Airflow Service Company is doing some work on a microwave vent hood for us in our new home. It is a new build so it is under warranty and they have been good about coming back to try to fix this. It looks like it is a problem with the microwave, not with Airflow. Their technicians have been prompt, courteous and helpful. I would tell potential customers that they are a good, reputable company with a friendly staff and workers. I would recommend Airflow Service Company.
