Well spent money.

Love my new Generac, I feel so much better knowing that I’ll have power during a power outtage. I live alone and it has given me a great security knowing I’ll taken care of. The guys that installed it was fantastic!!! Very VERY professional. I highly recommend GTI Generac power systems.

Excellent Great installation, look great Very impressed with the Installers effort to evaluate our power requirements He contacted the local utility company and found out our average and peak power utilization from the past two years and installed a system that will totally support the whole house

Love our Standby Generator

The ease of installation and use is impressive. It runs its maintenance check on the scheduled time once a week and I check the status. Our power outages are frequent enough that we felt having one was beneficial than not. I’m thrilled each time it kicks on within seconds of the power going out.

Peace of Mind and Reliable

Having experienced "Snowmageddon" in North Dallas a few years ago and without power backup, this new Generac whole home generator brings incredible peace of mind. It's good to know it is always there ready to take over should the power grid go down. The only reason I gave it a 4-rating is because of the delay between power failure and the generator starting. I wanted Tesla's system mainly because of its ability to take over within milliseconds of losing power unlike Generac. If power is out for more than a second, then there are several clocks that have to be reset. I've had days when the power blinked multiple times thereby requiring clock resetting each time. Very annoying. If Generac would develop a battery unit to incorporate with the generator that would bridge the gap between the grid failing and the generator taking over, then I would definitely give it a 5-star rating. That's my only complaint, and it really isn't a Generac fault since it operates as designed. I just wish the design would change a tad to eliminate the time gap.

50/50 feelings

I wish I had better things to say but I feel the company that installed the unit did a poor job the unit leaks oil and when I told them about it on the 1st maintenance visit, they wanted charge me extra this was part of the installation and has been leaking ever since . Other folks may have a better experience with this brand I think it was just the company that has installed mine .

Great Features and Reliable

It has been very reliable and we are very happy with our investment and equally happy with Genesis Electric install and assistance! If you've ever been without power for a prolonged period, you know how important it is to have a backup system, and especially important as you age for safety reasons.

Best Home Purchase

I have had my generator for 1 year. Love it. Great investment. Peace of mind just knowing that it’s there. I have used it a few times, generator comes on seconds after a power outage. My home functions don’t skip a beat during a storm. Definitely recommend.

Survivability in a hurricane prone area

I previously had a portable emergency generator that helped me through a few hurricanes. I retired a few months ago & built a house on my rural property 100 miles away. Two years ago that area suffered a couple of bad storms & the community was without electrical power for weeks. I now have my own well & electrical system. Storms as we have in Southeast Georgia will not affect me as much in the future.

May not work in snow and wind

We had one installed on Cape Cod in Dec 2021, and it failed during a nor'easter in Jan 2022. Snow blows into the vents, melts, then refreezes on the air filter. Removing the air filter (as suggested by Generac's emergency service) just pushes the ice further down the power chain. Seems like a design flaw, to have no way to divert snow blowing in. When I called Generac to ask for a fix, they only offered to sell me warmers (for another few hundred $$) which may not work. Their attitude was indifferent; they claimed I was the only customer who had ever had this problem. That's a lie - my local installer had reported to them a hundred customers on Cape Cod with the same catastrophic failure during that storm. So this may work well for you if your climate is mild, but don't count on it during a winter storm with wind.

Satisfying to spend money on a great product.

Within ten days of the initial startup, we had our first power outage on Memorial Day afternoon. within ten seconds or so, our whole house was up and running on our new unit. It was a great feeling. A/C up and running, everything. It gave us a great feeling.
