Thermostat is Set Incorrectly
Check if your thermostat is set to: system - “cool”. Remember that your fan settings and system settings are different and have separate functions. Your fan is responsible for circulating air while the system determines whether the A/C or Furnace is working.
The ideal A/C settings are Fan: Auto or On and System: Cool. If your thermostat is set to these settings and your A/C is still not working correctly, then the air blowing over the indoor coil could be coming out “hot”, making the home hotter.
Solution: Turn your A/C unit off and call your technician.
Dirty or clogged air filters or coils can impede the process of cooling down the air.
Solution: Make sure to change your filters often. Call your technician for a yearly maintenance to clean the coils.
Outside Unit is Not Getting Power
Two components, an indoor and an outdoor unit, comprise your A/C system. If your indoor unit is blowing air throughout your home, but your outdoor unit (which supplies the Freon) isn’t getting power, your home will not cool.
Solution: Call your technician.
· A/C unit needs maintenance
· Low on Freon (Refrigerant)
