"The Serviceman was on time. I had questions about the humidifier, which he answered thoroughly. He corrected a small issue with the A/C and the circuit breaker box as well. He went over the entire install from A to Z. We feel safe and secure with the knowledge that absolutely nothing was overlooked."

"Jordan Blake from Exceptional Electric rocks! His communication prior to coming out was very thorough, and he was able to schedule us in two days. While he was onsite he found multiple items from years of DIY wiring, one major one. He clearly communicated al recommended changes to better match current code. As to the major item, he discovered the transformer was causing over-voltage delivery into our main! He had me call United Electric, and the linemen were out even before Jordan left – kudos to U.E. Cooperative – and replaced the transformer on the pole. All this for what started out as just putting a new 30A circuit in for a mini-split! Our mini-split is not yet on site, so we look forward to having Jordan back to the farm to complete the electrical plus a couple of the found issues next week. He is so knowledgeable. I highly recommend him. His sense of humor is also a delight, and my husband enjoyed learning and discussing many things with him. His prices are excellent."

"We had several items for Dean. He installed 2 ceiling fans inside the house and one on the deck. Then, we had at least 10 outlets to be installed. We can't say enough about him. He was prompt, professional, skilled, available to answer questions and incredibly helpful. He was careful not to make a mess and cleaned up everywhere he worked. Plus, his prices were way beyond reasonable. Anytime we need anything electrical done or have friends that do, we will not hesitate to call him. All we can say now is, THANK YOU."

Generator Install questions, answered by experts

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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. 

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
