Should Your Heat Pump Run Constantly in Winter? Here’s What You Need to Know

Imagine stepping into a warm, cozy home after a long winter day in Vancouver. Your heat pump is running—but is it running too much? Should a heat pump run constantly in winter, or is that a sign something is wrong?

Most homeowners get nervous when they hear their heat pump humming along all day and night. But here is the truth: in colder weather, a properly functioning heat pump is supposed to run more often. That is how it keeps your home comfortable without skyrocketing your energy bills—as long as it is working efficiently.

Let’s clear up the confusion and help you understand whether your heat pump is running as it should—or if it is time to call the experts at Whyte Mechanical to optimize your system.

How a Heat Pump Works in Vancouver’s Winter

A heat pump does not generate heat—it transfers it. Even when it is cold outside, there is still heat in the air. Your heat pump extracts that heat and moves it indoors. When temperatures drop below freezing, the system has to work harder to find and transfer heat, which is why you will notice longer run times.

However, an efficient heat pump should still keep your home at a steady temperature without running 24/7 or driving up your utility bill.

When It’s Normal for a Heat Pump to Run Constantly

Your heat pump is designed to maintain consistent warmth, not blast hot air like a furnace. Here is when it is completely normal for your heat pump to run for long periods:

• Outdoor temperatures are near or below freezing – In Vancouver’s mild winters, a heat pump should cycle normally, but when the temperature nears 0°C, expect it to run more often.
• You have a variable-speed heat pump – Newer, high-efficiency heat pumps run longer at lower speeds to maintain comfort without big temperature swings.
• You set your thermostat to a steady temperature – Unlike a furnace, a heat pump works best when left at a consistent setting. Frequent adjustments force it to work harder and run longer.

When a Constantly Running Heat Pump Is a Problem

If your heat pump never stops running, even in moderate weather, it could be a sign of an issue. Here is what to check:

• Thermostat Settings – Make sure it is not cranked up too high. Heat pumps are most efficient when set between 18-22°C in winter.
• Dirty Air Filters – A clogged filter restricts airflow, forcing the heat pump to work overtime. Replace or clean it every 1-3 months.
• Low Refrigerant Levels – If your heat pump is not transferring heat efficiently, it may be leaking refrigerant. Call a professional to check.
• Icing or Frost on the Outdoor Unit – A properly working heat pump has a defrost cycle. If ice builds up and does not melt, your system is struggling and needs servicing.
• Leaky Windows & Poor Insulation – Drafts from windows and doors can make your heat pump work overtime to compensate for heat loss. Sealing gaps will reduce strain on your system.

If any of these sound familiar, schedule a heat pump service with Whyte Mechanical before small issues turn into expensive repairs.

How to Maximize Your Heat Pump’s Efficiency This Winter

• Set It and Forget It – Unlike furnaces, heat pumps work best when kept at a steady temperature rather than turning them up and down.
• Keep It Clean – Regularly clean or replace filters and keep the outdoor unit clear of debris, snow, and ice.
• Get Professional Maintenance – A yearly tune-up ensures your system runs at peak efficiency and catches small issues before they become costly.
