This post is to inform building owners of the meaning behind the termHVAC.”

“HVAC” is pronounced: “H” “VAC” – this is not understood by most, and for good reasons, given the complex breadth of the mechanical contracting trade.

A building may, or may not include Heating, Ventilating, or Air Conditioning (HVAC) systems. Of course, most buildings – residential and commercial – do include a heating system, which is essential in most of these United States. But most owners of heating systems do not know what type of heating system theirs is. So, here is a brief categorical breakdown.

H-V-A-C is broken down, as follows…

Here in New Hampshire, every building – intended to be occupied by humans in winter – has some type of heating system, but not all are “central heat” systems.

If/when you have a heating “emergency,” it will be helpful when you call an HVAC contractor/service company (in New Hampshire) to explain to them:

  1. What type of heating system you have.
  2. What type of fuel/gas your heating system utilizes.
  3. What the nature of your heating service issue is.

Happy heating!

What is “Indoor Climate Control?

Indoor Climate Control (ICC) includes all equipment and systems that affect the Temperature; Air Quality; and Humidity of a space, and includes “HVAC” systems, as previously described. HVAC and ICC are often grouped together under the heading, “Mechanical Contracting.”  Mechanical Systems also include Fuel Tanks & Piping; Ducting; Fossil Fuel Venting; Kitchen Exhaust & Make-up Air (MUA); Combustion Air Supply (CAS); Snow- & Ice-Melting Systems; Pool Heating and Potable Water Heating; Fire Sprinkler/Suppression Systems… and this list is not even complete!

No wonder building owners are generally ill-informed about the meaning of HVAC; I can’t even recite it completely, and I have 37 years in the trade!

In 1996, John created his 1st invention - a circulator flange tool, then, in 2-1/2 years invented the flanges and flanged valves that became industry standards with his License Agreements with Taco, Inc., in 1999. John has a Business Management degree from New Hampshire Technical Institute, in Concord, and a year of Mechanical Engineering studies from same. John became President of New Hampshire Inventors Association in 2000, and merged it with New Hampshire High Technology Council, in 2001. John has served as Sales Engineer for 2 years at other companies, that both down-sized and John returned to self-employment and formed Protech HVAC, LLC, in 2006 and moved to the New Hampshire Seacoast to 'set up shop.' In 2010, John invented a product line of components for the HVAC trade and manufactures them in NH, ME and MA, giving him the 2nd greatest number of product units on Forced Hot Water Heating Systems - pipe and fitting makers have more product units than John. John is a Wordpress site developer, and created this site, as well as: www.innovativetradessolutions.com; www.johnwrocheleau.com; and several other sites. John has copyrighted software - Quote-Rite Job Estimating & Costing System, and Bill-Rite Invoicing System (business forms) for Tradesmen. John owns Innovative Trades Solutions, LLC, which makes his mechanical and business products. John is a writer and is penning 2 books - an autobiography and an expose on how industry players hi-jacked his flanged valve inventions. John is a musician - 5-string banjo; guitar and student of diatonic harmonica. John is an organic vegetable, and wildflower gardener.
