I recently purchased an older home with two attics that had rodent activity and poor ventilation. After researching companies, I chose One Speed Services—and they were absolutely outstanding. They removed the old insulation, corrected the ventilation, sealed entry points to prevent rodents, and installed high-quality new insulation. Every step of the process was seamless, and the difference is remarkable—my attics are now clean, energy efficient, and properly ventilated. From start to finish, the team was professional, friendly, and incredibly thorough. They arrived on time, answered all of my questions, and customer service was quick to respond whenever I needed follow-up. The entire crew went above and beyond, ensuring everything was done to the highest standard. I cannot recommend One Speed Services highly enough. If you want a job done right with exceptional care and professionalism, this is the company to call.

This is the second time we’ve used this company. They’re efficient, responsive and friendly. Dominic was our technician this time and he explained the process gave us assurances and was very professional. My only comment that I wasn’t aware of is that their process requires access to your furnace. They cut a hole and repaired it as part of their process. I just wasn’t aware ahead of time they’d be doing this. Overall, I’d recommend and use again.

A wonderful company to work with— they were able to get a technician out to us very quickly when we were dealing with an emergency HVAC issue. The technician was polite, professional, and incredibly thorough. He explained everything to me afterwards, talked through our options, and was incredibly helpful to help us manage our issue same day. 10/10 would recommend!

We were so happy with the extensive work done on our house (cleaning crawl space, laying down new barrier and installing new ductwork) that I had to write a review. They were clean, courteous, and respectful of our space. We were in the midst of dealing with other contractors who were disrespectful of our time, space and covid safety, that it was truly refreshing to have people help us on this unexpected project that we knew we could trust. That goes a long way these days.

Contacted One Speed online to have our dryer vent cleaned and promptly received a phone call. Katie was able to get squeeze us in the same day! Dominic was very friendly and explained in detail what he was going to do and quickly got the job done. Highly recommend One Speed!

100% satisfied from the free initial quote service to the last detail of cleaning up bits of insulation that naturally track in and out with the job of adding insulation into my attic. They also installed a solar attic fan to maintain healthy humidity and temperature and contracted an electrician for back energy for the fan.
My house already feels warmer and I’m looking forward to saving money all year long with better ventilation, especially in the summer!..
This is a huge improvement! Thank you One speed!
