AC Not Cooling
in Pensacola, FL
In Pensacola, summer temperatures stay above 90 degrees for months, and the humidity makes a struggling AC feel even worse inside. The most common reasons a system stops cooling are low refrigerant, a clogged evaporator coil, or a compressor that is starting to fail. Left alone, the system will run constantly, drive up your power bill, and eventually quit entirely.
Quick Answer
When your AC runs but does not cool, it usually means low refrigerant, a dirty coil, or a failing compressor. Pensacola summers regularly hit 95 degrees with high humidity, so a weak system falls behind fast. A technician needs to check refrigerant levels, clean the coil, and test the compressor. Call (850) 972-0626 before the problem gets worse overnight.
Telltale Signs
Warning Signs to Watch For
- The thermostat is set to 72 but the house never gets below 80
- Warm air blows from the vents even after the system has run for an hour
- The outdoor unit runs nonstop without cycling off
- Your power bill jumps noticeably compared to the same month last year
- There is ice forming on the copper lines near the indoor unit
- The air feels wet and sticky even with the AC running
Root Causes
What Causes AC Not Cooling?
Low Refrigerant Charge
Refrigerant is the fluid that actually moves heat out of your home. Pensacola systems work hard from April through October, and small leaks in older coils or line connections slowly drain the charge until the system can no longer keep up.
The Fix
Refrigerant Leak Repair and Recharge
A technician finds the leak, repairs it, and recharges the system to the correct level. Just adding refrigerant without fixing the leak is a short-term patch that will fail again.
Dirty Evaporator Coil
The evaporator coil inside your air handler pulls heat out of the air. Pensacola's humid air carries dust and mold spores that coat the coil over time, insulating it so it cannot absorb heat properly.
The Fix
Evaporator Coil Cleaning
The coil is cleaned with a foaming coil cleaner that breaks down the buildup. A clean coil transfers heat the way it is supposed to, so the system cools the house without running constantly.
Failing Compressor
The compressor is the pump that keeps refrigerant moving through the system. Units in Pensacola that are 10 or more years old have worked through hundreds of long cooling seasons and the compressor wears down, losing the pressure needed to cool effectively.
The Fix
Compressor Replacement or System Replacement
A failed compressor can sometimes be replaced on its own, but on older units it often makes more sense to replace the whole system. A technician can measure compressor output and help you understand your options.
