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 few of the more common AC issues we come across include:
- Low Refrigerant Levels: Low refrigerant means there’s a leak somewhere. Minor leaks may just need a recharge, but major ones require repair before topping off the system.
- Frozen Evaporator Coils: Frozen coils usually mean something’s off—like restricted airflow or a refrigerant issue—both of which hinder cooling performance.
- Dirty or Clogged Filters: Clogged air filters reduce efficiency and strain your system, often leading to bigger issues down the line.
- Electrical Failures: Issues like bad wiring, failing capacitors, or tripped breakers can stop your AC from turning on or running properly.
- 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.
We’re here to get your system running again quickly and affordably. Contact our HVAC experts if you have any 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 these less-obvious Maryland Heights air conditioning issues include:
- Compressor Failure: A failing compressor usually means serious repair or replacement. Regular service helps spot trouble before it gets expensive.
- Refrigerant Line Damage: Small line leaks may not be obvious at first, but they gradually affect how well your system cools your space.
- Sensor Malfunctions: Faulty sensors can throw off your system’s timing and airflow, leading to performance problems and wasted energy.
- Blower Motor Burnout: When the blower motor wears out from constant use, airflow stops. Regular maintenance helps catch signs of strain early.
A lot of AC issues build over time. With proactive maintenance, you can stop them before your system shuts down on a sweltering day.

Signs You Might Need AC Repair
- AC kicks on and off too often without running long enough.
- Less airflow through your ducts and vents.
- Strange or loud operational noises you haven’t heard before.
- Drips, puddles, or moisture near the air conditioner.
- It’s harder to keep your home comfortable like you used to.
Whether it’s a minor fix or a red flag for something bigger, these issues are worth addressing sooner rather than later.
