1. This was my first time getting the vents cleaned. The customer service rep patiently explained the whole process to me which was very useful. Later I would call two other places for quotes and though I was getting better rates, I decided to stick with Safety King because of my phone interaction with the customer service rep. 2. I got an email with the names and faces of my cleaners the day before so when Jason and Vernon showed up it felt like I already knew them 3. Jason and Vernon were super nice to interact with and very professional 4. Since I was busy I did not supervise or inspect everything that was going on but the before and after pictures suggest improvements in the dust situation. Here’s to better breathing and fewer dust allergies! I wish Safety King and their employees success in their business.
