Heating, Air Conditioning, Fridge, HVAC/Thermostat settings


Thermostat at 75 - air from register 73. Why? Hvac runs 12 hours and cools only to 79. Would setting thermostat to 72 help?

Turning the t-stat down will not make the air coming out any colder.  The air leaving the air handler should be 15-20 degrees cooler then the air entering.  The temp should be taken as close as possible to the air handler.  It would seem to me your unit needs to be serviced.

I have been in the HVAC field for the past 18 years. I can help with most HVAC questions. I work on commerical buildings for the most part, and have yet to find anything I could not troubleshoot and repair, when repairable. I work on small 1 ton units to a 2500 ton chiller. Troubleshoot air flow, elect, and control problems. I attend regular classes to keep up with the latest and greatest.


I work on commerical sites, hospitals, gov't buildings. I can troubleshoot just about anything in the HVAC business.

5 years trade school, VFD training classes, Liebert factory training, some York and Trane factory training.
