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 QUESTION: We had a power outage the other day, and we had to reset the S3000 Thermostat for our A/C Unit. Now it blows semi cool air,kind of warm actually, but the room temperature is 83 for 3 days now,and the A/C was set to 67 but it not so cool at all actually, we are still getting semi cool air, it is about 90 degrees out side. Should we shut the A/c unit off , by the thermostat, or is it is safe to still let it run with the semi cool air, until the A/C comes companycomes out.It should be allot colder in here, it was working fine before the power went off here in the neighborhood a couple of days ago. By still running it by the fan only and not on auto, it that okay to do. Will the A/C motor or compressor burn up. Or it could have a leak with freeon,not sure, like I said it was working fine before and we even shut off the main breaker and waited 5 minutes and turned that back on,thinking maybe the breaker went off. Which it was tripped. It should be cooler in here than what it is. I called a place today and they can't come out till Thursday to check it, 4 days from now. July 4, 2009.I think the digital thermometer needs to be reset ,maybe my friend set it to heat instead of cool, not sure what happened. But it shows in the window on the thermostat,it is 67 on cool, and the inside temp is 83 on the thermostat for 3 days now. Help?????
ANSWER: Cindy,
It sounds like your outdoor unit has stopped running, have you looked at it and checked? If it is not running and the breakers you reset are for it ( if not check that breaker the same way ) then after trying the breaker and it doesn't work, the next thing to do is to keep the fan on and turn the system switch to off until a tech can look at it. Normally, I will tell a questioner to check the fuses in the outdoor disconnect box with the breaker off at the local hardware store, but sometimes when you have an outage it is a brown out before failure which can damage parts in the unit and replacing a burnt fuse will only make the problem worse. You might try the power company, some have techs to establish this type of thing as they are the ones you are buying the power from.

QUESTION: The air handler is on top of the roof, I am in a 7 story building and I am on the 1st floor.The actual air conditioner itself, is on the roof above the 7th floor.
The fan is on. But it seems to run either on the program that is pre-programmed at 78 that is set in there or the if I put it on "fan',run only, it still is not so cool in here and stay's at 78, but the inside temp is 83 no matter I do, that does not budge.So does that mean when it is 83 degrees in here,the motor is suppose to kick in and coolit to 78 ,correct. Well that does not seem to cool it down enough, So I turned it to 67, and ran it on 'fan", which runs , continuously, but again it doesn't seem to cool it down to 67. So should I keep it on the slide button to just run it on "fan" anyway. If I shut the thermostat to off, how is the fan going to run, I have to have it on a certain temp and it is "suppose" to run on what ever temp you set it to then correct?? A little bit of air is better than no air, but don't want to do something to run the a/c unit down or burn a motor out correct. If it does not have enough freeon it, then can they recharge it with freeon?? So is "fan" okay to run it, instead of the "program set is at 78 for now. The a/c company I called, a different one who installed the actual digital thermostat,I really don't think maybe that is working properly it is a S3000 digital thermostat, I even put new batteries in it, if the batteries are not good would that have an effect. I wouldn't know if the a/c air handler what is on top of the roof if it is running or not. Should I go up there and see if the fan is running within the unit on top of the roof. I wouldn't know where the breaker is on that??
Thank you for answering my questions it is greatly appreciated sir.
Answer Cindy,
Actually the A/C unit is on the roof. You probably have an air handler in your ceiling. If your in a condo or apartment that is usually the way they are. But, yes the unit on the roof is what runs when you are asking it to reach a lower temperature, ie, it is 83 and you want it 78. Turning it lower to 67 only means that if it was working that it will run longer to reach that temperature if it was running correctly. But, it sounds like the roof unit is not on. having the thermostat set to off and the fan set to on is what I am trying to tell you to do. That will eliminate any damage to your unit on the roof in case something else happened. And yes it can be fixed, or freon added. The batteries only affect the program you run, does not affect the temp. over ride or the fan switch. It would take the super of your building to find the breaker
