"Chris was outstanding! I had a simple idea, but it required his expertise to upgrade my electrical panel and install a 30-amp outlet in the garage for my RV. Thanks to his work, I can now easily power my Casita trailer whenever needed. Chris was professional, efficient, and left everything spotless. I highly recommend him!"

"DC LLC/Chris McDaniel did an outstanding job for NNMC's El Rito Campus. They pulled electricity to our greenhouse and installed irrigation systems at both the greenhouse and our rain gardens. From start to finish, their work was top-notch ? knowledgeable, professional, and thorough. What really set them apart was how well they worked with our facilities team and how they kept communication open throughout the entire project. Chris genuinely cares about the quality of his work and it shows. They were helpful, responsive, and a pleasure to work with. Highly recommend DC LLC for anyone looking for a reliable, skilled contractor. We couldn't have asked for a better experience."

"Hired A Security Solution to install fencing for me. I was so pleased with Erik and the work his guys did that I have now hired them to remodel my 2 bathrooms, install laminate wood floors in my whole house, and build a planter for me. The cost is very reasonable and Dawn their interior decorator has been super helpful with designing the bathrooms all while meeting my needs and wants. Great company! I highly recommend them."

Generator Install questions, answered by experts

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.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

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.
