Watts Up was prompt and dependable in responding to an electrical panel upgrade that was needed before a solar system could be connected and used. Tim is very professional, skilled and efficient. Will hire again in the future. Appreciated him coming back out when the utility did their work to ensure all went smoothly.

Watts Up offers very skillful and value-added services. Tim is a gifted and knowledgeable master electrician who is very concerned with the quality and safety of his work. I have used him consistently for over two years now. He is not the cheapest, but you do not want the cheapest when you are doing electrical work.

Best electrician i have ever had experience with. He was always on time, was never lazy, and always worked late to get something done, at the owners convenience . As i have had experience with other electricians, he is by far the best. no need to wish you good luck, with him you will find it.

Tim Mullan is the man. He hooked up our house with some much needed outlets and then our RING doorbell. He was polite, timely and is dedicated to his craft. Taking great pride in the aesthetic appearance of the outlets etc. will use Tim for all our electrical needs.

I would recommend Tim and his company Watts up for any and all of your electrical work. Owner and service provider Tim is a Master Electrician that is knowledgeable and easy to work with. All work is explained fully and he gives all options and scenarios to give you the best outcome possible. He won't BS you either and gets right to the issue at hand and finds you the best value as well! Whether Commercial or Residential this is your last stop for electrical work!
