Generator FAQs
How much does it cost to install a home backup generator?
Generator installation cost would start at about $10,000 for a basic installation if the gas and electric meter are right next to each other and the generator is going near that locaiton for a 16 circuit switch with a 10KW generator. Cost will rise with the generator size and installation options. Typical 20 KW installation with a whole house transfer switch with the gas and electric meter in the same location would be aobut $13,000.
How long will it take to install a home backup generator?
A typical installation of a whole house generator and transfer switch will take one day (two techs eight hours) if the gas and electric meter are located near the generator.
How do I check or measure my generator's oil level?
With the generator in the off position (not running) pull the dipstick to make sure the level is correct. There should be a line on the dipstick showing the full mark.
How do I fill my generator oil?
On most air cooled units there is a fill cap on top of the valve cover. Most air cooled units take 5W 30 full synthetic oil.
What does the error or fault code on my generator need?
Usually this means something is wrong and the unit will not start or produce voltage. So the unit will not work during a power outage.
What are some things I can check if I have partial power out and the generator is not running?
Check for fault codes in the generator. If the generator is in fault try to reset the fault by turning the unit to off and putting it back in auto. The unit might start, if the unit fails to start, you will need a technician to come out to further troubleshoot the unit.
What if I referred someone to CRG Electric?
Currently if you have purchased a generator from CRG Electric we will give you a $100 referral fee. Kohler will also match the $100 referral fee, depending on if they are running this promotion. There is paper work that is needed to be filled out to receive both. Feel free to call our office for the paperwork.
Do I need a gas meter upgrade with my generator installation?
How often do I need a PMA on the generator?
Do I need a load bank every year on my generator?
While a load bank isn’t always required, it can be highly beneficial—especially if your generator hasn’t been used during a real power outage. A load bank applies a controlled electrical load to the unit, allowing it to run under realistic operating conditions. This helps identify any potential issues and ensures the generator is performing as expected when you actually need it.
For systems that haven’t been exercised under load, we recommend performing a load bank test during routine maintenance to confirm reliability and prevent unexpected failures.
How often should I check the oil on my generator during a power outage?
Alway refer back to the manual for recommendations. We recommend every 8 hours in long run periods.
How long will my generator last?
This all depends on how well the generator is maintained and the manufacture. I would say the unit’s life expectancy is approximately 15- 20 years.
Will my generator sense a brown out?
The Kohler units will sense low voltage situations (dimming lights) and transfer the home to generator power.
How much does it cost for yearly maintenance?
One trip a year for an air cooled 8-24KW is $340. It is best to give the office a call to confirm pricing.
How often does my battery need to be changed in my generator?
We strongly advise the battery to be swapped out every three years. Even if the battery tests good we see lots of battery failures after they are three years old.
Can I sign a continuous maintenance contract so I do not have to sign a new one every year?
We offer a continuous maintenance contract so a contract does not need to be signed every year. If the contract is canceled we need to have this in writing.
Why do I need a maintenance contract?
How long will I be without power during a generator installation?
A typical installation there would be about a three hour power outage during the installation of the transfer switch.
How long will I be without power during a generator installation?
A typical installation there would be about a three hour power outage during the installation of the transfer switch.
How long will a typical generator installation take?
A typical generator and transfer switch installation will take one day with two technicians from start to finish. When the generator is located farther away from the gas and electric meter the time of the installation would increase.
