Arnold did an outstanding job of servicing my air conditioner and explaining what needed to be serviced and why. He also explained the way the membership program works. He was very pleasant and I would give him a five star rating.

They changed my hot water tank in 2 hours , excellent service . 10/10

The services I request. AC tune up, REJUVENATION, as the company advertised in tv, not even sure if it was done.The technician came down off my rooftop, showed me some pictures of his recommendation but never said what he did for the tuneup, stated he was going to email me a copy, he didn’t. The worst part is an invoice was emailed to me u set a totally different name. Called and emailed company to correct it but I’m being ignored.

Sean did a first rate installation! He was awesome! So personable, knowledgeable, professional and friendly. Love the new bronze faucet and matching filtered water spout.

We had repeatedly clogging toilet. They rrived on time and got the job done by running a snake 🐍 down the line.

Carl came on time straight forward and honest. Thank you to Michelle also, excellent service provided by both.

Service tech DeAndrew provided excellent service, I definitely recommend this company.

I've lived in Las Vegas since '02, and of course have had a lot of service calls for Air Conditioning units at a lot of different residences. By far, Number One is the best. Both of the girls at the office I spoke to, and the tech (Donovan) are the most organized, professional, efficient, honest, punctual, cordial, etc.etc., crew I have ever dealt with.

We had a complicated service situation, since we were dealing with a home warranty company and a house we just moved into this April that was built in 1993. At first, I thought to call another HVAC company that we used at another home, to just get an inspection, and do any necessary preventative maintenance. The home inspector of course didn't do any of this thoroughly, so it seemed like a good idea. Well, that first company and the tech ended up basically fixing something that wasn't broken.

Their tech had mentioned that the fan motor MIGHT need replacement soon, and the bearings were most likely worn. Coincidentally, the unit started making noise almost immediately after the first visit. It was operating fine before. When we called the company again because of the noises it was now making, the same guy came back with an attitude, made some adjustments and the sound was gone. But only again for a day or two. It was really bad at this point, and even FAILED just last Sunday. At this point, we called our warranty company to have them create a work order, and the first service company never even got back to us. We left the house that afternoon, since it was almost 90 degrees inside at that point. When we returned several hours later and turned it on it was working again, so we thought maybe it was a fluke and overloaded, etc.

The unit worked for a couple days, but was making noise even worse now. When we called the warranty company again on Tuesday, within 30 minutes a different HVAC company (Number One) responded immediately, and the tech Donovan came out within 30 minutes. Of course, as he was en route, the A/C unit magically stopped making noise. He ran a thorough inspection and test of the whole system, checking amperage levels and variances, the physical unit and clearances, compressor, capacitor, fan, you name it. There was nothing more he could do at the time, it was working properly.

Our hands were tied. The warranty company would not allow the replacement of any parts since the time Donovan was there, nothing was at failure. We all pretty much knew the fan motor was on it's last leg, but it didn't matter. We paid the deductible, and had a 30 day time frame that if any issues arose again with it, he would come out without us having to again pay a deductible.

Again this being Tuesday, everything ran well for a few days. Up until around noon yesterday. This time, we noticed it was getting hotter and hotter, and outside the unit's fan was BARELY moving. It was toast for sure. We called Number One, with excellent response and phone service again. We we're afraid that it would do the same thing, and magically start working again. When Donovan called me, He told me to turn the unit off (since I said we were leaving it running, in effort to prove that it was in fact failing) as to not damage the compressor. He said he got a pre-authorization from the warranty company to replace the fan motor, and not too worry. Prior to talking to him I thought a little video insurance would be a good idea, so I took a two-shot video of the thermostat, noted the time and dysfunction, as well as the sound the unit outside was making and how the fan was barely operating at all.

Surely enough, he again arrived within 30 minutes as he said he would, and replaced the fan motor. The fact that he got the pre-auth, and saved the hassle of having to prove anything to the lovely home warranty company in that short period of time is nothing short of outstanding. Now, the unit runs great, makes no noise, and our house isn't a sauna. Thanks Number One! Look no further folks, the team at Number One really is the best.

Don't have a clue what you're talking about...guit bothering me !!!

We are very happy with the professional quality and service

Called this person for questions about a used hot water tank. He states he could fix ours for 210, 4 year warranty, parts and labor included. Sounded too good to be true to begin with, but we hwent ahead and scheduled an appointment for the following day (we had plans we could not cancel that night). Our appointment was at 11, but he texted saying he was busy and couldn’t make it till like 1. We said ok, then noticed our breaker had been tripped for tank. So we text him this and be stated that ok we will cancel. Then he text again saying it could cause a fire so we were like ok maybe he should come out. We tried to contact him back but he started being super rude. So I’d think twice about going through this “company”. Not too professional at all!
