"PowerUp electrical was very professional and came out numerous times to help a strange situation we had with running electric to our hot tub on our new build house. They were very helpful and did not even charge us for the return visits. We really appreciated using a company with such integrity and great work ethic."

"Within minutes after submitting an inquiry, Seamus contacted me to find out specifics of my project and although he provided an estimate, he was receptive to coming out for a site visit before I committed. Edward came for the preliminary site visit and afterwards, I accepted their proposal. Cliff, the installer, communicated with me with scheduling and was very professional and easy deal with. Edward performed an inspection after install to make sure everything was done properly. The people representing this company seem very knowledgeable about their work and is backed up by generations of experience."

"Gentleman who owns Solarize was professional and courteous. He communicated well with the manufacturer and convinced them that a replacement inverter was needed based on the data he saw and the manufacturer had seen. It's what we were hoping for."

"We have had a hard time getting our Nest Video Doorbell installed because of the chimes that came with our house. After installing the proper transformer we could not get the Nest to work. I reached out to Home Advisor and HC Design was on the list of companies to contact. Before I could reach out a few companies reached out to me by leaving messages. What set HC Design apart from the others is Cornell not only called but sent me a text message after 11pm which told me he is really about getting the job done. I responded at 11:45 pm and he texted me back after midnight saying he could get our doorbell in later that day. I was definitely sold on Cornell and HC Design. The price was right! Mark showed up, immediately identified the issue, proceeded to install the doorbell and all within 45 minutes. Mark is friendly, knowledgeable, professional and just a really nice guy. Cornell followed up with a phone call since he was unable to make it due to being delayed at another job. I am definitely going to hire HC Design again for a couple other jobs we need done. Thank you for making this a pleasant and successful experience!"

"Tom from Synergy did the bid for under cabinet lighting install, however sent someone else to do the job. Originally discussed with Tom that he would use a regular converter box inside the cabinet and place a dimmer switch on the wall, but the other guy he sent wasn't aware of this and placed the dimmer converter in the cabinet. This has resulted in us having to use the dimmer switch inside the cabinet instead of on a wall switch -- not what I requested. Also, I discussed with Tom installing an additional outlet in our kitchen during the bid process. After he left I noticed he did not include that on the written bid. The guy he sent didn't know about it either. The outlet was installed however. Overall, I was charged $95 additional over the bid and didn't get exactly what I wanted in regard to the dimmer switch for under cabinet lighting. Both electricians were very nice and professional, but there was definitely a communication problem in regard to the installation of the under cabinet lighting. Perhaps I should have clarified the issue more strongly, or perhaps I didn't understand. Either way, I'm happy with the lighting overall, but not 100%."

"The owner of Electronics 9-1-1 installed an eight-camera home security system in my home. The entire experience, from initial consultation to finished product, was the model on which all other advertisers' services on Homeadvisor should be based! The company owner's recommendations about installation techniques, technical knowledge and considerations, equipment capabilities, scheduling accommodations, and modifications in mid-installation to overcome unforeseen issues were all spot-on, and resulted in a system that exceeded every expectation. Would use Electronics 9-1-1 again in a heartbeat, and it is a pleasure to recommend them to anyone needing security system installation or service of the highest quality."
