Common AC Issues We Identify
Hot summer months can put stress on even the most reliable AC systems. Our team is ready to step in, diagnose the issue, and get things working fast.
A couople of the more common AC issues we encounter include:
- Low Refrigerant Levels: If refrigerant is low, there is a leak. A minor leak can be addressed by adding refrigerant while a major leak will need to be repaired before recharging the system.
- Frozen Evaporator Coils: Ice on the coils often points to airflow problems or low refrigerant, both of which limit your system’s ability to cool efficiently.
- Dirty or Clogged Filters: Clogged air filters reduce efficiency and strain your system, often leading to bigger issues down the line.
- Electrical Failures: If the wiring’s damaged or a capacitor fails, your system might struggle to operate—or not start at all.
- Thermostat Problems: An inaccurate or unresponsive thermostat can cause erratic cooling or prevent your system from running altogether.
- Drainage Issues: A clogged condensate line can trigger safety shut-offs or lead to water damage around your system.
Fast, affordable AC repair is what we’re known for. Contact our HVAC team anytime with questions or concerns.
Less Common AC Issues That Regular Maintenance Can Identify
Even though many AC issues are expected, rarer ones can cause real trouble. That’s why regular HVAC maintenance is key to staying ahead of them.
Some of the less obvious Lemay AC issues include:
- Compressor Failure: This high-stress part drives your entire cooling system. Catching electrical or mechanical issues early can prevent total failure.
- Refrigerant Line Damage: Tiny pinhole leaks can slowly reduce system efficiency, often going unnoticed until your home isn’t cooling properly.
- Sensor Malfunctions: When sensors misread airflow or temperature, your system may cycle at the wrong times or run inefficiently.
- Blower Motor Burnout: When the blower motor wears out from constant use, airflow stops. Regular maintenance helps catch signs of strain early.
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
- Your system turns on and off frequently (short cycling).
- Airflow that has become noticeably weaker.
- Rattling, banging, buzzing, and other strange noises.
- Leaks and excess moisture around your AC unit.
- Your home isn’t as comfortable as usual.
These warning signs—big or small—are best handled early before they lead to more serious problems.
