Heat Pumps: How They Work
Heat pumps are becoming increasingly popular. So how do they work? They move existing heat around using refrigerants. This is different from a furnace that generates heat.
In the summer, a heat pump extracts heat from indoor air and expels it outdoors, cooling your house. A reversing valve allows the system to work in reverse during the winter.
This means one system for both heating and cooling. In winter, it draws heat from the outside air and transfers it inside. This reduces heating and cooling costs while utilizing renewable energy. But, there are some important disadvantages to consider.
Exploring the Advantages of Heat Pumps
Heat pumps offer year-round climate control with one unit. They handle both heating and cooling, simplifying your HVAC setup. Heat pump heating is also safer and more environmentally friendly than traditional heating systems because there’s no combustion.
Electric heat pumps significantly reduce energy bills compared to electric furnaces due to higher energy efficiency. While the upfront cost of a heat pump may seem high compared to traditional HVAC systems like gas furnaces, they provide long-term savings.
Heat pumps can extract ambient heat even in cold weather, unlike traditional heating. Pairing a heat pump with solar panels can further reduce energy consumption and lower your carbon footprint. They also provide more consistent, comfortable heat with better air quality due to longer run cycles and improved air filtration.
What Are The Disadvantages of a Heat Pump?
While heat pumps offer numerous advantages, it’s important to understand their drawbacks. This empowers homeowners to make informed decisions about their heating and cooling needs. A major consideration when exploring heat pumps is efficiency.
Upfront Costs and Cold Weather Efficiency
Heat pumps have a higher initial price tag due to their technology. Their efficiency can decrease in freezing temperatures.
Since heat pumps transfer heat rather than generate it, their heating power can diminish on extremely cold nights. This can activate supplemental resistance heating, reducing overall cost savings.
Newer cold-climate heat pumps offer improved performance in freezing temperatures. Consult with local experts like Jadex Heating, with over sixteen years of experience in Coquitlam, for tailored advice about your region’s needs.
Defrosting and Drafts
In freezing weather, heat pumps can ice over, triggering a defrost mode. This temporarily interrupts heating and can slightly increase electricity bills compared to furnaces.
The continuous airflow from a heat pump can feel drafty, especially in poorly insulated homes. The constant compressor operation can create a noticeable hum, which might bother some homeowners.
Lifespan and Noise
Modern heat pumps typically last 10-15 years, though not as long as some furnaces. A key factor is the cost of repairs over the system’s life, especially beyond the warranty period.
Consider the availability of replacement parts, especially for older models. Factor in potential price increases for replacement parts compared to replacing the entire unit. Manufacturer-installed heat pumps usually come with longer warranties that cover servicing.
Choosing the Right System
When choosing or upgrading your HVAC system, explore available rebates. Provincial rebates often incentivize energy-efficient upgrades, especially those supporting long-term sustainability goals.
Always consult HVAC professionals like Jadex Heating and Air Conditioning, leveraging our sixteen years of expertise. Don’t rely on DIY approaches, especially when warranties offer better protection and cost less than premium repair services from smaller providers who may stop servicing older models.

FAQs about broken heater
What is a major problem with a heat pump?
Reduced efficiency in extremely cold weather is a major issue with heat pumps. They struggle to extract sufficient heat, requiring supplemental electric heaters that increase energy consumption.
What is the downside to a heat pump in Canada?
Like other cold climates, the main disadvantage in Canada is poor performance in sub-zero temperatures. Efficiency decreases drastically, and the supplemental electric heating increases energy bills. However, cold-climate heat pumps designed for harsh conditions can work in some parts of Canada, according to Natural Resources Canada.
Who should not get a heat pump?
If you live in areas with consistently sub-zero temperatures, reconsider a standard heat pump. While cold-climate heat pumps are available, a traditional gas furnace might be better for extremely cold winters.
High electricity costs in your area can negate the operating cost benefits of a heat pump. Evaluate all energy costs before making a switch to ensure the long term savings make fiscal sense.
Why do people not like heat pumps?
Some find the lower temperature airflow less comfortable than a furnace, causing a drafty feeling in poorly insulated homes. The higher initial cost and potential noise can also deter homeowners. Careful consideration is needed before making a purchase.
