More About Protech HVAC

I became self-employed in 1988, then changed my business name to Protech HVAC, LLC, in 2004 when I moved to Rye, NH. Ever since, my team has been designing & building systems to conform to any building and its owner’s and occupants’ needs – virtually everything Indoor Climate Control. You name it, if it involves moving air, water, humidity, refrigerant and temperature we can do it, expertly.

2016 marks the 36th year I’ve been in the HVAC trade and I’ve been expanding my knowledge and experience ever since. My 1st job in the trade was as an oil burner technician, for Tenney Fuels, Inc. I came across this sign in a friend’s collection and took a picture of it. The company was formed as Tenney Coal Company, in 1942, changed their name to Tenney Coal & Oil, in the ’50s, then became Tenney Fuels, Inc., after dropping coal in the early 1970s.



This Gravity Hot Air (GHA) heating system started its life in the late 1800s, was 1st a coal-fired furnace, then was converted to oil by “Tenney Coal & Oil”, in 1957. I cleaned the furnace in the early 80s. In 2010 I was hired to re-build it with a new burner and controls, etc., but I showed the owner how dirty the 3′ X 1′ wooden return air duct was (runs down the cellar wall at right, then becomes a trench that runs beneath the snow blower and furnace) – it had never been cleaned, and she decided to have me replace the entire system.



At least 50% of the heating systems I learned on were ancient hold-overs from coal-burning days that were converted to oil after WWII. Timken Rotary Burners, Iron Fireman, Winkler, GE, Kalamazoo, and the one above – a Sunbeam furnace and Quiet Heet burner – were regularly on my service call schedule. As time passed, newer systems replaced these massive, in-efficient models, and I rarely see anything like this today.

This is the Forced Hot Air (FHA) system that replaced that ole relic.

Today, I build the best systems my customers’ budget lets them buy, using the best products I can find, including New England Made – Innovative Trades Solutions, LLC (ITS) – products of my own design. 7 are visible (1 is hidden) in this picture.

Virtually all forced hot water heating circulators sold in America and Canada today connect to flanges and valves that incorporate features from my original inventions, that I licensed to Taco, Inc., in 1999. Read my inventing story.

Recently, we Designed & Installed (3) Hydro-Air/Radiant-floor, Air Conditioning and Heat Recovery Ventilation (HRV) systems, as well as the complete (3) Bath and (1) Whole-House Exhaust systems, Humidification & De-humidification systems, Chimney Stainless Steel Liner, LP Gas Piping, Fireplace Inserts, #2 Fuel Oil Line & Filter, (2) Oil Burners/Boilers and Domestic Hot Water Heating… all the piping and duct-work in a 6,700 square-foot home, in Rye Beach, New Hampshire.

This project became the BETA test for some of my new mechanical designs: Circulator Flanges, Tees, Valve Handles, Instruction Holders and Plaques. See our Made in The USA HVAC Products page to see more.

When the job wrapped up, I wrote “Pictures and A Thousand Words” to show our new installations and the systems they replaced, and where our ITS products fit in with systems.

HVAC Pictures and A Thousand Words

HVAC Pictures and A Thousand Words is a 20-page 8-1/2″ X 11″ booklet written by John Rocheleau about his HVAC systems – designs/installations – in a 6,700 square-foot New Hampshire Seacoast home. This booklet includes before and after images of the new systems and the ones they replaced. Many of my new mechanical products/patented inventions were installed on the new systems that I designed and built over the course of 7 months. A solid recommendation was made by the owner on page 2. This HVAC systems story is mostly pictures with captions below.

We consistently have the 2nd greatest number of product units (the pipe/fittings maker has more) installed on our forced hot water heating systems, thanks to the experience we gained from this very satisfied customer in Rye Beach.
