Common AC Problems and How to Avoid Them This Summer

avoid problems with your air conditioner by scheduling a maintenance call before the hot summer weather

When the heat of summer rolls in, your air conditioner becomes one of the most important appliances in your home or business. A well-functioning AC keeps your space cool, comfortable, and livable—but when something goes wrong, it can quickly turn into an uncomfortable and expensive situation.

At Howell-Chase Heating and Air Conditioning, we’ve helped homeowners stay cool for years. We’ve seen all kinds of AC issues—some simple, some serious—but the good news is many of them are preventable with the right maintenance and knowledge.

Here are six of the most common AC problems we see every summer—and how to avoid them.

Refrigerant Leaks

Problem: Your air conditioner relies on refrigerant to absorb heat and cool your home. When refrigerant levels are low—often due to a leak—your system will struggle to cool properly, cycle longer, or stop working altogether.

Solution: Schedule a seasonal AC inspection. Our NATE-certified technicians check refrigerant levels and inspect lines for leaks. If there’s a leak, we can fix it before it causes damage or high energy bills.

Clogged or Dirty Air Filters

Problem: A dirty air filter restricts airflow, reducing your AC’s efficiency and straining the entire system. It can even cause your evaporator coil to freeze.

Solution: Change your air filter every 1 to 3 months, depending on your system and usage. Not only does this prevent issues, but it also improves indoor air quality and helps your system work more efficiently.

Frozen Evaporator Coils

Problem: When evaporator coils freeze, your AC can’t cool the air properly. This might be caused by dirty filters, low refrigerant, or restricted airflow.

Solution: Keep filters clean, maintain proper refrigerant levels, and make sure vents and registers are unobstructed. If your coil does freeze, turn off the system and call a technician to prevent further damage.

Electrical Issues or Faulty Capacitors

Problem: Summer heat puts your AC’s electrical components under stress. Faulty wiring, worn capacitors, or malfunctioning contactors can cause your system to short-cycle, trip the breaker, or stop working entirely.

Solution: Annual maintenance includes a full electrical system check, ensuring all components are functioning safely and efficiently. Never attempt electrical repairs yourself—our trained HVAC technicians can handle these safely.

Thermostat Problems

Problem: If your thermostat is misreading the temperature or not communicating with the AC properly, it could lead to uneven cooling or no cooling at all.

Solution: If you have an older or manual thermostat, consider upgrading to a smart thermostat. They’re more accurate, programmable, and can help reduce energy costs. Also, check that your thermostat has fresh batteries and is mounted away from heat sources or direct sunlight.

Drainage Issues (Clogged Condensate Drain Line)

Problem: During cooling, your AC removes moisture from the air, which drains through a condensate line. If this line gets clogged, water can back up and cause leaks, mold growth, or system shutdowns.

Solution: Regular maintenance includes checking and flushing the condensate drain line. If you notice water pooling around your indoor unit, it’s time to call a professional.
