Excellent service and very knowledgeable. Mr. Engleton was very professional and easy to talk to. He answered all of my concerns with impressive details.Thank you,If and when I need something done in his line of work I will be calling him again.

Reasonable price, very respectful .and clean. I strongly recommend. Specially if you have any electrical issue after hurricane.

Timely, and communicative. Will use again for my next project.

He is a very honest man and he gets the job done at reasonable price. He goes beyond and over to make sure you happy with the results.

We lost power in our house last night , called the Electric Doctor company. A tech came out to see what the problem was but did not have any of the necessary tools but made sure to charge me $280 just to come out. I asked for a quote to fix the problem and he gave me a quote for over $1600. I googled the parts that he was going to need for the job which was not over $200. So he is wanting to charge $1400 for labor. Requested another quote from a different company and got it done for $500.It's not nice to take advantage of people. I do not recommend this company.

They did a great job! Very professional and on time. We will definitely continue to use them.

THEE worst company ever. DO NOT USE THEM FOR ANY SERVICE!! We called on 2/13 tech was suppose to show on same day, didn't show up until 2/15 because they were so behind tech goes out to location and notifies us that he needs to order a part and takes off. Today 2/20 I called the office to get an eta on the part and when the tech will come back out to service our compressor. The office team are CLUELESS. Part had not been ordered nor does the office follow up on the next service date but sure will give you an estimate price on what seems convenient to them when they have NO IDEA what they or their techs are doing. DO NOT USE THIS COMPANY FOR ANY COMPRESSOR SERVICE!!!

Jolt installed a whole house generator for me. I paid for the generator upfront which was ~half of the cost, then the balance after install. Marilu took care of the administrative part dealing w/ permits & CenterPoint Energy. Vladimir handled the install. They both did a great job & made the process as painless as possible. They're also both very friendly & great about addressing any questions or comments I had.

When our central air conditioning unit was not cooling well, my neighbor said I would save a lot of money if I called T&Z All Services in Houston. He explained that they had a handyman for almost anything and many of them were tradesmen who were semi retired or working independently. He was right. A very skilled technician showed up and fixed the leak I had and charged me a very reasonable fee. They also guarantee their work. I will call them again for anything that needs fixing. When we need handyman services for our Houston office building we rely on T&Z All Services exclusively for all repairs. Whether it is electrical, plumbing, roof repair, locksmith services on practically anything else, they are the company we call. It is fast and reliable. We have been using them for years.

Worked there not worth working for.

They did the original electrical work as hired by our builder. They are rude and arrogant. My guess is they know what they are doing but they are not service oriented. Very disappointing.

I would give 0 stars if I could... Owner Mr Davis has no respect. Over priced

Great company and friendly people. Great pricing.

Sigma has provided services for the business I work for before. Dave was a great technician. The owner, Thomas, however, is another story. For some reason, the admin at the time, misplaced an invoice ($100-something) and it went unpaid for 2 years. Sigma and Thomas never reached out to us for payment so imagine our surprise when we made another service call. Thomas chewed out our new admin (who wasn't even employed at the time of the last service call) and decided he needed to pre-invoice us. That's fine. The technician came out for 10 minutes and we were billed for an hour and a half. We called back to see if we'd be receiving an updated invoice and Thomas informs us of his time minimum. We agree to pay the invoice and Thomas replies, Well if you look at the first invoice that ya'll didn't pay for 2 years... Why the hostility? We already apologized for the missed invoice and agreed to pay the minimum on the new invoice. It wasn't like we were always delinquent. It was ONE invoice out of how many times we've made service calls with Sigma? Why didn't your accounting department call us to reconcile the invoice in the last 2 years?
