"Tom Brown did an excellent job. He was very efficient and knowledgeable. He obviously knew how to install an electric car charging station. He was neat and did a great job of locating the charging unit. He did the work for less than his estimate and finished early. I recommend him for your electrical work."

"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 needed a Tesla charger installed in my garage. They showed up to the house quickly, and were very knowledgeable on what to do and what i needed. They installed it within an hour, with very quality parts, and were very neat and tidy about it too. No issues since install! I definitely would consider them again in the future!"

"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."

"3 Mountains plumbing installed a new toilet in the master bath. It required the first trip to unplug the old one and another to install the new one. I didn't have to pay another dispatch fee. Both plumbers were friendly, competent and had a sense of humor as well as the helper on the 2nd trip. I was given a choice of fixtures and prices so I could decide which would fit the budget. I felt in good hands and would use 3 Mountains in the future."

Generator Install questions, answered by experts

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

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.
