A Generac standby generator is positioned outdoors on a black platform, with a white wall and shadow patterns from nearby trees in the background.

Dennis at Grasten was out today and did a terrific job performing scheduled service. He was very receptive to me hovering and asking questions as he performed the service. He treated my generator as if it were his own as he checked, explained, and cleaned various parts as well as performed the loaded run test while making sure the load shedding modules functioned properly. Thanks Dennis and your work is appreciated.

Trenched side yard - A trench runs along the side of a house, bordered by a wooden fence, with visible utility pipes and equipment at the far end.

This was an amazing experience from start to finish. Kevin and his team of professionals are top…read morenotch. I had multiple quotes from all the main Generator companies in Houston to install a whole home standby generator, including: Generator Supercenter, A&A Genpro, Generator Power Systems and Blaze Generators. Blaze was the least expensive and by far the best and most thorough quote I received. Outstanding value for money. Kevin was honest, completely transparent, and gave me the sense that he wanted what was best for my home and my family, rather than just making a quick sale. He got me installed within a week or two (other places wanted me to wait 2+ months), and the crew he sent was first class. One nice thing about Blaze is that they do not contract out their installation work. They have five full-time crews that have all worked for them for years. They left my house and yard looking better than when they arrived! Everything was put back perfectly, which is pretty amazing when you consider the amount of work involved in installing a generator like this. In short, I cannot say enough good things about Kevin and Blaze Generators. I will recommend them to anyone and everyone.

The beginning process was great, but here's the twist I paid to have the fist maintenance check and…read morenow I can't even get them on the phone . So they charged me for this service and they are t available. It should be a crime for this. And I recently found out they told us Generac was giving a 10 yr warranty that even shows in our contract but that was a lie per Generac so now I have to buy an extended warranty on my own that will be very costly now .
