Summer in Central Virginia is no joke—and neither is a broken air conditioner when the temperatures soar. Your AC unit is your home’s frontline defense against the heat, and when it starts acting up, ignoring the signs can lead to costly breakdowns and emergency repairs.

At Browns Heating, Air & Plumbing, your trusted Lynchburg HVAC and Plumbing company, we want to make sure you're prepared.

Let’s break down the most common warning signs your air conditioner may not survive the summer—and what you can do to stay cool and comfortable all season long.

Weak or Inconsistent Airflow

If your AC is running but the airflow feels weak or uneven across rooms, this could indicate issues with your ductwork, blower motor, or clogged filters. Poor airflow means your system is overworking to cool your home—and that leads to burnout.

Tip: Weak AC airflow in Lynchburg homes is one of the top calls we receive during summer.

Warm Air Blowing from Vents

When your system starts pushing warm air instead of cold, it’s often a refrigerant issue, thermostat malfunction, or compressor failure. These issues can escalate quickly—especially during a heatwave.

Unusual Noises from Your AC Unit

Grinding, banging, screeching, or rattling sounds are never good. These noises often mean loose parts, worn-out components, or motor issues. Left unchecked, they can cause permanent damage.

Tip: Schedule prompt HVAC repair in Central Virginia if your AC sounds louder than usual.

Frequent On-and-Off Cycling

Short cycling is a sign of an inefficient air conditioner. Whether it’s caused by an oversized unit, dirty evaporator coils, or a faulty thermostat, it leads to higher energy bills and premature wear.

Higher Energy Bills Without Better Cooling

If your electricity bills are climbing and your home still isn’t staying cool, your AC is losing efficiency. Older units, poor maintenance, or refrigerant problems could be the cause.

Strange Smells from Vents

Burning, musty, or moldy smells coming from your AC vents are serious red flags. They could point to mold, wiring issues, or burned-out parts—all of which can affect your family’s comfort and health.

Water Leaks or Refrigerant Puddles

Any sign of leaking water or refrigerant near your indoor or outdoor unit is cause for concern. Left untreated, this can lead to property damage and a complete system failure.
