Common AC Issues We Identify
Peak heat can challenge any AC system—even those in good shape. Our experts are ready to troubleshoot and make the right fix right away.
A couople of the more common AC issues we encounter include:
- Low Refrigerant Levels: Refrigerant doesn’t get used up—it leaks out. If levels are low, we’ll find the leak and either recharge the system or repair it, depending on severity.
- Frozen Evaporator Coils: A common result of airflow blockages or refrigerant loss, frozen coils prevent your system from properly lowering indoor temps.
- 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.
It’s our job to get your system back online as quickly as possible at minimal cost. Contact our HVAC experts if you have any additional questions.
Less Common AC Issues That Regular Maintenance Can Identify
Most AC problems are routine, but some less common ones can be costlier and more disruptive. The upside? Regular HVAC maintenance can catch many of them early.
Some of the less obvious Chesterfield AC 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: Tiny pinhole leaks can slowly reduce system efficiency, often going unnoticed until your home isn’t cooling properly.
- Sensor Malfunctions: Bad readings from damaged sensors can cause your AC to cycle too often—or not enough—hurting efficiency.
- Blower Motor Burnout: Continuous strain can wear down the blower motor, but preventative service can help extend its life or catch issues before they escalate.
Left unchecked, many of these issues get worse with time. Maintenance helps you catch them early—before your home turns into an oven.

Signs You Might Need AC Repair
- Your AC keeps starting and stopping in short bursts.
- You’ve noticed a drop in airflow strength.
- Your system is making unusual noises like buzzing or banging.
- You see leaks or excessive moisture near the unit.
- Your indoor comfort level has declined without explanation.
Even small issues can point to bigger trouble ahead, so it’s smart to act before they get worse.
