"I would highly recommend Resolute Electric. Klaus contacted me very quickly after my initial request and came to the house to assess the work request. I had two rooms that required different ceiling light installations and Klaus provided me with several different options for each install. The work was scheduled promptly and completed with the upmost professionalism and care. Klaus explained the work being performed as he went through each project enabling us to get the exact install configuration (type of light/bulb, positioning, switch options etc.) we required. The work was done patiently, not rushed and we were consulted throughout the day. Pricing for the work was very reasonable and as quoted i.e. no surprises. The quality of Klaus's work was exceptional and I'm extremely happy with the installations. I will definitely use Resolute Electric again when I need another electrical project."

"I was pleasantly surprised at their careful and thorough approach to the installation. They also were the most competitive bid with Cropp Metcalf being $3000 higher with less equipment. They are a local gem in a crowded field which should not be overlooked by savvy consumers"

"It went very well, he is a licensed electrician and he changed all of my old s12 sockets to energy efficient sockets so that I could use my electronic devices and not blow circuits.  I was being charged each time I called in a help ticket.  So I called Mason Electrical Services and had him come out and take a look . He came out and took a look at the problem and gave me an estimate .and I was really satisfied on the price.  He arrived promptly on 8 March 2014 had everything he needed to work with, and completed the work it only took a couple of hours and the job was done.  In that time he installed a ceiling fan in my bedroom with a remote.  He didn't make a mess.  I would definitely recommend him to others needing electrical services in the future.

Generator Install FAQs, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

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

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

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

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.
