John has a wealth of knowledge and experience on all things plumbing, heating, and air conditioning for homeowners. He helped us make the right selection of equipment and installation options for AC and furnace units as well as installing a home water filtration system.

I called to get information for a service. The person was rude and unprofessional.

John is a great guy, super up-front and honest about what you might need, and upfront and reasonable on the cost. Came within an hour of me calling him early in a Friday afternoon. Promptly fixed our heater, which was a little challenging since it’s an outdoor unit for our condo. I’ll definitely call him again if we need help.

I called John to see if he could fix my Mom's AC. The way the weather is right now, I knew it was a long shot. He was able to fit her into his schedule and fixed the issue within the hour. He was on time and reasonably priced. He is knowledgeable and great at his profession.

John did great work for me. I have had him replace my air conditioner, furnace and water heater. He recommended a tankless water heater which I did get. I am very pleased with his suggestions and work. His prices were very fair and he lived up to my expectations. I highly recommend him.

John was very responsive to my needs, we wanted to repair our air conditioner and the cost to repair out weighed the cost to install the new full Heating and Air system, with the change of refrigerant from R22 to R410a we decided to go with what he recommended. Just in case someone reads this review R22 refrigerant has been phased out and will no longer be available at a reasonable cost. So expect to pay 1200 to 1500 for any major repairs with no guarantees due to a leak.Thank you John for educating us!Thank you for the beautiful installation of the HVAC system, and the Tankless Water heater Install.John also does plumbing and is very rehearsed on all aspects of plumbing Heating and air conditioning.We will recommend you to all our friends.Services: HVAC duct & vent repair

I can't say enough nice things about John, owner of JJPlumbing. He was at my home today and did a beautiful job installing a Halo 5 whole house water filtration system. I'm so happy with the installation he did. I worried about a lot of things unnecessarily. I'm older and have experienced some incapable installers in the past which makes it difficult for the good installers. This was my first call to John so I didn't know how skillful and professional he is. John had an excellent solution for all the areas I was so concerned about. John was very patient with me and answered a lot of questions that I had. This is my first experience with a whole house water filtration system. Oceanside City water has so much Chloramines and other chemicals in it that it eats up the best quality copper pipes. Copper pipes should last 50-75 years. Oceanside Water destroyed my new copper pipes in 18 years. Pinhole leaks! The water here is also very bad for your health in the shower and to drink. After educating myself about the issues with the water here, I contacted John and did myself and my home a favor by having a Halo 5 carbon filtration system installed. I'm so happy with the installation John did. He's very organized, particular, and professional in my opinion. All I can say is John did a beautiful job and I'm very pleased. I highly recommend him and will call him in the future.

My AC was on the fritz. I had another company out 5 times and it would work for a week then conk out. I called JJ and he came out. He was honest and I felt comfortable with his recommendations. He replaced my whole heating and AC system. He was efficient and honest about the whole Job. I was so pleased that I had him service the tankless water heater at my rental unit. Thank you JJ!
