What Should I Do If My AC Is Not Cooling in Weirton, WV?

Quick Answer
If your AC is not cooling in Weirton, first check the thermostat, air filter, and breaker. If the system is running but blowing warm or weak air, the most common causes are restricted airflow, a frozen coil, electrical issues, or low refrigerant. Older homes and electrical limits common in Weirton often make these problems worse. If basic checks don’t restore cooling quickly, the system needs professional diagnosis.
Stop Running the AC If You Notice Any of These
Turn the system off immediately if:
- Airflow from vents is very weak
- Ice is visible on copper lines or the indoor coil
- The outdoor unit is not running or is humming but not starting
Running the AC under these conditions often turns a manageable repair into major equipment damage.
What To Check First When Your AC Isn’t Cooling
Before assuming a major failure, check these items in order:
- Thermostat – Set to COOL and below room temperature
- Air filter – Replace if dirty or restrictive
- Breaker panel – Look for a tripped AC or furnace breaker
- Vents and returns – Make sure they’re open and unobstructed
If cooling doesn’t return after these steps, continuing to run the system usually makes things worse.
Why You Can Trust This Guidance
I’m Scott Merritt, and I’ve worked in residential HVAC since 1994.
Over the last 30+ years, I’ve diagnosed, repaired, and replaced thousands of air conditioning systems and trained technicians across Ohio and throughout the Upper Ohio Valley, including Weirton.
This guidance is based on real failure patterns we consistently see in Weirton homes, not theory or generic advice.
One Important Thing to Know About Weirton Homes
In Weirton, older electrical systems and basement-installed air handlers reduce how much stress an AC system can tolerate before cooling problems appear.
That’s why small issues often show up as “not cooling” here faster than in newer construction.
Is the Problem Indoors or Outdoors?
Separating the issue this way helps narrow the cause quickly.
Indoor Problems That Stop Cooling
Most common causes:
- Dirty air filters
- Blocked or undersized return air
- Frozen evaporator coils
- Weak or failing blower motors
Indoor airflow problems are the number one reason an AC runs but doesn’t cool.
Outdoor Problems That Stop Cooling
Common causes:
- Failed condenser fan motor
- Electrical components not engaging
- Dirty condenser coils
- Compressor startup problems
If the outdoor unit isn’t operating correctly, cooling cannot happen.
The Most Common Reasons an AC Runs but Doesn’t Cool
1. Restricted Airflow
Dirty filters or blocked returns prevent heat from being removed properly and often lead to freeze-ups.
2. Frozen Evaporator Coil
Usually caused by airflow restriction or low refrigerant.
Signs include:
- Weak airflow
- Ice buildup
- Water leaks when ice melts
Running the system while frozen can damage major components.
3. Refrigerant Loss
Refrigerant does not get “used up.”
Low refrigerant always means a leak.
Common symptoms:
- AC runs constantly
- Air feels cool but never cold
- Ice forming on lines or coil
4. Electrical or Control Issues
Very common in Weirton homes.
You may notice:
- Outdoor unit hums but won’t start
- AC works at night but not during hot afternoons
- Breakers trip during peak heat
These issues are often caused by weak capacitors, aging contactors, or voltage drop.
5. Outdoor Unit Failures
If the condenser fan or compressor isn’t operating, cooling stops completely.
What We Check First on a “Not Cooling” Call
When we diagnose an AC that isn’t cooling, we don’t guess. We follow a sequence:
- Airflow measurement and filter condition
- Electrical load and voltage checks
- Indoor coil condition
- Outdoor unit operation
- Refrigerant verification (only after airflow and electrical checks)
This prevents misdiagnosis and unnecessary repairs.
Temporary Relief vs a Real Fix
It’s important to understand the difference:
- Turning the system off to thaw ice = temporary relief
- Fixing airflow, electrical issues, or leaks = real fix
Temporary relief without diagnosis almost always leads to repeat failures.
This Is Usually NOT the Cause (Important)
To be clear and honest, these are rarely the real problem:
- The thermostat brand
- “Low Freon because it’s hot outside”
- The system being “too old” by default
Not cooling does not automatically mean replacement.
Does Not Cooling Mean Repair or Replacement?
No — not by itself.
General guidance:
- Under 10 years old: Usually repairable
- 10–15 years old: Depends on the failure and history
- Over 15 years old: Repair vs replacement becomes a practical discussion
The cause of the problem matters more than the symptom.
Why Waiting Gets Expensive
AC systems don’t recover on their own.
A common progression looks like this:
Airflow or electrical issue → freeze-up or overheating → compressor damage → major repair or replacement
Early diagnosis almost always costs less.
A Real Weirton Home Example
We diagnosed a Weirton home built in the 1950s with a basement air handler where the AC ran constantly but never cooled.
The issues included:
- A severely restricted return
- A weak blower motor
- Electrical components operating near capacity
Early repair restored cooling and prevented compressor failure.
One Simple Diagnostic Question That Helps
Is the AC blowing plenty of air that isn’t cold, or is airflow weak?
That single distinction often determines whether the issue is airflow-related or electrical/refrigerant-related.
A Calm Reassurance
Most “AC not cooling” calls in Weirton are fixable when addressed early.
Panic replacements usually happen only when problems are ignored too long.
