TV Star Shares Stories at Diamond Contractor™ Conferences

Richard Trethewey, the famed plumbing and heating expert for “This Old House” programming since 1979, was a special guest speaker at one of our Diamond Contractor™ Conferences held in Atlanta last week.

Richard TretheweyMore than 300 Diamond Contractors attended one of the two back-to-back two-day events that featured presentations from Mike Cappuccio (“Are You Making All You Can Make Selling Ductless?”) and Weldon Long (“The Power of Consistency – Rock your Business –Rock your Life”), among others.

Trethewey shared his experiences as an HVAC contractor over the years as well as some humorous HVAC stories from his projects on “This Old House.”

In addition to his role on the popular home improvement television program, Trethewey consults on residential plumbing and heating projects throughout the country, with current projects in Massachusetts, New Mexico and Hawaii.

Listening to Tretheway’s storytelling, it’s evident that his outlook on the industry hasn’t dulled over the past 30 years. In a recent interview with This Old House magazine, Trethewey shared “the HVAC innovation I’m most excited about is electric heat pump INVERTER technology. Traditional units are either 100 percent on or off. These cold-weather heat pumps use sensors to vary compressor speed based on need.”

Not only is Tretheway a long-time advocate of Mitsubishi Electric systems, but he also shares our enthusiasm for achieving maximum comfort using minimal energy. We couldn’t be happier to have him as a part of the conference’s events.

Trethewey is scheduled to speak at the upcoming conference in Las Vegas on Oct. 26-28. Click here for more information about the conference or to see if you are eligible to attend. To learn more about becoming a Diamond Contractor, talk with your local distributor.

2014 Diamond Service Advisory Conference Recap

Two of our fundamental goals as an HVAC manufacturer are to provide the best products for consumers and the environment and the best support for our customers. We founded the Diamond Service Group (DSG) program in 2003, a nationwide network of qualified Mitsubishi Electric distributors trained to provide top-of-the-line technical support. Every year, our service management team sits down with a select group of DSG members – our Diamond Service Advisors (DSA) – to discuss the current state of the program and ensure that we’re keeping our promise to our customers.

This year, our service management team and DSA gathered at the Grand Hotel Marriott Resort in Point Clear, Alabama for the two-day Diamond Service Advisory Conference. The event included in-depth discussions on everything from program engagement, the current support systems and infrastructure to future expansion, and what is needed for continued program success.

“The DSA Conference was a great opportunity for members to come together, sharing knowledge and expertise on the DSG program,” said Tony Hayes, our senior director of service and technical operations. “Our DSA members consistently collaborate with our team to provide us with DSG program intelligence only gained from years of experience at the distributor level.”

This conference is important because it keeps us in touch with the DSG program, gives us insight on what works and what doesn’t, so that we can develop purposeful goals and objectives for continued achievement for years to come.

Industry Celebrates Third Anniversary of First VRF Certification Program

October 7 Image
We introduced Variable Refrigerant Flow (VRF) zoning technology to the U.S. more than 10 years ago and currently, it’s the fastest growing HVAC technology on the market. There were two critical steps in its path to industry and end-user acceptance: the passing of Air Conditioning Heating and Refrigeration Institute (AHRI) Standard 1230 and the launch of the AHRI VRF Certification Program. This year, we celebrate the third anniversary of its success.

We began working with AHRI and other HVAC manufacturers on the program in 2003. AHRI Standard 1230, the first and only standard in the world for testing VRF zoning products, was passed in 2009. The AHRI VRF Certification Program, which validates the performance of VRF zoning equipment based on the standard, was officially launched in September 2011 with five manufacturers on board – us being one of them. To date, the program includes nine manufacturer participants and 1,367 certified models with at least 168 more expected to be certified this year. We are proud to report that all of our systems that have gone through certification verification testing over the past three years have passed! Here’s why the program continues to pick up steam:

All-Inclusive: The program tests a full range of VRF capacities, from 5,000 Btu/h indoor units to 760,000 Btu/h outdoor units. It allows manufacturers to certify ratings including full load cooling capacity, energy efficiency ratio (EER), heating capacity, coefficient of performance (COP) and simultaneous cooling and heating efficiency (SCHE). The program also provides a method for testing and rating integrated energy efficiency ratio (IEER), which involves four tests at different capacities and temperatures to simulate annual usage – this is where VRF really shines.

Third-Party Validation: Products are tested, under the direction of AHRI, at a state-of-the art Intertek facility in Plano, Texas, which was designed with input from all manufacturer participants to ensure that equipment is tested fairly and accurately. Manufacturers’ performance claims are independently measured and verified by the experienced Intertek team.

Reassurance: The program ensures that manufacturers are rating and certifying their products honestly and, better yet, adhere to a higher standard when developing VRF zoning systems. It ensures that products will perform as specified, provide predictability, optimize energy efficiency and improve client satisfaction.

M-Series Featured in Winning Passive House Design

October 7_Green Spaces NextGen Winning Design_ImageWe are proud to announce that our M-Series systems were featured in the winning design in the NextGen Homes Design Competition. green|spaces, a nonprofit that works to advance the sustainability of living, working and building in the Chattanooga, Tennessee region, hosted the competition that plans to produce four next-generation houses to sell on the local market.

The purpose of the competition was to identify the best design solutions for challenging sites with high performance energy goals. Teams were tasked with designing a single-family detached home that met the following requirements:

  • Did not exceed 2,000-square-feet.

  • Featured at least three bedrooms and two full bathrooms.

  • Construction costs did not exceed $140 per square-foot.

  • Produced as much energy as they consumed.

  • Protected and promoted human health.

  • Minimized the production of waste in day to day operations of the home.

A panel of judges reviewed the submitted designs, narrowed the list down to 10 finalists and one winning team: Team 210. When it came to the HVAC design, Team 210 wanted a system that would provide efficient operation, require minimal ductwork and aid in achieving Net-Zero Energy Building certification at a reasonable installation cost. The team decided our systems fit the bill and featured our MSZ-FE  and MXZ heat pumps in their design along with a variety of our indoor units.

Team 210 was awarded $10,000 for its winning design and will work with the project team on developing the drawings, specifications and contracts for construction – Phase II of the competition. The actual construction of the homes, the third and final phase, is scheduled for spring 2015.

We look forward to seeing Team 210’s vision come to life as they begin the next steps towards construction!

Project Profile: Governor’s Mansion, Augusta, Maine

Efficiency Maine reports that more than 5,000 ductless heat pumps have been installed in Maine since 2012. Buildings throughout the state are becoming more energy-efficient as awareness and encouragement of ductless technology continues to spread. The 181-year-old Blaine House, the mansion where Maine’s presiding governor lives, is one of them.

Our heat pump was installed in the sleeping quarters of the Blaine House in fall 2013 to provide adequate heating for the governor throughout last year’s exceptionally harsh winter season. The rest of the Blaine House, however, still relied on an oil boiler system for heating and 26 window air-conditioning units for cooling. The mansion guzzled 5,074 gallons of oil last year alone, which led to a costly $16,775 utility bill and sparked the governor’s search for a new and better HVAC system for the house.

Augusta Fuel Company (AFC), Augusta, Maine, was tapped for the HVAC makeover. AFC’s Marty Roy has a wealth of experience with our technology and immediately knew our systems would be the best fit for the job. “I knew I could save a ton of electrical work using Mitsubishi [Electric], and provide the Blaine House with a better product,” Roy said. Governor LePage was also “sold on them,” having witnessed the benefits firsthand last winter.

With everyone on board, the team installed 22 units in June 2014 to replace all the window air-conditioning units. The indoor units were painted to blend into the interior décor and the outdoor units were camouflaged behind shrubbery to maintain the Blaine House’s quaint exterior appearance. The ductless design, installation flexibility and minimal demolition allowed the project team to preserve the historic architecture. Perhaps the biggest feat? At least 75 percent of the mansion’s heating is expected to come from our systems, which will optimize the building’s efficiency and comfort while decreasing its energy costs and environmental impact.

The Blaine House makeover is one step in Maine’s plans to install energy-efficient HVAC systems in all of Augusta’s state-owned facilities, which will displace 1.1 million gallons of oil a year. To learn more about the installation, click here.

Giving it the Old College Try: College Campuses Go Green

As green home building continues to climb, it comes as no surprise that college campuses are beginning to catch up. Universities are going far beyond recycling – starting their own organic gardens, installing green roofs and solar panels, and even joining in large-scale movements to measure sustainable dining on campus.

In an effort to name the greenest college in the nation, College Prowler ranked the greenest college in each state, using a scale of one to 10. While the company chose not to release its exact criteria, it reportedly looked at schools’ eco-friendly tendencies, sustainability initiatives and number of LEED®-certified facilities. Only one school received a perfect 10 at the end of the study – Pitzer College, Claremont, California, known for its LEED-certified residential halls and low-water landscaping.

Other schools making headlines in the green movement are:

  • University of Dayton, Dayton, Ohio, is well on its way to becoming the first Catholic college in the nation to completely rid itself from coal and fossil fuels.
  • College of the Atlantic, Bar Harbor, Maine, is the first college to become carbon neutral, complete with its own personal organic farm. In addition, the school uses only recycled paper and composts all of its food waste.
  • University of California, Los Angeles, California, has a plan set in place to generate 100 percent renewable energy as well as use 100 percent local water by 2050.
  • George Washington University and American University, located in the nation’s capitol, together made the largest non-utility solar energy purchase in the U.S. as part of their 20-year plan to reduce the carbon footprint of the two universities and George Washington University Hospital. The move to solar power is said to generate more than half the universities’ electricity needs and more than one-third of the hospital’s needs.
