AC Not Cooling in Mount Sterling, MO

An AC not cooling in Mount Sterling, MO is the most common call we take all summer. The system runs. Air moves. The house still sits at 79 degrees at 6 pm. That pattern has a short list of causes, and our crew works through it in order instead of guessing.

First we check the temperature split. A healthy central air system drops return air about 15 to 20 degrees across the evaporator coil. If the split is 8 degrees, the problem is on the refrigerant side or the airflow side, and we go looking. A clogged filter or a matted evaporator coil chokes airflow. A dirty outdoor condenser coil can't shed heat. A slow leak leaves the system undercharged, which shows up as low suction pressure on our gauges and often as ice on the suction line. Our page on refrigerant leak repair covers how we trace those.

Sometimes the unit is simply too small for the house, or ductwork in a hot attic is leaking cold air into the insulation. We'll tell you straight if that is the case.

Call (866) 703-1217 and our crew will measure what your AC not cooling problem really is before we quote a repair.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about AC Not Cooling in Mount Sterling, MO.

Talk to our crew
Is it worth repairing an older R-22 system?
Sometimes. R-22 has not been produced or imported in the US since 2020, so any recharge uses reclaimed refrigerant at a high price. A small electrical repair on an R-22 unit can still make sense. A major leak or a failed compressor on one usually does not. We'll give you both numbers.
What does SEER2 mean for my repair or replacement?
SEER2 is the efficiency rating used for new central AC equipment since January 2023. Minimums differ by region, with higher minimums in the South and Southwest than in the North. It does not change how we repair your current system, but it matters if you are weighing repair against a new unit.
Can you just add refrigerant to my AC?
We can, but it rarely makes sense on its own. A central AC system is sealed, so low refrigerant means a leak. Topping it off without fixing the leak means the charge leaks out again. We find the leak, repair it and weigh in the correct charge.
How long does a central AC system usually last?
Many central air systems run 12 to 15 years with regular maintenance. Units near the coast, where salt air corrodes coils, and units in very long cooling seasons often wear out sooner. Age alone is not a reason to replace, but it factors into repair decisions.
Why is water leaking from my indoor unit?
Most of the time it is a clogged condensate drain line, a cracked or rusted drain pan, or a frozen coil that is melting. Turn the system off to limit water damage and call us. We clear the line, check the pan and test the safety float switch.
