I contacted American Air Duct Cleaners to have the air ducts cleaned in my new house. John called me back the next day, even though he was out of town. John was very friendly and personable on the phone, while also remaining extremely professional; he asked me several detailed questions about my home, and then quoted me a price of $350. On the day of our appointment, John showed up on time, and walked through the house with me to explain everything that was going to happen. He even helped me find the best room to shut my cats in so that they weren't in the way, but also wouldn't escape out the front door while it was cracked open for the air hose. John and his assistant were very clean, and professional. I noticed very little disruption in my normal activities while they were in my home, and they cleaned up after themselves extremely well. When they were done, John's assistant asked if I wanted to see what had been removed from my furnace and air ducts. Of course, I said yes, and they showed me that their entire (very larger) canister was full. Furthermore, they explained that this was the SECOND time they had filled it. John's assistant could not remember the last time they had filled the canister twice, and John said the ducts in my house had never been cleaned (the house was built in 1948). John arrived at my house at 10:30 in the morning, and left at about 2:45 that afternoon. Even though there were more vents and returns on the second floor of my cape cod than he had anticipated, and in spite of the fact that the ducts were so dirty, John charged me exactly what he had initially quoted me over the phone. He also wrote the size of my furnace filter and built-in-humidifier filter on the invoice so that when it comes time to replace those items, I will know exactly what to purchase. John was friendly and professional throughout all my interactions with him; not only would I use his services again, but I would definitely recommend him to anyone.
