"Got to my place later than expected because they were stuck on another job which is understandable. Did not finish my job until after 12:00 am in the morning. My job took longer than anticipated. I was given one price at the beginning and that's what we anticipated paying because I am on a budget. After the job was finished we were handed a bill that was much more than what was quoted. I was a very upset about that. I know that it took longer and they had to go back and forth to the truck to get supplies, the only thing is I wish I was informed of this during the job so I would know what to do. What if we didn't have the money? Anyway the job was done good and we are pleased with the outcome. So far our sink is working properly and good. We had a double sink installed, the faucet and we have a water omosis machine that had to get hooked up, so it did take a lot of time because piping had to be changed from a single sink to a double. I would recommend this company."

"Jimmy is a true professional with a solid work ethic. I was given a clear quote for the work and a thorough explanation of what needed to be done. I would certainly call them again for any future plumbing work. We decided to go with JRS Maintenance for a leak in our cast iron water pipes, which later turned into a bigger job. The nearby pipes were already showing signs of decay, so after an honest conversation with Jimmy, we just settled on changing that whole section leading up to the small leak with PVC (a much-needed upgrade). He arrived on time and made sure to call in advance. The old plumbing came with some concerns, which were shared in advance, but overall the job went smoothly. No doubt due to Jimmy’s skills and experience. Overall, the job didn't break the bank and ended up saving us a big headache. Glad I chose JRS."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"I had an issue with my stream boiler last Saturday. Did a google search and called multiple companies except Lighthouse (also part of Premier HVAC) picked up the phone right away and the tech Slava (unsure if I spelled his name correctly) showed up an hour after my call. He was very knowledgeable. He first did a thorough inspection on my streamer boiler (I thought mine was called furnace but he corrected me and luckily Lighthouse also repair stream boiler), then giving options (replace the water feeder and side glass or the whole stream boiler since mine was already past 30years and it may not last long). Due to budget issue, after discussed with my family, we chose for now just changed the parts. Slava has no problem with that and I got lucky that he was about to arrange time to have the work done the same day. Slava is also very patient and professional. As he learned that I am new to streamer boiler, while he was doing his work, at the same time, he was giving “a lecture “ in terms of names, functions of each parts and the concept of how the stream boiler works and how to maintain it properly. I gotta be honest that I don’t recall all the he mentioned but at least now I have a concept. In terms of the price, I can’t say that it’s cheap but you pay for the quality of service that you get. Slava literally taking his time and spent about 4 hours to repair. Highly recommend."
