Why is my evaporator not working?

Why is my evaporator not working?

Three of the More Common Evaporator Unit Problems It could be a refrigerant leak, a clogged air filter, or grime across the coil. Blower motor malfunction: The blower fan is essential both for sending conditioned air into the ventilation system and for running warm air across the evaporator coil to remove its heat.

Why can’t I sleep in my air conditioner?

It can leave you dehydrated: sleeping with the AC on for too long can dry out your skin, mouth, throat and other parts of your body since it not only cools down the air but dehumidifies it as well.

How can you tell if your air conditioner evaporator is bad?

However, there are 4 other warning signs of a damaged AC evaporator: 1. The cool air is weak or no cold air is blowing at all. When the AC Evaporator coil or core is leaking, it will impact the effectiveness of the air conditioning system. Generally speaking, the greater the leak, the cooling capacity is reduced.

What happens when the evaporator coil is not working?

The evaporator coil contains refrigerant, which absorbs the heat being pulled from your home. If the coil doesn’t receive enough air or refrigerant levels are low, a layer of ice can develop. In some cases, the coil freezes completely. The result is less cool air coming from the ducts or, in some cases, no air at all.

Why is my central air conditioner not working?

Your central air conditioner sends refreshing, cool air through ducts to reach every room of your house. These ducts pull warm air from the house and carry it to your AC unit for treatment and cooling. If those ducts are dirty, clogged, or have a leak, air can’t travel freely.

How does the evaporator work in an air conditioner?

An air conditioning system is designed to remove heat from the air. The job of the evaporator is to harness the cold refrigerant in its liquid state. As warm air passes along the evaporator coils, it collects the heat from the air and makes it cool. The cold air is then circulated through time cabin.

What happens when the AC evaporator does not work?

The AC compressor will not activate. The compressor is intended to circulate refrigerant through the evaporator. It depends on maintaining a predetermined pressure to operate. As such, if there is a leak, there is reduced pressure within the system and the compressor will not activate.

What are the signs of a bad evaporator coil?

Occasionally, homeowners may experience malfunctions which inhibit proper performance and cause indoor comfort issues, requiring the help of a HVAC technician for air conditioning repairs. Signs of damaged evaporator coil components, include: Evaporator coils suffer from a few common issues.

What should I do if my AC evaporator is leaking?

If a leak is detected, replacement of the entire AC evaporator is the correct course of action. Some shade-tree mechanics attempt using a sealant to fix a leak, but this is always a temporary solution, and typically creates additional problems with the AC system — so we don’t recommend this type of quick-fix.

Why does my AC evaporator have a sweet smell?

You notice a strange odor when using your AC system. If your AC evaporator is leaking, a small amount of refrigerant (not coolant) will seep from the coil, core, or seals. This will produce a sweet aroma, which might get more intense when the AC is turned on.
