra strain on your system, causing it to work harder and use more energy.
This of course will cause your electric bill to also go up. If you're paying attention to your electric bill and see this spike (Knowing that something is up with your HVAC system), it's best to do a quick search for "HVAC services near me", and call up your local HVAC company.
Rising Humidity Levels In Your Home
Finally, you may notice rising humidity levels in your home. When the evaporator coils are dirty, they won't be able to absorb as much moisture from the air. This will cause more moisture and humidity in your home, which can make it feel stuffy and uncomfortable.
If you're noticing rising humidity levels, it's time to have your evaporator coils inspected and cleaned.
So remember: if you're experiencing any of the issues listed above, it's time to have your evaporator coils inspected and cleaned. Neglecting them can lead to bigger issues down the road, so don't wait too long before having them checked out.
These issues are only related to the evaporator coils themselves though. So it's also important to know other ways to tell if your HVAC unit needs attention.
Getting Your Evaporator Coils Cleaned
