FAQs About Our Generator Services
Do I really need a generator for my home or business?
If you want to avoid disruptions caused by outages—especially during Colorado’s severe weather or wildfire seasons—a backup generator provides reliable power when you need it most. It protects critical systems like HVAC, refrigeration, medical devices, lighting, and business operations.
How do I know what size generator I need?
Our team will perform a load calculation and site assessment to determine the right generator size based on your specific power needs, appliances, and usage patterns.
Can you repair my existing generator—even if you didn’t install it?
Absolutely. We service and repair most major generator brands, with specialized expertise in Generac systems. Whether you purchased your unit elsewhere or inherited it with your property, we can help.
Will my generator turn on automatically during an outage?
Yes—if you choose a model with an automatic transfer switch (ATS). These systems detect power loss and activate your generator within seconds, restoring electricity without any manual input.
How often should I have my generator serviced?
Most manufacturers, including Generac, recommend at least one full service per year, along with regular start-up checks. Our team can help set up a custom maintenance schedule based on your usage.
