I used this company on a reference. Renee came to my house. He was very professional. He explained everything to me and finished the work in good time. I was given a military discount which I appreciated very much. I am retired and on a pension so it really helped. Mercy on the phone was also excellent. They also came out same day. I highly recommend them from your electric needs. read more

Trash company. Doesn't do the job right and the employees don't seem to know what they're doing.

I was pleasantly surprised with this company. On an older home I owned in the past I made use of a home warranty (AHS) twice and had concluded that the contractors they hired to do the work were sub-par, spent 5 minutes diagnosing a problem, and then charged $80-90 dollar consulting fee to tell you it wasn't covered under home warranty. So my starting place was being very skeptical indeed! I moved into a home a month ago and came to realize one of the lights in the bedroom wasn't working. After some of my own diagnosis I discovered that the fixture was not connected. Despite my best judgment I decided to give the new home warranty program I was under in this house (HWA) a shot. Xavier Garza and Brandon from Sierra Electrical Services (aka Mr. Sparky), arrived and within about 30 minutes concluded that the builder had made an error and had missed connecting the light fixture and it had gone on unresolved. I had a frank discussion with Xavier around what my chances were around having the warranty cover it, and he said the chances were poor as it was original builder error. Needless to say I was disappointed, however he came back to me a few minutes later and said he was given a $500 allowance to cover problems on the spot that would be covered under warranty, and using some "creativity" in describing the problem, would do so. I was very pleased with this outcome, and I felt Xavier was advocating for my success as a customer. The following week, Brandon and Xavier came back and did the job, which took about 2 hours. I was very happy with the politeness and professionalism demonstrated, and my light fixture works great now! The only negative I would say, is that there was a lot of confusion around scheduling - tardiness (i.e. arriving outside the specified window without communication of lateness) and scheduling in the afternoon when the job should have been scheduled in the morning due to the Texas heat and needing access into the attic. Yolanda, the scheduler, needs a more organized process to managing site visits, and also work on her level of politeness and professionalism. However, this should not overshadow the overall great customer experience I had! read more

I had an electrical issue in my living room and AHS dispatched an electrician from this company. Aftter about 30 minutes investigating the issue diagnostic was that a new line would be required to get some outlets to work and he gave me a $320 estimate. I was suspicious of the diagnostic and asked for my house inspector for a second opinion. He was able to find a slightly dislodged wire that was breaking the circuit in about 10 minutes. Problem fixed! I've called Sierra's customer service, explained the issue and asked them for a refund of my $75 copy for such poorly done service. They said they wouldn't refund me no matter if the diagnostic was wrong or not. read more

On two occasions we have had electrical issues in our home. Both times our warranty company sent out Sierra. Both times the service was great. The first occasion our wired smoke alarms were malfunctioning, as well as our upstairs furnace. The tech discovered that for some odd reason our smoke alarms and furnace were wired to the same circuit. They were able to fix the problem and got us approved for new smoke detectors from our warranty company which they came back a day later and installed. The second occasions our power went out. The tech showed me our breaker box, and that the main breaker and several others has completely burned out. With no power, a fridge full of food going to spoil, and no AC in the middle of May with an 18 month old child in the house, the tech had his scheduler clear his day so he could take the time needed to replace and rewire the breaker panel so we did not have to go another day without power. He even had his boss, the master electrician, come out to assist him. My wife and I are very happy with our two experiences with Sierra. I don't recall the name of the tech that came out both times, but he was super friendly and knowledgeable. read more

I had a good experience with Sierra's tech Gerzain Mendoza. Friendly, knowledgeable, courteous, etc. I'd be happy to have Gerzain out again if we have any electrical issues in the future. Sierra came to me through my AHS home warranty and I also hired them for a 2nd electrical job that wasn't covered by the warranty. read more

They are also known as Mr. Sparky.. I called them and told them my problem.. I was told they have trucks all over town including south Austin.. He was supposed to be here @ 4pm.. He calls me at 4 pm and he is at 183 and Balcones.. A good hour drive in the traffic..He said he could give me a price over the phone before I driver down south.. He said I can tell you it will cost $688.. for the breaker and labor.. No hourly fee, just $688.. I at the point felt I was fixing to be ripped off.. I called another guy and he was there in 30 minutes.. It took him exactly 8 minutes to replace the breaker.. The breaker was $7..He only wanted $50 !!! I tipped him another $20.. Saved $618..!! Use them at your own risk.. read more

Just wanted to praise Daniel from Sierra Electrical Services for his prompt arrival and quick assessment of the problem with a dimmer switch that would become very hot when turned on. He ultimately replaced the switch and corrected the problem. He was very professional and friendly. I have a lot of confidence in Daniel and Sierra Electrical - will be the company I call for electrical help in the future. read more

My home warranty company sent Sierra Electric to come figure out why my kitchen light wouldn't turn on. Mark Garza was the electrician that came out and he was very courteous and figured out it was the ballast that had gone out. It wasn't covered by my warranty company and I paid Mark to have it replaced with a new one. My appointment was for 1 PM and Mark was able to come earlier and had it fixed within the hour. Thanks Mark, I look forward to using your services again in the future. read more

Thanks Mark for figuring out how to get my treadmill to run without throwing out every braker in the house. Awesome job and quick service. He was on time and very professional. read more

Sierra Electric Services DBA Mr. Sparky is the best of the best. They were sent by my home warranty company and to date have only been able to do bandaid my problems. This time they made it clear the bandaid would no longer work it would require new service or they would be putting my home at risk of fire. They accomplished the task in good time and went out of their way to make my family comfortable in this record heat by hooking a generator up to my home while the power was off. Great job guys. Thank you!!! read more

The Issue: we occasionally have problems with humming coming through some electrical equipment in the living room when we plug in other things in the bedroom. This happened again when we plugged in new satellite boxes. This indicates that there is an ungrounded wire somewhere in our electrical system. I called American Home Shield, and they assigned this excuse for an electrical company to us. The assignment? Check the electrical system. "The Experience:" The initial appointment scheduling itself was a bit odd. I was informed of the time and date they would arrive. When I said that wouldn't work, the scheduler seemed annoyed, as if I were inconveniencing them. Then guy from Sierra -- I don't want to insult actual electricians by referring to him as one -- showed up and claimed that Direct TV caused the problem (they don't do any wiring or anything that would affect the wiring) and that the policy didn't cover stereos (no, we weren't trying to do an end around to get AHS to fix speakers. My husband wouldn't allow anyone he hadn't known for decades near his stereo system). Since we had experienced humming and power surges in other parts of the house and since we plug the satellite receiver into the wall just like we plug every other electrical appliance into the wall, it was clear the guy from Sierra couldn't understand what we were saying or didn't know what to do or didn't care or D, all of the above. When asked to run a diagnostic to at least check for a problem, he refused since, as he said, he was getting money from AHS no matter what. He called their authorization department and told them we wanted him to fix a stereo speaker that DirectTv had damaged, none of which was true. I had to call AHS and explain what actually happened. They assigned Sun-Tech Electric. "The Resolution:" Sun-Tech did what Serra refused to do -- address, find and fix the problem. Heath at Sun-Tech was professional and efficient. If you use AHS, tell them you won't accept Sierra as a vendor and to send Sun-Tech instead. read more

How many electricians does it take to fix a bathroom fan? Four: One to diagnose the problem. One to forget to order the part. One to show up, but leave the part in the office. And the last one to arrive an hour late to finally fix it. If you love calling companies to follow up on the status of your repair, look no further, Sierra Electric is the choice for you. read more

So not happy with their 'service'. Made an appointment a month in advance and confirmed the business day prior. Was told they would be by between 9 and 12. 11:45 I get the call that they won't be coming because they took a different job but the could reschedule me for a couple days later. There was a reason I called a month in advance. Would not recommend. read more

We had an electrical emergency on a Sunday afternoon and called our home warranty company who sent out Sierra Electric. They were wonderful! He asked for pictures of our braker box so that he would be sure to have the correct parts to fix. He was knowledgeable and courteous. He fixed the problem and was out within an hour. I would definitely recommend them to anyone! read more

I had a stellar experience with this company and did not experience any of the things that the one-star yelpers mentioned in their comments. One yelper mentioned looking at the BBB website. While this company is not accredited with the BBB, they have had ZERO complaints with the BBB in the last 3 years. My Home Warranty had Sierra Electric (Mister Sparky) come to my home to address an electrical issue. Rene came to my home at 315pm (window I was given for a technician to arrive was between 3-5). He was in uniform, clean cut and very professional. He was extremely thorough in trying to find the problem and very informative (in layman's terms). Because of the nature of the problem, he was unable to locate where the "break" in the electrical current was coming from. He informed me of all of the possible solutions and that he would have to contact my Home Warranty to approve the additional work and come back. I received a call from the scheduler at Sierra by the next business day informing me that the Home Warranty approved more time to find the problem and scheduled another window of time that the same technician would return (3-5). Again, Rene was at my house at 315 and he brought a Master Technician with him in order to expedite locating our electrical problem. Within an hour, they were able to locate and fix the problem, which it was discovered that another electrician from another company that had just performed work in our home had created the problem. I am so thankful for these guys at Sierra Electric and I WILL have them back to my house for any electrical issues/needs that I may have in the future. read more

One local electrician failed to return calls and emails, then another one failed to show up at the least minute. But no worries, because Sierra Electrical Services came to our rescue. Polished, professional and best of all, they responded promptly to our request for sane-day installation of numerous lighting fixtures, two of which required a scaffold for a twenty foot ceiling. Thank you, Xavier, and thank you, Renee. Finally we know where to turn when we need really good and well qualified electricians. read more
