"Miller's Electrical quoted us about 1/3 the price of another local electrician to install a new breaker and a NEMA 14-50 outlet for an EV charger. Very impressed with their work and the guy who came out to do the installation was friendly and knowledgeable. If you want quality work at a fair price I highly recommend Miller's."

"We needed to upgrade the electrical in our mobile home and add power to our garage/shop. I called ASE and spoke to Art. He was able to come out that day and give a bid. Also met me at my son's house later that day to check out an electrical issue. Bids were very acceptable and work was scheduled. Work at my son's was done a couple days later. I requested a later date due to prep work and 2 electricians arrived right on time. I had all new receptacles installed, ran 3 new circuits (AC, extra hot water tank and split a previous circuit), wiring ran for new ceiling lights, rerouting old wiring and neatening wires from a wall removal. Our little garage/shop had only 1 available receptacle for everything (freezer, lights, etc). Now we have 16 receptacles for 110 and a drop cord for 220. We are so happy! Equipment that has been sitting for years can now be used and no more blowing a breaker if too many amps are used. In the house I can plug in the vacuum without having to crawl under the table or move something to get to a receptacle. Art, Jerron and Hayden were great to work with. They all listened to us, made suggestions and accomplished everything we needed. Highly recommend!!!!!"

"Prairie View Electric is an A+ business. I did a major remodel and addition which required dealing with old electrical wires going/coming from who knows where, installing electrical both inside and outside the home and added an RV hook up. Dustin was quick, he's a clear communicator and took the time to understand my needs and explain when something needed adjusted instead of just making assumptions. I highly recommend his company and will definitely use them again in the future!"

"I recently had a generator installed by Emerge Electrical, and I couldn’t be more impressed with the service I received from start to finish. From the initial consultation to the final installation, the team demonstrated professionalism, expertise, and a genuine commitment to customer satisfaction. The technicians arrived promptly and took the time to explain the entire process to me, answering all my questions about generator size, maintenance, and functionality. They worked efficiently and carefully, ensuring that the installation was seamless and met all safety standards. The team also took great care to keep my home clean, laying down protective covers and cleaning up after themselves. What really stood out to me was their attention to detail. They made sure the generator was properly tested and walked me through how to operate it, providing useful tips for maintenance and troubleshooting. The generator itself has been running smoothly ever since, giving me peace of mind during power outages. I highly recommend Emerge Electrical for anyone in need of electrical services or generator installation. Their professionalism, expertise, and exceptional customer service set them apart from others in the industry. They’ve earned my trust, and I won’t hesitate to call them for any future electrical needs."

Generator Install FAQs, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

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.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
