I was called to a home to install an air scrubber. The air scrubber is a device that cleans the air of pollutants and allergens. It is installed in the ductwork of a home and helps to improve indoor air quality. When I arrived at the home, I began by removing the old air filter and installing the new air scrubber. I then connected the air scrubber to the ductwork and tested it to ensure that it was working properly. After the air scrubber was installed, I cleaned up the work area and made sure that the new filter was working correctly. I also provided the homeowner with instructions on how to use and maintain the air scrubber. Overall, the job went smoothly and the homeowner was very pleased with the results.
