"The technician showed up timely.  He worked quickly to install the units we requested.  We had 4 sets of lights installed in two different segments of our basement.
The work was done within about 3 hours.  
My husband is happy with how fast and professional the technician was.  
The price was a little salty but that was our choice to spend the money because we just didn't have the time to do it ourselves.  
We are happy with the service and would recommended it for people that are similarly situated.  
I would call them again for future work.

"I had 3 different companies tell me my Generac home generator was beyond repair including Generac themselves. Brian from Powerton showed up and methodology troubleshooting the problem removed the entire engine and found then problem. He is extremely knowledgeable and persistent. Wonderful to see a highly skilled technician rather than someone who says just replace with a new one. I would highly recommend this company. If all their technicians are as skilled as Brian this place is AAA++. Thanks so much"

Generator Install FAQs, answered by experts

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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