If you have the extra money, put it to GOOD use!

We have had the unit for about 10 months. It now tests twice a month for 10 minutes self checking and keeping the oil moving around. We had an outage the week after it was installed while we were away. I received a notice of it working, via the app, as it was supposed to do. We have had two other outages last year. The unit performed perfectly. So far so good! I had a year of complimentary wireless coverage. I just signed up for the next year. While not really a cheap benefit, it is nice to have. I may change to testing once a month later. We used to have outages every other month around my neighborhood due to weather, trees and old lines. Consumers has done a good job of cleaning up the lines and overhanging trees. The outages are fewer now, but as an older person, I now join the group of people that are more susceptible to cold, heat and less flexibility in dealing with the inconveniences of power outages. Our Generac should make things easier!

Great longevity, NO issues for 20+ years

I live north of Buffalo, NY and we get some wild weather. 20+ years ago I had a 13kw partial home Generac generator installed I never had an issue with its operation for 2 decades. Due the age of the 13kw and hours I had on the unit - I added a manual hour meter; it was time for an upgrade. I chose the 18kw whole house with external whole house transfer switch. The dealer arrived with 2 installers and 3 electricians and knocked out the replacement installation in about 6 hours which was remarkably fast. It was also tiptop work and passed the town electrical inspection quickly. The new 18kw whole house Generac is totally next generation with the app connectivity, ease of access for service, upgraded all aluminum cabinet, sloped top to assist snow removal to the front of the machine away from the rear air intake and the included battery and oil filter heater and an AGM (absorbed glass mat) battery, not a standard lead acid battery ensuring top performance in very cold weather. The green status light on the side and even on the air intake is huge improvement as well along with app. The whole house function is worth the investment because I no longer have to guess which circuits are powered. My only concern is that the rear located air intake is a little too low to the ground for my comfort. The rear air intake is only 16 inches off the ground (see photo) and we can get 24 inches of blowing, drifting snow fast. With the low air intake could potentially get blocked with snow. I'm mulling some sort of a DIY snow guard near the air intake on the back of the generator. Perhaps a drift fence on both sides of the generator about 2-3 feet away. I also enabled a 7-year warranty on the new 18kw Generac as part of a promotion, a definite plus. Based on my 20+ years of Generac ownership and after seeing the remarkable upgrades on the 2026 whole home 18kw Generac unit I can enthusiastically endorse Generac automatic standby natural gas generators without hesitation

The WiFi doesn't work. It never did. I did everything I could on the home end of things but no dice. This also happened on the second unit as well (I purchased two). So I'm sure it's a good unit but it does me little good if I can't “see it” without actually going to where it's located and popping the hood. Maine winters make that an issue.

We love our Generac!

We had our Generac installed during the winter. The process was handled with care and patience. We have family and friends with Generac home generators and we heard nothing but good things about them. The generator is turned on remotely once a week to make sure everything works properly. It's so good to hear it running and to know it's ready at a moments notice.

No more power worries

I just had this whole house generator installed to my delight. It works seamlessly with household with low noise level. I can run everything in my household without interruption. The only difficulty was using their APP since we are not very Teck savvy.

Reliable backup

If the power goes off during a storm it is sure nice sitting in the dark for 20 to 30 seconds and then the Generac fires up and our whole house power is back on. The only way to tell when the hydro power is back on is when the Generac shuts off without any interuption of power.

Generac's fine. Stay away from ACS Home Svcs Tampa

I am very satisfied with the unit itself, however I would never recommend the company used for the installation. They were the worst, most disreputable company ever (ACS Home Services of Tampa Florida) It took us 7 months to get it installed after signing the contract, and they demanded payment in full before they would even deliver the unit to our house after a $1,500.00 deposit at signing.

Love my Generac

I had this unit installed last year. I am so glad I did, and as a widow, it has removed a lot of my stress when the electricity goes out. My knowing that the Generac unit will come on in a few seconds is such a comfort to me. It will run the whole house, lights, A/C or furnace, appliances and the garage door.

Had this installed on 4/8, today is 5/20 and it still has never been working. Generac has been no help whatsoever, they're more concerned about selling their next generator, than trying to replace the lemon they gave me with a new one. I do not recommend at all!!

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.
