Why It Matters
Not every electrician
is a Generac
Authorized Dealer.
Generac certifies a limited number of dealers in each region. The certification is not a marketing badge. It is the difference between a generator that runs reliably for fifteen years and one that voids its warranty after the first repair attempt.
The Electricians is a factory-authorized Generac dealer serving the Denver metro. Every install, every maintenance visit, and every repair we complete keeps your Generac warranty fully intact. Our team of licensed Denver electricians handles permits, transfer switch wiring, and city inspections in the same scope.

Generac Standby Generator Lineup
Generac Standby Generators: Guardian and Protector Series
The Electricians installs and services every current Generac residential standby generator throughout Denver metro. The right model depends on your home size, fuel availability, and whether you want essential-circuit backup or whole-home protection. Guardian Series covers most Denver homes from 10kW to 26kW. Protector Series handles estates and commercial properties from 32kW and up.
Generac Guardian Series
Air-cooled standby · 10kW – 26kW
Generac’s flagship residential standby generator line and the most common choice for Denver homes. Available in 10kW, 14kW, 18kW, 22kW, 24kW, and 26kW models with optional whole-house transfer switches. Quiet-Test mode runs the weekly self-test at low RPM. Mobile Link WiFi monitoring or built-in cellular variants available on most models.
Generac Protector Series
Liquid-cooled standby · 32kW – 150kW
Heavy-duty liquid-cooled standby for whole-home and light commercial backup. Available in 32kW, 40kW, 48kW, 60kW, 80kW, 100kW, 130kW, and 150kW gaseous models. The liquid-cooled engine handles continuous high loads better than air-cooled units and is the right call for estates with multi-zone HVAC, finished basements, pools, or electric vehicle charging.

What is a Generac Authorized Dealer?
A Generac Authorized Dealer is an electrical contractor certified by Generac to install, maintain, and repair Generac standby generators. Authorized status requires completed factory training on every standby product line, ongoing recertification, and direct access to Generac diagnostic tools and OEM parts that non-authorized technicians cannot use. The Electricians is a factory-authorized Generac standby generator dealer in Denver serving Centennial, Highlands Ranch, Aurora, Littleton, and the entire Front Range.
Why Denver Homes Need a Generac Standby Generator
Colorado homeowners face more power outage hours per year than most of the country. Heavy snow on aging power lines, high-wind events along the Front Range, wildfire-related public safety power shutoffs, and grid stress during extreme cold all contribute. A Generac standby generator monitors utility power 24 hours a day and automatically takes over within seconds when the grid fails. Learn more about whole-home backup power options for your Denver home.
Denver homeowners increasingly install Generac standby generators for three reasons. First, well pumps, sump pumps, and furnace blowers all stop working during outages, creating expensive secondary damage. Second, modern homes carry far more electronics, smart appliances, and refrigerated medication than ten years ago. Third, work-from-home routines have made multi-hour outages a real income problem rather than an inconvenience.
How to Choose the Right Generac Standby Generator Size
Generac standby generator sizing depends on three factors: home square footage, the appliances you want to keep running, and whether you want whole-home backup or essential-circuits only. A 14kW or 18kW Guardian unit covers most three-bedroom homes with central air conditioning. Larger homes with multi-zone HVAC, electric ranges, or finished basements typically need 22kW or higher. Estates above 5,000 square feet or homes with electric vehicle charging often call for a liquid-cooled Protector series unit.
Our in-home assessment includes a full load calculation. Our licensed Denver electricians measure your panel, identify which circuits you want backed up, and recommend the smallest Generac unit that meets the requirement. Oversizing a generator costs more upfront and burns more fuel during use. Undersizing causes nuisance shutdowns under peak load. If your existing panel is undersized for a Generac install, we also handle electrical panel upgrades and transfer switch wiring in the same scope.
Generac Annual Maintenance: What and When
Generac specifies annual maintenance to keep the 5-year limited warranty active. Skipping the service interval is the most common reason a covered repair gets denied at warranty claim time. Our annual maintenance plans follow the factory-spec checklist for each product line.
Maintenance That Keeps Your Warranty Active:
Common Generac Repair Issues
How long does Generac repair take?
Most Generac generator repairs are completed the same day. The Electricians stocks common Generac parts at our Denver warehouse, including control boards, batteries, ATS relays, and voltage regulators. For complex faults requiring special-order components, repairs typically complete within 3 to 5 business days. For urgent power outage situations, our 24-hour emergency electricians respond throughout Denver metro.
Most Generac repair calls fall into a small handful of categories. A weak or dead battery is the leading cause of will-not-start complaints, followed by stale fuel in propane-fed units that sit between outages. Failed weekly self-exercise cycles often point to controller faults that need firmware updates only an authorized dealer can apply. Transfer switch failures and voltage regulator problems are less common but more urgent because they affect the entire transfer-of-power cycle.
Authorized Dealer vs General Handyman
Generac certifies a limited number of dealers in each region for a reason. Factory-authorized status requires completed training on every product line, ongoing recertification, and direct access to the Generac dealer portal for parts, firmware, and diagnostic tools that non-authorized technicians cannot purchase or use.
Using a non-authorized electrician for Generac service is the fastest way to void your warranty on a covered repair. Generac requires authorized-dealer-completed service records to honor the 5-year limited warranty. The Electricians maintains every service record digitally and provides documentation to Generac directly on warranty claims.

Generac Generator FAQs for Denver Homeowners
Both are excellent generators, but for most Colorado homeowners, Generac is the stronger choice — and it’s the brand The Electricians is certified to install and service.
Generac advantages:
- Largest dealer and service network in Colorado — parts and technicians are readily available
- Runs a weekly self-test automatically so you know it’s ready before an outage hits
- Mobile Link app lets you monitor status remotely
- Generac’s 22kW is purpose-built for whole home coverage and is the most-installed unit in the Denver market
- 5-year limited warranty with authorized dealer installation
Kohler advantages:
- Marginally quieter operation
- Strong build quality with a loyal following
- Better option if aesthetics are a priority — Kohler units have a more finished exterior appearance
Most whole home generator installations are completed in one day — typically 6 to 8 hours for a standard installation. However, the full timeline from quote to running generator is usually 1 to 3 weeks, broken down as follows:
- Day 1: Free in-home estimate and load calculation
- Days 2–5: Permit application submitted to your municipality
- Days 5–14: Permit approval (varies by city — Denver and Centennial are typically faster than some suburban jurisdictions)
- Installation day: Generator placement, transfer switch installation, wiring, gas line connection, and testing — completed in a single visit
If your home requires a panel upgrade or a new gas line, add 1–2 additional days of work. The Electricians handles the permit process entirely — you don’t need to make a single call to the city. We schedule installation as soon as permits are approved and confirm the day before with a 2-hour arrival window.
Xcel Energy does not currently offer a direct rebate on generator units themselves, but as an Xcel Energy Trade Partner, The Electricians can help you access related incentive programs that reduce the overall cost of your installation. This includes rebates on qualifying electrical panel upgrades often required as part of a generator installation, and energy efficiency incentives tied to certain generator configurations. Additionally, a whole home generator can qualify for federal tax incentives when paired with solar or battery storage systems. Rules and availability change — contact us for a current breakdown of what incentives apply to your specific project before you purchase.
The right generator size depends on what you want to power during an outage. Here’s a simple guide for Colorado homes:
- 10–14kW — Powers essentials: lights, refrigerator, furnace, outlets, and a few appliances. Best for smaller homes under 1,500 sq ft.
- 18–22kW — Powers your entire home including central AC, well pump, and multiple appliances simultaneously. The most popular choice for 1,500–3,000 sq ft homes in Denver.
- 24–36kW — Large homes over 3,000 sq ft, homes with electric vehicle chargers, or properties with high electrical demand.
A licensed electrician will perform a load calculation during your estimate to determine the exact right size for your home. Oversizing wastes money; undersizing means the generator trips during heavy use. The Electricians recommends Generac’s 22kW unit for most Denver-area homes — it handles Colorado winters including furnaces, sump pumps, and refrigeration without strain.
Yes. A properly installed and well-documented generator can increase resale value and is a major selling point for Colorado buyers.
Standby generators are permanently installed and start automatically, while portable units require manual setup and operation.
A whole home generator in Colorado typically costs between $8,500 and $18,000 installed, depending on the size of your home, the brand, and whether a panel upgrade or gas line extension is required. A 22kW Generac — the most common size for a 2,000–3,000 sq ft home — runs approximately $10,000–$13,000 fully installed with permits. Larger homes or those needing electrical panel work will fall toward the higher end. That price includes the generator unit, transfer switch, wiring, concrete pad, permits, and inspection. Xcel Energy customers may qualify for rebates that reduce the net cost further. The Electricians provides free in-home quotes with upfront pricing — no surprises on installation day.
Most standby generators need annual maintenance, but units used more frequently may require service every six months.
