"Hired them to install a lock-out kit on my circuit breaker panel, an outside outlet to connect my generator, and a power-back alarm. The owner, Chris, arrived on time to do the quote and was very clear and helpful. The installers also were prompt, did an excellent installation, simulated a power outage, and showed my how to switch the whole house over to the generator. "

"Outstanding Service from Technicians Dennis and David, Haas and Sons Electric!!! We hired Haas and Sons Electric at 8:30am on 12/15/25. They responded, scheduled and completed the work before 2PM the same day. Haas and Sons Electric addressed a wiring issue related to the doorbell / security camera. Dennis and David were exceptional! They called while enroute and arrived promptly as scheduled for the appointment. They immediately demonstrated high levels of professionalism and knowledge about our electrical issue: Dennis answered all our questions and patiently walked us through their diagnostic process. He also clearly explained the factors related to the wiring connection between the doorbell wiring by the builder (of the home) and the security camera equipment installation related to the root cause of the issue. The quality of work was superb. David replaced the doorbell system and all its necessary equipment components efficiently and ensured all new wiring was up to code, meticulously cleaning the work areas afterward. We appreciated their honest approach and made recommendations for future maintenance without any sales pressure. We are extremely satisfied with the results and will use Haas and Sons Electric for all future electrical needs. In my entire community, Haas and Sons Electric are highly recommended for their expertise, integrity, and excellent customer service."
