"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!"

"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

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.

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.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.
