AC Not Cooling Enough
in Chandler, AZ
When your AC runs constantly but the house stays hot, something is wrong with how the system is producing or moving cold air. Chandler sees more than 100 days a year above 100°F, and a system that is even slightly off cannot handle that load. Ignore it long enough and the compressor burns out, which is a much bigger repair.
Quick Answer
In Chandler, summer temps push past 110°F, and an undersized or dirty AC unit simply cannot keep up. The most common fixes are cleaning the condenser coils, checking refrigerant levels, or replacing a unit that was never big enough for the home. If your house is above 80°F inside with the AC running full blast, call (928) 599-7684 and get someone out before it gets worse.
Telltale Signs
Warning Signs to Watch For
- The thermostat is set to 75°F but the house sits at 82°F or higher
- The AC runs without stopping from morning through late evening
- Rooms far from the air handler are noticeably hotter than rooms near it
- You feel warm or lukewarm air blowing from the vents instead of cold air
- Your electric bill jumped but the house is not getting any cooler
Root Causes
What Causes AC Not Cooling Enough?
Dirty or Blocked Condenser Coils
The condenser unit sits outside and dumps heat out of your home. In Chandler, dust storms called haboobs coat the coils with a thick layer of dirt and debris, blocking airflow and trapping heat inside the system. A dirty coil can cut cooling capacity by 30 percent or more.
The Fix
Condenser Coil Cleaning
A technician pressure-washes the coil fins and clears any debris packed around the unit. This restores airflow so the system can reject heat the way it was designed to.
Low Refrigerant from a Leak
Refrigerant is the fluid that actually moves heat out of your home. If a line develops a leak, the level drops and the system loses its ability to cool properly. This is common in units that are 10 or more years old, where copper lines have developed small cracks over time.
The Fix
Refrigerant Leak Repair and Recharge
The technician finds and repairs the leak first, then recharges the system to the correct level. Simply adding refrigerant without fixing the leak is a temporary patch that will not last.
Undersized AC Unit for the Home
Many homes built in Chandler's Ocotillo and Fulton Ranch neighborhoods in the early 2000s were fitted with units sized to minimum code, not to handle back-to-back heat waves. When outdoor temps sit above 110°F for days in a row, an undersized unit runs continuously and still cannot meet the set temperature.
The Fix
Load Calculation and Unit Replacement
A proper load calculation figures out exactly how much cooling your home needs based on square footage, insulation, and window placement. A correctly sized unit gets replaced and installed to match those numbers.
