Preformed system maintenance. Unit is a Reehm all electric air handler, with straight cool condensing unit. The system is running as it should at this time. Unfortunately, without an emergency shut off, the unit is out of code. There needs to be a safety float switch to bring unit up to code . I’ve provided 3 types of emergency shut off. Only recommend putting in 1 of the 3 to bring unit up to code. Also would recommend chemical clean on outdoor condensing unit. As it’s full of debris, causing the compressor and fan motor to work harder than they should and/or could possibly lead to premature failure on one of them if not both.
