Common Problems With the Evaporator Unit

Dec 16, 2022 | Air Conditioning

Air conditioning units are made of various parts that combine to enhance the atmosphere of your home and help you feel more comfortable. If any of these parts break down, the entire system will suffer. 

At Hansen Super Techs, we enjoy educating the public on various air conditioning topics to empower them to take proper care of their units. In today’s article, we will discuss evaporator units. We will define this unit and explore the problems that can arise from this air conditioning component. 

What is an Evaporator?

Most air conditioners are two units; one for the outside and one inside. The evaporator is the indoor unit that uses hot air captured by the outdoor unit to convert it into cold air. It accomplishes this task with refrigerant fluid that runs in coils. This fluid evaporates into a cool gas and is released into the home. 

When to Call Super Techs About My Evaporator?

So how do you know when to call a technician about your evaporator? Most homeowners can avoid issues with the evaporator with a regular AC maintenance check, during which all necessary adjustments are made to allow for a smooth function of the entire air conditioner. Below are the common problems in AC units that typically arise from a poorly functioning evaporator. 

When the Evaporator Coils are Frozen

One of the top reasons to call Super Techs is when your evaporator coils accumulate ice. Most people ignore this issue but trust us; this isn’t something you want to overlook. Frozen coils are a symptom of a more significant problem, which could be one of the following: 

  • Issues with the defrosting cycle, which is in charge of preventing ice and frost from developing on the coils. 
  • Coils that are colder than the set temperature cause them to freeze and prevent the proper flow of refrigerant fluid. 
  • Low refrigerant fluid levels impede the AC’s ability to absorb the heat, which prevents the coils from freezing. 

We can see here that frozen evaporator coils can quickly grow into a big, expensive problem to fix. If the problem isn’t fixed, your AC may come to a condition beyond repair, so err on caution and give Super Techs a call. 

When the AC Isn’t Producing Cool Air

It is frustrating when the AC is running all day but isn’t producing the cool air we want. Multiple factors can cause this problem, but one of the main ones we want to highlight is malfunctioning blower motors. 

Blower motors are responsible for blowing out cool air into the home and blowing it into the evaporator coils for cooling. With prolonged use, blower motors can wear out or come off their place. A visit from a Super Techs’ repairman will help you get it back into its appropriate spot, or replaced entirely, if necessary.

When the Indoor Air Quality Decreases

If your indoor air quality decreases, you may have a problem with the evaporator unit. The evaporator absorbs air from the outside and sends it through air filters before pushing it into the room. These air filters catch all dirt, debris, and dust to ensure you breathe the highest air quality. With time, these air filters must be cleaned or replaced. 

Here are some signs that you may need to change your air filters: 

  • The AC is producing warm air
  • No air is coming from the vents
  • Your energy bills are increasing without a change in indoor temperatures
  • Visible dust floating in the air
  • Stuffiness in the room
  • Increased coughing, allergies, and asthma

The air we breathe is crucial for the health and safety of everyone. For this reason alone, taking good care of our air conditioning units is essential. Check your air filters at least once a month to ensure they are clean.
