Aboutjohn 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.

Question 2 months ago we had work done to our Goodman AC unit-
The first repairman cleaned coils and added freon. The
second repairman thawed unit again, set blower on high,
adjusted freon level,calibrated thermostat because it was
3 degrees off. Today when I come home, the AC doesn't
kick on when I set it to 72 degrees, thermastat reading
75 degrees in the house. Throughout the evening and the
next day, the thermastat reading doesn't change and the
AC never kicks on. I can't keep pouring money into this
AC on our budget in this economy. Any advice will be
appreciated. Thanks.
Answer Larry,
You should not have had to pay for the first call, as it did not solve anything and how long had it run ok before any of this happened? Unless someone changes things, the blower is on high speed from the factory for cooling. Calibrated the tstat? Do you mean an old mercury bulb one with a snap off front cover he twisted the spring for the reading you see through the front cover? If that is a mercury bulb, it must be level, the reading on the front isn't that important to you. What is important is that the reading on the lever you set for your comfort is correct and works. You also said the second tech adjusted your level? Does that mean they charged you again? Or did they put recovery equipment on the a/c unit or did they just blow some out in the air which is a $25,000.000 fine if they are turned in. Maybe that knowledge to the owner of the company will get them to do you right.
