"Jeremy is an incredibly efficient, kind, and hugely capable electrician. He spent the day at our house with his helpers installing a generator, and he dealt with every single problem that came up cheerfully and efficiently. I would highly recommend him to anyone for any size job. He makes himself available for any problems and is just overall a terrific person, who is extremely good at what does."

"I called Cawiamca furnace service from home advisor. From the time they discovered the problem my furnace was leaking CO2 into my house only to discover many cracks inside the furnace and SAFETY Was first priority. The next day the furnace was delivered and installed and old one taken away. Of course I had a hardship and this company worked with me. The guys were very polite clean and very neat. This is my first time with this company I will have them for all my furnace needs. They were all very prompt in showing up on the job and eager to start work. GREAT COMPANY AND HIGHLY RECOMMENDED!!!!"

"The electrician Kyle was professional , honest and affordable. He was punctual and courteous. I hired him for the wiring and panel upgrade but I requested he change my six GFCI outlets and check the older outlets. He checked the outlets that I was worried about -they were good. He did need to replace a different inside outlet and 2 of the 4 outside outlets. He was kind and explained why they needed to be replaced. One just was no longer working. The other 2 were not up to code actually were a fire hazard. I am female senior citizen grateful I hired Elevate Electric."

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.

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.

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. 

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
