The technician(Jul)was prompt,and took every care to keep his work area clean, with drop cloths (he even wore booties!)He walked through the house with us, counting the vents, & then gave us an exact price for the service. He worked hard all day; he didn't finish until 4 pm, & then took time to show us before & after pictures, & be sure that everything was cleaned up. We will definately recommend this company to our friends & especially our tech, Jul. He was awesome!
