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.

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.

As a new small business owner, I was working with a deadline to get our business up and running. During this COVID 19 scare, an hvac contractor I paid to finish job, refused to finish a job he was paid in full to complete. I know I know , never pay in full until the job is done. I called and spoke to Jessica. Jessica noticed I was upset and freaking out a bit. She calmed me down and had Levi out in two days to help get our cooler going. They showed up when they were supposed to and Levi was amazing. Thanks guys. I'll be using R.J. O'Neil in the future.

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.

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

Most recently we hired R.J. O’Neil to work on a remodel project for our company. The entire team was great! They were quick with visiting our location to better understand our need and getting us quotes. Once the project began their team was very professional, knowledgeable, and safe. They followed our safety requirements and got the job done quickly. On top of that, they were less expensive than other competitors. We plan on calling them on future projects and maintenance calls.
