Why Doesn’t My AC Cycle Off?Published on: August 31, 2014
During the hottest days of summer, it’s completely normal for your AC to run for hours at a time as it works to beat the heat. However, if it keeps running non-stop when the temperature drops at night, during rain, or on a cooler day, it may be a sign that something is wrong. And of course, the more it runs, the more energy it uses, so have it checked for these problems as soon as possible.
Unlike with cars, home air conditioners shouldn’t lose their refrigerant charge over time. Leaks do happen though, and when they do, the charge can quickly drop and send an AC’s efficiency plummeting. If your AC has lost refrigerant, be sure that the tech finds and repairs the leak before he charges your system to avoid a repeat of the problem in a few months.
Leaky or dirty ducts can choke off your AC system’s air flow or send cooled air into your attic instead of your home. With less cold air coming out of your vents, your air conditioner will have to work longer and harder to cool your home.
Other Air Flow Problems
Your air conditioner may have its air slowed in other ways. A dirty filter can reduce its ability to pull warm air out of your home, and in turn reduces the amount of cold air it can return to your home. A dirty blower fan or a short in the blower fans motor can also reduce the amount of air it pulls through your system.
Compressor Too Hot
The outdoor compressor is key to air conditioner operation because it expels the heat your AC system takes out of your home. If it isn’t getting good air flow or if it’s in direct sunlight, your entire AC system will lose efficiency.
