Customers say: Quality work

"Carlo was great! His workmanship is professional and he was very patient and attentive to our wants. He installed pot lights in our living room that had no attic access. We had issues with vents and plumbing in the ceiling but we didn t want our drywall destroyed with channel holes so after thinking through all our limited options we came up with a perfect solution that Carlo was able to implement without having to cut open our ceiling. He was great!"

"My experience working with Carlos at Enable Electric was seemless. Carlos was extremely attentive with communication, on time for visits and completed my electrical panel swap successfully. I highly recommend Enable Electric and will most definitely be hiring them again for additional projects in the very near future!"

"Although at this point the work hasn't started, this project had a lot of obstacles. The owner made multiple visits and we spoke several times to help figure out a way to reach goals without charge. He was very generous with his time and helped to figure the most cost effective way to get started and progress. He listens and goes beyond the call of duty. I have no doubts that he is true to his word and integrity. I am happy to have found such an exceptional and attentive electrical contractor. He's my guy from now on."

Generator Install questions, answered by experts

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.
