Generator Installation Near Me

Installing a whole house generator is a task that involves several key steps, ensuring optimal performance and adherence to local codes. Understanding the process can make the decision to install a generator less daunting.

Steps involved in whole house generator installation:

  1. Site Assessment: Determining the best location for the generator, away from windows and doors to prevent carbon monoxide poisoning.
  2. Choosing the Right Size: Calculating your power needs to select a generator that can handle your home’s load.
  3. Installation: Setting up a concrete pad, installing the fuel source, whether it be natural gas or liquid propane, and connecting the generator to your home’s electrical system.

Permits and regulations to consider:

Before proceeding with the installation, it is necessary to acquire permits that comply with local zoning and building codes. Additionally, there should be an understanding of National Electrical Code (NEC) requirements, which will influence the installation process.

Benefits of Choosing a Professional Service

While some homeowners might consider installing a generator themselves, there are distinct benefits to hiring a professional service.

  • Expertise and experience: Professional installers are well-versed in local codes and manufacturer guidelines, ensuring a safe and compliant installation.
  • Proper sizing and load management: They will accurately calculate your home’s energy needs to choose the correct generator size, avoiding over or under-sizing.
  • Warranty and ongoing support: Professional services often offer warranties and maintenance plans to keep your generator in top condition.

Maintenance Tips for Whole House Generators Installation

Routine maintenance is key to longevity and reliability. Here are tips to keep your whole house generator running smoothly:

  • Regular inspections and servicing: Schedule annual check-ups with certified technicians to address potential issues before they become major problems.
  • Battery maintenance: Ensure the battery is charged and free of corrosion.
  • Fuel management: Regularly check fuel levels and the condition of fuel to ensure your generator is ready when you need it.

Generator General Questions

1. What does the term "Hybrid" or "Dual Fuel" mean?

The terms "Hybrid" and "Dual Fuel" on our generators are describing our generators ability to run on both propane or gasoline.

2. What is the THD for our generators?

DuroMax portable generators will output an industry standard total harmonic distortion (THD) rating of about 12%-20% depending on load applied. They will produce a sine wave, not a modified or square wave. This is perfectly acceptable for running common commodities found in your home such as TVs, computers, your appliances, etc.

THD is a measure of the deviation of a sine wave from a "perfect" sine wave. All electricity, including power company electricity, has measurable THD.

If you have a specific item that requires less than 5% THD such as a UPS style battery backup, a pellet stove, or high efficiency furnace control board, we recommend purchasing a DuroMax Inverter Generator that provides a less than 5% THD.

Please consult your specific appliance manufacturer to determine if the appliance requires low THD (less than 5%) to operate properly.

3. What is the difference between the DX and HX series?

Both Series feature DuroMax CO Alert, but the warranty and panel features vary by model. Please see the product specifications for the specific models you are interested in.

4. Where are our generators made?

Our generators will be designed by our engineering team in Ontario, California, and built overseas to our specifications.

5. Do your electric start generators come with a battery?

Yes, all our electric start generator models include the 12V battery needed for the electric start.

6. Can you convert our dual fuel generators to natural gas?

DuroMax does not have natural gas conversion kits availalable. Any use of aftermarket parts will void the generator warranty.

7. Are the generators safe for sensitive electronics?

Currently only our inverter generators are safe to run sensitive electronic equipment that requires under 5% THD. Our inverter generator models will produce clean power that's safe for sensitive electronics.

8. How can I make my generator quieter?

DuroMax generators are equipped with oversized mufflers to reduce noise as much as possible. The noise generated is due to the engine and not the muffler. We don't recommend the use of any 3rd party muffler silencers to lower noise. Please note that any modifications to the existing exhaust system can void your warranty and violate emission standards.

9. Do your dual fuel generators include the propane regulator and propane hose?

Yes, all our dual fuel generators will include the propane regulators and propane hose needed for a propane tank 60 lbs or less.

10. What is an Inverter Generator?

Inverter generators output produce a pure, clean AC sine wave.  Our inverters AC measure at less than 3% THD.  That is more stable than most power companies can achieve on a mass scale.

I was able to call from my own job site with questions about electrical issues and get a super fast response. These guys are very knowledgeable in their field, as well as professional. They were able to help out with any questions I had, and get me through to the next stage so that I could continue on with my project. I would 100% recommend them to any home owner, or business that needs a reliable, fast, solution to any electrical need you may encounter.
