We have used O'Connor for over 15 years. Every time I have called, they have been nice, professional, fast, and very good at diagnosing and fixing the problem. We have called over holiday weekends, during heat waves, and when it has been freezing cold. They have always responded and had it fixed within a few hours. They talk and listen to me, where other companies would only listen to my husband. I would give them a thousand stars if I could.

The boss person who answers the phones and schedules his guys is always so kind and listens to our needs to send the right person for the job. We would highly...

Having worked in property management for several years, I’ve been fortunate to learn quite a bit about maintenance. However, one thing I did not fully realize was the importance of regularly cleaning not only your dryer vents, but also the ductwork throughout your home. During a recent cleaning at my home, the technicians from O’Connor discovered dangerously high carbon monoxide levels. This discovery truly may have saved my life. For the past several weeks, I had been feeling extremely tired and unwell. I even went to the doctor and had blood...
