"Ideal experience with this company! They contacted me and came out to make the bid the same day I contacted them. They were super flexible and worked to accommodate my schedule. I needed to wait until my EV charger arrived from the manufacturer. They came out the day after it arrived, installed the unit in under two hours, and it's been working flawlessly ever since. Don't let their name fool you--John's Waterproofing is expert at electrical work! I will use them again."

"I am so grateful for this company. Micheal Townley is extremely knowledgeable and professional. He took the time to go through his assessment and upfront pricing. I had an odd electrical problem which lead to a bigger problem that could have been dangerous. After getting an absolutely shocking diagnosis from another company that left me stressed and crying for days, I hesitated to try anyone else but, Micheal put my mind at ease. I sent him pictures ahead of him coming out and he got right to work following further inspection of my electrical panel. I have additional work that will be completed by this company soon. I highly recommend Wind River."

"The whole experience with 3 Mountains Plumbing was outstanding from Nicole at the office to Jon Marc and Peter, the plumbers. They originally scheduled me for an appointment 5 days out, but Nicole watched appointments carefully and moved my appointment to the same day I called. Jon Marc, the plumber, was very knowledgeable and professional. He gave me different options, which allowed me to decide what worked best for me. He even gave me a teacher discount. After installing my water heater at 8:00 p.m. at night, he discovered a manufacturing problem with the water heater. He called another plumber, Peter. Peter was going off shift and was at the office, but got another water heater and brought it to my house so Jon Marc could install it! I think other plumbers would have said that they needed to come back the next day, but Jon Marc stayed until 10:00 p.m. installing the water heater. I will never use another plumbing company because 3 Mountains is the best! Nicole, Peter and Jon Marc... Thank you!"

Generator Install questions, answered by experts

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. 

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

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

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
