Customer Reviews

Jim Turner

My furnace died suddenly and it is winter so I needed to get service quickly. John C Flood sent Nathan to check the system, only to find that it was truly dead. Being on old heating and cooling system, any possible repairs would only have extended its life a little longer and wouldn't have been worth the cost. I was away and Nathan did a great job of explaining the problems and options. I decided on a new system after speaking with Joe, who came out the next day. He provided me with several options and I chose the one that made the most sense for my house. The following day, Scott came and installed the new furnace and A/C unit. I came home as he finished and he provided a good tips on how to manage the new system. Both my tenants and I were impressed with each person's politeness, competence and professionalism. I will continue to look to JC Flood for service down the road.

Becky Chaves

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.

Monique Carter

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.

Harry Thompson

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.
