"Needed outside security lighting installed. Vendor was professional and arrived on time. Cost was perhaps a little on the high side but it was worth it to me. Would consider using this vendor again."

"Kaidyn quickly identified and resolved the problem with a GFI outlet. He completed the safety review which identified a potential problem that should have been detected during a home inspection. Based on findings and my additional requests, Noah joined him and they quickly and efficiently completed raising pendant lights, replaced other outlets to meet code, installed an additional ground rod and surge protector. They also exercised care while in my home. I highly recommend McCormick Electrical Services!"

"They promptly installed two generators, one for each house, and walked through the app install. They called me a year later to schedule yearly maintenance. Great all the way around."

"Very competitive quote/estimate. The scheduled install was accommodating. Alternatives were explained and helped me to avoid unnecessary expenses. The owner/installer (Alex) was very knowledgeable and did a satisfying professional job. I will certainly have a few more needed repairs done by Apollo. I would highly recommend Apollo, even if it is your only estimate/quote. Apollo left with the job site cleaned up."

Generator Install questions, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

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. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.
