  • Isolate the power from the evaporator unit
  • Disconnect any wiring and sensors
  • Remove the refrigerant from the whole system.
  • Disconnect the pipes from the coil
  • Remove the fixings that hold the old coil in place

Tips to Keep Your Air Conditioners in Good Condition

It makes sense to do all you can to keep your AC in top shape. Here are some tips for doing just that:

Get an Annual Tune-up

One of the best things you can do for your air conditioner is to get it serviced by a professional at least once a year or more often depending on the location. It can help prevent any ducted air conditioner problems from arising. The technician should check the coils, pressure, and other parts to make sure everything is running smoothly. Also, that there are no underlying issues that could lead to costly repairs in the future.

For example, the AC evaporator coil could become clogged, making it difficult for the system to cool your home.

Keep the Area Around Your Unit Clean

Another way to keep your air conditioner in good working order is to ensure the area around your condensing unit is clean and free from debris. Leaves, twigs, dirt, and other items can block airflow and cause the system to work harder than it needs to. This can wear down parts like the evaporator coil more quickly. Cleaning the filters regularly can also keep the system running and reduce the chances of an evaporator coil needing to be replaced.

Change Your Air Filter 

Your air conditioner's filter traps dust, dirt, and other airborne particles from circulating through your home. It's important to change this filter, as a dirty filter can cause your unit to work harder than necessary and may even lead to system failure. Most filters should be cleaned every three months or so. This will help reduce the strain on your system and can prevent costly repairs down the road.

Keep Your Vents Open

In order for your air conditioner to work properly, it is important that all vents in your home are kept open. If vents are blocked, it can cause your unit to overwork itself and may even lead to system failure. In addition, it can cause expensive repairs, including the need to replace the evaporator coil. For example, it must be replaced if the evaporator coil becomes clogged due to restricted airflow.

Final Thoughts

It is important to do what you can to keep your AC in top condition. Regular maintenance and cleaning, changing the filter, all go a long way in keeping your system running efficiently and preventing costly repairs in the future. It can help extend the life of your air conditioner and save you money in the long run. So consider taking these steps to ensure that your evaporator coil doesn't need replacing anytime soon.
