Rated 5 out of 5 by from Awesome peace of mind! T&M Services did a great job! I am so happy with Generac at this point. You keep improving and making them better. Ya, it is not cheap, but trust me, worth every penny. I was without power for 6 days in TN due to an ice storm. Never again! I wonder about the countries infrastructure and fear this may be more common than it was in the past. I don't need to think about it anymore. I'm not trying to scare anyone, it was just a choice that was right for me. Generac is an amazing product and I am really happy about it. The wifi connection and ease of how it works. Automatic, you don't have to do anything. I have a portable generator that helped me get by, forget that now! Go for it!!

Rated 4 out of 5 by from Overall does the job The Wi-Fi isn’t free. The module is but the app required to utilize is 50 dollars a year. Not worth the features it provides. Very dissatisfied with the Wi-Fi aspect.

Rated 5 out of 5 by from Whole house Generac for peace of mind Contracted with PACE Electrical for the installation of my Generac whole house generator. They were a pleasure to work with. They seamlessly coordinated the gas supplier and gas service installer and their staff arrived on time. The installers from PACE were efficient, professional, neat, and took the time to answer all my questions during the installation process. My Generac started the first time and, after set, up did it’s own test run flawlessly. I would unconditionally recommend PACE for anyone in the DE/PA/MD region. I trust my Generac generator will live up to its reputation.

Rated 5 out of 5 by from No more Worries This product is everything you can hope for. It certainly takes a lot of your mine in case of a power outage especially during a storm/ hurricane. I don't have to worry about filling up gas cans, and preparing my portable generator anymore, along with running extension cords .
