Understanding Your Equipment Options

Action Furnace is leading the way in the set-up of modern, residential heat pump systems. And our technicians know a thing or two about the best equipment options on the market today.

Cold Climate Heat Pumps

Designed specifically for colder regions (hello Alberta), cold climate heat pumps used advanced technology to extract heat from the outside air, even in the most frigid of conditions. These models provide efficient heating without having to rely on supplemental heating systems.

Air Source Heat Pumps

Air source heat pumps transfer heat between your home and the outside air to provide heating and cooling. They are highly efficient, widely available and easy to install. 

Ducted Heat Pumps

Ducted heat pumps use your home’s ductwork to distribute warmed or cooled air, making them a fantastic choice for whole-home comfort. 


Now each of these different types of heat pumps can come with their own unique set of issues, however for the purpose of this blog, we’ll go over the most common ones our team has come across, regardless of the equipment we’re servicing.

Issue #1 - Insufficient Heating or Cooling

Insufficient or inconsistent heating and cooling is one of the most common heat pump issues we’ve seen.

One reason could be low refrigerant levels. Refrigerant is essential for heat transfer, so if there is a leak or the level is too low, the heat pump will have a tougher time absorbing and releasing heat, reducing effectiveness.

Dirty or clogged filters could also be the culprit of heating and cooling issues, because they restrict air flow. 

Finally a heat pump that is too small will struggle to handle the temperature demands of your home; while one that is too big will cycle continuously, wasting energy and money.

Each of these can quickly cause unnecessary wear and tear on your system, so it’s important to get these addressed as soon as possible with professional service.

Issue #2 - Frequent Cycling

As briefly mentioned above, a heat pump that is frequently cycling can be cause for concern. Cycling is typically caused by an improperly sized heat pump. This is only one of the reasons why we really believe in the importance of professional installation, because our knowledgeable technicians will take the time to ensure your new heat pump is appropriately sized for your space.

Frequent cycling could also be caused by thermostat malfunction or incorrect thermostat settings. To help mitigate this, we recommend investing in a smart thermostat for enhanced control and convenience.

Frequent cycling causes intense strain on your system, resulting in premature repairs or full system replacements.

Air source heat pumps transfer heat between your home and the outside air to provide both heating and cooling. These heat pumps are prominently featured on the front of a modern house, embodying the concept of renewable energy.

Issue #3 - Freezing

A frozen outdoor unit can be a frequent issue during our harsh prairie winters that can seriously affect your heat pump’s efficiency. This occurs when a layer of ice buildup obstructs air flow and reduces the system’s ability to absorb and transfer heat. 

Common causes of freezing include poor air flow caused by dirt and debris in and around the system, low refrigerant levels, or malfunctioning defrost settings. 

Ensuring you do a seasonal visual inspection of your heat pump will go a long way to recognizing ice build up before it’s too late!

Issue #4 - Weird Noises

With a well-functioning system, noises should be minimal, so any sudden or unusual sounds typically indicate a problem with your heat pump.

A grinding noise might be a sign of loose parts, while a squealing noise typically indicates an issue with the motor. 

It’s important to be particularly aware of any banging or clanking sounds because these usually signal a failing compressor or significant issue with internal parts. 

Addressing noises right away, by tightening or lubricating components, not only restores peace and tranquility in your home, but also helps prevent further, more costly damage.

Issue #5 - High Energy Bills

Hey, you installed a heat pump to lower your energy bills. So what gives?

A sudden spike in your energy bills is usually due to inefficiencies caused by neglected maintenance, aging equipment or issues in your duct work.
