Generator Installation in Denver, CO

A sudden power outage can bring your home to a halt. The furnace shuts off, the lights and electronics go dark, and your refrigerator begins to get warm. At Pasterkamp Heating & Air Conditioning, we help you stay ahead of outages with generator installation in Denver, CO.

A reliable generator keeps your family safe and comfortable during a power outage. Our licensed electricians guide you through every step of a home generator installation. We help you choose the right unit and test it in your home before we leave.

To keep your home running during the next blackout, contact Pasterkamp Heating & Air Conditioning to learn how generator installation in Denver can give you peace of mind.

Reliable Backup Power for Your Home

Power outages can happen anytime. A spring snowstorm might bring down power lines one night, and a summer thunderstorm could leave you without electricity the next day. With a standby generator, you’re always prepared.

A standby generator is a permanent unit placed on a pad outside your home. It connects to your electrical system and runs on natural gas or propane.

These systems are unique because they work automatically. A transfer switch constantly monitors your home’s power. If it senses an outage, it starts the generator and switches your home to backup power within seconds. When utility power returns, the switch reconnects your home and shuts off the generator.

After a backup generator installation, your household is protected in several ways:
  • Maintains warmth during winter outages
  • Protects food in your refrigerator
  • Keeps your home office connected
  • Powers essential medical equipment
  • Supports home security systems

Whole-Home Standby Generator Installation

A whole-home standby generator installation makes your home more comfortable and secure. We guide you through every step of the whole-house generator installation and keep you updated from start to finish.

We start each standby generator installation project with a visit to your home. Our electrician inspects your electrical panel and wiring, then identifies the safest and most practical spot for your new generator. We discuss which appliances and systems you want to use during an outage. Then, we do a detailed load calculation to find the best capacity for your home.

Next, we set your generator on a level pad, ensuring it has enough clearance from windows and doors. The transfer switch is the main part of an automatic system.

Then we connect the generator to your fuel supply, and our electricians wire it to the transfer switch. Before we complete the whole-house generator installation, we’ll test it to make sure your generator starts and works properly.

Finally, we show you how your new system works, including its automatic features and what to expect from the control panel.

Prepare Your Home for the Next Power Outage

At Pasterkamp Heating & Air Conditioning, we take pride in helping local families stay safe and comfortable. As a family-owned local company, we treat every customer like family and care for every home. When you choose us for generator installation in Denver, you get licensed electricians who deliver quality work that lasts.

We keep our services affordable and are committed to your satisfaction. With financing options on approved credit, you can fit your home generator installation into your budget. We also install backup generators for businesses that need to stay open during outages.

Take the first step toward reliable backup power for your home. Schedule your generator installation in Denver with Pasterkamp Heating & Air Conditioning today!

Frequently Asked Questions

Scheduling a backup generator installation is a big decision, and it’s normal to have questions. We’ve answered some of the most common ones below.

What size generator do I need for my home?
The right size depends on your home’s size and which systems you want to use during an outage. Large equipment like central air conditioning needs more power to start.
Can a standby generator power my entire house?
Yes, a properly sized standby generator can power your whole home. With whole-house generator installation, the transfer switch sends backup power to every circuit in your panel.
Does a standby generator turn on automatically?
Yes, a standby generator turns on automatically when the power goes out. The transfer switch senses the outage and switches your home to generator power in seconds. After installation, the system works whether you’re home or away.
How long does generator installation take?
Most home generator installations take one to two days. The full timeline depends on permits and equipment availability. We give you a clear schedule for your backup generator installation during our first visit.

“I would choose them again and again.”

Pasterkamp has installed heating and air conditioning systems in two of our Colorado homes. In both cases, the systems have worked flawlessly. This company is a Colorado institution. I would choose them again and again.

“James really worked hard to find a solution and I really appreciate his efforts.”

Both Teresa when I called to set up service, and James who came out to check our unit were very polite and friendly. James really worked hard to find a solution and I really appreciate his efforts. We finally got our AC working. I would very much recommend these guys. Thanks much.

“I was happy to speak to someone who really knows the products and tells you what you need and didn’t try to upsell me.”

Brandon was very easy to speak to, he told me exactly what will happen and when. I have already given my sister Pasterkamp's number! I was happy to speak to someone who really knows the products and tells you what you need and didn't try to upsell me. I will always use Pasterkamp from now on!! I am getting a furnace that's the right size for my house and a heat pump installed
