Replacing air conditioner pipe insulation is not common. If installed and protected during the initial ac unit installation, the insulation last should many years.
Insulation can suffer from wear and tear as time passes. If the insulation does start to show signs of wear and tear, then repair or replacement is the best option to avoid any problems and also maintain the energy efficiency of your air conditioner.
Weather can play a huge role in the deterioration of your insulation. As the insulation is not UV rated, then a protection cover is required over all pipe insulation that is exposed to sunlight to avoid sun damage.
Poor quality insulation can certainly cause some headaches after installing your air conditioner. If the insulation is not a tight fit on the refrigerant lines then the lines can seat inside the insulation. Also, if the wall of the pipe insulation is too thin, then heat will pass through into the pipes. This will reduce the efficiency of the ac unit. If the insulation is not the correct size on the suction pipe, this could begin to sweat create water problems in the ceiling space.
The refrigerant pipe insulation must be installed the entire length of the copper pipes. This is from the service valves at the condenser end through to the evaporator (indoor) unit.
There are a few steps to replacing air conditioner pipe insulation. This should only be carried out by your air conditioning service technician.
Let's take a look at how the replacment of your air conditioner pipe insulation is done:
The existing insulation can be removed using a utility knife or some other means of cutting the insulation
The removed insulation must be disposed of correctly
The correct size and type of insulation is necessary to ensure the correct thermal qualities.
Once the new insulation is fitted, cover all the pipes that are exposed to the weather and your new pipe insulation should last for many years.
