Why is my air conditioner blowing warm air when it should be cold?

That's one of the most common complaints. It can happen because of low refrigerant, a dirty/clogged filter, a faulty compressor or motor, or a thermostat issue. We'll run diagnostics, show you what's wrong, and tell you whether repair or replacement makes sense.

How often should I have my HVAC system maintained or tuned up?

We recommend a tune-up twice a year — once before summer for AC and once before winter for heating. Skipping it usually leads to costly repairs later.

How long does a full HVAC system replacement take?

Most full replacements take 1 to 2 days. Furnace-only or AC-only jobs are sometimes shorter. We plan installs to minimize downtime.

What's the typical cost for repairing vs replacing — and how do I know when to replace?

It depends on severity, system age, and efficiency. Systems older than 10–15 years or requiring frequent repairs are usually better replaced. We provide both repair and replacement options with full cost comparisons.

Will there be hidden fees or extra charges I didn't expect?

No. Quotes include labor, parts, permits, and disposal. If unexpected issues arise, we'll get your approval before proceeding.

What should I check before calling an HVAC technician?

Check thermostat settings, filters, breakers/fuses, vent obstructions, and look for leaks, noises, or odors. These simple checks can solve some issues before calling.

How quickly can you come when my AC or heater breaks down in extreme weather?

We offer emergency service and prioritize urgent calls (AC in heat waves or no heat in winter). We'll get to you as quickly as possible.

Do you show me exactly what's wrong (not just tell me)?

Yes. We provide photos, videos, and explanations of the failing parts so you see exactly what's wrong before deciding on repairs.

Can you help me lower my energy or utility bills?

Yes. We check duct leaks, insulation, system efficiency, and thermostats. Small fixes can cut costs, or we may recommend high-efficiency system upgrades.

Do you do anything for air quality, allergies, dust, or humidity control?

Yes. We provide upgraded filters, air purifiers, humidifiers, dehumidifiers, UV treatments, and duct cleaning for better indoor air quality.

How to Prevent Frozen Coils & Icing in Heat Pumps during Winter in Utah

Utah winters bring freezing temperatures, snow, and dry air—all of which can put extra stress on your HVAC system. If you own a heat pump, one of the most frustrating problems you may encounter is frozen coils or ice buildup. Not only does this reduce efficiency, but it can also lead to costly damage if ignored.

The good news is that frozen coils are preventable with the right maintenance and usage strategies. In this article, we’ll explain why coils freeze, what it means for your system, and the steps you can take to prevent icing during Utah’s coldest months.

Why Do Heat Pump Coils Freeze in Winter?

Frozen coils are a common winter issue, especially in climates like Utah. Several factors can cause your heat pump’s coils to ice over.

Low Refrigerant Levels: Without enough refrigerant, the system can’t properly absorb heat, leading to freezing.
Restricted Airflow: Dirty filters, blocked vents, or clogged coils reduce airflow, which can cause condensation to freeze.
Defrost Cycle Malfunctions: Heat pumps have a built-in defrost cycle to melt ice, but if it fails, frost can accumulate.
Outdoor Conditions: Snow, ice, or freezing rain can build up on the outdoor unit, restricting airflow and causing icing.
Thermostat Settings: Setting the system too low or running it constantly in extreme cold can push the system beyond its limits.

When coils freeze, your heat pump has to work harder, leading to higher energy bills, uneven heating, and the risk of permanent damage to components.

How to Prevent Frozen Coils in Utah Winters

Here are practical steps homeowners can take to keep their heat pumps running efficiently during the cold season.

Step 1: Keep Filters Clean

Replace or clean air filters every 30–60 days during the winter. Utah’s dust and air quality challenges make filters clog faster, and restricted airflow is a major cause of frozen coils.

Step 2: Maintain Clear Airflow Around the Outdoor Unit

Remove snow, ice, leaves, or debris around the outdoor unit. Keep at least two feet of clearance on all sides to allow proper airflow.

Step 3: Schedule Professional Maintenance

Have an HVAC technician check refrigerant levels, inspect coils, and test the defrost cycle before winter begins. Preventive maintenance is the best defense against icing issues.

Step 4: Check the Defrost Cycle Regularly

If your heat pump isn’t defrosting itself, ice can build up quickly. Pay attention to whether the system switches into defrost mode when needed.

Step 5: Adjust Thermostat Settings Wisely

Avoid setting your thermostat excessively low in freezing weather. A moderate, consistent temperature helps the system operate without strain.

Step 6: Insulate and Seal Your Home

Well-insulated homes reduce the demand on your heat pump, preventing overwork that can lead to coil freezing. Seal drafts around doors, windows, and ducts to keep warm air inside.

Step 7: Install a Cold-Climate Heat Pump or Backup Heat

If your current system struggles in Utah’s coldest nights, upgrading to a cold-climate-rated heat pump or adding a backup heating system can prevent frequent icing problems.

Frequently Asked Questions

Why does my heat pump freeze up in the winter?
It often happens due to restricted airflow, low refrigerant, or defrost cycle issues. Utah’s cold weather makes systems more vulnerable to icing.
How do I know if my heat pump’s defrost cycle is working?
During operation, the system should occasionally switch into a mode that melts ice off the coils. If you notice constant ice buildup, the defrost cycle may not be working properly.
Can I pour hot water on frozen coils?
No. Pouring hot water can shock the system and damage components. It’s safer to turn off the unit and call a professional if icing is severe.
Is ice on the heat pump normal?
A small amount of frost is normal in winter, but thick layers of ice or coils completely covered indicate a problem.
When should I call an HVAC professional?
If ice buildup is heavy, frequent, or prevents your system from heating effectively, call a licensed HVAC contractor immediately.

Conclusion

Frozen coils are a common but preventable issue for Utah homeowners using heat pumps. By keeping filters clean, ensuring proper airflow, scheduling regular maintenance, and checking defrost cycles, you can avoid costly breakdowns and keep your home comfortable all winter.
