Our Generator Services in Denver Metro & Northern Colorado

Allen Service provides generator installation, replacement and repair throughout Denver Metro and Northern Colorado. Our generator installers help homeowners choose equipment based on home size, power needs, existing fuel sources and whether the goal is to keep only essential circuits running or provide broader whole-home backup power.

Generator Installation

A standby generator can automatically provide backup power when an outage occurs. Allen Service handles generator installation from initial power-load evaluation through site preparation, transfer switch connections, wiring and related electrical work. Our team can also help homeowners navigate required permits and approvals for the installation.

Generator Replacement

Older generators may eventually become unreliable, undersized for current household demand or too costly to keep repairing. Allen Service can evaluate your existing setup and recommend a replacement generator suited to the appliances, systems and circuits you want available during an outage.

Generator Repair

A backup generator is only useful when it starts and operates properly during an outage. Allen Service provides generator repair for systems experiencing starting problems, inconsistent operation, unusual noises or other performance issues. Our technicians also service generator components as needed to help restore dependable backup power.

Generator Installation & Repair in Denver Metro & Northern Colorado

Power outages can interrupt heating, cooling, refrigeration, lighting and other essential systems throughout a home. Allen Service’s generator installers serve Adams County, Larimer County and surrounding communities with professional installation and repair services designed to keep critical equipment available when utility power goes down. Our team has provided electrical and home services in Colorado for more than 60 years and can help select a generator based on the specific demands of your property.

Types of Backup Generators

Backup generators vary by size, fuel source and how much of the home they are designed to power. Allen Service can help determine which configuration fits your household and electrical system.

Whole-Home Standby Generators

Permanently installed systems designed to provide backup power automatically when an outage is detected.

Essential-Circuit Standby Generators

Systems sized to keep selected circuits and critical equipment operating rather than powering the entire home.

Natural Gas Generators

Standby generators connected to an available natural gas supply for continuous fuel access during an outage.

Propane Generators

Backup systems powered by stored propane, offering another option where natural gas service is unavailable or unsuitable.

What Kind of Generator Do I Need for My Home?

The right generator depends on more than square footage alone. Allen Service considers your home’s electrical demand, major appliances, fuel availability and whether you want essential circuits or most of the home backed up. A professional load assessment provides a more accurate recommendation than choosing a generator based only on home size.
