I arrived at the client's home to perform a routine maintenance check on their air conditioning unit. I ran the unit in AC mode to ensure it was functioning properly and to check for any temperature splits. I also checked for ants in the electrical system using an ohmmeter. I checked the wiring for any signs of damage or wear and tear. I checked the pressures on the outside unit to ensure it was operating at the correct level. Finally, I performed a radon test to check for any potential radon gas in the home.
