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

"This is a difficult one to write because, in the end, I think the actual work done was completed very well and professionally. We had a tankless water heater installed to replace our aging tank. The problem i have is with their business practices and lack of effective/accurate communication. A two-day job stretched to a week+ due to workers leaving early every day for one reason or another. Admittedly, one of the days was understandable due to a family emergency and I absolutely cannot begrudge somebody leaving early to attend to their child. That’s just being a good dad. The job completed on a Friday and I was repeatedly assured that an county inspector & Pure Plumbing employee would be arrive early Tuesday (Monday was Memorial Day) to close the job. Nobody ever showed up and I was told nothing. I came to learn that Pure Plumbing plays some shady games when it comes to permitting a project. They (illegally) do the work without pulling permits. Then, after it is done, they submit drawings of the completed work to get an after-the-fact permit pulled. It’s only then that they request an inspection which happens a couple weeks after the fact. They also expect full payment before the work passes inspection. I tried to contact the owner of the company (Andrew Aranda) via phone and the email his office supplied in order to discuss/resolve the issue, but never heard a reply. Unpermitted work exposes the company and the homeowner to potential fines and long delays in completion. Even though I love the work they did and would love to use them again, I would hesitate because of legally questionable methods that cast a shady layer over the operation. Are there other hidden corners being cut? Their talented roster of tradesmen/women isn’t worth doing business with because legal games are being played with the county. I plan on contacting a Clark County agent to discuss this job and warn them of potential future dishonesty."

"Amazingly well...we saw the water heater was leaking on Thursday and ordered the service and Todd came out the next day. He had a compatible water heater on the truck and installed it for us in 2 hours. I was impressed with his expertise and advice. He even took the old one away. Will use them again. Would give better than A rating if I could."

"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."

"Got a new air conditioning system, all set for summer! The install was fast and clean and the team answered all my questions!"

"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."

"Tankless water heater installed in June developed a leak and corroded. The heater was not installed with proper clearances per the install manual of the manufacturer. However, after bringing up these issues, they promptly moved the heater into a better location providing proper clearances and replaced the corroded parts."
