Arrived to perform an ac tune up. Customer said he’s been living in the home fro six years, never had a maintenance done on it. Wants to see condition, cools them down, don’t use it much because they have a swamp cooler. Cycled system on. Checked readings on the motor and are high, checked airflow pressures and like blood pressures on your body if they are high you will have health issues, same thing with the heating and ac system. Pressures are high going into mild suffocation. Pulled blower assembly out, motor is leaking oil, wheel is extremely dirty, lowering indoor air quality, but also making the motor work harder because it’s heavier to spin it, less airflow high energy costs. Heat exchanger completely discolored. Evap coil is dirty. Debris in th coils. No condensate safety switch installed. The circuit board has a burned mark on it. Has a washable filter installed and was completely clogged up. Causing that suffocation, system restriction, and high energy costs. Supply ple
