About Us

Signs You May Need Generator Replacement

Frequent Repairs: If your system requires repeated generator repair, replacement may be more cost-effective than continued service.
Inconsistent Performance: If your generator struggles to start, fails during outages, or no longer powers your home reliably, the system may be nearing the end of its useful life.
Aging Equipment: Most house generators lose efficiency and reliability as they age, especially if maintenance has been inconsistent.
Your Power Needs Have Increased: If your current system no longer supports your home’s electrical demands, upgrading to a larger whole-house generator may be necessary.

Our Generator Replacement Process

Initial Consultation

We begin with an initial consultation to evaluate your current generator system, review your home’s backup power needs, and determine whether replacement is the best long-term solution. Our team will assess your existing setup, discuss your power priorities, and recommend the right replacement system based on your home’s size and electrical demands.

Professional Removal & Installation

Our licensed electricians and skilled technicians safely disconnect and remove your old generator before installing the new one. Every replacement is installed in accordance with manufacturer specifications, local code requirements, and best practices for long-term reliability and safety.

Testing, Permits & Final Verification

We handle all necessary permits, complete startup testing, and verify that your new generator is operating properly before the job is complete. Once testing is finished, our team will walk you through system operation, answer any questions, and ensure you feel confident using your new backup power system.

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!

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.”
