Scheduled our appointment with Joanne she was very polite knowledgeable and informative. The technicians arrived on time and were very careful with their setup of drop cloths tubing and duct cleaning preparation after a short time they were finished and showed us video of before and after the cleaning and also cleaned our very long dryer vent hose. We used to dust every two weeks now it is once a month and nowhere near as much dust as there was before and also our drying time with our gas dryer is 15 minutes less than previously it was a very inexpensive service that will save us money and give us cleaner air for years to come. Our thanks to Joanne Eric and his assistant.
