I was called to a home to perform a routine maintenance check on two air conditioning units. The first unit was a Rudd 3.5 ton unit that was installed in 2020. The second unit was a Rheem 4 ton unit that was installed in 2021. Both units were brand new and had never been used. I started by washing down the units to remove any dirt or debris that could have accumulated. I then checked the fuses and found that both units were working properly. Next, I vacuumed out the drain line and cleaned the coils on the inside and outside of the units. The coils were still in good condition and were actively working. I also checked the surge protector on both units and found that it was still in good condition. The surge protector is designed to protect the units from power surges and other electrical issues. Finally, I tested the unit's operation by turning them on and off and checking the temperature inside the house. Both units were working properly and were cooling the house effectively. Over
