If your inside unit's evaporator coil is dirty it makes it tough for refrigerant (or “Freon”) to absorb heatfrom your air. A dirty condenser can block the release of absorbed heatfrom the refrigerant. Basically, both issues will cause your system to run constantly since it's struggling to remove heatfrom your home.

How cool should my house be if it's 100 outside? More specifically, for our area, most systems are designed to lower your indoor temperature about 20°F from the outdoors. So, on days when it's 100°F outside, and your system is running at its peak efficiency, your indoor temperature will likely never maintain a level lower than about80°F.

Can I run just the fan on my AC? It is more energy efficient to run the fan without the air conditioner, but only in certain situations and for short periodsof time. The truth is that your ducts are going to heat up when it gets really warm outside, and this is especially true if they are located in your attic or under your floor.

Does outside temperature affect air conditioner? Outside Temperature. The lower the temperature of the outside air, the more cooling is done by the heat exchanger, instead of the compressor. When the outside air temperature increases, the air-conditioner works harder tocool the home because the compressor works more.

What happens if AC runs too long? Unit Too Large: If your system is too large, it won't effectively remove moisture from the air in your home, resulting in anoutput of moist, clammy air. It will actually have shorter run times than it should and use excessive amounts of electricity, resulting in higher utility bills.
