Rated 5 out of 5 by from Very professional installation!! We just completed our installation of the 26 kw whole house generator. All of the work was done by Integrated Home Solutions. I can't say enough positive things about this team. They were so professional, efficient and neat. I would highly recommend this company for your Generac installation.

Rated 5 out of 5 by from Great product and Service Hughes Electric & HVAC installed this generator and did a fantastic job. They even stored the generator until it could be installed. Everything they did for us is so much appreciated. We were so impressed with this company that we let them install 2 new Trane units. We lost power 2 days ago and the generator worked great.

Rated 5 out of 5 by from Hard to get This product is as advertised and works as it should. I am very pleased with this generator and its operation. I am confident that I can rely on it to protect my electrical power requirements. The only problem I had was actually getting the unit and having it installed. The actual choice to buy was easy and the cost was acceptable for the security it offered and paying for the unit was easy but delivery was three months later and installation was another three weeks almost 4 months after I decided to install a generator. And the advertised 7 year warranty free was the final factor and I still don’t know if I have that warranty. I haven’t seen any notifications explaining my warranty or even if I have a warranty yet. I called my installer but they said that was provided by Generac and they would be sending me a notification and explanation of my warranty, but haven’t received anything yet so it’s another thing that I’m waiting for. So I like the generator but I’m not thrilled with the company so far.

Rated 5 out of 5 by from Excellent Product Had a Guardian 24kw generator installed about 1 yr ago by Ambrose Electric. Installation went very smoothly and has a very acceptable appearance. Initial oil change and service check is simple. Everything is easy to get at. We have had two short term power outages since installation and everything works pefectly. Our house is total electric and we have no problem living normally during outages. Well pump, water heater, clothes dryer and electric heat all operate normally although we do take care to limit burner/oven usage on the stove if the electric heat is in use, for example. The Generac handles it all with no strain. My one complaint is with the exercise program. It runs for only five minutes under no load. This causes moisture in the air to condense into the oil. Particularly in the winter. I spent 50 yrs as a Diesel and heavy equipment mechanic. Moisture in oil is never acceptable, despite what Generac claims. Originally set to exercise weekly I changed it to monthly and on those days I trip the main breaker to put the unit under load for 30-60 minutes. Unit is exercised and the oil stays moisture free. All-in-all an excellent unit and it is great not having to get up in the middle of a winter night, or any other time, and go hook up a portable generator.
