You set the thermostat, the AC is running, and most of the house feels comfortable. But one bedroom, office, or bonus room still feels warmer than everything else.

Uneven cooling is common, especially during hot, humid summers in Baldwin County and along the Gulf Coast. The cause may be something simple, or it may point to an airflow, ductwork, or insulation issue.

Quick Takeaway: A room that stays warmer than the rest of the house is often dealing with an airflow, ductwork, insulation, or heat-gain issue. It does not automatically mean the AC system needs to be replaced.

Start With the Air Vent

Check the supply vent in the warmer room.

Make sure it is fully open and not blocked by:

• Furniture
• Curtains
• Rugs
• Dust or debris

Hold your hand near the vent while the AC is running. If the airflow feels much weaker than in other rooms, there may be a problem farther inside the system.

Check the Air Filter

A dirty air filter can restrict airflow throughout the home.

Rooms farther from the indoor unit may feel the effects first. Check the filter and replace it if it looks dirty.

During heavy summer use, filters may need to be checked more often, especially in homes with pets or allergies.

Consider Sun Exposure

Some rooms naturally absorb more heat than others.

Rooms with several windows or strong afternoon sun can warm up quickly during a Baldwin County summer. West-facing rooms may feel especially hot late in the day.

You may be able to reduce heat gain with:

• Blinds or blackout curtains
• Solar shades
• Window film
• Improved weatherstripping

Look at the Ductwork

If airflow is consistently weak, the ductwork may be part of the problem.

Air can escape before reaching the room if a duct is:

• Leaking
• Disconnected
• Crushed
• Poorly sealed
• Improperly sized

Ductwork running through a hot attic can also affect comfort if it is damaged or poorly insulated.

Because most ducts are hidden, a professional airflow evaluation may be needed to find the problem.

Check for Insulation and Air Leaks

Sometimes the room is getting cool air, but heat is entering faster than the AC can remove it.

Poor attic insulation, older windows, worn weatherstripping, or air leaks can all contribute to uneven temperatures.

This is especially common in:

• Bonus rooms
• Rooms above garages
• Home additions
• Rooms with vaulted ceilings

Avoid Closing Other Vents

Closing vents in cooler rooms may seem like a way to push more air toward the warmer room.

However, HVAC systems are designed to operate with a certain amount of airflow. Closing too many vents can increase pressure in the duct system and may create additional comfort problems.

When to Call Pride HVAC

Consider scheduling an evaluation if:

• Airflow from the vent is noticeably weak
• The problem started recently
• Several rooms are uncomfortable
• The AC runs constantly without improving comfort

During a Gulf Coast summer, every room should feel comfortable. If one area of your home is always warmer than the rest, Pride HVAC can help identify the cause and recommend the right solution.
