What reviewers praise
Holiday-weekend emergency dispatch in 45 minutes when 6 other 24-hr plumbers were unavailable for 3–5 days
1 cited review
“3 Day Holiday Weekend massive pipe damage from the cold weather and these guys were at our home within 45 minutes from the call. Friday at 7:00 pm on a Holiday weekend, and we were not gouged with pricing. Actually, from the start, a LIVE person answered helped us and said the plumber would call within 30 minutes, it only took 12 minutes for him to call.”
Large property-management accounts rely on O'Connor as primary resource — competitive pricing, jobs completed within quoted cost

“Tyler was very professional and nice. He is a great plumber that took the time to explain the issue with my sump pump so that I understood how the repair was going to get solved. He did a great job! I would definitely use OConnor again for the customer service, friendly and kind professional and the reliable and fair price.”

What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
Workers documented on camera sleeping on a client's couch and going through belongings during a 2.5-week emergency repair that was quoted as 7 days — company reportedly had Google remove the original review
“This company trashed my apartment before leaving because they were doing emergency plumbing work on the apartment next to me and needed access to my apartment to fix it. They said it would take seven days instead it took 2 1/2 weeks. They locked me out of my apartment and changed the locks and told me that it was so I wouldn't mess up anything they were doing. They are on camera sleeping on my couch, looking thru my things.”
Red flag
Charged travel time and overtime without advance notification and without arriving within the stated time window — problem not fixed but still billed ~$400
Cited in 1 of the 100 reviews we analyzed.
Repeat faucet/fixture repairs resulting in leaks within a year — cited by 1 reviewer forced to use company repeatedly as landlord's preferred contractor
“Every single faucet/repair they have done, has resulted in leaks, not even a year later. The employees are rude, especially the dispatcher. She has absolutely no organization/priority and will 100% ruin your entire day.”

The evidence — in reviewers' own words
Critical
“My first review of this company was deleted by the company contacting Google but here are the photos to prove what I was saying in the first review. This company trashed my apartment before leaving because they were doing emergency plumbing work on the apartment next to me and needed access to my apartment to fix it. They said it would take seven days instead it took 2 1/2 weeks. They locked me out of my apartment …”
“If their driving is any indication of their work I would definitely steer clear. I was on the road this morning going straight on a green light and one of their vans was coming from the right on a yield to traffic. Instead of following the law, they decided to speed up to try to cut me off and almost hit me from the passenger side. Very questionable morals.”
“I have no problem with the plumbing repair. A plumber and his assistant finished the job in less than one hour. However, I was shocked to receive a bill for 2.5 hours. When I contacted the company, I was told they would charge up to 1-hr travel time and was asked "Are you sure he wasn’t there " for the 2nd hour. When I confirmed their stay time was less than 1 hour, then he insisted they stayed 1.5 hours and …”

“Alec and Spencer came to change the water heater for my apartment. I must say, the professionalism, politeness and friendly personality is a breath of fresh air in this day and age. Especially when faced with inconveniences they still maintain a pleasant and professional demeanor. (This isn't an easy apartment complex with staff and residents, so for them to stay as professional and friendly as they do, while …”
“As a large property management operator I use O'Connor as my primary resource for plumbing and guidance. They've been nothing but professional and competitive with pricing. Their Team is very knowledgeable and they always get the job done within quoted cost, on time and professionally. They're not only great at what they do but they're just overall good hearted people. I highly recommend calling O'Connor for your …”
