I had a complicated issue with the water pressure in my shower that required redoing some of the plumbing in the wall. The work was a great success. I'm also on a maintenance plan with this company where they come out 3 times a year to inspect plumbing, heating, and air. There is also a discount for being on the plan. These free maintenance visits give me a lot of peace of mind and I have not ever felt they were trying to sell me on something.

Absolute rip off! I declined the recommendation thank goodness. All the tech wanted to do was sell…read morehis service. He didn't care to check warranty first.

We had him and a couple other companies come in with quotes for a new system. My wife loved Roger immediately and I was informed by her that we would be using Roger for our new install. He was very quick with securing new equipment and did a wonderful job beginning to end. One year later, time for an annual check and Roger is still answering his own phone! Roger is my HVAC guy. We love him and won't go anywhere else. Roger is the greatest!

Literally never showed up to do the work. Called & was transferred to Jordan who claimed he didn't…read moreneed to see the job first. He said it would be 2-3 days. I called more than a week later to find that Jordan hadn't even written down any of the information. Kind of hard to show up for a job when you don't bother with the little details like your customer's name, etc. Spoke with Jeremy who set a time that afternoon to look at the job for a bid. After waiting for 90 minutes I called a 3rd time and got Jordan again who thought it was hilarious that he had forgotten the first time. He then needed to see the job (after his initial bravado of "I don't need to look, we do that all the time "), he finally showed up, gave me a quote and said it would be the following week. That was two weeks ago. Never saw or heard from this company again and don't expect to. Do yourself a favor and hire a responsible professional, not a bunch of immature little boys.

He would not communicate with me unless by text. I venmoed him $380 plus $41 to replace a faucet. He would not get in touch with me and after 6 weeks his wife called left a message and wanted to know when they could come and put in the faucet. I told him that I had to pay daily for leaving the RV out and not being there with it. It did not matter to him. His workmanship and customer service is very extremely poor unless you have money to throw away and time to wast e. Then don't give your business to on-site RV repair LLC. Doug is the most unreliable person I have ever known and a big rip-off I I would give this no stars but that's not an option

I trusted this owner (Doug) with my motorhome. I have worked with him on previous occasions without…read moreincident. For this specific service, he was supposed to repair my rv's water heater. During this process, he not only did not fix the issue but also completed flooded my class A motorhome....not once but TWICE on two separate days. By this, I mean there was pouring water out of my basement compartments on both sides of my motorhome from back to front. There was even standing water in my motorhome's basement compartments. I attempted to reach him multiple times about this issue over a number of days. He wouldn't return my calls. Then, he blocked my number but accepted calls from my business phone. He finally came back to "fix it" and flooded it AGAIN! Now, I'm sure I have water damage and mold growing from my motorhome being completely flooded TWICE and the water sources in my motorhome do *NOT* work at all! This includes my sinks, toilet, shower, etc. So not only do I not have hot water...I don't have any water at all now! I live in my motorhome full-time, so this is a MAJOR issue! Yet, even though he refuses to speak to me about the flooding, he still charged me over $300 and blocked my number. In addition, he didn't show up three separate times to do the repair when he said he would be there. He no-called/no-showed all three times and wouldn't answer or return messages on any of those dates.
