Quick Answer: Fixing a heat pump that is freezing up in Wintersville typically costs $150–$4,000 depending on the cause. Minor airflow or sensor issues cost $150–$500. Defrost board or motor repairs cost $500–$1,500. Refrigerant leaks or compressor damage cost $1,500–$4,000.
If your outdoor unit is icing over during 30–35°F damp weather, especially in a two-story home, the issue often involves airflow imbalance or defrost malfunction.
Here is what causes freezing in Wintersville — and what it costs to correct it.
Why Is My Heat Pump Freezing Up in Wintersville?
Quick Answer: Heat pumps in Wintersville freeze up due to vertical airflow imbalance, defrost control failure, refrigerant imbalance, or outdoor fan malfunction. Attic-installed air handlers increase freezing risk when airflow is restricted.
Freezing commonly occurs when:
- Static pressure exceeds 0.8” WC
- Return air is undersized in two-story layouts
- Defrost cycle fails to activate every 30–90 minutes
- Refrigerant charge is low
- Outdoor fan motor stops running
Attic air handlers operating in 20–30°F attic conditions experience greater temperature swings, affecting airflow and defrost calibration.
What Is the Most Common Cause of Freezing in Wintersville?
Quick Answer: In Wintersville, vertical airflow imbalance in two-story homes is the most common cause of freezing, followed by defrost board malfunction and refrigerant imbalance.
Root cause ranking:
- Vertical airflow restriction
- Defrost control malfunction
- Refrigerant imbalance
- Outdoor fan motor failure
- Attic condensate or sensor exposure
Long vertical duct runs increase static pressure, especially in homes over 1,800 square feet.
Is It Normal for a Heat Pump to Freeze at 30–35°F?
Quick Answer: Light frost during damp 30–35°F weather is normal. Ice thicker than ¼ inch or ice remaining after a full defrost cycle is not normal and requires service.
Defrost cycles typically activate every 30–90 minutes during frost conditions. If ice remains after defrost, airflow or sensor imbalance is likely.
How Much Does It Cost to Fix a Frozen Heat Pump in Wintersville?
Quick Answer: Repair costs range from $150–$4,000 depending on severity. Airflow or sensor corrections cost $150–$500. Defrost board or fan motor repairs cost $500–$1,500. Refrigerant leaks or compressor damage cost $1,500–$4,000.
Freeze-Up Repair Cost Breakdown
| Cause of Freezing | Repair Type | Cost Range |
|---|---|---|
| Airflow imbalance | Minor | $150–$500 |
| Defrost sensor issue | Minor | $150–$500 |
| Defrost board failure | Medium | $500–$1,500 |
| Outdoor fan motor | Medium | $500–$1,500 |
| Refrigerant leak | Medium–Major | $500–$4,000 |
| Compressor damage | Major | $1,500–$4,000 |
Cost depends on confirmed diagnostics — not visible ice alone.
How We Diagnose a Freezing Heat Pump in Wintersville
Quick Answer: Diagnosis includes airflow measurement across vertical duct runs, static pressure testing, refrigerant verification, defrost timing confirmation, and attic equipment inspection.
Our process includes:
- Static pressure testing (target under 0.8” WC)
- Supply and return temperature split measurement
- Superheat and subcool verification
- Defrost cycle timing test
- Attic air handler inspection
Stack effect in two-story homes can shift airflow balance between floors.
How Long Does It Take to Fix a Freezing Heat Pump?
Quick Answer: Diagnostics typically take 45–90 minutes. Minor airflow adjustments are often completed same visit. Refrigerant or compressor repairs may require additional scheduling depending on parts availability.
Repair time depends on measured root cause.
When Should You Call Immediately?
Quick Answer: Call immediately if the outdoor unit is encased in ice, airflow upstairs is weak, breakers trip repeatedly, or the system runs without heating below 35°F.
Immediate service is required if:
- Indoor temperature drops below 60°F
- Ice covers the full coil housing
- Auxiliary heat runs continuously
- Electrical breaker trips
Continued operation increases compressor strain.
Why Does My Heat Pump Keep Freezing After It Was Repaired?
Quick Answer: Repeat freezing usually occurs when airflow imbalance in vertical duct systems was not corrected, refrigerant leaks were not verified, or defrost timing was not confirmed.
Temporary fixes may include:
- Adding refrigerant without leak detection
- Replacing boards without airflow measurement
- Ignoring attic duct design
Measured repair prevents recurrence.
Why Proper Diagnosis Matters
Quick Answer: Simply thawing ice or adjusting refrigerant without verifying airflow in two-story duct systems often results in repeat freezing. Correct measurement prevents recurring winter service calls.

Frequently Asked Questions About a Freezing Heat Pump in Wintersville
Why does my upstairs freeze first?
Quick Answer: In two-story homes, vertical airflow imbalance and stack effect reduce supply air to upper floors. If static pressure exceeds 0.8” WC, airflow decreases upstairs first, increasing freeze risk.
Airflow testing confirms imbalance.
Can attic air handlers cause freezing issues?
Quick Answer: Yes. Attic-installed air handlers experience temperature swings that affect airflow and sensor calibration. Cold attic air below 30°F increases defrost stress and refrigerant migration risk.
Proper inspection is required.
Will freezing damage my compressor?
Quick Answer: Continued operation while encased in ice increases compressor strain and internal pressure imbalance. If airflow or refrigerant is incorrect, compressor damage risk increases.
Switch to emergency heat if not defrosting.
Do you charge overtime for freezing repairs?
Quick Answer: Overtime rates apply for non–Priority Service Maintenance Plan members after normal hours. Priority members and warranty-covered systems receive scheduling priority during winter demand spikes.
Clear policies prevent confusion.
What guarantees do you offer?
Quick Answer: Repairs are protected under our Service Trust Guardian with up to 5 years of labor coverage when maintenance is documented. New systems are covered under our Lifetime Trust Shield.
