The Importance Of HVAC Refrigerant

Posted on: 30 June 2018

There's never really a bad time to have your refrigerant lines checked. The refrigerant system that is connected to your HVAC is central to airflow and heat transfer. Obviously, their refrigerant helps to create hot and cold air, but it is only one part of a very complicated system. This article isn't going to try and explain exactly how refrigerant lines work in a central HVAC system, but it will give you a basic explanation. It will also explain how your refrigerant lines can be made more efficient.

The Basic Flow

The refrigerant in an HVAC system basically flows between the evaporator and condenser through a tubing system. The evaporator is inside the air handler, which is usually indoors. The condenser is in the AC unit, which is outside of the house. Cold refrigerant is created by the compressor unit inside the AC cabinet. This cold refrigerant flows into the house and to the evaporator. Air from the handler is cooled down as it blows past the cold evaporator coils.

This is basically how a split air central AC system works. Hot air is pulled out of the house and cold air is pushed in. It is a circular motion that does consume substantial energy.

How to Tell If Your System is Bad

It is often quite easy to tell if your refrigerant lines are not working properly by feeling if your air is as hot or cold as it should be. If you feel like your air is not as cold as it used to be, it probably means that your refrigerant lines are not properly calibrated, or that they simply need to be recharged. However, it could also mean that your evaporator, and/or condenser need to be serviced.

The problem with HVAC systems is that everything is so closely connected that one small problem here can lead to another problem over there. This is particularly true with refrigerant. If your evaporator is not cleaned frequently, dust can slow down evaporating process. This means that refrigerant does not smoothly flow through, so it doesn't cool down the air. As a result, you will have warmer air coming into your home, regardless of what the thermostat is set at.

Refrigerant lines are complicated and you shouldn't mess with them yourself. It is definitely best to just have an HVAC professional come to your house for AC repairs if you suspect that there something wrong with them.
