About john t. borgman
Expertise
I work days, so I can only answer early in the day or later in the evening, I live in Oregon. I have been so good at all the other area's of hvac, I am probably the only hvac guy that does not know oil. ( lol ) 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
I was lucky enough to start in this field over 25 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. Also experience in wine rooms and indoor swimming pool hvac & humidity controls
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, Ultra boilers, Unico, Mitsubishi,Sanyo, Taylor, Nicewonger, . Associates degree in Refrigeration Engineering. Certified with Energy Department, Check-me Program, have N.A.T.E. certifications in gas, a/c & heat pump.

Question
Hi John,
I saw you gave some great advice, so I had a question for you. I have a Little Giant Pump Company VCMA-20 Series condensate pump attached to my Bryant condensing gas furnace. A strange thing has happened. The motor started to run all the time, only stopping if I unplugged the unit. I checked the tank; no water. So I pulled the unit out to look at it. Here is what is so strange; when the Motor Switch Float is down (e.g. there is no water to buoy it up), then the motor runs non-stop. But if I push the Motor Switch Float up to the contact cover, it turns off and the motor stops. This is the OPPOSITE behavior of how I believe it is supposed to operate, and opposite to what the installation manual states.
Any idea how my motor switch float logic could have gotten reversed? Any idea how to fix it, or do I need to buy a new one?
Thanks in advance.
Jeff
Answer
Jeff,
I have actually had that happen. The micro switch reverses it's operation. You need a new one or find a micro switch that matches the size and mount. It blew my mind when I saw it....lol
Best to get a new pump and when you do, once a year at the start of cooling season, pour some bleach followed by a gallon of hot water to kill all the pond scum that grows in the pump, which is usually the only way they fail ( except in your case )
