Uneven Cooling in House — What’s Causing It and How to Fix It
Is one room in your house freezing while another feels like a sauna? That’s a common issue we hear from Texas homeowners. Uneven cooling in house isn’t just annoying—it could be a sign that your AC system is struggling or something is out of balance.
At FERSA HVAC Heating & Air, we help you get back to consistent, comfortable temperatures in every room.
Why Does My House Cool Unevenly?
There are a few reasons why your home may not cool evenly. Some are simple fixes. Others point to bigger issues that need attention.
Here are the most common causes:
- Clogged or dirty air filters that block airflow
- Blocked or closed vents in some rooms
- Poor duct design that restricts airflow to certain zones
- Old or failing AC units that can’t keep up
- Improperly sized HVAC systems that cool too fast or too slow
- Insulation problems that let cool air escape
Our technicians inspect your entire system to pinpoint the real cause.
Quick Fixes You Can Try First
Before calling for service, you can check a few things yourself:
- Make sure all vents are open and unblocked
- Replace your air filter if it’s dirty
- Use ceiling fans to help circulate air
- Check for leaks around windows and doors
- Try closing blinds during the hottest parts of the day
If none of that works, it’s time to bring in the pros.
When It’s More Than Just an Airflow Issue
Sometimes uneven cooling means your AC is wearing out—or was never properly sized in the first place.
Look for red flags like a system that runs nonstop but never cools all rooms evenly, frequent repairs over the last year or two, an AC unit that’s over 10 years old with outdated components, or rising energy bills with little comfort in return. These signs often mean your system is no longer performing efficiently.
If that sounds familiar, it might be time to think about a system upgrade.
FAQs – Fixing Uneven Cooling in Your Home
Will sealing my ducts help?
Yes! Leaky ducts can waste 20–30% of your cooled air. Sealing or insulating ducts is a great way to improve overall comfort.
Can I fix uneven cooling with a smart thermostat?
It helps. Smart thermostats with zoning features can manage temperature better across multiple rooms.
Do I need a bigger AC unit to cool all rooms evenly?
Not always. Bigger isn’t always better. The key is having the right size for your home’s layout and insulation.
