I am a home service technician, and I recently completed a job that involved performing air conditioning maintenance. The maintenance checklist included tasks such as checking the refrigerant levels, inspecting the condenser coil, and cleaning the air filter. I also checked the thermostat settings and made adjustments as needed. One of the tasks that I performed was to check the radon levels in the home. Radon is a naturally occurring gas that can be harmful to human health if it accumulates in high levels. The radon levels in this home were within the recommended range, but I recommended installing a radon mitigation system to further reduce the levels. Overall, the maintenance job went smoothly, and the homeowner was pleased with the results. I am proud of the work that I did and look forward to completing more jobs in the future.
