R.J. O'Neil Inc.

I hired RJ O’Neil to conduct our backflow testing on our irrigation system the past two years. They are very responsive, consistent, and professional. They arrive on time and submit the required report right to the city for you. Very polite and nice to work with. I would highly recommend.

I would like to take a second to thank you and your company for all the hard work your crew has done for us at Maple Park. We have had a few of your service men here to help repair this 100 year old boiler, pumps, and radiators when they have not been easy jobs to complete. They have always come in with a positive attitude even under difficult situations. I would especially like to thank Mark my go to guy for questions and answers to the problems we have had. Again thank you for the help you have given us at the Village of Maple Park.

R. J. O'Neil Inc. is a premier plumbing contractor in the Fox Valley. I would recommend them without reservation. They did several significant and challenging projects for a vintage office building I owned in Downtown Aurora. R. J. O'Neil Inc. was a trusted vender with whom we did several challenging projects always on a Time and Material basis, because we trusted R. J. O'Neil to act fairly and in our best interests

Incredible company. Super responsive, kind, professional, timely and trustworthy! Very grateful for their help with our father's home and their quick move to assist with incredible grace.

We have been using RJ O'Neil for years. Not only for home but also for business. First off I would like to comment on their vast knowledge, reliability and complete professionalism but equally as important are the people who work for this company. They are trustworthy, respectful, personable and just flat out good people. The response time is great and are very conscientious about cleaning up when they are done. We are a fan if you can't tell....... we highly recommend them.

Our Ac wasn’t running/keeping up with the heat. Nolan, the technician came out right away checked. He cleaned the outside unit and installed a new filter.

Excellent service! Highly recommend!

Excellent communication (both via phone and email) and customer service from the first contact through completion. I was having a lot of trouble finding a company that could handle the install of my tankless water heater in a timely manner and they fit me in promptly. Quoted a rough estimate over the phone after hearing all the details and were very competitively priced. Actual job charges were in line with that estimate, which to me is commendable. Very professional on site and the work was done quickly and with care. Would definitely recommend.

I was having drainage issues in several parts of my house. The tech repair man walked through my house and patiently listened to everything. He ended up recommending that I have my bathroom rodded out however he could have sold me additional services but told me they were not necessary. He was here and done in less than 60 minutes.

Arden from R.J. O'Neil came out to our commercial building on Christmas Eve on a quasi-emergency basis to turn off our water and blow out the pipes. And then Alex came out the Sunday after Christmas to get our HVAC units up and running again. Jessica in the office helped coordinate Alex being on standby on Sunday. We truly appreciate all of their assistance and the work they did for us. I would not hesitate to recommend them - they're awesome!

Needed to have some heating work done at my place of business, after our heating unit stopped blowing warm air. It was quickly becoming an issue for my employees, and if we didn't get it fixed soon, we would have to consider canceling work. I called one company who came out, and then told me that I really just needed to replace the furnace, and gave me prices to do that. I reached out to R.J. O'Neil for a second opinion, and boy am I glad that I did. They initially said they couldn't make it till the following AM, but an hour or so later I received a call that their technician had finished a job earlier than expected and could make it out today. Great News!! The technician came out, and after troubleshooting, found out that it was a processing board that needed to be replaced. He ran back to the shop to grab one and made the switch. We had heat back up and running by the end of the day. Being a business owner, it is always nice when you can find a trustworthy company that isn't just out to make a quick buck, but to foster a business relationship. I will definitely use them again in the future for my business and personal HVAC and plumbing needs. I also will continue to refer them to others. A big thanks to the team for getting our heat working so fast.
