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

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!

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.

My furnace stopped working on a very cold day. I called R.J.O'Neil and they sent a technician right away. The Technician was very knowledgeable and went above and beyond to resolve the issue. One part needed a replacement and Jessica worked with the manufacturer to get the part covered under warranty to save us the cost. They kept me informed through out the process and provided time line to get the part in and get it replaced. Will definitely call them with any HVAC related issues. Keep up the Great Service.
