Generator Service in Denver

Keep Power On When Colorado Winds Take It Down

High winds and severe weather can lead utilities in Colorado to shut off electricity with little warning. If you work from home, rely on medical equipment, or simply want to keep your household safe and comfortable, reliable backup power is not a luxury, it is a safeguard. At Allen Service, we provide generator service in Denver for homes and businesses that want dependable power when the grid goes quiet.

Our family has served the area since 1962, and electrical safety has been part of that story from the beginning. We install, maintain, and repair backup generators as part of our broader heating, cooling, plumbing, and electrical services, so your systems work together to protect your property. With 24/7 emergency response and same-day service when possible, our goal is to be there when you need help most.

Have questions about generators for your property:

  • Talk with our team about backup options for medical or work needs.
  • Learn how whole-home and portable systems can support your daily life.
  • Find out what an in-home generator assessment includes.

Reliable Backup Power for Colorado Homes & Businesses

Power shutoffs related to wind and fire danger have become more common, and a brief outage can quickly turn into a serious issue. Refrigerators warm up, medical devices lose power, and home offices grind to a halt. We design generator solutions that help you stay prepared, whether you need to protect one critical circuit or keep your whole building operating.

Many of our customers contact us after living through one stressful outage. Some care for family members who use oxygen or other powered medical devices. Others run their business from a home office and cannot afford to lose connectivity during a workday. In each case, we listen to what matters most, then recommend a backup generator approach that fits those priorities.

Because we are a full-service electrical provider with decades of experience, we understand how generators interact with panels, HVAC equipment, and other systems in your space. Our technicians follow current safety codes and manufacturer guidelines, and each visit is supported by our customer-first guarantee. That means clear communication, respectful treatment of your property, and work that is done the right way the first time.

Whole-Home & Portable Generator Options

Every property has different electrical needs, so we offer several ways to add backup power. Some customers want full coverage during outages, while others focus on a few essential circuits. Our team explains the options in plain language, then helps you decide what makes sense for your situation and budget.

For whole-home systems, we work with Generac units that are designed to power most or all of a typical residence when an outage occurs. These systems are connected to your electrical panel through an automatic transfer switch, so they can start and move power over when the utility supply drops. We size the equipment based on your panel capacity, expected load, and priorities, such as running your furnace, air conditioning, refrigeration, and critical outlets.

Some homeowners and business owners already own a portable generator or a standby unit from another brand. We can often support those setups by installing transfer switches and making safe connections:

  • Reviewing the generator type and output to see what it can safely support.
  • Installing transfer equipment to avoid backfeeding and unsafe extension cord use.
  • Checking wiring and grounding to match electrical codes.

Where natural gas service is available, we can discuss that fuel source. In other cases, propane may be a better fit. Our goal is to configure a safe, practical system that aligns with your property and how you live or work.

How Our Generator Installation Process Works

A clear process can take much of the stress out of planning backup power. We follow a consistent set of steps for generator installations so you know what will happen, who will be on site, and how long the work is likely to take. Each phase is handled by trained technicians who focus on safety, code compliance, and respect for your home or business.

Here is how we typically approach a new generator installation:

  1. Initial assessment. We visit your property to review your electrical panel, discuss which systems you want to support, and look at potential generator locations outside the building.
  2. Load planning and recommendations. Our team calculates approximate loads for heating and cooling, refrigeration, lighting, medical equipment, and other circuits. We then explain different ways to cover those loads, from essential-only setups to broader whole-home coverage.
  3. Fuel and placement planning. We review options for natural gas or propane connections and identify a location that meets clearance, ventilation, and local code requirements. When permits are required, we work through those steps as part of the project.
  4. Installation day. On the scheduled day, our technicians arrive in uniform, protect work areas, set the generator pad or mounting surface, place the unit, and complete the wiring between the generator, transfer switch, and your panel.
  5. Testing and walkthrough. After installation, we run tests to confirm proper operation and verify that circuits transfer correctly. We also walk you through basic controls so you know what to expect when the utility power goes out.

Throughout the project, our fully stocked trucks help us handle most tasks without repeated trips for materials. Every connection is completed in line with applicable electrical codes and manufacturer guidance, and our team cleans up the work area before leaving. If you have questions at any point, we take time to answer them so you are comfortable with how your new backup system works.

Generator Maintenance & Repair Services

Once a generator is installed, regular care is what keeps it ready for the next outage. Like a furnace or air conditioner, a standby generator has moving parts, filters, and controls that benefit from periodic inspection and service. We offer maintenance and repair services to help your system start and run when you need it most.

Our generator maintenance visits can include:

  • Visual inspections for damage, corrosion, or loose connections
  • Oil and filter changes based on manufacturer recommendations
  • Battery testing and replacement when needed
  • Check of fuel supply lines and valves
  • Test runs to confirm automatic start and transfer operation

When something is not working correctly, we provide troubleshooting and repair for many common issues. These can include no-start conditions, shutdowns during operation, transfer switches that fail to move power correctly, fuel supply concerns, or alerts from sensors and control panels. Our electricians arrive prepared with diagnostic tools and commonly used parts, and same-day service is often available for urgent power concerns.

Many customers include generator checks within our Membership Rewards Program. During scheduled system visits, our technicians can review generator operation along with other key equipment, which supports reliable performance throughout the year. If we find an issue, we explain your options clearly before any repair work begins.

Benefits of Installing a Backup Generator

A well planned generator can support much more than a few lights. For many households and businesses, it acts as a safety measure and a way to keep daily life moving during an outage. We help you identify which benefits matter most, then design your system with those in mind.

Some advantages our customers value include:

  • Support for medical and safety equipment. Backup power can help keep oxygen machines, medical pumps, security systems, and other critical devices operating when utility power is cut.
  • Protection for work-from-home setups. With many people working remotely, a generator can help maintain internet service, computers, and key office equipment, so a neighborhood outage does not end your workday.
  • Comfort for your household or guests. Heating, cooling, and refrigeration are often high priorities. Backup power can help prevent food from spoiling and make it possible to stay in your home during a longer outage.
  • Reduced risk of damage. By keeping sump pumps, heaters, and certain appliances running, a generator can help reduce the chance of issues such as frozen pipes or water intrusion, especially during storms.
  • Appeal for future buyers. While every market is different, many buyers appreciate properties that already have reliable backup power installed by a known local contractor.

Because we work across electrical, HVAC, and plumbing systems, we look at the bigger picture of how power loss affects your property. That perspective helps us recommend generator configurations that support the systems you rely on most, rather than focusing only on a single circuit or appliance.

Why Homeowners Trust Allen Service With Generator Work

Choosing a company for generator installation or repair is a decision about safety and long-term reliability. Our family has operated Allen Service since 1962, and third-generation owners Jeff and Mike Allen continue to lead the business with the same focus on honesty, craftsmanship, and care for every customer. That history is one reason so many neighbors turn to us when they need generator and electrical help.

Each service visit reflects our customer-first approach. Technicians arrive in uniform, wear shoe coverings, and protect floors and work areas. They do not use tobacco on site, and they take time to answer questions in clear, straightforward language. Our goal is to respect your home or business as if it were our own, from the first knock on the door to the final cleanup.

Behind the scenes, ongoing training keeps our team current on modern electrical systems, safety codes, and generator technology.

With 24/7 emergency response for electrical issues and financing options for larger projects, we work to make reliable backup power more accessible when you decide the time is right.

Frequently Asked Questions

Do I Really Need a Backup Generator for My Home?

Some homes benefit greatly from a backup generator, while others may see it as added peace of mind. If you have family members who rely on powered medical equipment, work from home, or live in an area that experiences shutoffs during high wind or fire conditions, a generator can be especially helpful. It can support heating and cooling systems, refrigeration, lighting, and essential outlets when grid power is unavailable. During an in-home assessment, we talk through your specific situation and help you decide whether a generator fits your priorities.

Can You Work With a Generator I Already Own?

In many cases, we can work with existing generators that you already have on site. This can include portable units or standby models from other brands, as long as they are appropriate for the intended load and can be installed in a safe configuration. Our electricians can install transfer switches, evaluate wiring, and make adjustments needed to connect your unit properly to your electrical panel. If we see limitations, we explain them and discuss your options before you decide how to proceed.

How Will You Decide What Size Generator My Home Needs?

We start by reviewing how you use power during a typical day and which systems you want to protect during an outage. Our technicians look at electrical panel size, major appliances, HVAC equipment, and sensitive devices such as medical tools or computer systems. Based on that information, we calculate approximate loads and talk through different coverage levels, from essential-only to broader whole-home setups. The final recommendation balances your priorities, your panel capacity, and the practical fuel and placement options for your property.

How Often Should My Generator Be Serviced?

Service frequency depends on the type of generator, how often it runs, and manufacturer guidance. As a general pattern, many standby units benefit from at least an annual visit that includes inspection, oil changes as needed, and a test run under load. If your generator runs frequently or supports critical medical or business equipment, additional checks may be helpful. Our team can suggest a maintenance schedule based on your model and usage, and generator checks can often be included as part of our Membership Rewards Program visits.

What Happens If My Generator Will Not Start During a Storm?

If your generator fails to start during an outage, you can contact our team for help. We provide 24/7 emergency electrical support, and same-day generator repairs are often possible depending on call volume and parts needs. When we arrive, we inspect the unit, controls, transfer switch, and fuel supply to pinpoint likely causes. Our fully stocked trucks allow us to resolve many issues on the spot. If a more extensive repair or part order is required, we explain your options and next steps before any additional work.

Do You Offer Financing for Generator Installations?

Yes, we offer financing options for larger projects such as standby generator installations. Backup power can be a significant investment, so flexible payment choices can make the decision easier. During your estimate, we review pricing in detail and can outline available financing programs that may fit your budget. Our team is committed to transparent communication about costs before work begins, so you understand the financial side of your project.

Will Generator Installation Disrupt My Home?

Any electrical project brings some activity, but we work carefully to limit disruption as much as possible. Most of the work takes place outside near the installation area and by your electrical panel, and we let you know in advance when short power interruptions may be needed to complete wiring. Inside your home or business, technicians use shoe coverings and floor protection, and they clean up work areas when the job is done. We also explain the expected timeline ahead of time so you can plan around the installation day.

Benefits of Installing a Generator

A generator does more than just keep the lights on, it protects your household or business operations when every second counts. Whether you run a medical device, manage a data-driven business, or simply want to prevent spoiled food and frozen pipes, a standby generator acts as a safeguard against downtime and damage.

Other advantages of installing a generator include:

  • Automatic backup power. Your standby generator activates instantly during an outage, no need to flip a switch.
  • Protection for essential appliances. Keep refrigerators, medical devices, HVAC systems and sump pumps running.
  • Peace of mind during emergencies. Stay connected, safe and comfortable no matter the storm.
