We had our entire home’s duct and also dryer duct cleaned in early April 2023 by Safety King. This is the 3rd time we use their service. Price was reasonable. They even honored a really old coupon we had back in 2020. My wife was coughing for a while before the service – and she never did cough that long before. Afterwards – relief! (We were overdue ~1 year on the service, so this shows the importance of doing this every ~3 to 4 years).

We’ll use them again next time, unless something changes.
