Generac 7043 Home Standby Generator Review

by Charles Jasper

Product Overview

The Generac 7043 Home Standby Generator is the biggest air-cooled generator currently on the market. Although pricier than many others, this generator boasts, reliability, ease, and high-value service. This particular model was even rated best standby generator for a whole house.

The item is 515 pounds and 120 volts, and the dimensions are 48 x 25 x 29 inches. The generator by itself costs a little over $5,000, but after paying for shipping and installment materials and labor, the total comes out closer to $10,000. It is certainly a large home improvement investment, but with its good reviews and high ratings, this product deserves to be on your list of potential candidates for a new home generator.

The Generac 7043 Generator’s unique design includes removeable panels, efficient wiring, and a base that is requires minimal preparation on the surface it is to be placed. These features cause this model to be significantly easier and more cost-effective to install while still providing reliable service to its users.

Is it reliable?

The total cost of the unit, including labor and materials for installation, should be about $10,000. Keeping that in mind, you need to know if this model is going to be worth that investment. Is it reliable?

Reliability is perhaps the most important factor to consider when investing in a generator. The purpose of having a generator is to have a back-up in emergency situations. If your backup fails, then what is the point? An unreliable generator can be a large waste of time and money. Remember that any generator that you buy is going to be expensive, and you need to make sure that the investment is worth it in the end.

Based on most of its reviews, it seems as though this generator is a solid pick in terms of reliability. Although there are a couple sour reviews mixed in the middle, a vast majority of the reviews sung the praises of the product and highly recommended it to potential buyers.

What issues have people had with this generator?

Even though most reviews of the Generac 7043 were glowing, there was a significant portion of 1-star reviews, and this shouldn’t be ignored. Disappointed users discussed issues with the battery, noise, installation, and even sometimes noted that the generator reacted in a dangerous way when being used.

Noise is a factor that should be taken into consideration, but as the generator is only used as a backup for the house’s power, it shouldn’t be one of the main contributing factors when deciding which product to buy. The generator will only run when the main power source for the house goes out, which is hopefully very infrequent. Having a little bit of white noise in the background is undoubtedly preferable to being stuck in the dark without electricity for hours at a time.

That being said, no one wants to pay thousands of dollars to get rid of one problem only to introduce another. The Generac 7043 is said to produce about 80 decibels of sound, which is not insignificant. It’s best if you are able to store the generator in a space that is away from the living space so that the sound will not interfere and be a major inconvenience to day-to-day living while the power lines are being fixed.

Apart from the noise complaints, there were a handful of sources claiming that the battery had issues. Apparently, their generators would not run for more than a couple hours at a time. Other buyers complained that the way the generator was wired had become a hazard to their home. However, this may not have been entirely the fault of the product. This generally seemed to be an issue with the installation, and not with the product itself.

As with any product, there’s also bound to be a faulty generator or two out there. However, most of the issues that occurred seemed to originate from the original installation. Make sure to hire a reputable company to install the generator, and you shouldn’t have any big issues. If you’re still experiencing problems, there is a warrantee on the Generac 7043, so your losses will be cut to a minimum

Customer Service

If you’re worried about experiencing issues, this generator can help solve that. The company provides 24/7 phone support every day of the year. The manufacturer, Generac Guardian, has dealer locations across the country to help answer questions and provide any services you may need.

Although there is a warrantee on the product, many people claim that getting a refund or a new generator was not as smooth of a process as they had hoped. There is apparently a fee associated with making a claim and getting someone to asses what is wrong with your generator. This is something to keep in mind as a potential future cost.


  • Reliable service
  • Cost-effective installation makes up for some upfront costs
  • 24/7 Customer Service available
  • Wi-Fi included
  • Low maintenance over long-term usage


  • Should not run for over 24 hours at a time, per the manufacturer’s instructions
  • Only one way to charge the battery; no external charger available
  • Battery charger only works when the generator is not supplying power
  • More expensive than most models (about $10,000 including installation costs)
  • Must pay a fee for warrantee

The Generac 7043 Home Standby Generator might be more expensive than other options, but it is still worth consideration for interested buyers. Many of the upfront costs are partially made up in the easier installation and low long-term maintenance, and the new technology lends to more reliable service, which is incredibly important when making such a large investment to improve your home.
