In 2020 we had a ductless mini split system installed in our house. The last two summers have been miserable as the units continually recycle humidity in the house instead of removing it. After complaining to the HVAC company that installed the system and getting nowhere, on a neighbor's suggestion I finally called Indoor Air Quality Medics. A technician performed a full inspection of the entire system and determined the compressor was not sized appropriately nor is it compatible with the indoor units. I spoke with the owner Dario regarding our options. All three units that were installed are oversized, thus they were short cycling. The total of the three units was also more than the compressor could handle thus the entire system was not working properly. In order to not replace the entire system we decided to replace only one unit with one of the proper size and have the jumpers cut in all three units. Cutting the jumpers means the short cycling will now be addressed and our house should not be humid when the air conditioning is running this coming summer. I had researched this option and confirmed with the manufacture that this would work. However, no HVAC company would agree to cut the jumpers until Dario said his team would do it. Jonathan was the team lead on the installation. He and the entire team were polite, respectful of my house, talked with me about everything, and went above and beyond what I expected. I will now use IAQM going forward. They fixed the mistakes of the other company, were courteous, and trustworthy. Thank goodness for honest companies. If you have had a ductless mini split system installed and experience humidity during the summer it is likely that an oversized unit was installed. You need to have the fan turned off the auto setting. In the Mitsubishi units I have this has be done manually by cutting jumpers. Dario’s team at IAQM knows how to do this. I highly recommend IAQ Medics.
