"Share review Embed review Write an update Edit review 12/1/2020 I am very pleased with the service I received today from Electrical Technician Bogdan Ovsyychuk and his assistant. He replaced overhead lighting in my kitchen at a very reasonable cost and I am very happy with the result. They both were also very friendly and personable and wore masks and all other necessary protective equipment. I highly recommend them for electrical work!"
Our team at Bonney helped restore flow at this Sacramento home by performing a sewer spot repair on the main line for our customer.  This involved locating the problem area, digging the trench, snaking the line to clear the drain, repairing a section of the sewer pipe, and then backfilling the space to restore back to the original landscape.

"It went very well; the thorough HVAC system checkup revealed some questionable component that were best suggested to be replace with new ones. I am not confident that my HVAC system is set for more that good performance going forward. I appreciated the non-pressured advice and suggestions in coming to my decisions. Thank you, Joaquin Ortiz."

He was very professional and following the Tune-Up asked if there was any other items that needed done or looked into that he could take care of. His services were very much appreciated and very professional. Lee"

"I have an old pressure relief valve replaced today. the service person was great, and the installation went really well. My main complain was the price after I did an online comparison. usually, the PRV installation will cost around $500 on the high end, but Bell Brother charged me $1600 since the new valve does not fit the old pipe, and they needed to redo the pipe. My family has been using bell brother for many years, we trusted their workmanship, but the markup is just too steep to justify. I definitely learned my lesson, for small jobs, will use home-advisor instead."

"Called these guys for what I thought was a Nest issue, and they discovered that my heat exchanger had cracked and I was better off replacing my very old unit with a new one. They provided me with a proposal the same day and I decided to contact a couple other companies for comparison. They confirmed Jazz's findings and provided me their quotes as well. Jazz's bid was very competitive and I was happy to give them my business. On install day, Jazz showed up with two other gentlemen and they wrapped up the installation in one day. System works great. Thanks so much Jazz!"

"Computer had been acting up for a while but I kept putting off getting it fixed.  After reading all the great reviews, I decided to give N.A.T.S. a call.  So glad I did.   Jim was able to resolve all my problems remotely - no drop off or pick up necessary - so convenient!  I feel like I have a brand new computer, it runs so well and FAST too.  I couldn't be happier and wouldn't hesitate to use his services again.  My only regret is that I didn't call him sooner.
