Maybe the least people are there who can imagine their summertime without having an air conditioner at home! Of course, you may not be an exceptional one! And to keep it running well, replacing HVAC evaporator coils is necessary after a certain time.
Evaporator coils are one of the essential parts of a heating and cooling system. This component helps the AC or water heater to absorb the heat and perform at low pressure!
But you often miss some warnings saying that your HVAC coil needs replacement. In today’s blog, you can ideate some of those!

When is the right time to replace the HVAC evaporator coils?

As mentioned, the evaporator coils take all the heat from the indoor air and leave the space cool. However, the cooling coils can turn up with different problems over time that can directly impact the performance of your HVAC system!

It may be a sign of problematic HVAC coils that requires an immediate replacement! Or else you may end up damaging the air conditioner in the long run!

Poor performance!
You may have noticed that your HVAC system is not offering the same cooling as before. Well, most people consider it a reason for outside humidity, but that’s not at all!
The role of evaporator coils is to cool the indoor air. But when you don’t find that doing so or blowing hot air, it’s time to replace the coils. These signs indicate that the cooling coils of your AC may get damaged over time or in any other way. Hence, it fails to absorb the heat that makes the HVAC system provide warm air!


Needless to say, the reasons are countless here while talking about corroding evaporator coils! And the most common one is room-freshener sprays! When you shower or sprinkle the spray, the chemical comes close to the cooling coils by getting mixed with condensed air. And it results in corrosion on the coils that cause small leaks on those!
Now, how will you ideate that? Simple! Just take a glance at the drain pan or the evaporator surface for that where you may find oily deposits! Once you realize that the HVAC evaporator coils start corroding, you better replace them!

Tiny leaks on cooling coils
It’s quite common to see dripping condensed water from the air conditioner. In fact, when that is small in quantity, there’s nothing to get concerned over! But if you find the amount increasing, you need to start worrying about that because it may be the water leakage in the evaporator coils. Leaving the problem as it is can lead your HVAC system to severe damage. Instead, replace the evaporator coils ASAP!

Finding dirt and deposits
Do you know that you should get the HVAC coils and system cleaned at least once a year? Maybe NO! And it causes piled up of dirt and debris on the evaporator coil over time. The deposits prevent the coil from absorbing the indoor heat directly or quickly that can affect the performance of the AC! When the dirt lodges on the coils for all time, it indicates that those need an urgent replacement. Otherwise, the coils can get corroded!

Build up of frost
This one is another concerning fact related to cooling and heater coils that you can’t avoid! Developing frost on the coils can show up with annoying results like turning on and off AC frequently. It may cause more energy consumption and long utility bills than you expect! On the other hand, the HVAC coils fail to cool the surrounding indoor air. If you have an older AC unit, go for replacement coils instead of spending dollars to repair those! Anyway, the latter option is advisable for a new air conditioner.

We hope our advice may help you ideate the warnings of HVAC evaporator coils replacement next time as early as possible! For more blogs, stay connected!
