Why is my high pressure line cold?
Most likely problem is a clogged drier. If one is not used on your system the next best guess is a clogged expansion valve. I would make sure they install a new drier during the repair.
Why is my liquid line freezing?
The main reason why your AC lines are freezing is because your evaporator coils are getting too cold. The evaporator coil is filled with refrigerant which cools the air in your HVAC system. When things are working properly the evaporator absorbs the heat from your air and provides a cooling effect.
Which is the low side of the AC line?
The low side, or suction line, will be the line connected to the compressor from the top or higher position. It will be cold to the touch and may be wrapped with insulation. This is where freon enters the compressor as a gas. Step 3. The high side, or discharge line, will be the line connected to the compressor from the bottom or lower position.
What makes the high and low sides of an AC compressor?
The compressor accomplishes this task by creating high and low pressure areas with the use of a moving piston in a sealed chamber. The high and low sides on a home A/C compressor are also known as its discharge and suction lines.
How can I check the low side of my AC?
If you want to easily check the pressure readings of your AC system, a simple way to do it is by using a pressure gauge, which you can buy for a cheap price at your local shop or from online stores like Amazon. Just follow the user instructions of the pressure gauge to read your AC’s high side and low side pressure.
Is it normal for liquid line to be cold next to the air handler?
Is it normal for the liquid line to be cold next to the air handler. The liquid line gets less colder as you go outside. I decided to clean the drain pipe and notice that the liquid line was sweating by the handler and the attic.
