"Did not use their service, however, they responded quickly to the Angie's List request for providers and gave an instant quote on site performing the estimate. Others, providers took up to two weeks for a final estimate. Very professional presentation and is a top rated service provider for their represented generator brand. Would consider them on future and/or add-on products based on my experience and their good ratings."
A win for the owners of this panel change.
Ready to label and get inspected
This is guaranteed to provide adequate electric needed to provide heating and cooling on demand.
Panels are installed and look great.
Without yearly inspections of your electrical services in your home this could happen to you. This is the panel that failed and we upgraded.

"If you want quality work, professionalism and fair prices, call these guys. I had a tree limb fall down on some electric wires that ran across my driveway and to my house. I called GT Electrical, pretty much during dinner but within the half hour he was there. And within within another hour had my electric back up and running. You cannot go wrong with this company!!!"

Generator Install questions, answered by experts

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.
