"I left a previous review after Mike with Randy's Electric came out to look at the job I wanted completed. That went great and I stated that if I went forward with the project I would hire him. Well, I went forward with the project and could not be happier. Everything went smooth on the date of installation. After discussing the location of the plug in site Mike thought the best location would be in a spot which required him to do extra wiring but there was no change in cost. He was excellent at explaining what he was doing and answering my questions. He even took the time to test everything with the generator hooked up to the transfer switch to make sure we everything worked properly. I have more electrical projects coming up and will definitely be hiring Mike at Randy's Electric. I recommend you do too! Oh and a really great perk is that Randy's Electric offers "same as cash" financing. I applied ahead of the start date and the process was super quick and easy. That really helped out."

"My electrician Travis was amazing to work with. He didn’t mind me asking questions. He took his time installing my outlet so that I could use my dryer. I highly recommend Robinhood Electric. I will utilize again."

"The technician was very knowledgeable, friendly and helpful. He did an excellent job providing advice about the project and installing our natural gas heater according to our directions. It did take a little longer than expected, but nothing major.Also, because of this, the technician was called away to check on other jobs and to pick up parts. However, he kept us advised and made sure to take our schedule into consideration."

"Jason, the plumbing tech, arrived right on schedule with his only knowledge of the project a second-hand description of the work needed through a supervisor from Freier's Comfort by Design. He went right after the water line installation, since he had everything he needed on hand for that portion of the job and had that part of the installation, including the sewer venting and first level sewer line installation, finished before noon. He needed more parts to finish the sewer line connection to the main sewer pipe. We agreed to have him finish the project the next day, Tuesday.
After a delay caused by an emergency water line, Jason arrived with the necessary parts and finished the job quickly and professionally. He double-checked everything and left us with a huge improvement in our home's efficiency. I am a DIY sort of person and I don't usually hire people to do work I can do just as well. In Freier's Comfort by Design's case, there is no way I could do the work better for much less money. Both of the techs Freier's Comfort by Design have sent to our home have been quick, efficient, professional, and incredibly respectful of our home.

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
