"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 hired them to come and install an exhaust fan as well as a thermostat. After realizing my hvac system also had a humidifier function that was incompatible with the thermostat I bought they were able to properly install my exhaust fan (I bought the wrong kind as well) and hung a chandelier under two hours. Very efficient and fair pricing."

"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

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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.

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.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
