Very impressed with Jake who came out to give a project quote for replacing my furnace. He was very thorough and discussed all of my options. I'm happy to be working with him and the JCF team. I also was very pleased to have Justin come out to do the annual inspection of my HVAC unit and make recommendations for what needs to be done to either replace or repair the 18 year old system. Both were very professional, efficient, and easy to ask questions. Highly recommend JCF.
I called John C. Flood to help me to resolve a persistent sewer gas smell that was coming from the toilet in the basement of my house. The tech (John S.) who came out to my home was very knowledgeable and professional. He was able to diagnose the problem and explain the what was causing the odor issue. I am very pleased with the service that I received. I would highly recommend this company.
I was very pleased with the customer service via phone and with the representative (Francisco). I was made to feel like my issue was urgent and it was handled with care and concern. I look forward to continuing to do business with John C. Flood Inc. Phillip Russell offered excellent service and definitely showed vast knowledge of HVAC operations and merchandise. I'm looking forward to my installation. I just had my brand new furnace installed today and I am relieved to have heat and vital information regarding maintenance. Jose Velasquez was excellent. Definitely a pro in his field of work. Thanks guys for handling my situation with care.
I'm glad I called John C. Flood for a new water heater installation; Jacob was able to come out the next morning to assess and work up an estimate for me with five options, which I appreciated since my previous estimates weren't that detailed. Jacob was super professional and friendly, explaining everything and answering questions. He was also able to match the price of the previous estimates, so I decided to go ahead and he got to work in true master plumber style, finishing the whole job in a few hours. Everything looks great and now I don't have to worry about a 15+-year-old heater going out at the worst time. And yes, my anodes were way overdue for replacing as Jacob happily pointed out! I recommend calling John C. Flood for your plumbing needs, and ask for Jacob George.
Update: we had another builder-grade toilet bite the dust, and again called Flood. Harry came out promptly to rebuild it — he was efficient and professional throughout. Flood is 2 for 2 with us. Original post: Javier did a GREAT job on a very complicated, multi-day install of a central house water filter system and remediating all the goop and build-up in our hot water heater and fixtures. The piping build-out is high quality (copper) and well-constructed. He took the time to walk us through the lines, valves and how the filter canisters operate. Our water pressure is already noticeably better and fixtures are working great. Javier, thanks so much for the careful and thorough work!
