Common AC Issues We Identify
Even a well-maintained AC system can experience strain during hot summer months. Our team is here to prevent, diagnose, and fix problems ASAP.
A couople of the more common AC issues we come across include:
- Low Refrigerant Levels: When refrigerant is low, a leak is the cause. We can recharge minor leaks, but major ones need to be sealed before the system can be refilled.
- Frozen Evaporator Coils: When airflow is blocked or refrigerant runs low, your coils can freeze—cutting down your system’s cooling power.
- Dirty or Clogged Filters: When filters get clogged, airflow drops, efficiency suffers, and your system has to work harder—often causing bigger problems later.
- Electrical Failures: Faulty wiring, worn capacitors, or tripped breakers can prevent your system from powering on or cooling effectively.
- Thermostat Problems: When your thermostat isn’t communicating properly, it can throw off the entire system. Repair or a new unit may be needed.
- Drainage Issues: Condensate line clogs are a common culprit behind unexpected shutdowns or hidden water damage near your unit.
Getting your AC back online quickly and without a big bill—that’s what we do. Have questions? Talk to our HVAC experts.
Less Common AC Issues That Regular Maintenance Can Identify
Not all AC issues are predictable—some rare ones lead to bigger headaches and higher costs. The good news is regular HVAC maintenance often spots them before they escalate.
Some of the less obvious Maplewood air conditioning issues include:
- Compressor Failure: The compressor is your system’s core component—when it fails, cooling stops. Regular checks can catch wear before it leads to major repairs.
- Refrigerant Line Damage: Pinhole leaks are easy to miss but can steadily reduce your system’s cooling ability over time.
- Sensor Malfunctions: If a sensor isn’t reading correctly, your system might turn on or off at the wrong times, reducing comfort and control.
- Blower Motor Burnout: If the blower motor gives out, your system can’t circulate air. Maintenance reduces stress and helps spot early warning signs.
Most of these problems don’t happen overnight. Routine service can spot trouble before it leads to a total breakdown and a hot, uncomfortable house.

Signs You Might Need AC Repair
- Frequent on-off cycling that interrupts cooling.
- Weaker airflow coming from your vents.
- Odd sounds such as rattling, humming, or knocking.
- Pooled water or visible condensation around the AC unit.
- Your space just doesn’t feel as cool or balanced as it should.
Minor symptoms can signal larger problems down the line—don’t wait to get them checked out.
