"Initially, he responded within the hour when I posted my request then he came to the house. From there on, in terms of your appointments, there was a back and forth. I was very determined to encourage him. But he had me waited for an hour and it was disrespectful for me. I thanked him when the appointment is kept being cancelled to contact the electric company. He wanted me to do it, he finally did it and then they rescheduled. But now, from this point on where is additional work, that their company wishes the company is requiring. I cannot get the information, the specific information as to what is needed.. And this is now going on over two weeks, everything is a standstill. He is not responding and writing in a text.

"Initially, working with Universe went very well when we replaced a central air unit and installed a single-head and triple-head ductless unit... for about 1 season. After that, numerous issues arose (under warranty) from full line-replacement on the ductless units to having to come back to repair a wired connection that was reversed. This caused the AC to not work and have lots of moisture leak through our units. Additionally, pretty much EVERY season we have had an issue with our "brand new efficient systems" not working or failing. We leveraged the warranty and figured all the "kinks" of the installation were worked out over the first few years. Now, with the warranty expired for a year, we have had to have them back to our house several times with a service charge with absolutely zero consideration for the large project we have done with them and our dedicated customer history. We paid for those, thinking we would be done with repairs, as the tech said... Two days ago, with one single-head unit not powering up, they wanted to charge $285 just to show up to take a look at the issue... couldn't even send someone over when convenient to take a quick look... Severely disappointed in this "family business" that treats loyal/dedicated customers as a number. Their installation of ductless systems seems mediocre at best."

"I used stone to upgrade the electric in my house and connect my hot tub and pool. The crew that came to my home were good... But if you have a question about something Sean is nowhere to be found. You have to go thru the secretary who is absolutely clueless to ask a question. The only time you see Sean is when he comes to your house for the estimate. After that he is unobtainable. When you call in the morning with a question your lucky if you get an answer by the end of the day or the next day. I found them to be overpriced, rude and even nasty at times. I would never use them again"

Gen Ready, Inc., was established in 1979 to service the surrounding area and provide residents with all their standby electric power solutions. Our staff of knowledgeable and dedicated professionals take pride in providing outstanding, personalized service to our customers and our community. All of our techs are factory trained and certified for warranty repair and maintenance. Call us today and become one of our many satisfied customers. You can visit us online at www.getgenready.com

"After getting several quotes, last year we hired GenReady to install a house generator. Ed, the owner of the company impressed us from the start. He was knowledgeable and patiently explained the process as well as answering our questions. We knew right away that GenReady was the company for us. Lindsay kept us up to date as we moved along in the process. Our generator was installed last July. Andrew and his team installed the generator with expertise and efficiency. They took care to leave our house and yard spotless. Lindsay and Andrew were always happy to answer my questions and address me concerns. We’ve needed the generator only once (thank goodness) when our power went out due to a necessary power line repair after a car crashed into a utility pole on our street. When the power went out, our generator turned on within seconds. Our house was up and running for the four hours the line repair took, and if it weren’t for the blink of lights, we never would have known our generator was running. Every other week, our generator self tests for a few minutes giving us peace mind that it will be here for us if and when we need it. Just like the generator, GenReady is a company that runs efficiently and seamlessly. Just today, Lindsay called to tell me someone would be coming tomorrow to change the oil which reminded me that I am long overdue in submitting this well deserved rave review. Thank you to the entire GenReady team (and to Great White Propane) for all you’ve done to help us know we can weather any power outage."

Generator Install questions, answered by experts

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

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.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.
