Since 1968, John has been involved in HVAC and refrigeration sales, selling residential and commercial HVAC/R installations, manufacturer’s products to distributors, and HVAC software. He was the owner/operator of Walsh Refrigeration on Cape Cod, MA, where he and his crew installed refrigeration units, including specially designed lobster tanks and environmental chambers, and HVAC systems.

John was an instructor in several Vo-Tech schools in New England. In addition, John has taught continuing education courses for the past 14 years.

John holds a Universal EPA Certification and is certified in Asbestos Abatement from Tufts University.

John has also worked as the sales manager for Wrightsoft. Today, he is a master distributor for Elite Software, assists the company as a beta tester for new programs, and is the United States trainer for Elite Software.

Currently John runs Training for the Trades where he teaches courses to HVAC, plumbing and electrical technicians. Seven instructors are available to teach courses in a wide range of technical topics. Some of the organizations that have hosted TFTT classes include distributors from one coast to coast, a Kansas weatherization group and the New York Transit Authority.

A popular course offered through Training for the Trades is on computerized heat loads. The class is offered on-site as well as through the web. Some of the classes are approved for continuing education in many states. The web class, which was designed to help technicians receive training when it is most convenient for them, has also been approved for Continuing Education in many states.

John is author of "Hit the Load J", the simplistic way of reading a manual J.

Energy Auditing

The Energy Audit program calculates monthly and annual heating and cooling costs for residential and light commercial buildings. Virtually any type of cooling and heating system can be simulated by Energy Audit including standard DX evaporative air source heat pumps water source heat pumps direct exchange heat pump sand all types of fossil fueled furnaces and boilers including two stage and modulating boilers. An optional version of Energy Audit with appliance capabilities can calculate appliance and hot water energy use as well. Still another option available is for utility companies that want to show disaggregated past utility bills. Energy Audit uses heating degree days weather bin data and full load cooling hours in its calculations. Weather data for over 1500 cities throughout the world is built-in to Energy Audit and additional weather data can be easily added. Along with calculating energy costs Energy Audit also performs an economic analysis that allows you to compare system types and costs over any given study period. There is even a loan lease and credit card analysis report designed to demonstrate affordability of better systems by showing that the effective net monthly cost is often very low when monthly energy savings are considered. To make system comparisons easy Energy Audit allows you to manually enter equipment data or automatically look it up from ARI and GAMA equipment data files. Pictures for numerous equipment models are included as well. Energy Audit provides a wide selection of nicely formatted color charts graphs and reports.

Duct Design

Manual D Ductsize works as a component within Drawing Board and Rhvac to calculate optimum duct sizes. It automatically creates runout ducts in each room of your floor plan and assigns them the proper air flows as calculated by Rhvac. Reports show the static pressure loss of each individual duct as well as the cumulative loss at each point in the system.

Calculation Method
The Manual D Ductsize Program is based on the design procedures given in ACCA's Manual D. The equal friction sizing method is used to determine optimum duct sizes to the nearest inch or centimeter. You can also select to size ducts based on a user-defined schedule of sizes or exact (nearest tenth of an inchor millimeter). Or you can select Presize for the sizing method and enter your own diameter or height and width for the duct. Static pressure losses resulting from fittings and dampers are based on Manual D's equivalent length definitions with the several hundred fitting definitions from Manual D built in to the program Including pictures.
