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

"It was after 9:00pm on Christmas Eve so I needed the work done and I was panicked. The girl who answered the phone was very professional. The technician, Del, got back to me quickly. Del gave me an accurate estimate of how long it would be before he would be available (1 1/2 hrs) as well as an estimate of cost based on what I had told him. He arrived when he said he would. He replaced the water heater, changed the lines, put a pan and drain in, (I had been missing one), took the old one away and cleaned up the area. He then made sure that I knew what to expect with the contract and warranty since the office was closed. It all arrived via email this morning. It took only two hours and I had my hot water again. I was expecting to get fleeced because of the emergent situation late on Christmas Eve and was ready for an attempt to up-sell me on a bunch of extras. None of that happened. He was professional, prompt, and no up-sell. Just fixed what I needed for a fair price. The new water heater works much better than the old one did and I am very, very happy that they were there, available and so nice when it counted. I will definitely use them again for any other plumbing needs."

"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 had a leak in a water feed pipe for my pool fill supply that was leaking both inside and outside of an outside wall. Don quoted me a price that included replacing the old vacuum breaker and all needed fittings. Even though the work entailed more than was originally thought, Don stuck to his previously quoted price. Having been in the Trades (HVAC) for more than 40 years I can attest to the quality and attention of Dons work. Dons work was also at a very reasonable price! In this day and age it is rare to find a plumber of Dons caliber!"

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

"Our water heater quit. Vegas built was very nice and came out the next day. The work was well done and is working perfectly."

"Alex Gray, who is a dependable and skilled plumber, installed a new water shut off valve in my garage. He has worked at my home several times in the past, and I can always trust and expect a quality and complete job done before he leaves my property. Alex, who is also very kind, realized that I was not well that day and offered his assistance to any other needs that I may have. Daniel, did some maintenance on my hot water tank and also discovered the malfunction on my water shut off valve. He is also a quality professional plumber with an attention to detail who does the job right!"

"Johnny on the Spot is an awesome company! I scheduled a consultation online and someone called me immediately. James Cox, the technician who came out, quoted us an awesome price for 2 new 16 SEER units. He even gave us a good 0% financing rate for 2 years. We got 5 quotes and I have to say that this company gave us the best dollar for dollar deal for the units and the service maintenance / warranty agreement. Our new units are now installed and it all happened a week after we signed the contract! Our installers Andrew Susterka and Hector Samayoa were also very professional and great! If you need a new system or service your current system, I HIGHLY RECOMMEND this company!"
