Beat the Heat: 5 Common AC Problems and How to Avoid Them

There’s nothing worse than a heatwave hitting—and your air conditioner calling it quits. At Jameson Heating & Air, we see a spike in service calls every summer, often for problems that could’ve been avoided with a little early attention. If you want to stay cool without interruption, here are five common AC issues and how to stay ahead of them.

1. Clogged Air Filters

The Problem:Your AC needs steady airflow to work efficiently. When your filters are clogged with dust, dirt, and debris, it restricts that flow—forcing your system to work harder and sometimes shut down entirely.

The Fix:Change your air filter every 1–3 months, especially during peak cooling season. It’s a simple step that keeps your system running smoothly and your air cleaner too.

2. Low Refrigerant Levels

The Problem:Refrigerant is the lifeblood of your cooling system. If levels are low due to a leak or improper fill, your AC can’t absorb heat from inside your home. This results in lukewarm air or, worse, a frozen evaporator coil.

The Fix:If your AC isn’t cooling like it used to, it’s time to call a professional. Our certified techs can detect leaks, refill refrigerant, and get your system back in working order.

3. Dirty Condenser Coils

The Problem:Your outdoor unit pulls heat out of your home—but when the condenser coils are covered in dirt and grime, that process gets blocked. The system overheats, runs constantly, and wears down faster.

The Fix:Schedule regular professional maintenance to clean your outdoor coils and ensure your system isn’t struggling behind the scenes.

4. Thermostat Issues

The Problem:Sometimes, it’s not your AC—it’s your thermostat. A faulty thermostat might send the wrong signals, turning the system on and off inconsistently or failing to reach your set temperature.

The Fix:Replace the batteries first. Still having problems? Consider upgrading to a smart thermostat for better accuracy, control, and energy savings.

5. Electrical or Capacitor Failures

The Problem:Your AC system relies on capacitors to start the compressor and fan. Over time, these parts can wear out—especially in extreme heat—causing your system to short cycle, blow hot air, or fail to turn on.

The Fix:These components should only be inspected or replaced by a licensed technician. Prevent surprises by booking an annual tune-up in the spring before summer stress sets in.

Stay Ahead of AC Trouble

Most AC problems start small—and grow bigger when ignored. The good news? A little proactive care can go a long way. With regular maintenance from Jameson Heating & Air, you can keep your system running efficiently, avoid mid-summer breakdowns, and enjoy peace of mind all season long.
