"One thing I really liked about his work was the attention to detail and he made sure things were done right, not just fast. He goes out of his way to make the installation easy to work on in the future if need be. And it is very neatly done."

"We had Nathan from Ufema Electric complete a rewire of our entire finished basement. He provided a comprehensive estimate in a very timely fashion. The estimate was reasonable and Nathan was able to complete the job right away. We found him to be not only very skilled, but extremely polite, and respectful to our home - great job cleaning up after each workday! We are very happy with the results and will be using Ufema Electric in the future for any electrical needs. I would highly recommend Nathan and Ufema Electric."

Generator Install FAQs, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
