"Jason was Very knowledgeable and the work was done as promised. Tankless water heater was installed. Couldn't be more happy."

"From the initial contact with the office to the final service, they were an excellent choice. They did not try to oversell; I was given three options, including replacing the current system with the same choice (the cheapest) and two additional choices providing different options at different levels of cost. Other companies that provided a quote only offered one option and looked for a decision immediately, The two service techs that came out and installed my new system were exceptional. They wore masks and gloves for my safety and explained everything that they were doing each step of the way. The system has been in for a week now and I am still having difficulty getting used to how wonderful the water feels compared to the many years of super hard water. The company was an excellent choice and will be my plumber from now on."

"Their water expert, Todd, identified the issue after several troubleshooting steps and the water softener has worked continuously for the first time ever that we've had it. Very impressed with Todd's technical knowledge."

"I hired Don to install a new hot water heater in my home and replace a faucet in my backyard. I was extremely impressed with the quality of work that he did. I will definitely be hiring him again and will be passing his name on to others who are in the need of a good, honest, and reliable plumber."

"I really appreciated the quick response. Keegan also pointed out other areas that may soon require repairs."

"I had main shut off valve replaced, new water softener (Hague), new water heater, new manobloc installed, R/O system installed by Angel & John. They worked for 8 hours diligently & professionally throughout the job. Job completed 8pm. They cleaned up everything & did an outstanding job. I had some concerns the following day & they returned to address my concerns. These guys have a great attitude & is an asset to Loyalty Plumbing & AC. Thank you so much. Highly recommended."

"I've been using Johnny On the Spot for many years now and they have come through every time for me. They replaced my Air Conditioner and my Hot Water Heater and my Heater system to be at their best all the time. Every year they come and inspect them for $39.00 and keep them working so as to not have any emergencies! Yesterday Arturo Agundez inspected my Air Conditioner and Tony Castellanos inspected my Hot Water Heater. Arturo found my Air Conditioner to have no problems but he cleaned my filter and checked all aspects of it to be working great and found some things to be concerned about. Tony found a problem with my Water Heater Anode Rod and thankfully replaced it so I would have no emergency problem with it sooner than later. Both of them showed up on time and with their expertise I knew I was in good hands! I highly recommend Johnny On the Spot for their service as you will be in good hands I promise and I will continue to use them in the future."

"The relief valve on our water heater started leaking, which caused me to call a plumber. The Will's All Pro representative did a very prompt, very complete analysis of the problem. It was clearly time to replace our old tank-type water heater. We settled on a more efficient tankless as a replacement. The installer team arrived that same day, with ALL of the parts and pieces needed for a clean and efficient installation. We also discovered very high water pressure in the house which was addressed by installing a heavy-duty PRV valve. Overall an excellent professional installation. We are very pleased."
