  • What To Ask References
    Learn from Previous Customers of Electric Generator Companies in Santa Clara County

    It’s best to choose a Diamond Certified electric generator company because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a electric generator company in Santa Clara County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified electric generator company within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your electric generator company. Keep in mind, though, that references provided to you by the electric generator company are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

    If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers in Santa Clara County in the major cities of Palo Alto, Cupertino, Gilroy, Campbell, and Morgan Hill. This will help avoid them giving you the names of only customers they know were satisfied.

    1. Did the electric generator company keep you up-to-date with the status of the project? Or did you have to call in order to get information?
    2. If you live in smaller Santa Clara County towns such as Alviso, Blossom Valley, Los Altos Hills, Mt Hamilton, New Almaden, and San Martin, did they charge extra to travel to your home?
    3. Did installation contractor clean up after completing the job?
    4. When you need a new electric generator in the future, will you consider hiring this generator company again?
    5. Would you recommend this electric generator company to your friends and family?
    6. Was the electric generator delivered on schedule?
    7. Did the electric generator company provide a written estimate of the expenses?
    8. Did the electric generator company offer you a receipt for the installed generator?
    9. Were you satisfied with the services from _(electric generator company name)_?
    10. What type of electric generator did the company install for you?

An instrument which will measures electric currents in amperes.

amperage (or amps)
The strength of  electrical current that is measured in amperes.

The part of an electric generator or a motor which consists of wire wound around an iron core.  It carries an electric current. In generators that use the direct current, the armature will rotate in a magnetic field. In generators that use alternating currents a magnetic field is rotated around the armature.

Frequently Asked Questions
FAQ About Electrical Generators

Q: Why choose a Diamond Certified electric generator company?
A: Diamond Certified helps you choose an electric generator and electrical generator provider with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only electric generator company rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified electric generator

Q: What should I store my generator?
A: It will depend on what kind of generator you have. If you want to store the generator until it is needed, a portable generator will be the best choice. On the other hand, if you need consistent back-up electricity and you don’t want to set up the generator every time, the best choice is a stationary model. Each of these will need a foundation and will have to meet the local building codes. Also they can be set to automatically turn on and off.

Q: .How will I secure my generator when I am not using it?
A: Portable generators are easy to transport – that means they are targets for theft. If you will leave the generator outside when you’re not using it, select a stationary model. While installation adds more expense, it will also ensures that the generator is secured to your property.

Q: Will the fuel that is required be easily accessible?
A: Generators will run off four different fuels: diesel, natural gas, gasoline, or propane. A stationary generator can be tied into your utility or your reservoir which would cut down on refueling; however portable ones cannot. You will find it important to consider how readily obtainable the fuel will be. You will also want to know the cost.

Q: How much power will my generator need?
A: Note all the vital systems that you want to power with the generator, which would include air conditioning, alarms, and any other systems. It’s smart to make a list of the items before you speak to a professional. A specialist can calculate how much power you need and help you select a generator that will fit your needs. Remember, a generator will require running watts (to keep it going) and starting watts ( extra energy to get it going). That will figure into the generator professional’s recommendation.

Q: What type of warranty will be included with my generator?
A: A reputable generator business will provide a warranty on the equipment that they sell. You will want to ask about any limitations on this warranty. Also ask how long the warranty lasts. It could be a “good deal” on a generator really isn’t a good deal if the generator isn’t guaranteed to last.

Q: What kind of maintenance will a generator need?
A: Generators need regular maintenance. You will want to ask a professional how to care for the generator to extend its life. You will want to learn how to add the oil and check the oil, inspect the generator visually, and troubleshoot the normal maintenance problems. You will want to find out from a professional if regular maintenance checks need scheduled.

Q: How will I decide what size electric generator I need?
A: One of the most critical aspects of the purchasing an electric generator is buying one that can handle all the power generation needs.  If your new generator can’t meet your specific needs, then it simply won’t do any good because it can put undue stress on the generator.  Determining the exact size of generator to get is often very challenging and involves a number of factors.

Q: What is an Automatic Transfer Switch?
A: An automatic transfer switch will transfer power from a standard source to a generator, an emergency power, when the standard source fails. At the time the standard source is restored back to normal power the automatic transfer switch will transfer power back to the standard source and the generator is shut down. ATS’s are frequently used in high availability settings like data centers and manufacturing plans, etc.
