Why Is My Southern Maryland AC Unit Blowing Hot Air?

When the weather warms up in Owings, MD, the last thing you want is for your air conditioner to blow hot air or not work the way it should.

Many Southern Maryland area homeowners experience these common AC unit issues, especially at the start of the cooling season.

1. Low Refrigerant Levels

Why It Happens

Refrigerant is essential for cooling your home. If there’s a leak or your system is running low, your AC unit won’t cool the air effectively.

Signs to Look For

How to Fix It

Call a professional HVAC technician to locate and repair the leak and recharge the system. Refrigerant handling requires certification, so avoid DIY fixes.

2. Dirty Air Filters

Why It Happens

Clogged air filters restrict airflow, causing the system to work harder and eventually blow warm air.

Signs to Look For

How to Fix It

Replace or clean or replace your air filters every 1-3 months, especially during peak cooling season.

3. Thermostat Issues

Why It Happens

Setting the thermostat too low too quickly can overwhelm the system. Instead of cooling faster, it struggles to keep up.

Signs to Look For

How to Fix It

Set your thermostat to 72-75°F and adjust gradually by 1-2 degrees at a time. This helps maintain consistent cooling without overworking the system.

4. Frozen Evaporator Coils

Why It Happens

When coils freeze, the unit can’t absorb heat, causing warm air to blow through the vents.

Signs to Look For

How to Fix It

Turn off the air conditioner to let the coils thaw. Check for dirty air filters or blocked vents. If the problem persists, call a professional.

5. Dirty or Blocked Condenser Unit

Why It Happens

The outdoor condenser unit needs proper airflow to release heat. Dirt, debris, or nearby plants can block airflow, reducing efficiency.

Signs to Look For

How to Fix It

Clear debris around the outdoor unit. Hose down the fins gently to remove dirt. Keep at least two feet of clearance around the unit.

6. Electrical Issues

Why It Happens

Faulty wiring or a tripped circuit breaker can stop the system from running properly.

Signs to Look For

How to Fix It

Check your electrical panel for tripped breakers. If the issue continues, call an electrician to inspect your system.

What Temperature Should You Set Your Thermostat At?

For optimal cooling without overworking your system, set your thermostat between 72-75°F. Gradually adjust by 1-2 degrees until you reach your desired comfort level. Avoid setting it too low too quickly, as this can cause the system to struggle.
