Expertise

*******************I am the Senior tech for COLUMBIA HEATING AND COOLING in PORTLAND OREGON. 503-624-2704. ***********************IF YOU ARE LOCAL AND WANT SERVICE CALL AND SET UP AN APPOINTMENT. I work days, so I can only answer early in the day or later in the evening. I only answer public questions for residential equipment. I am very well versed in gas, electric and heat pumps and will only answer residential applications. I have been known the past decade or so, by my employers as the guy you send when no one can figure it out. Trouble shooting is my special. I understand the physics behind air flow, refrigerants and electricity. I understand programmable t-stats, zone controls, economizers, fossil fuel kits and the engineering thought process in the wiring and construction of residential equipment

Experience in the area

I was lucky enough to start in this field almost 30 years ago as an installer, for a company that installed the best duct systems I have ever seen, even to this day. The best ,as far as understanding the way air really flows through a duct system, from the return air to the very last supply register . They also had great pride and the duct work was put in, not only to last 50 years, but to look exceptional. Then as I started doing service work, I was again fortunate that I found a 3 year engineering class being put on be a man that was the educational director for the Entire united states for a society called " the Refrigeration Service Engineering Society " And for the next 3 years I schooled at night and practiced what I learned during the day, a great advantage over schooling and then trying to remember it years later.. Versed in duct design manual J heat gain/loss calculations.

Organizations

Refrigeration Service Engineer's Society

Publications

I have 2 inventions that have gone through the process and been recorded at the National Institute of Standards and Technology from start to finish and thus been invited to national innovation workshops by the dept. of Commerce and the dept. of Energy. They are waste heat recovery devices that N.I.S.T approved as valid and am currently looking for marketing partners to get this product into the hands of consumers and make a BIG difference in Energy savings for every Household and Eatery and take a big bite in the the peak hours power consumption that face our Utilities companies.

Education/Credentials

factory training in Lennox ,Rheem, Ruud ,Trane, Tempstar ,Carrier, Day&Night, Payne, Bryant, Coleman, Intertherm, York, Goodman, Ultra boilers, Unico, Mitsubishi,Sanyo, Taylor, Nicewonger, Navien. Associates degree in Refrigeration Engineering. Certified with Energy Department, Check-me Program, P.T.C.S (performance tested comfort systems ), have N.A.T.E. certifications in gas, a/c & heat pump.

What do you like about this subject?

Physics never lie. With a true and complete understanding of these laws as they apply to the hvac field, every question of the refrigeration cycle can be answered with accurate measurements. Technology is changing just as fast as the field, so there is always something new to be learned.

What do you still hope to achieve/learn in this field?

I strive to be the very best I can be and the best at what I do compared to others, my piers. I continue to go to any and all seminars, schools and tech classes and always will. I am generally the first to arrive at any training and ALWAYS sit in the middle of the front row.

Something controversial or provocative about this subject

Most folks believe that is is as simple as fixing the hole in the O-Zone that is because of the discharge of refrigerants in the atmosphere. When in fact the Montreal Protocol was drafted and signed in a whirl wind fashion pushed by lobby persons funded by DUPONT whose patents were up on the current freons and that they, DUPONT, already had the replacement freons ready to go.

The relay is in the furnace section.  Depending on the age it will be an actual relay or it could be a control board.  Follow the wires from the blower motor, they should be black, yellow, white, blue

2012-05-21 Fan:

Pat,    Hi, I just happened to be at the computer when this came in.  I need to know a bit more.  If this is the same "everything" you have been using, indoor, outdoor, thermostat, ect. or if anything

2012-03-09 Ductless systems:

Jeff,    No that will not work.  All indoor "heads" have a circuit board that get a variable strength signal from the outdoor unit board and inverter.  It also gets its power from there and the amount

2012-03-06 replacing pilot control:

Dale,    The most important part of the control is good grounds.  The GND should go to the common side of the low voltage transformer. TH and TH-w are the same and the 25 volt is the hot side of the low

2012-02-22 Armstrong Air Ultra 5 furnace:

Jim,    The fact that you had a breaker trip ( which means that somehow the amp draw on that circuit was exceeded ) and you are describing sparks, it is time to get a tech out to diagnose the furnace.
