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 Hello,
I have a central AC unit, a Trane 5 ton. I set my thermostat to a specific temperature. The unit works fine, however once the inside temp reaches what is set on the thermostat, the condenser shuts off but the blower continues to run. Eventually I notice that the blower is still running once the room heats up a bit and I get the smell of the garage air coming into the house. The only way I can get the blower to shut off is to trip the circuit breaker and then turn it back on. Occassionaly the blower cycles as it is supposed to. Ive changed the thermostat and that hasnt helped. I have also had 2 separate techs out to diagnose, and neither tech could find the problem. Of course I could not show them the problem because the unit cyled as it should have when they were here. Have your heard of this problem and where should I diagnose?
Answer Sean, It is not uncommon for a fan switch to hang up. What I recommend is to pull off the door at the furnace that the blower is behind and you will see a deadman switch that kills the power when you pull off the door. Wrap electrical tape around it ( breaker off ) so that when you turn the breaker on and put the door on the switch will not kill power when the door is removed and next time it sticks on, call your tech and have them come and catch it in the act and repair it.
On a seperate note. You need to do some sealing or taping or something. This could be a blessing in disguise as you should not be smelling your garage through the duct system, you have some serious leakage to be repaired, which will increase the efficiency of your equipment
