"James Stone was really good. We had a little confusion about the rebate for the original furnace they were going to install but we came to an agreement and I received half of the rebate due to me not being qualified for the full rebate. I was more than satisfied and they were very accommodating. Everything is working great. He went out of his way to make me satisfied. Thank you for giving me this company's information."

"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."

"Matt was great. Very responsive, professional and efficient. Installed a new hot water heater for us is no time. And a very fair price!"

"We had a main water line leak between two houses on our property. We received 4 estimates to replace the pipe. All recommended replacing vs trying to repair the pipe. Advanceds’ estimate wasn't the lowest, there was one lower estimate but we elected to go with them because their technicians (Jason and Taz) were so helpful and so pleasant. We felt we could trust them to do a good job as quoted and do it on time. This job was difficult as the main line lies underground beneath asphalt driveway and lawn. The asphalt and the lawn are separated by a low wooden retaining wall. The plan was to dig a trench straight through from house to house and replace the existing pipe with a new pipe. We would later have to repave the trench which would be roughly 50’ long. In addition, we would probably have to rebuild the older retaining wall. The day of the project the owner of the company, Sam, studied the situation and came up with a different plan. He and his team were able to push the pipe through the sleeve which held the broken pipe!! This prevented any need to dig!! No digging!! No breaking up the asphalt, no need to repave, no need to reseed the lawn, no need to fix the retaining wall!! Done. In a matter of hours. Can you imagine our relief? Our actual invoice was for less than half of what was originally quoted. Sam also saved us a lot of money in future repaving and possibly repairing the short retaining wall costs. Sam is not only very knowledgable but is a man with integrity. My feeling throughout this experience with Advanced is that we were all on the same team. Props as well to Isha who works in the office. Isha patiently answered all of our questions and was helpful all around. All scheduling was quick and punctual and we were kept in the loop through it all. A great team who take pride in their work! We highly recommend Advanced Professional."

"I spoke to the company owner Lou Schede on Sunday and we scheduled one of his service technicians to meet me on Monday. I informed him I would like to receive at least one hour notification prior to the person arriving for the appointment. The next day I received a text from the service technician named Kelroy. He later called me an hour in advance of arriving for the service call as Lou had committed to do. Kelroy and his helper went on to diagnose and repair the furnace issue in timely manner. I appreciate, he was making efforts to repair the furnace on this first service visit rather than replace unneeded parts or require an additional (more costly) follow up service visit."
