Chester County, PA Backup Power Generators Installation & Maintenance Plans

Adding a commercial generator to your property or business can give you peace of mind that even in a power outage, your business will be safe from electrical failure or issues.

What to know about commercial and whole house generator installation

As a leading provider of generator services in West Chester, PA, we know the value our commercial customers get from adding a standby generator or backup generator to their businesses.

If you are considering adding a new generator to your business, here are some frequently asked questions you might have.

A certified technician should complete every generator installation to ensure all electrical connections are correctly made and everything is safely installed. Our certified technicians take pride in their job and ensure service and maintenance is completed quickly, and accurately.

It can be beneficial to run a test for your generator with and without a load at least monthly to keep the system lubricated and confirm there are no issues with the chillers, motors or transfer switch.

It is recommended that most generators are installed outside, at least 20 feet away from your house or business. This ensures that any fumes from the generator are directed far away from your building to keep everyone safe.

For large commercial buildings, there are a few different types of generators we recommend:

Diesel generators

This option is highly fuel efficient and has overall low noise levels to prevent disruption. Diesel is also safer since it is less flammable than other options.

Natural Gas generators

If you are looking for a reliable and trusted emergency backup power source, installing a natural gas generator could be a great fit for your business.

While they are less expensive, they are not as fuel efficient as diesel, which can result in higher operating costs depending on fuel cost.

Liquid propane generators

With low emissions, many people prefer the long shelf life of propane. But, maintenance on a propane generator requires regular service by certified technicians. No matter what you are looking for, our skilled technicians can help you install the backup generator that best fits your business needs and budget. We offer generator installation for various brands and styles, ensuring you have peace of mind when the electricity goes out in West Chester.

A standby generator is wired directly into your business’s power grid and equipped with a fuel tank that will kick in when the power goes out. Once the electricity goes during power outages, your commercial generator will turn on and begin providing power to your building.

If you are looking for a commercial or residential generator installation West Chester PA, call Callaghan before a power outage.

Whether you need to install a backup generator for your business or a whole house generator repair, our team is there to help you with your backup power needs. Next time power outages hit our area, do not lose power — keep the lights on with a backup power source.

Call us to learn about our generator installation service, including maintenance plans, to ensure you are not impacted by a power loss that impacts your business.
