Top Causes for an AC Not Cooling During the Day
There are myriad reasons your air conditioner might struggle to keep up with your temperature demands, from a dirty filter to a leak. These troubleshooting tips should get your cooling system working like a champ again.
Your Thermostat Settings Need Adjustment
It may seem obvious, but if your thermostat is set to “heat” instead of “cool” mode, it won’t blow any cold air. The same will be true if you’ve set the thermostat to “fan” mode, where the thermostat will continuously blow warm air through your vents. If you find your AC not cooling during the day, set it to “auto” instead.
You may be tempted to turn the thermostat down to 70 or below in an effort to make your home comfortable. Unfortunately, the main effect of lowering your thermostat will be to make your air conditioner work even harder. If it takes strain, the unit may eventually shut down and refuse to cool your home at all, so follow the expert recommendation and set it to 78 degrees when you’re home.
You’re Letting Too Much Sunshine Into Your Home
Sunlight sure does look pretty streaming through your windows, but it does your air conditioner no favors. On a really hot day, those rays can boost the temperature in your home by several degrees. Your air conditioner might run fruitlessly in an effort to cool things down.
Give your cooling system a hand by covering your windows with curtains or shades. In the morning, keep the shades closed on the east side of your home. Later on, close the curtains on the west side.
Your Dirty Air Filter Needs Replacement
Is your AC not cooling during the day? A dirty filter could be the culprit behind your cooling woes.
Even reusable air filters aren’t built to last forever. The filter will capture dirt, pollen, soot, and other airborne contaminants continuously to block these elements from getting into your cooling system and breathing air. Whether it’s disposable or one that you clean, a clogged filter prevents fresh air from reaching your system, which can cause it to overheat and shut down.
Generally, you should replace (or clean) your filter every 30 days. Only special filters can go 90 days to one year before they need replacement.
You Have a Blocked Condenser Unit
Your air conditioning system has a condenser unit that sits outside, constantly exposed to the elements. It doesn’t take long for weeds, mud, and other detritus to choke the condenser unit. If the airflow issue leads to a frozen evaporator coil, your air conditioner may stop cooling your Westfield home completely.
To prevent this, regularly clean the area around the condenser unit and rinse off dirt with a hose.
Your Air Conditioner’s Refrigerant Levels Are Too Low
Why is your AC not cooling during the day? Could it be a lack of refrigerant? Your system needs consistent refrigerant levels to cool.
The coolant ferries warm air from inside your home to the outdoor condenser unit. If the refrigerant levels are too low, this process can’t happen. Your indoor air will steadily get warmer, so don’t wait to call our technicians to handle the refrigerant leak.
The AC Unit Size Doesn’t Suit Your Home in Westfield, Indiana
If you have a large home and your air conditioner is on the small side, it will run continuously. Some rooms might be cold, while others remain uncomfortably warm.
Bigger isn’t always better, though. If your unit is too large, it can make things frigid or, worse, cycle constantly to greatly reduce the unit’s useful life. Large units don’t balance humidity well, either. You need the perfect size air conditioner to stay comfortable.
