"Tom did a fabulous job with the whole house plug installation for my back up generator. He was quick and efficient and cleaned up well after the work. He explained how to use the plug and manual interlock and made sure everything worked before leaving. Quality job on all fronts. Pricing was fair and he was able to fit me in on short notice due to another job rescheduling. I will definitely contact him again should the need arise."

"We needed a 240V (level 2) EV charger installed in our garage. Our contractor friend highly recommended Charles. Charles looked at our current electrical panel which is almost 40 years old and had no space to add new circuits. He recommended we replace the panel with a larger one and promptly provided an estimate. We also asked Charles to install a generator inlet connection and an interlock switch for the panel so that the EV battery can be used to provide backup power in case of a power outage. Once we approved the project, Charles gave us a time and duration and he got the job done on schedule. He came back again to rearrange some circuits in the panel so that the EV battery can provide power to the important functions in the house such as kitchen, refrigerator, furnace, den, etc. Overall, we are very pleased with the work done by Charles and we have no hesitation in recommending him."

"Mike is the business owner and the electrician so he will be the one doing the work or he may sub out some of the easier work or trenches, etc. He ran a line out from the panel on our house to an out-building and put a new panel and a number of circuits in the building and installed LED lights. He also added some light fixtures inside our house. I thought he did a very nice job and talked me through things that I did not understand. He was willing to work with me if there were things that I wanted to do myself. Communication was good--he kept me up-to-date on how things were going and what his schedule was. He was working on other projects at the same time, so we talked about when it would work for him to be working on my project and when he would be on other projects and what my timeline was. The panel, trench, circuits, and outlets all look great. I will work with him again if I need more work done."

"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."

"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

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.
