AC Not Cooling Enough
in Boynton Beach, FL
When your AC runs nonstop but the house stays warm, something is wrong with the system's ability to move heat outside. In Boynton Beach, summers run from May through October with daily highs above 90 degrees, and a system that's even slightly off won't keep up. Left alone, the unit will work itself to death and you'll end up replacing it far sooner than you should.
Quick Answer
In Boynton Beach, summer temperatures regularly hit 95 degrees and the humidity makes it feel worse. If your AC runs all day but can't get below 78 inside, you likely have a refrigerant leak, a dirty coil, or an undersized system. A technician needs to measure pressures, inspect the coil, and check airflow. Call (561) 200-8530 before the hottest months hit and the wait times get long.
Telltale Signs
Warning Signs to Watch For
- The thermostat is set to 72 but the house never gets below 78 or 79
- The air coming from the vents feels cool but not cold
- The outdoor unit runs almost constantly without cycling off
- Humidity feels high inside even with the AC running
- Your electric bill has jumped noticeably compared to the same month last year
- Ice forms on the copper lines near the air handler
Root Causes
What Causes AC Not Cooling Enough?
Low Refrigerant From Leak
Refrigerant is the chemical that absorbs heat from your indoor air and dumps it outside. When a line or coil develops a small crack, refrigerant escapes slowly and the system loses its ability to cool. In Boynton Beach, the salt air near the coast speeds up corrosion on copper refrigerant lines, so leaks are common even in units only 5 to 8 years old.
The Fix
Leak Detection and Refrigerant Recharge
A technician uses a leak detector to find the exact spot, repairs or replaces the damaged section, then recharges the system to the manufacturer's specification. Just adding refrigerant without fixing the leak is a waste of money because it will leak out again.
Dirty or Frozen Evaporator Coil
The evaporator coil sits inside your air handler and absorbs heat from the air blowing over it. When dust and mold build up on the coil, airflow is blocked and the coil can freeze solid. Boynton Beach's high humidity means mold and bio-growth collect on coils faster here than in drier climates, especially in homes where the filter gets changed less than once a month.
The Fix
Coil Cleaning and Airflow Correction
The coil needs to be cleaned with a coil cleaner safe for HVAC equipment and rinsed so buildup is fully removed. Once clean, the technician checks static pressure to confirm airflow is back to normal.
Undersized or Aging Equipment
An AC unit sized for a 1,400 square foot home cannot properly cool a 2,000 square foot home even if it runs perfectly. Many homes in older parts of Boynton Beach near the downtown area were built in the 1970s and had smaller, less efficient units installed that were never upgraded when additions were put on.
The Fix
Load Calculation and System Replacement
A proper Manual J load calculation tells you exactly what size system the house needs. Installing the right size unit means it cools efficiently, cycles properly, and removes humidity the way it should.
