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 Hi I live in north Texas where the temperature is in the 100s. We have Train XR 11 outdoor ac unit (almost 6 years old) that has been working fine until this morning. Thermostat and inside unit seem to be working fine, and the air filter looks clean. However the air blowing out of our ceiling vents is not cold. My brother said the outdoor AC unit was making an unusually loud buzzing noise this morning but no fan was turning. I went outside and now there is no buzzing, no fan... the unit looks and sounds dead, but looks very clean inside and out.
I have not powerwashed the coils because it looks clean and I don't see any cottonwood fluff or anything. It is very hot here and I would like to get my AC to work but not going to call a technician on the 4th of July.
Here is the info I wrote down on the plate on the outdoor unit.
Trane XR 11
Mfg. 08/2003
Model No. 2TTR1036A1000AA
Serial No. 33221NX5F
Answer Derek,
Check your breaker and next there is a fused disconnect on the house next to the outdoor unit. With your breaker turned off ( if it was not already from the previous check ) pull the handle inside the box and remove it and the cover under it. You will see 2 fuses, probably 30 amp or so. Those are a special slow blow fuse and I dont know if you have a hardware store open, but if so, you can have them checked and/or replaced there.
