"Installation was great and generator has run perfectly since. Their monthly service has also given us the peace of mind to know it will be ready when we need it. This is also the second home I have purchased a generator from them and they have always done a fantastic job."

"William was prompt, set expectations and followed through and educated us on the need for a Surge Protector. He came for a quote but was able to install the EV charger quickly and cleanly same day. He is very knowledgeable about the EV market and was in and out quickly. Great experience all around. Highly recommend!!"

"The man is truly amazing. His work is outstanding. He installed a whole house Generac generator for me and has since become an authorized Generac dealer and serviceman. I had 4 different company's give me estimates and he blew them away with a great price and fast service. Big company's put me on their waiting list. Some were up to 10 weeks out. He completed the job in 3 weeks. His work is clean and neat. One of his best attributes is that he is HONEST and does all the work himself with the aid of a helper, so you know that the job is done right. He is fully licensed and insured. I feel like I have an electrician I can truly trust."

"Work was done on time and professionally installed. The only drawback was the electrician did not clean up after the work was complete."

Generator Install questions, answered by experts

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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. 

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.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

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