Called out today due to odor coming from the mini split located in the daughters bedroom. I found bacterial growth and a mildew smell coming from the unit. I gave options for a one time cleaning and a permanent solution through uv sterilization. I removed the fins and cleaned the blower wheel and coil in place. Flushed drain line. Vacuumed drain from outdoor port. Measured the temperature drop across the coil. Equipment is clean and operating properly at this time. Thank you for always choosing Total Air!
