Why does my Air Conditioning run all day in hot weather?
Why does my Air Conditioning run all day in hot weather?
Assuming this is not a new symptom... this is a common complaint and can be attributed to two possible things. The first is that your system may have been designed correctly to meet the latest energy codes to perform at the highest efficiency. The other possibility is that it was not designed at all or was not sized properly in the first place. During real hot weather this can unfortunately be normal due to how air conditioning systems are designed for maximum efficiency. Air conditioning systems are designed to basically an averaged mean high temperature in your particular area, many areas are designed for say about 90 Deg F outdoor temperature and at that point they are generally at their maximum efficiency and should continue to cycle on and off with generally the run time matching the off time. The air conditioners efficiency drops when the temperature goes above this point and the system must run longer to meet the set point... common thought on this is that you will not see that many days at the higher temperature and it is worth the loss in comfort to have the maximum efficiency during the mean average outside air temperature as that temperature occurs more often. Increasing the efficiency of the air conditioning condensing unit itself (Higher SEER Rating) along with the indoor coil, while maintaining the size, will usually overcome this problem and still maintain your system at maximum designed efficiency. If your system runs all day or for extended periods during this mean average for your area then more than likely you either have a design issue such as incorrect duct sizes or the air conditioner was not sized properly in the first place.
