Troubleshooting Common Mini Split Air Conditioner Problems Troubleshooting Common Mini Split Air Conditioner Problems
When your mini split air conditioner does not work, you should begin to troubleshoot it before you make repairs. But you may be at a loss for what to look for, so here is a quick guide to help you get started.
Step 1: Check Power Source or Battery
This is likely an obvious step to make, but it can be one of the most overlooked as well. Not only checking it could save you money, it can also help keeping your air conditioner's life longer. Check for any wires sticking out or other damage like that. If it does have damage, buy a new power supply.
As for batteries in the remote, if they are older than 6 months it is a good idea to change them. But also check the batteries and the battery area for any corrosion. If any, you will need to clean the area thoroughly before you can change them. Otherwise, that will damage your new batteries and it will still face the same problems as before.
Step 2: Check Filters
Filters should be the next thing that you check. If it is not cooling or heating the rooms, the filter is almost always the reason why. If they appear to be in decent shape and have no mold, you can leave them in there. If they appear dirty, you can vacuum them to see if it can come off. If so, you can keep vacuuming them and wait until they appear to clean and pop them back in. If neither of the above is true, you should replace them.
In general, you should replace the filters every six months, and you should vacuum them every 6 weeks. That will prolong their use, and therefore save you more money in the long run.
Step 3: Check Vents
You may want to check to see if your air vents are clean, as these can also cause you issues. Open up the vents and shine a flashlight in it. If it appears to be clogged, you will need to call a professional in to clean it for you. They will have the right equipment to perform the job and do it right the first time. You may want to have this done on a yearly basis for the best results.
Step 4: Check The Unit
The last step is to check the unit as a whole. This would be the worst issue due to the cost. Your best bet would be to hire a contractor to take a look at it for you. They will be able to find the cause and make the repairs. But if they cannot, it will need to be replaced.
