"Really responsive and prompt, especially in the installation phase. We did have a couple of small hiccups, which in my mind a homeowner should expected on literally any remodeling project, and they were resolved quickly. Communication on final details like inspections could have been smoother, but overall the whole process was very clear, well managed, and well executed. Happy with the choice to go with Red Rocks."

Generator Install FAQs, answered by experts

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

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.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
