Quick Answer: Fixing a heat pump that is freezing up in Brilliant typically costs $150–$4,000 depending on the cause. Minor airflow or sensor issues cost $150–$500. Defrost board or fan 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 weather, crawlspace duct heat loss and electric-only operation are common contributors in Brilliant homes.
Here is what causes freezing — and what it costs to correct it.
Why Is My Heat Pump Freezing Up in Brilliant?
Quick Answer: Heat pumps in Brilliant freeze up due to airflow restriction, poor crawlspace duct insulation, defrost malfunction, refrigerant imbalance, or outdoor fan failure. Electric-only homes increase winter runtime, raising icing risk.
Freezing typically occurs when:
- Static pressure exceeds 0.8” WC
- Crawlspace ducts lose heat before reaching living space
- Defrost cycle fails every 30–90 minutes
- Refrigerant charge is low
- Outdoor fan motor stops running
Cold crawlspaces lower return air temperature, increasing coil icing potential.
What Is the Most Common Cause of Freezing in Brilliant?
Quick Answer: In Brilliant, crawlspace duct heat loss and restricted airflow are the most common causes of freezing, followed by defrost control malfunction.
Root cause ranking:
- Poor crawlspace duct insulation
- Airflow restriction
- Defrost control malfunction
- Refrigerant imbalance
- Outdoor fan motor failure
When ducts run through unconditioned crawlspaces below 40°F, coil temperatures drop faster.
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 that does not clear after a full defrost cycle is not normal.
Defrost cycles should activate every 30–90 minutes. Persistent ice signals airflow or defrost imbalance.
How Much Does It Cost to Fix a Frozen Heat Pump in Brilliant?
Quick Answer: Repair costs range from $150–$4,000 depending on severity. Minor airflow or duct insulation issues cost $150–$500. Defrost board or 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 |
|---|---|---|
| Dirty filter / airflow issue | Minor | $150–$500 |
| Crawlspace duct issue | Minor | $150–$500 |
| Defrost sensor failure | Minor | $150–$500 |
| Defrost board failure | Medium | $500–$1,500 |
| Refrigerant leak | Medium–Major | $500–$4,000 |
| Compressor damage | Major | $1,500–$4,000 |
Ice does not determine cost. Measured diagnostics do.
How We Diagnose a Freezing Heat Pump in Brilliant
Quick Answer: Diagnosis includes static pressure testing, crawlspace duct inspection, refrigerant verification, defrost timing confirmation, and blower motor amperage testing.
Our process includes:
- Static pressure testing (target under 0.8” WC)
- Crawlspace duct insulation inspection
- Superheat and subcool verification
- Defrost timing confirmation
- Outdoor fan amperage test
Cold ductwork lowers delivered air temperature and increases icing risk.
How Long Does It Take to Fix a Freezing Heat Pump?
Quick Answer: Diagnostics typically take 45–90 minutes. Minor airflow or duct corrections are often completed the same visit. Refrigerant or compressor repairs may require additional scheduling.
Repair time depends on verified mechanical cause.
When Should You Call Immediately?
Quick Answer: Call immediately if the outdoor unit is fully encased in ice, airflow indoors 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 entire 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 crawlspace duct insulation was not addressed, airflow was not measured, or refrigerant leaks were not verified.
Temporary fixes may include:
- Adding refrigerant without leak detection
- Ignoring duct insulation deficiencies
- Skipping static pressure measurement
Measured repair prevents recurrence.
Why Proper Diagnosis Matters
Quick Answer: Simply thawing ice or adding refrigerant without correcting airflow and duct insulation often leads to repeat freezing. Proper testing prevents unnecessary repeat service calls.
We are not the lowest-priced option.
We focus on:
- Verified airflow measurement
- Confirmed refrigerant balance
- Defrost timing calibration
- Warranty-backed repairs
Long-term reliability matters.

Frequently Asked Questions About a Freezing Heat Pump in Brilliant
Can crawlspace ducts cause my heat pump to freeze?
Quick Answer: Yes. Poorly insulated crawlspace ducts reduce return air temperature and increase coil icing risk when outdoor temperatures hover around 30–35°F.
Duct inspection confirms the issue.
Can electric-only homes increase freezing risk?
Quick Answer: Yes. Electric-only systems run longer during cold weather, increasing coil exposure and icing potential.
Runtime measurement verifies load stress.
Will freezing damage the compressor?
Quick Answer: Continued operation while encased in ice increases compressor strain and internal pressure imbalance. If airflow is restricted, compressor damage risk rises.
Switch to emergency heat if defrost fails.
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.
