Have you ever walked into your house on a hot summer day, only to find it feels just as sticky inside as it does outside — even with your A/C blowing?
You’re not alone. Many homeowners are surprised to learn that cooling the air doesn’t always mean removing enough humidity. And when your indoor air is too humid, it can feel warmer than it actually is, make you uncomfortable, and even cause damage to your home.
Let’s break down why this happens — and how to fix it.
1. Your A/C Might Be Short-Cycling
If your A/C system turns on and off frequently in short bursts, it may not run long enough to properly dehumidify the air. This often happens when the system is oversized for the space it’s cooling.
What to do:
Have a professional evaluate whether your system is correctly sized and running efficiently. A tune-up can also help correct short-cycling caused by dirty coils or low refrigerant.
2. Your System Is Old or Losing Efficiency
Older systems simply don’t pull moisture from the air as effectively as newer models. If your A/C is 10–15+ years old, it may be time to consider a replacement with modern humidity control features.
What to do:
Ask about high-efficiency units with variable-speed compressors and built-in dehumidification.
3. Dirty Air Filters or Coils Are Blocking Airflow
Poor airflow means your A/C can’t move warm, humid air out of your home efficiently. Dirty filters or coils restrict this process and reduce performance.
What to do:
Change your filter regularly (we recommend once a month in peak season), and schedule professional coil cleaning during your annual A/C tune-up.
4. Your Thermostat Isn’t Set Correctly
Running your system on the “Fan On” setting instead of “Auto” can actually circulate humid air when the system isn’t actively cooling.
What to do:
Make sure your thermostat fan is set to “Auto” to prevent extra humidity from being pushed around your home.
5. You Might Need a Dedicated Dehumidifier
In very humid climates or homes with moisture issues, your A/C may not be enough on its own. A whole-home dehumidifier works alongside your system to bring moisture down to a comfortable level.
What to do:
Ask us about adding a dehumidifier to your HVAC system — especially if you’re experiencing mold, musty smells, or sticky air even with A/C on.
Bottom Line:
If your home still feels humid with the A/C running, it’s more than just annoying — it’s a sign your system might not be performing at its best. And in San Diego’s warmer months, that can mean higher bills and lower comfort.
