What to Do When Your AC Runs But Doesn’t Cool in Annapolis, MD

Whether you live in downtown Annapolis or in the surrounding Anne Arundel County area, the summer sun can be a scorcher for residents of the Chesapeake Bay area. When your air conditioning system runs but fails to deliver cool comfort, it throws a wrench into your plans for relaxation.

There are several reasons why your AC might be running without producing cool air. Don’t worry; Grove Heating & Cooling is here to help you troubleshoot a malfunctioning AC and get your cool back.

This guide breaks down the common issues that lead to this cooling efficiency problem and provides easy-to-follow troubleshooting steps you can try yourself. However, for some issues, air conditioning repair by a professional HVAC technician is necessary.

Common Reasons Why Your AC Runs But Doesn’t Cool

Low Refrigerant Levels

Refrigerant acts as the lifeblood of your AC system, absorbing heat indoors and releasing it outdoors. Low refrigerant levels can significantly reduce your AC’s ability to cool. This can be caused by leaks or natural degradation over time.

Frozen Coils

The evaporator coils, located inside your AC unit, absorb heat from the air. If airflow is restricted or the refrigerant level is too low, the coil can freeze, hindering heat absorption and cool air production.

Dirty Air Filter

A clogged air filter will restrict airflow across the evaporator coils, reducing efficiency in absorbing heat. A dirty filter also forces your AC to work harder, potentially leading to overheating and malfunctions.

Blocked Condenser Unit

The condenser unit, typically located outside your home, releases heat absorbed indoors. If the condenser coils are clogged with dirt, leaves, or debris, it can’t expel heat effectively, causing the system to malfunction.

Faulty Thermostat

A malfunctioning thermostat might not be communicating correctly with your AC unit, leading to improper cooling or even continuous running without cooling.

Troubleshooting Your Air Conditioning System

If your air conditioner is running yet you don’t feel cold air coming into the house, try these troubleshooting steps to see if a quick and simple fix does the trick.

  1. Check the Thermostat: Ensure your thermostat is set to “cool” mode and the desired temperature is lower than the current room temperature. Look for any error codes displayed on the thermostat. A quick consult with your thermostat’s manual can help you understand these codes.
  2. Check the Fan Settings: The thermostat also controls the fan in your HVAC system – if the fan is set to “on”, it will constantly run. When the air conditioner is off and not producing any cool air, you’ll feel warm air coming through your vents. Make sure the fan is set to “auto”.
  3. Clean or Replace the Air Filter: Inspect your air filter. If it’s dirty or clogged, replace it with a clean one. Most air filters need changing every 1-3 months, depending on usage and household dust levels.
  4. Inspect the Condenser Unit: Turn off your AC unit at the thermostat before venturing outside. Visually check the condenser unit for any debris buildup around the coils. You can carefully remove leaves, twigs, or other loose objects. Avoid using sharp objects to remove debris from the fins, as this can damage them.

When to Call an HVAC Professional

If you’ve tried the troubleshooting steps above and your AC is still struggling, it’s time to call for backup: a qualified professional from Grove Heating & Cooling. Here are some signs that professional help is needed for air conditioner repair:

  • You Suspect a Refrigerant Leak: Refrigerant leaks require a certified technician to repair and recharge the system. Tampering with refrigerants can be dangerous and is illegal in most areas.

  • Electrical Issues: If you suspect electrical problems with your AC unit, turn off the system immediately and contact a professional HVAC technician. Electrical issues can pose a safety hazard.
  • Strange Noises: Unusual grinding, clanging, clicking, or screeching sounds coming from your AC unit might indicate failing components that need professional repair or replacement.
