A dryer back to one cycle was the result one Delta Clean Air Worcester customer described in an April 2025 Google review. The company offers residential and commercial air duct cleaning, dryer vent cleaning, and chimney sweeping and repair. Its website says it has been in business for 20 years and serves Worcester, Springfield, Boston and other Massachusetts communities. Customers writing in 2024 and 2025 described ventilation cleaning in their homes. In an October 2024 review, a homeowner said the technician arrived on time, opened the vents and removed dust from places the customer had not expected. Another reviewer that month described cleaning ventilation systems at two homes: technicians worked at both simultaneously after the customer approved the quote and kept the customer updated. A November 2024 customer said workers cleared dirt and old toys from vents while keeping out of the child's path. Communication received specific praise as well. A February 2025 reviewer said the workers called a few minutes before arrival and answered their many questions. An April 2025 customer described follow-up after ventilation cleaning. In December 2025, a reviewer praised Isaac for professionalism, options and advice; another that month said the workers made sure they understood everything. A July 2026 customer gives a sharply different account. In a two-star Google review, the customer described technician Mike as condescending during price discussions and hostile during the work, including telling the homeowner to go away when they took photos and objecting when they checked the work. The customer said they paid $1,600 cash. In an update, they said management had contacted them repeatedly by phone and text, but they declined further discussions and any financial refund because of how uncomfortable the encounter had made them. Google reports a five-star average from 115 ratings. BBB gives the business an A- grade.
I understand that technicians have to upsell services, and I am completely fine with standard price negotiations. What is entirely unacceptable, however, is the hostile, defensive, and deeply unprofessional attitude the technician displayed after we agreed on a price. During the pricing discussion, the technician, Mike was incredibly condescending, telling me I was being "too defensive" and actively trying to look down on me and belittle me in front of my wife. It only got worse from there. As they worked, I took a few photos of my own furniture that had been moved for the cleaning. The technician became visibly angry, snapped at me, demanded to know why I was taking photos of his equipment, and told me to "go away." Later, when I simply tried to look at and check the work being done out of genuine curiosity about how the system works, he threw a complete tantrum. He aggressively told me he was "experienced and knew what he was doing," acting incredibly defensive. His hostile reaction to a basic inspection made me feel like he was actively trying to hide poor workmanship. Negotiating a price is normal business. Treating a paying customer with disrespect, throwing tantrums, and ordering a homeowner away from inspecting their own property is completely unprofessional. I would strongly advise avoiding this company if this is how they train their staff to treat clients. UPDATE: Management has reached out multiple times via phone and text to discuss this review. However, because the technician made me feel so incredibly uncomfortable and disrespected in my own home, I have explicitly declined further discussions or any financial refunds. I paid $1,600 cash, the transaction is finished, and I am leaving this review purely as an honest warning to other homeowners about the lack of professionalism I experienced.
