"I couldn?t be happier with my experience with Security Safe Company and Jeremiah! From start to finish, they were professional, knowledgeable, and went above and beyond to make sure everything was perfect. They installed my new camera system, alarm system, and a whole home generator, and the quality of their work is outstanding. Jeremiah took the time to explain everything in detail and made sure I was comfortable with how everything operates. It?s rare to find a company that delivers this level of service and care. I highly recommend Security Safe Company to anyone looking for true peace of mind and top-notch service!"

"This company installed 7 new LED recessed lights and a dimmer switch in my kitchen. They were quick to respond with a quote that was reasonable. They showed up on time. The crew was super respectful of my space, cleaning up as they went along and very meticulous when it came to installing the lights to my layout specifications. I would definitely recommend and will gladly hire them for future electrical work."

Generator Install questions, answered by experts

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

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.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

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.
