The Backup Generator Process

Residential backup generators work by providing power to your utilities. When your utility power fails, the generator turns on automatically and provides power by following just four simple steps:

1. Your Utility Power is Lost

When a power outage occurs, your home’s connection to the utility grid is interrupted.

2. Your Generator Detects a Problem

Backup generators are equipped with advanced sensors that automatically detect the power loss and activate the system.

3. Power is Transferred through ATS

Next, the Automatic Transfer Switch (ATS) takes control, seamlessly switching your home’s power source from the utility grid to your generator.

4. Electricity is Restored

Within seconds, your generator will start supplying electricity to your home, ensuring power until the utility power is restored.

Our Generator Installation Process

Consultation and Scheduling

Contact Stan’s Heating, Air, Plumbing & Electrical to start your generator installation process. Our dispatch team will schedule your initial consultation. Your Project Manager will assess your unique generator requirements and provide you with a proposal. If there are no unusual plumbing or electrical concerns, the proposal can generally be provided on the spot. This first step ensures a seamless process right from the start.

Detailed Planning and Permit Acquisition

Your installation team will include your Project Manager, Install Manager, Plumber, and Electrician. Before starting any work, the team will conduct a thorough on-site walkthrough. Stan’s Heating, Air, Plumbing & Electrical will also handle the necessary paperwork, including obtaining electrical and plumbing permits. A site or plot survey and an HOA approval letter may also be required at this phase.

Installation and Finalization

Once all approvals and permits have been obtained, we’ll schedule your generator installation. Your Plumber will complete the installation and coordinate the City inspection. Once approved, your Electrician will commission the generator and facilitate the closure of the permits. Weather permitting, we typically complete the installation within 4-5 days.

Ensure Longevity with Regular Generator Maintenance

Regular maintenance is crucial to keep your generator in top condition and extend its life. At Stan’s Heating, Air, Plumbing & Electrical, we offer comprehensive generator maintenance services to help you maintain peak performance. Our technicians will conduct routine inspections, perform necessary repairs, and keep your generator operating efficiently, so it’s ready to provide reliable power whenever you need it.

Frequently Asked Questions

The installation time can vary depending on the specific requirements of your home. Our team will provide an estimated timeline during the consultation process.

We offer both standby (automatic) and manual generators. Standby generators are designed to switch on automatically when the grid power is lost, while manual generators do require manual activation.

Though more expensive than manual generators, standby generators are the preferred option, especially for homeowners who are often away from home, as they guarantee electricity in the event of an outage.

To learn more, contact our team to discuss your options.

Our Generac generators can be connected to your home’s natural gas line, and can run on natural gas or liquid propane, eliminating the need for manual refueling.

If you purchase a generator with an air-cooled engine, as well as ensure it receives regular maintenance from a qualified electrician, you can expect your generator to last up to 40 years or longer.

Our Reviews

We switched from another plumbing and HVAC service to Stan's and we couldn't be more happy. Their prices are way more affordable, their personnel are much more knowledgeable, and they can get to you usually very quick - especially important if say your AC blows out in the middle of summer (which it did)! Highly recommend!

B. Parker

Aldarbert was very knowledgeable. He helped me to make the best decision for my Tesla and he installed it quickly. I was able to tested it out before he left, which worked perfectly as soon as him plug it in. I definitely recommend him and the company. Thanks!

Marva B.

Mr Robert Mendoza and Mr Daniel did an amazing Job replacing my evaporator coil which leaked with the new one. He took the time out to explain to me every detail he was doing as I asked questions. They both did a outstanding job. They made sure they put plastic down on my wooden floors as well

Larry D.

Showed up the next morning to check out the situation. Julian Rodriguez showed up later that afternoon with the new hot water heater. He explained everything he was doing during the process. Very thorough, polite & professional. Cleaned up the area he was working in and removed all the debris and old parts.

Aimee B.

“Stan’s has serviced our furnace and air conditioner for the past 15 years and was recommended by the former homeowner. They are knowledgeable and professional. As a longstanding company, the techs are prompt, friendly and trustworthy. I highly recommend them.”
