"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

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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.
