If you live in West Chester, PA, you already know how brutal the summers can get. The humidity hits you like a wall, and the last thing you want is your AC quitting on you. At DiBiase HVAC, we fix problems fast—and more importantly, we help you understand what’s going wrong, so you’re not caught off guard.
Let’s break down the top 5 AC problems we see in West Chester homes and what to do about them.
1. Your AC Is Blowing Warm Air
This one’s a classic. You turn on the AC expecting cold relief, but all you get is warm air. Annoying? Absolutely. Here’s why it happens:
- Dirty air filter: When your filter’s clogged, airflow gets restricted.
- Low refrigerant: If your system doesn’t have enough refrigerant, it can’t cool.
- Bad thermostat: Sometimes it’s not the AC, it’s the brain that controls it.
Fix it: First, check your thermostat. Set it to “cool” and lower than the room temp. Still blowing warm? Change the filter. Still no luck? Call us. You might have a refrigerant leak, and that’s not a DIY job.
2. Weak Airflow or Hot/Cold Spots
You feel air coming out—but it’s barely there. Or your bedroom’s freezing and the living room’s hot. That’s not how a working AC system should act.
Why it happens:
- Blocked vents or closed dampers
- Leaky or crushed ductwork
- Failing blower motor
Fix it: Walk around your house. Are any vents blocked by furniture? Are the filters clean? Still have problems? We can check for duct issues or a worn-out blower.
And if your home’s older (West Chester has a lot of them), your ductwork could be outdated or undersized.
3. AC Won’t Turn On
It’s hot. You hit the switch. Nothing.
No hum. No air. Just silence.
Common reasons:
- Tripped breaker
- Thermostat batteries are dead
- Wiring issues
Fix it: First, check your electrical panel. Flip the breaker off and on. Still no power? Check your thermostat, replace the batteries. If it still doesn’t respond, it could be an internal issue. That’s when you call us. We’ll test the system safely and get you running again.
We also offer same-day service in West Chester, because when it’s 90°F out, you don’t have time to wait.
4. Strange Noises or Weird Smells
Air conditioners should be quiet. If yours sounds like a dying animal or smells like something’s burning, shut it down. Something’s wrong.
Noises to listen for:
- Screeching = belt or motor issues
- Clanking = loose parts
- Buzzing = electrical trouble
Smells to look out for:
- Burning smell = electrical issue
- Musty smell = mold in ducts or filters
Fix it: Don’t ignore it. Weird sounds and smells usually mean you’re close to a bigger, more expensive breakdown. We can diagnose and fix the issue fast, before it gets worse.
5. Your Energy Bills Are Going Up
If your utility bill’s climbing but you’re not changing how you use your AC, something’s up.
Possible causes:
- Dirty coils
- Low refrigerant
- Old system that’s no longer efficient
Older AC units have to work harder to cool your home. That means more electricity and higher bills.
Fix it: Sometimes it’s as simple as a tune-up. Other times, it’s time to look at a newer, energy-efficient system that saves you money long-term. We’ll walk you through your options and help you decide if it’s worth the upgrade.
Why These Problems Happen in West Chester
Here’s the truth: West Chester has older homes, tree-lined neighborhoods, and humid summers, the perfect storm for HVAC problems.
If your system’s over 10 years old, and you haven’t had it serviced regularly, it’s not “if” you’ll have problems, it’s “when.”
And if you’re relying on window units or an old central system, you’re probably overpaying every month.
