"The heat exchanger went out earlier this year in my gas furnace. The company I had been using immediately quoted me $3000+ to replace it. They also recommended I just replace the whole system since it was all getting close to 10 years old. I posted this info on Facebook asking for advice and several friends recommended American. Glen thought it might be under warranty so he had me give him the serial number, sure enough it was. He had one of his guys come out the very next day to verify that it was bad, it was. He quoted me a price to get it replaced and stuck to that price. Awesome customer service. Highly recommended Glen and his crew."

"We have had glen and richie do everything from repairing a gas line to stove hookups to a complete furnace replacement. I have seen glens precision welding,so good that he is used as an expert consultant by architects and general contractors. Richie will not leave a job until he is completely satisfied with system performance going above and beyond the norm. Totally honest and reliable folks."

This memo is to express my strong recommendation for Glen Carsten and his ability to produce a trouble free HVAC system on a complex residential project…Glen was professional, well organized, and a pleasure to work with. I recommend him without reservation to execute any HVAC project.

…It was refreshing to work with a subcontractor who has the technical knowledge and skilled manpower to address the complex issues involved in building restaurants…I was impressed with American Mechanical’s relationships with the engineers, inspectors and jobsite supervisors in bringing together a successful project. The staff at American Mechanical is easy to communicate with and continues to be responsive into the warranty phase of the job.

David Hennessy

Owner – Hennessy Company

I have found Glen to be reliable, resourceful, and extremely creative throughout his projects with the Y. Glen and the staff of American Mechanical have continually accepted a variety of tasks that were vaguely defined, and provided solutions with their design and craftsmanship that not only addressed our immediate need, but often were beneficial over the long run in terms of quality and efficiency. The crew at American Mechanical seem to take great pride in their work, and are respectful of our staff and patrons…Glen has also volunteered for the Y by serving on committees seeking to solve HVAC and energy use issues, as well as spending time off the clock with the Y’s Facility Director to train him on systems and maintenance. I’m grateful for Glen’s service to the Y. He and American Mechanical have been true assets.

Jason Fry

CEO – Wood River Community YMCA

This letter is to serve as a recommendation for Jared Hillier of American Mechanical…Our company (was) contracted to perform startup services of over two hundred water-source heat pumps. Due to a concentrated construction schedule, and a deadline to get these units started up before the start of the fall semester, we were given only a five day window to perform these startup operations. This required several extended work days in a row to meet this schedule. Jared was committed to keeping his schedule flexible for the success of this startup, and worked hard to make sure no corners were cut. These units have been in operation for nearly two years, and I am happy to report that there have been no compressor failures. In addition to his great attitude, excellent work ethics, and high moral character, Jared has proven to be technically very capable as a service technician. As an HVAC equipment representative, we are often contacted by others needing help in troubleshooting…Jared sees this as a way to expand his knowledge base, and become a more valuable resource for his customers.

Kerry Gaul

Sales Engineer - Innovative Air, Inc.

…Over the years I have found Glen and his company to be very attentive in regular system maintenance as well as responding to calls that needed a rapid response time. I would not hesitate to use his company if and when I build another house in the area.

Peter Thomas

Ketchum residential homeowner

…I have worked with Jared (Hillier) for approximately 6 years…I believe Jared is the most knowledgeable, conscientious and reliable service technician serving the Wood River Valley. I give (him), without reservation, my highest level of recommendation.


Home Owner

Glen Carsten and his American Mechanical Corp have been our predominant mechanical contractor since fall of 2009. In that time, AMC has for us installed complete mechanical systems in new homes, modified, repaired and updated mechanical systems in existing north valley homes, and modified and expanded mechanical systems in several Ketchum commercial spaces…ranging in size from small, , BTU residential furnaces to several million BTU, multiple air-handler complex commercial systems…AMC shows willingness and competence to work on all of these types of systems. In most cases we have leaned on AMC to design their installations, modifications and upgrades. Glen  and AMC have shown a clear desire to produce simple, efficient and robust systems. To date we have good experiences with systems operating as intended, and in every instance AMC has stayed engaged with the project until the clients and our needs have been met.
