As soon as I purchased my first home, I realized that it was going to be difficult to take care of all of the appliances. I was worried that some components would fail or that others would simply suffer from neglect. Unfortunately, I had no idea what to do in order to avoid these types of problems. To ward off my worries, I decided to hire a professional HVAC contractor who could help. I was able to find an incredible business in my area who really cared about their products and services. They taught me how to look for problems and how to troubleshoot a lagging system. Check out this blog for more information about protecting your HVAC system.
When your A/C unit stops working and you check out the unit to see if you can determine the problem, it might surprise you to see that the evaporator coils are frozen. This can stop your A/C from cooling your home and cause your family to become very uncomfortable. To stop that from happening, you'll have to perform the following actions to keep the machine working well.
Monitor the Coils Regularly
Like most people, you probably aren't thinking about evaporator coils every day. However, as dust and dirt build up on the coils, it becomes more difficult for the coils to work effectively and airflow inside the air conditioning unit becomes restricted until the coils freeze over.
To make sure that isn't something that happens, it's a good idea to look over the coils regularly. If you start to see buildup of dust, take one of your old toothbrushes and gently brush the evaporator coils.
Look and Listen for Signs of a Refrigerant Leak
Liquid refrigerant is one of the things your A/C unit uses to cool your air. If the coils aren't covered by dust, and the air conditioner is still not working, it could be that the refrigerant is leaking out of the unit. You should be able to tell there is a leak if you see drops coming from the unit or puddles on the ground are visible. You might also have noticed bubbling and hissing sounds if there is a leak. If that is the cause of your problem, you'll need to get in touch with a nearby HVAC professional to find where the leak is coming from and repair it.
Clear or Replace the Filter
The air filter is another thing you've got to keep an eye on if you don't want the evaporator coils to freeze. As dust is collected inside the filter, airflow is not as good as it could be. As a result of that, the coils can become very cold. For adequate airflow, you'll need to ensure that the air filter is kept clear. Empty it on a regular basis and replace it if it's starting to tear.
To avoid frozen evaporator coils, remember and use the pointers here; you should be able to prevent trouble going forward.
