Reliable generators & service you can count on

I’m Darrin Coleman, owner of Mountain Generator Services.

I understand the fear and confusion around choosing the right generator for your home or business and keeping it maintained.

With more than 20 years of experience selling and servicing generators, I can help ensure you get a generator that suits your needs and works when you need it most.

Keep the power on in 3 easy steps:

1

Find your generator

I'll arrange to visit you at your home or business to assess your needs and discuss options for which generator would be best for you.

2

Install your generator

I will handle your installation at your home and business and test the generator to ensure it will start up when the power goes out.

3

Maintain your generator

I offer an annual maintenance plan intended to keep your generator functioning properly, and to maintain your warranty.

What you should ask before you buy:

What size of generator do I need?

The size and kW capabilities of your generator should match your individual needs.

The first thing you need to decide is what you want to keep running in a power outage, only the basics, or the entire house or business.

How long is the warranty?

The warranty for generators varies by brand and reseller. It’s important to compare the length and terms of your generator’s warranty.

Briggs & Stratton, which is the only brand sold by Mountain Generator Services, has the longest warranty of any generator on the market. Find out more (opens in PDF).

What's involved in the maintenance?

Keeping your generator properly maintained is imperative for your warranty, and for your peace of mind.

Most people believe that generator maintenance only involves changing the engine oil. While this is important, it is only a small part of the annual maintenance that is required to keep your generator running at peak performance.

Among the parts that need to be checked or replaced annually are:

  • Spark plugs
  • Air filter
  • Valve adjustments
  • Voltage sensors
  • Oil warmers
  • Gas press
  • And many more.

Some of these items require special tools that most homeowners do not own.

Therefore, enlisting the services of a certified Master Service Technician to perform annual maintenance on your generator is highly recommended. Learn more about our Maintenance Plans.

What my customers are saying:

  • We met Darrin Coleman at a Home Show, we were specifically looking for a generator as we live in the country. We talked to another generator salesman and he was able to tell us the actual cost of the generator with installation and then we moved on and found Darrin. Again, we got all the information on the generator and asked Darrin how much it would cost, he told us how much the generator, the pad it would sit on, the additional services of the electrician and a length of copper piping. He said that the total cost would change depending on how much copper piping we would need, so he couldn’t give us a final quote until he came out to the house to look where our generator would go. We chose Darrin as he was much more honest with us than the other gentleman. He services our generator yearly to make sure it is always working well.

  • I have been dealing with Mountain Generator Services for all my generator needs for at least 15 years or more, and I have always been more than happy with their service! I live at least 2 hours away, and whenever I have had an issue they have been to my place within 24 hours, which is amazing! I heat and cool my house with hydro, so I need my generator working at all times, especially in the winter. I know no matter what, I can rest assured that Mountain Generator Services will be just a phone call away. Thank you so much for your excellent service!

  • Darrin Coleman of Mountain Generator Services installed our standby generator in May of 2009. Since that time, we have had Darrin provide the routine maintenance on our generator. Darrin is a very personable individual and has always proven to be very reliable, competent and knowledgeable. We would have no hesitation with recommending Mountain Generator Services.

  • I met Darrin in June of 2007. After major blackouts and periodic power outages since moving to Navan in 2002, we decided to look into getting a generator. One of my clients had met Darrin in 2006 and was very pleased with their generator installation and his service, so they referred him to us. Darrin provided a quote and all the professionals required to do an install of a generator in a couple of days. The installation was completed at the end of July in 2007.

    Darrin proposed a Briggs and Stratton Intelligent System for us, as this would automatically switch to the generator in the case of a power outage. Darrin asked us which appliances were the most important so he could select the order of what would restore first to prevent any overload of the system. This system allows you to use your entire home up to the capacity of the generator.

    Darrin provides annual servicing of the generator to keep it running top notch.  We still have the original battery!

    We have had two instances where lighting strikes nearby our home caused damage to various components of the system.  Darrin was able to acquire a control board, which was damaged in July 2012, and the power switch was damaged in a storm in the summer of 2014.  Both issues were resolved promptly and our generator is purring away.

    Power outages continue to occur periodically in the area either due to weather related issues or expansion of the power grid but whenever an outage happens, we don’t worry as we have our generator kick in within 30 seconds.

    If you need a generator when a power outage occurs, Darrin is your man!

  • We bought our generator from Darrin Coleman in 2008. He organized all services needed for the installation. It was very efficiently done. Darrin contacts us to make a yearly maintenance appointment & check-up on our generator. This is a valuable service.

    We have never had a problem with our generator. However, we know that Darrin would be there to fix it on short notice. Darrin stands by the product he sells. He is reliable & available. It is a great comfort to know we have back-up electricity with our generator, along with a dedicated sales/service man with Darrin.

    We would definitely recommend Darrin Coleman and his business.

  • I’ve had my generator for 8 years and am delighted with the security it provides me. When the weather gets bad, I don’t
    worry because I know I’ll be fine. The auto-on means that I don’t even have to think about it. When the power goes down (& living in a rural area it does), I wait 2 minutes & then everything goes back to normal. I don't even have to worry about re-fuelling it, as it's hooked right into my home propane supply.

    I settled on this one after checking around & getting quotes. I had an idea of what size I would likely need, and Darrin didn’t try to up-sell me. Darrin has been servicing the generator annually & I have every confidence in it because I know it’s taken care of by someone knowledgeable & reliable. Peace
    of mind is priceless.

  • The total experience with Mountain Generator Services has been first class, from sales and installation to annual service calls. Mr. Coleman provides friendly, efficient service and is a pleasure to deal with.


    Fred C.

  • We purchased a Briggs & Stratton standby generator from Darrin Coleman in 2010. He managed the installation at our home near Burritts Rapids and has provided annual maintenance and occasional service, as needed, since then. We are very satisfied.

  • Awesome service. Would highly recommend.


    Barbara McElroy

  • As emergency workers, we wanted to ensure our home was protected for those occasions when we can’t be home on account of the jobs we hold. We did our research and after meeting Darrin felt confident we were getting a superior product with excellent customer service and a great warranty. There have been several power outages since we had it installed in January 2019, and have been thoroughly impressed with the seamless power it provides and runs our household. It gives us great peace of mind knowing no matter where we are, that our greatest investment—our home—is protected.
