Pueblo, CO Standby Generator Installation & Maintenance Guide
Estimated Read Time: 9 minutes
Losing power in Colorado is more than an inconvenience. It puts comfort, safety, and medical devices at risk. The fix is simple: consistent generator maintenance. In this guide, you will learn exactly how often to service your generator, what to check between visits, and how to avoid the most common failures. If you are planning an install or overdue for a checkup, you can also save with our current offer below.
Why generator maintenance matters in Colorado
Colorado’s power threats are real. Summer lightning, fall wind on Monument Hill, and heavy spring snow in Woodland Park can trigger outages without warning. A well‑maintained generator keeps your HVAC, fridge, lights, and medical devices running when the grid fails.
Two hard facts guide smart planning here:
- Most manufacturers recommend an annual professional service for residential standby units, plus a weekly exercise run of about 10 to 20 minutes to keep batteries charged and fluids circulated.
- Engines lose power at higher elevations. Naturally aspirated engines typically derate by roughly 3 percent per 1,000 feet of elevation. At 6,000 feet around Colorado Springs, that can be an 18 percent reduction. Proper sizing and load planning are critical to offset altitude.
Maintenance makes the difference between a seamless transfer and a no‑start call at 2 a.m. Our licensed electricians pair generator maintenance with surge protection and panel upgrades so the entire system works together, not just the generator.
How often should you service your generator?
The right schedule depends on fuel type, usage, and whether you have a standby or portable unit. Use this baseline, then adjust for your home and elevation.
- Standby generators
- Professional maintenance: once per year or every 200 operating hours, whichever comes first.
- Self checks: monthly visual inspection, run the weekly exercise cycle, and review the controller for alerts.
- Battery: test annually and replace every 3 to 5 years as needed.
- Portable and inverter generators
- Oil and filter: after the first 20 to 30 hours on new units, then every 50 to 100 hours, per manufacturer.
- Fuel care: use fresh fuel, add stabilizer for storage, and run the carburetor dry when storing more than 30 days.
- Seasonal tune‑ups
- Pre‑winter: confirm cold‑start performance, battery health, and fuel delivery. Natural gas pressure and propane tank levels matter more when temperatures drop.
- Pre‑summer: inspect cooling airflow and clean the cabinet. Dust and cottonwood fluff can choke a unit during extended heat waves.
These intervals keep your unit ready on the day you actually need it instead of just the day it was installed.
What a professional generator maintenance visit includes
A proper service is more than an oil change. Here is what our electricians inspect and test to keep your system reliable:
- Safety and electrical
- Transfer switch operation under load
- Tightness of lugs and terminations in the generator and panel
- Grounding and bonding verification
- Surge protection status
- Engine and fuel
- Oil, filter, air filter, and spark plugs as needed
- Fuel system checks: gas pressure for natural gas, regulator performance, propane tank level and line integrity
- Exhaust system inspection and CO safety
- Battery and starting
- Battery voltage, load test, and charger output
- Starter draw and crank time
- Controls and runtime
- Firmware and controller logs
- Weekly exercise schedule verification and clock accuracy
- Full functional test: start, transfer, run under load, and retransfer to utility
- Home integration
- Load balancing review so essential circuits keep power
- Smart panel or energy monitor integration checks
Before we leave, we commission the system, transfer power, and walk you through operation and expectations so there are no surprises during an outage.
DIY checks you can safely do between visits
You do not need to be an electrician to help your generator last longer. Use these quick checks monthly:
- Visual walk‑around
- Clear debris, snow, and vegetation from the cabinet and around the intake and exhaust.
- Look for leaks or damage.
- Controller review
- Confirm the unit shows Ready or Auto. A simple switch left in Off can cause a no‑start event.
- Fuel readiness
- Natural gas: make sure gas valves to the unit are on and accessible.
- Propane: keep tank above 50 percent in cold snaps to maintain pressure.
- Battery awareness
- Check that the charger is powered. A tripped breaker or unplugged charger is a common cause of dead batteries.
If anything looks off, schedule service before the next storm. Small issues caught early prevent costly repairs later.
Signs you need generator service now
Call for service if you notice any of the following. These are the early warnings our techs look for and the issues homeowners report most often:
- The generator fails to start
- You notice a coolant leak
- Your generator runs slower than normal
- There is visual damage to the exterior of the generator
- Battery warning lights, repeated crank attempts, or a strong fuel smell
- Transfer switch does not move power in or out during tests
"Brian did a GREAT job getting our generator back up and running. Now if we have a power outage again we are covered."
Fast attention to these symptoms protects both the generator and your home’s sensitive electronics.

Installation plus maintenance planning for long life
Planning and maintenance go hand in hand. When we install a generator, we begin with a detailed electrical inspection to make sure your system can safely support backup power. We size the generator with high‑altitude derating in mind and review which circuits matter most for your family.
Key installation elements that extend life:
- Transfer switch selection
- Manual for portable units or automatic for standby systems. Properly sized, code‑compliant, and tested during commissioning.
- Fuel choice and delivery
- Natural gas offers convenience and long runtime. Propane provides independence where gas is not available. We check line sizing and pressure so the engine runs cleanly under load.
- Electrical integration
- Panel and breaker upgrades when needed, plus surge protection to help extend appliance life. Smart panel integration gives visibility into loads so you avoid overloads during an outage.
- Commissioning and education
- Simple startup, no surprises. We test, transfer, and show you exactly what to expect when the grid drops.
Get the install right on day one, and maintenance becomes predictable and cost‑effective for years to come.
Colorado‑specific tips for better reliability
Colorado’s elevation, temperature swings, and winds create unique demands. Use these pro tips to keep your generator ready:
- Plan for altitude
- Work with a pro who derates for elevation and verifies gas pressure under load. This protects voltage stability for HVAC and medical devices.
- Winter readiness
- Keep propane tanks above 50 percent in cold weather to maintain vaporization and pressure. Cold starts stress weak batteries, so annual testing is worth it.
- Airflow matters
- In cottonwood season, clean cabinet screens and check for fluff buildup every few weeks. Blocked airflow can cause shutdowns during long summer runs.
- Exercise timing
- Set weekly exercise to a time when you can hear it and notice alerts, such as mid‑morning on weekdays. Consistency is more important than volume.
- Outage planning
- Decide which circuits you will shed during extended events. Smart panels or labeled breaker lists make it easy to prioritize HVAC and refrigeration over non‑essentials.
Follow these steps and your generator will be ready when the next lightning storm rolls over Pikes Peak.

Frequently Asked Questions
How often should a standby generator be serviced?
Most residential standby units need professional generator maintenance once a year or every 200 hours, plus weekly 10 to 20 minute exercise cycles to keep batteries healthy.
Do portable generators need annual service too?
Yes. Change oil and filters by hours run, often every 50 to 100 hours after the initial break‑in. Inspect spark plugs, air filter, and fuel system before each season.
What signs mean my generator needs service now?
Watch for no‑start attempts, coolant leaks, slow running, visible damage, warning lights, fuel smells, or a transfer switch that fails to move power during a test.
Does Colorado’s altitude affect generator performance?
Yes. Naturally aspirated engines typically lose about 3 percent power per 1,000 feet. Proper sizing, gas pressure checks, and smart load management offset the loss.
Can WireNut maintain my existing generator even if you did not install it?
In many cases, yes. We service most major brands and can inspect your transfer switch, fuel supply, and panel to confirm safe operation. Call to confirm your model.
