I arrived for a previous customer no heat call. I inspected the mini split system and do the system to be running in heat but barley blowing any air. I found that the homeowner cooks right under the head unit and the blower wheel is covered in grease and dust. This was preventing the blower wheel from grabbing air and blowing properly. I made this aware to the homeowner and we discussed the service cost and the cleaning cost and what a club maintenance provided. We decided to sign up on a blue club membership and to clean The evaporator coil with his club discount every 6 months to keep the grease off of the blower wheel as much as possible. I set up the cleaning curtain and pressure washed the blower wheel to free all the debris off the unit. I then cycled the system back on and we found it to have gained at least twice the air movement that it previously had. The temperature rise through the system is 35 deg with a supply air temperature of 106 deg.
