We had not cleaned our ducts in quite a few years (and I was a little embarrassed!). Joe at Dial One was very friendly and professional as my initial contact and made me feel not as embarrassed/at ease. Will was great for the booking over the phone, very polite and also professional. Aiman arrived on time for our appointment and was very polite, friendly and professional. He worked efficiently and gave us some great tips about our furnace filter. I am so happy that our ducts and dryer vent are clean! I highly recommend Dial One!
