When the power goes out or you’re relying on a generator for work, you need it to start and run reliably. Our Denver generator repair service focuses on keeping your portable and small backup generators ready when you need them most. We provide complete tune-ups that include carburetor cleaning, fuel system flushing, oil changes, spark plug replacement, air filter service, and full engine diagnostics.
Whether your generator won’t start, only runs on choke, surges under load, or has been sitting with old fuel, we can bring it back to dependable operation. We work on popular brands like Honda, Generac, Champion, Predator, Craftsman, Briggs & Stratton, and more. Our goal is to make sure your generator is ready for outages, camping, job sites, and emergency situations across the Denver Metro area.
If your generator is hard to start, stalls when you plug something in, or hasn’t been serviced in years, it’s likely overdue for maintenance. Over time, fuel breaks down and clogs jets, oil thickens, and ignition components wear out. Our generator tune-up service in Denver includes draining stale fuel, cleaning the carburetor, changing oil, checking spark, testing voltage output, and verifying that your generator can handle load properly.
We provide honest diagnostics and will let you know whether a repair is worthwhile based on the generator’s age and condition. Most tune-ups and light repairs can be completed in just a few days, depending on parts availability. Whether you use your generator for storms, RV trips, or tools, we make sure it’s ready before you need to rely on it.
Services include mobile engine tune-ups, repairs, and blade sharpening for most small engine yard equipment. Fast, affordable, and professional — we come to you!
Generators are more than just small engines—they’re also power systems. That’s why we inspect both sides: engine performance and electrical output. Our Denver generator repair process starts with checking compression, spark, fuel delivery, and carb operation. Once the engine runs correctly, we test the alternator, voltage regulator, outlets, and load capability.
Common issues we repair include hard starting, running only on choke, low power output, hunting or surging under load, tripped breakers, non-working outlets, and fuel leaks. We verify proper RPM and voltage so your tools, appliances, and backup systems get stable power. By addressing both mechanical and electrical issues, we restore safe, reliable performance.
Colorado weather and extended storage can be brutal on generators. Many units sit for months or years with untreated fuel, leading to clogged jets, varnished carburetors, and rust in fuel tanks. Our generator maintenance service helps Denver homeowners avoid those problems by offering pre-season and post-season service. Before storm season or planned use, we can tune your generator, replace fluids, test output, and ensure everything is working correctly.
If you’ve had a “backup” generator sitting in the garage or shed that hasn’t been started in years, don’t wait for a power outage to find out it doesn’t run. We’ll inspect and service your unit so that when you pull the cord or hit electric start, it’s ready to go. Proper maintenance extends the life of your generator and protects your investment.

A generator that doesn’t start when you need it is more than just an inconvenience—it can mean spoiled food, interrupted work, or unsafe conditions. That’s why our Denver generator repair service focuses on thorough diagnostics and quality workmanship rather than band-aid fixes. We start by confirming the basics: compression, spark, and fuel. From there, we clean or rebuild the carburetor, flush old fuel, replace filters and plugs, and inspect the ignition and charging systems.
We also test your generator under load to see how it performs in real conditions. If we see voltage drops, surging, or overheating, we address the root cause before returning it to you. Our tune-up and repair options are tailored to the age and condition of your generator, and we’ll always explain what we recommend and why.
Whether you’re using a portable generator for camping, job sites, tailgating, or emergency backup, we help you keep it running safely and reliably when it matters most.
