When winter rolls in, it’s vital for your heat pump to be in top condition. But if your heat pump is freezing up, you could be facing efficiency issues and possibly higher utility bills. Here, we’ll discuss why your heat pump might freeze and how you can fix it, with insights from Airtek, your trusted HVAC wholesaler.

Why Is My Heat Pump Freezing?

A heat pump is designed to handle low temperatures, but excessive ice buildup can hinder its function. Let’s explore some common causes of freezing.

1. Insufficient Airflow

Poor airflow is one of the primary causes of a frozen heat pump. Dirt and debris can accumulate on the air filter or outdoor unit, blocking the necessary flow of air.

Fix: Regularly clean or replace your air filters. At Airtek, we recommend seasonal maintenance, especially in winter, to keep your heat pump running smoothly.

2. Faulty Defrost Cycle

Most modern heat pumps come with a defrost mode that temporarily reverses operation to melt away frost. However, if the defrost system is faulty, ice can build up over time.

Fix: Test your heat pump’s defrost cycle. If it’s not working as expected, consider reaching out to a professional HVAC technician for inspection.

3. Low Refrigerant Levels

When refrigerant levels are low, the heat pump’s coil can freeze over due to lower-than-normal temperatures within the unit. This can happen due to leaks or simply low refrigerant.

Fix: Check for any refrigerant leaks and have your levels topped off by a licensed professional. Airtek’s team of HVAC experts can help diagnose and resolve refrigerant issues.

4. Blocked Outdoor Unit

Snow, ice, leaves, and other debris can clog the outdoor unit, obstructing airflow and causing the system to freeze.

Fix: Ensure there is at least 18 inches of clearance around the unit. Remove any obstructions, especially during heavy snowfall, to allow your heat pump to function without interference.

5. Outdoor Temperature and Humidity

Extremely low temperatures or high humidity levels can make it harder for the heat pump to prevent ice buildup, even with defrost cycles in place.

Fix: For locations with harsh winters, consider a model specifically designed to handle extreme temperatures. You can browse our selection at Airtekshop.com to find the best match for your climate needs.

How to Prevent Heat Pump Freezing

1. Schedule Regular Maintenance: Regular checkups keep your heat pump in optimal condition, reducing the risk of freezing and maximizing efficiency.

2. Monitor Airflow: Make sure your system’s filters, vents, and outdoor units are clean and clear of debris.

3. Upgrade to a Modern Model: Advanced models come with improved defrost cycles and built-in winter protection. At Airtek, we stock a variety of heat pumps suited for Canadian winters.
