If you want to replace or install a generator in your home, reach out to our team. We can recommend a high-quality generator that suits your needs, budget, and household size.

Professional Generator Installations

Our team of professional electricians can safely set up wiring, plug your generator into the transfer switch, and can wire it directly into your service panel. Doing so will ensure that the electricity is delivered safely into your home, preventing your generator from getting overloaded. Failing to install a generator properly can result in back feeding, fires, and other safety issues. Professional generator installations are also essential to prevent carbon monoxide poisoning.

Our team of electricians will inspect your current electrical system and help you find a generator that best fits your needs and your budget. Then we will thoroughly explain the installation process and its cost before any of the work begins.

Contacted them after an emergency and the team was not only prompt, respectful, and friendly, but were very hardworking and kept us updated every step of the way. We really enjoyed working with Jeff, Chris, and Julian. There's still follow up to complete everything, but they made such a stressful situation as chill as possible!

Alex arrived on time at 8am, went over what was going to be done and got right to work. Worked straight threw till job was done, 2pm. He cleaned up mess from cutting into drywall before leaving and then went over what he did. As always, Mr Sparky and their crews did a great job.
