"I recently had my generator repaired and serviced, and I was very impressed with the quality of work. Johnny was professional, knowledgeable, and took the time to make sure everything was running properly before he left. My generator is now running great, and I appreciate the honest, reliable service. I highly recommend him for generator repair and maintenance needs."

"Creekside Power is outstanding for electrical work!! The attention to detail put into their work when installing my Generac home standby generator was first class. I am pretty OCD about the way things are done, and Shawn s work was definitely up to my standards. I would highly recommend Creekside Power their price was my second lowest out of 14 estimates... Shawn was only $125 higher than my lowest estimate... and that person was not trained & certified to install Generac products, nor was he a Generac dealer like Shawn... that made my decision very easy. Everything was completed in a neat and orderly fashion. Shawn was very patient throughout, taking the time to answer my frequent questions. He used a level throughout the install and took his time as a result, everything lines up and matches up with my existing breaker box, etc. Shawn was very careful, diligent, and a bit OCD about how straight everything was during our install, which I thought was great!! Shawn takes pride in his work and it shows! Call Shawn for a free estimate... Shawn knows his stuff and you will like him. He did a great job for us on two jobs - a backup/standby generator install and a replacement of my meter channel!! He also ran a new electrical line to an out-building at my mom's house. I have already recommended Shawn to anyone I know who mentions wanting to get a generator installed."

"Pleasure to work with on recessed lighting install. Ken was responsive to questions and time changes via email/phone. We removed the old lighting, did some of the recessed lighting layout, and obtained the materials (he reviewed to make sure it was OK). His installation and electrical work was handled professionally and on schedule. Any adjustments were reviewed with me as a courtesy. We thought the price was fair for the work done. Nice job."

"Owner Chris W. came out for the free quote; he listened carefully to our needs to determine costs. James and Chris (not the owner) were prompt, professional, and kept us advised throughout the install process of our two bathroom fans. They also did some wiring upgrades downstairs in quick fashion. We would highly recommend Empire and anticipate using them again. Very good value for the cost."

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

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. 

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.
