"Ive been using this company for years, they’ve always been professional, honest, & dependable. recently our A/C stopped working, he was extremely dedicated to figuring out exactly what was wrong and getting it fixed so my family could have air conditioning again. He didnt just rush through the job he took the time to properly diagnose the problem & make sure everything was working the way it should. He also discovered several gas leaks in our basement that we weren’t aware of. He made sure the issue was addressed & replaced all of our gas lines, which gave us so much peace of mind knowing our home & family were safe. I also used this company for a major plumbing job that involved repairing pipes underneath our house & once again the work was handled correctly. Its hard to find a company you can truly trust, especially when it comes to plumbing, HVAC, and gas work. I used them for years I can confidently say they’re honest, knowledgeable, committed to getting the job done correctly!!"

"I hired him to do a pretty significant remodel on a duplex investment property. The building was old and had a lot of subpar work done by the previous owner that had to be fixed. He worked with my budget and stood by his work as he actually fixed a leak in the roof 2 months after the work had been completed. Anthony was a great partner as he told me exactly what to expected and helped me save money where possible. His knowledge of the investment/rental perspective helped me reach my goals with the duplex. I plan to buy again and will definitely be using Anthony and team for any work needed."

"Outstandingly! The installer from Orbit, a young man name JOHN did an outstanding job of installing, providing helpful information, and providing and extra service which required repair of a leak in the main water line coming into the house. Great job of coordinating with the American Water Company worker to manage water shut-off and turn-on. I can't thank Orbit enough for sending JOHN to install my system. Anyone receiving his services in the future is in for a treat. John deserves a "Beyond the Zone" (Military personnel will understand that terminology) pay raise he is well worth retaining as a skilled technician and one H***-of-a-nice person, a great public relations entity for ORBIT!"

"The install could not have gone better. The technician was at my home at exactly the time given. My water heater is in a carpeted hall way and the technician was careful and considerate to ensure that carpet was not damaged. The installation took about 2 hours and when done, I would never have known the technician was in the home except that I now had hot water."

"Jim was very friendly, knowledgeable and had a great attitude. They were able to fit me in at the last minute. Originally they were coming in just to do the sewage trap and I pointed out my main water line coming into my house so they were flexible enough to do both of those projects. In a short period of time. Would suggest them to anyone who needed plumbing work!"
