We understand that you need to be able to depend on your backup power system to work when you need it, and we can help. Just listen to what a few of our happy customers had to say about us:

“…on a very cold night I found the block heater for one of my generators not working - this generator backs up our data center (and) at the time we were in the quarterly black out and needed 100% insurance the generator would start if needed. This caused me to spend the night at work starting the generator every two hours. I called Colorado Standby and they had one installed and working in 90 minutes plus another one for back up ordered overnight. I had Colorado Standby give me quote for maintain our four generators and had it signed in two days. Every time I call I have never waited more than 1 hour for someone to arrive onsite no matter how small or big the issue is they handle it that day. I fired our other generator service company and have never regretted it.”

“I have been impressed with the quality of work and commitment to services provided by all the great people at Colorado Standby! Every time I have a question or concern about a piece of equipment that Colorado Standby has serviced, they have been able to clearly communicate the problem and fit Quasar into their schedule. I am truly appreciative of their services and friendly employees!”
