Air Conditioning and Heating Efficiency

Dear Client,

With another hot Texas summer on its way, many are thinking about opportunities to make older air conditioning systems operate more efficiently. 

One would think that decreasing the outside air would improve the systems performance.  Actually, we would caution not to reduce the amount of outside air being drawn into the air conditioning system.  By decreasing the outside air, the exhaust system in the building will still be pulling in the same amount of outside air.   Instead of the hot outside air coming in through the air conditioning system and being cooled first, it will come in through the doors, the windows, and any other openings, and not be cooled at all.  Often, this unconditioned air being drawn into the building will cause the opposite effect resulting in higher temperatures and humidity levels in the space.

If you have any questions about your system design or operation, please give us a call.   We can help you evaluate your system's deficiencies and design the appropriate solutions.
