Why is my AC not bringing temperature down?
A clogged filter is often at the root of many performance issues. Blocked condenser: The condenser (the outdoor unit) of an AC needs to be clear on all sides so it can exhaust heat. If the condenser is blocked or excessively dirty, the air conditioner will not be able to cool down its refrigerant low enough.
Why does my a / C keep running after it reaches a set temp?
The first time we noticed it, the thermostat was set to 77 and the temp read 75. When we bumped the thermostat up to 78, it shut off. This happens most of the time the a/c runs. Occasionally it will actually shut off once the temperature is reached.
Is it better to leave your a / C on all day or turn it off?
If you have central air — or a window unit with a thermostat — you can also save energy by setting the thermostat a little higher. ACEEE estimates that air conditioners use 3% to 5% less energy for every degree you raise the thermostat. To get the best energy savings, leave your thermostat set at 78 degrees or higher while you’re out.
What happens when you lower the temperature on your air conditioner?
Air conditioners generally only cool at one speed (though some have variable speed settings to improve energy efficiency). Lowering the temperature too much only makes your air conditioner run for longer, increasing wear and tear on your AC along with your bills.
Can a large AC system control both temperature and humidity?
Unfortunately, the answer is no. The fact is, an oversized AC system does a poor job of controlling both temperature and humidity. That’s because the powerful compressor turns on and off frequently, so the system never runs long enough to remove humidity from the air. Your AC size needs to be carefully calculated using a load calculation process.

What to do if your air conditioner wont keep up with the temperature?
Do NOT crank the thermostat down: Leave it set where you normally have it. Moving the dial from 76° to 72° will not change the temperature of the air coming out of the registers; it just makes the unit run longer to reach the desired temperature.
Why is my a / C not keeping up with the heat?
If you’re only now noticing your A/C doesn’t keep up in the heat of the day, it may not be a new problem. Start observing which rooms are hottest, what time of day is it the worse, etc. Doing this will give you and your HVAC professional clues about what’s likely the problem, or problems plural.
What happens when you turn the AC down to a low setting?
When the space is cooled down to the setting, the thermostat then turns off the compressor. So when you turn down the thermostat to a low setting, you’re just requesting that the compressor run longer to reach that temperature. It isn’t a way to make the AC work faster at its job or give you better cooling levels.
