Chris was professional from beginning to end. A pleasure to work with. Would highly recommend his services.

We were remodeling a house that was over 50 years old and was concerned about the electrical wiring. We found exposed and outdated electrical wiring in the attic, which is major no no. Our entertainment system and TV's were also plugged into outlets that were not grounded. We found Chris through a recommendation from our local handyman. We called him up and he was able to come the following day. Chris was able to explain the challenges with the current state of wiring and made recommendations. During the rewiring process, he patiently worked through a claustrophobic-type environment for hours on end, both in the crawl space and attic. It took about 2 full days to complete the job and made sure the area was clean before he left. He also sent before and after pictures to show the work he completed. On a side note, we also had a mechanical gate opener installed at the same time from a different vendor and Chris found the wiring was done poorly. He even went above and beyond and discussed with the gate installer to get the job done right, in which they complied. He certainly pays attention to detail, always thinking safety, and cares about his work. Chris is courteous, professional, and very knowledgeable about electrical systems. We'd hire him again in a heartbeat. read more

Called tonight expecting to leave a voicemail so that someone would call me back first thing in the morning. Surprisingly, Chris answered the phone. I explained that there was a loud buzz in one of the outside walls of my house. It had been going on every 1 to 2 minutes for an hour prior to me calling Caldera Electric. After 38 minutes on the phone, we figured out the issue was my pool pump/motor which kept trying to turn on. As a result of the electrical in the metal conduit, that was apparently creating the noise. I turned off the breaker and no more noise. Had thought we were going to have to punch a hole in the wall in the house. What a relief that we found the issue! Pool man is coming tomorrow. Cannot thank Chris enough for his patience and his endless questions which kept prompting me to continue to search for the source of the noise. THANK YOU!!! read more

I can't say enough good things about Chris, who recently completed a massive update of all the electrical wiring in our (old) house. He is thorough, explains things clearly, consults you often, makes suggestions without upselling you, and provides extremely clear and thorough estimates and invoices. He had some great suggestions for us that we were happy to take (tamper-proof outlets for our small children, a few spots where an extra receptacle would be handy), and he was really considerate, cleaning up after himself, patching, and even working on quiet tasks during our kids' naptimes. It was so appreciated, and made a month's electrical work go as smoothly as it possibly could. Chris's rates are reasonable, and he was also open to working with my father-in-law assisting, which helped keep costs under control as he discovered that our old house had way more problems than we'd known about before the walls were opened up. We're really happy with the quality of the work (it passed inspection with flying colors), and grateful to Chris for his stellar job! One of my favorite aspects of Chris's communication is his estimates and invoices. You can see a clear breakdown of estimated costs for various items (both parts and labor), and in his invoices, he shows you a comparison between the estimate and the actual cost and an explanation of the difference. It's awesome. I highly recommend him! read more

Our landscape lighting seemed to all stop working at once. Turns out there were multiple problems with disconnected wires, faulty switches and photocells, dead batteries and lights, and a bad transformer. Chris methodically worked through each of the issues with the skill of a detective and resolved each one. Would recommend him to anyone for any electrical issue. read more

Chris was wonderful. He was quick to respond to my phone call and he was able to come and fix my issue that same day. I needed him again the following week and he came right down and fixed my issue. He was a pleasure to work with and very reasonably priced. I will continue to use him!! read more

Chris Caldera did an amazing job today. He solved a very difficult problem caused by a sloppy/unprofessional work by a previous company. He was very thorough in his problem solving. And he never gave up to the challenge. I thought my electrical panel issue was a hopeless case. All I could do was pray that he figures out a way. Thanks to his experience, knowledge and dedication, problem solved. Best part is he saved us from more expensive repairs. Not to mention the risk of fire. I highly recommend Chris for any of your electrical repair needs. read more

We needed two new outlets on a wall to mount our new television. I had a few electricians come asses the scope of work. The other electricians came, looked at my wall, said they would email an estimate and left within minutes of arriving. The other electricians never even sent an estimate. I looked for other electricians in the Monrovia area on yelp and Caldera Power Services came up. I called and Chris answered. He stated he has a lot of work but is always willing to take on new customers. He came that night to look at our wall. He then looked at the attic and then worked his way into the crawl space beneath the house. To my surprise Chris had an estimate sent to my email within 12 hours of his visit to my house. I decided to proceed with the work. Chris Caldera did a fantastic job. He has a very calm demeanor and is an easy going guy. He seems to enjoy the work he does and he has made a lifelong customer in me. Caldera Power Services is the way to go. Thanks again Chris. read more

Ultimately I didn't use this company but the response time with an estimate was incredible. Awesome customer service.

Chris is knowledgeable! He taught me few things about gfci unit and how to manually reset the panel for the future reference. He was on time to my appointment and very nice person. Thank you for fixing up my place. read more

This is the first time we used the services of Caldera Power. We could not have been more pleased with the service and workmanship Chris provided. He arrived at our agreed upon time, he provided us with a written estimate, and he left the areas he worked on cleaner than he found them. I will recommend Caldera Power to all of my family and friends. Thank you Chris, see you whenever we have our next electrical issue. read more

Wow!! I finally have found the electrician I've been looking for! Chris does great work, is on-time, prices his work fairly and is meticulous. He installed two outdoor security lights and a programmable light switch all done with a high level of professionalism and care. For someone who is a perfectionist, I appreciate people who do the work right and Chris is one of those people who cares about making sure everything is working and looking right before he says the job is complete. I cannot recommend him more. I immediately scheduled him to do some more work after he helped me out. read more

Chris does fantastic work. I hired him for installation of new motion-sensor security lights around the exterior of my mother's the home, which also required running new wires and installing new junction boxes and switches. He also installed a new GFI outlet in the kitchen. Chris is extremely professional, personable, honest, thorough, organized, and tidy. The pricing for his services are fair and reasonable for the high quality of work he provides. Chris truly takes pride in his work, making sure everything is done right (and to code). It was a pleasure working with him. read more

Chris arrived literally 5 minutes after I called him! I randomly lost power in the middle of the night and he saved the day! He didn't mind me watching what he was doing and was very friendly and was willing to explain things to me. I highly recommend him! What he charged me was very reasonable. read more

Outstanding, professional work! Chris and crew are professional, personable, on time, conscientious with fair prices. This us our second time using Caldera Power Services and I would highly recommend this company for any electrical needs you may have including lighting and ceiling fans. read more

Chris provides excellent and honest service and I appreciate his willingness to respond quickly to an inquiry and his ability to fit a project into his schedule, even after 5 pm. Just this week I had an outdoor light fixture with an obsolete bulb, and Chris was able to tinker with a new housing so that we could salvage the fixture but update it with a newer bulb. Back in May, I had a long list of items for him to investigate, repair or replace, and he worked through that list very efficiently. What I especially appreciate is his ability to troubleshoot and offer options within different budgets (good, better, best). That's important for my apartment complex budget. He also identified a somewhat dangerous obsolete electrical wiring in a crawl space and was able to eliminate that problem. read more

Needed a 240 plug installed in our garage, and power run to it from the circuit box. Great work, super fast, and LESS than his quoted price! Hooray! read more

Chris returned my call within minutes even though he was booked for weeks out. He is a very professional and skilled electrician. He did a superior job of upgrading the electrical on our 1908 house. We feel so much safer with our new wiring. Not only did he give us a reasonable quote but he came in under budget. We highly recommend him. read more

Chris was awesome....he was very professional, thorough, and prompt. We had lost power in parts of the house, not the whole house, so I wasn't sure what electrician to contact. I went on Yelp and read the reviews, and saw he was close to my area. He came the same day and was on time. He was great...can't say enough good things about him. He is the man to call for all electrical services read more

I called Chris yesterday morning for an "emergency" installation of an outlet. I could tell he had a busy schedule, but he made the time to come out that very day. Chris is the consummate professional and I was EXTREMELY impressed. He even fixed a faulty outlet in my kitchen. I write very few reviews on Yelp but the quality of service compelled me to share my experience. Chris will definitely be my go-to guy on anything electrical related. He is top notch. read more

Chris has done work for my wife and me at our home, and most recently here at my office. We have always been beyond satisfied with his work, and have never hesitated to refer him to others. He is the consummate professional and operates with a conscientiousness that is very rare to find these days. The work he completed last week at my office was complex and required intricate configurations and wiring. The price he quoted and the time he said he would be spending at my office were spot on. Chris is a real find. read more

Once again Chris has come to our rescue! Chris has always been prompt, professional and does not stop until the issue is completely rectified. It is a true pleasure working with Chris and I highly recommend him to anyone having electrical issues. read more

Chris retrofitted our fluorescent lights to LED lights on 9 fixtures and did a great job!! Two lenses broke and he returned to fix the situation. He also worked on our hall light that was out. He found a short behind the fixture and fixed it. He was very professional in his work and was a joy to work with. He did everything requested at a reasonable rate. I highly recommend him. read more

Great service! Chris came in a very reasonable time diagnosed the problem and had my electricity back on track. I would highly recommend his company to anyone with electrical needs. read more

I was very impressed with the job Chris Caldera did at my home. He took the time to explain what the problem was and the best way to fix it. He covered everything near the light fixture with a plastic tarp, and after he completed the job he removed the tarp and swept the area. I was amazed. He was very thorough in checking to see that all was done correctly. I give him 5 stars and highly recommend Caldera Power Services. read more

I called Chris at 5:30pm on a weekday expecting to get a voicemail; he picked up, listened to my issue and even expressed empathy for the situation. He came out the next morning, kept in close communication about costs/estimates and potential options to save money! He worked incredibly hard through the heat and was clearly not cutting corners- he did things by the book, the right way. I would definitely use and recommend this company, they are honest, hard working, and professional. read more

Chris did an expert job installing garage lighting, running wiring through conduit and hooking the lights to a combo switch and receptacle. He showed up at the time he promised, completed the job with attention to detail, and cleaned up afterwards. I couldn't be happier with the work he did for me. read more

I needed an electrician to install a ceiling fan in the bedroom. There was no power source so he had to tap off the closet light. I had tried several times to find someone that would do this job, but never had any success. I decided to call Chris after reading all the reviews on Yelp and I am so happy I did. He responded the same day with an email estimate and was able to schedule the job in about a week. He arrived exactly on time, did an excellent job, and explained everything to me.. I am SO HAPPY...I finally have a fan and now an electrician I can highly recommend. read more
