"Phoenix electrical is owned by Paul, a master electrician, who does the initial consultation to figure out a quote, he is very direct and honest but easy to talk to and work with. Their customer service is excellent, they kept me well informed throughout the process and were very friendly and accommodating. Pheonixs quote was fair without question, his crew had a tough job installing a generator transfer switch kit set up, I live in a house built in the late 80s, so, the electrical system is a bit older and they ran into issues but they worked non stop and persevered through the challenges, found solutions, and completed the job as promised. Without question, I recommend Phoenix Electrical, and I will certainly seek them out first for any future electrical work. Thank you."

"We had to have our whole system replaced. The install crew was fantastic, professional and on time. They explained the new NEST thermostat so even my wife understood its functions. We have bi-annual check ups to ensure system operation is good for the dual fuel heat and a/c system."

Generator Install questions, answered by experts

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.

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.

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. 

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.
