Wentworth Duct Cleaning, LLC cleans ducts and dryer vents, and a recent Google customer says Gary is informed and transparent about what to expect, things to look for and benchmark pricing. A 2026 customer said the company cleaned their ducts and dryer vents, got a dead mouse out of a vent and left it smelling clean. That 2026 customer described a father and son team, and said Gary the owner told them to call anytime for help or advice.
Sometimes the answer was not to do the job. A 2025 customer said Gary and his son Kayden declined to clean the duct work in their over 200 year old home because of its fragile state, recommended an HVAC person, and that Gary showed the customer how to clean the drops in the vents themselves.
A 2023 customer said Gary and Tina showed how their equipment works and took before and after pictures of the air ducts, which seemed never to have been cleaned in the house's 40 years; that 2023 customer also said they work on mobile homes. A 2023 customer with an awful smell coming from the heating system's ductwork said Gary returned the call quickly, arrived with an associate within a day or two to inspect, and explained where the smell came from.
A 2021 customer said the wooden floor grates had been installed without enough gap to remove them, so Gary, Tina and Steve came up with a solution and rescheduled to complete the whole house; Gary also brought spray foam for a mouse issue, that 2021 customer said. A 2020 customer said a break in the duct work turned up after they began, and Gary and Tina visited three times while an HVAC company repaired it. A 2020 customer said they had hired Gary and Tina yearly for dryer duct work and every 3 years for the whole house.
A 2022 customer said it was kind of expensive, but thorough, and that one worker found money under the customer's bureau and brought it right to them.

Gary is super informed and transparent about what to expect, things to look for, benchmark pricing, and more. It's clear he cares about customers making the best decision for what they need, whether using his services or not
Just had our ducts and dryer vents cleaned by these guys! What a great experience! Super friendly and knowledgeable. Father and son team, family business. We had a dead mouse in a vent and they got it all cleaned out and smelling clean. Gary the owner told me to call anytime if I need help or advice. Feel like I made a friend for life. Give these guys a call!
This review may be a bit different than most because they didn’t actually do the job. Gary and his son Kayden were amazing. Considerate, knowledgeable and were honest as to why they didn’t feel it was in our best interest and the best interest of our home for them to do the cleaning due to the fragile state of the duct work in our over 200 year old home. They went on to recommend an HVAC person who could help trouble shoot the best way for us to heat our home. Gary showed me how to clean the drops in the vents myself because if they did it it would not be utilizing our money the best way possible. Gary wanted to do his best to help us any way possible and to give us as much information as he could, to try to save us as much money as possible.
Gary was definitely more focused on helping us and providing a service as apposed to what he stood to financially gain. This company is amazing and I would highly recommend them to everyone needing this service.
Family-owned business,courteous,clean, prompt and on time. Knowledge of what was going on, what to expect and upfront honest. No hidden fees or cost. They will go above and beyond to make sure you’re satisfied. They did an amazing job cleaning our vents and ductwork. Highly recommend and will definitely use them in the future. Jim and Susie
