Five months of Liberty summer wears on your AC
Your air conditioner runs from May through September here, with summer afternoons averaging 86°F. That is a long stretch of the compressor cycling on and off most days, and the strain shows up as reduced cooling or a system that runs constantly trying to keep up.
Clay County has also logged 94 hail events and 116 damaging wind events over the past ten years, with hail as large as 2.75 inches. That kind of weather bends the thin fins on your outdoor unit's coil and can damage the fan blades, both of which cut down on how well the unit cools your house.

A new air conditioner would save little on running costs in Clay County, so the repair decision comes down to the unit's condition.
Estimates for a typical Clay County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Missouri fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
- Why is my AC not blowing cold air?
- The most common cause is a dirty air filter cutting off airflow, so check that first. A refrigerant leak will also cause this, and so will a coil that has frozen over from restricted airflow. If the filter looks fine and the air is still warm, a contractor will need to check the refrigerant charge and the coil.
- Why is my AC leaking water?
- Your AC makes water as it cools the air, and that water normally drains outside through a condensate line. If that line clogs, the water backs up and drips inside instead. A dirty filter can also cause this, since blocked airflow makes the coil freeze and then leak as it thaws. Either way, a contractor can clear the line and find out why it clogged.
- Why won't my AC turn on?
- Check the thermostat first. Dead batteries or a setting knocked out of place will stop the system before it ever starts. If the thermostat looks right, a tripped breaker or a blown fuse at the outdoor unit is the next thing to check. Liberty gets 116 damaging wind events a decade, and a power blip during one of those can trip a breaker without anyone noticing. If power is reaching the unit and it still won't start, a contractor will need to look at it.
