Heat pumps have become one of the most efficient and practical heating and cooling solutions for Ottawa homeowners. With modern cold-climate technology, today’s systems are built to operate reliably through harsh winters while providing air conditioning in the summer.

If you’re considering a heat pump — or already have one installed — understanding how it operates, how long it lasts, and what maintenance is required will help protect your investment.

What Is a Heat Pump?

A heat pump is an all-in-one heating and cooling system that transfers heat instead of generating it.

• Winter: Extracts heat from outdoor air and moves it indoors.
• Summer: Reverses operation and cools your home like an air conditioner.

Unlike a traditional gas furnace that produces short bursts of high-temperature air, a heat pump heats differently.

Heat Pumps Deliver Steady, Consistent Heat

Furnaces create intense heat in shorter cycles. Heat pumps operate with longer, steadier run times and deliver air at a slightly lower discharge temperature.

Because of this difference, we recommend:

• Setting one consistent temperature
• Avoiding large thermostat setbacks overnight
• Allowing the system to maintain steady indoor comfort

Constant adjustments force the system to work harder and reduce efficiency. When properly sized and installed, a heat pump maintains a very comfortable, even indoor temperature throughout the home.

Why Heat Pumps Work Well in Ottawa

Energy Efficiency

Heat pumps move heat rather than burn fuel, often achieving efficiencies over 300%.

Year-Round Operation

One system provides both heating and cooling.

Hybrid Compatibility

Many homes pair a heat pump with a high-efficiency furnace for dual-fuel operation during extreme cold.

Lower Environmental Impact

Heat pumps reduce reliance on fossil fuels and lower overall emissions.

Expected Lifespan of a Heat Pump

With proper installation and consistent maintenance, a modern cold-climate heat pump typically lasts:

12–15 years on average

Some systems can exceed 15 years when well maintained.

Several factors influence lifespan:

• Proper system sizing
• Professional installation quality
• Annual maintenance
• Snow and airflow management
• Electrical stability
• Filter replacement frequency

The compressor is the most critical component. Lack of maintenance, restricted airflow, or repeated ice buildup significantly reduces its life expectancy.

Annual servicing and proactive homeowner care directly extend system longevity.

Annual Professional Maintenance Requirements

Heat pumps are advanced systems with electronic controls, refrigerant systems, defrost technology, and inverter-driven compressors. They require annual professional maintenance.

Our annual maintenance includes:

• Indoor and outdoor coil inspection and cleaning
• Refrigerant level testing
• Electrical component inspection
• Defrost cycle verification
• Drainage system check
• Airflow and static pressure testing

Skipping annual service can lead to:

• Reduced heating output
• Increased electricity costs
• Compressor damage
• Voided manufacturer warranty

We strongly recommend maintenance before heating season begins each fall.

Homeowner Maintenance Responsibilities

Even with professional servicing, certain maintenance tasks must be handled by the homeowner.

1. Snow Removal Around the Outdoor Unit

This is the most common winter issue we see in Ottawa.

After heavy snowfall:

• Clear snow around the unit
• Maintain 12–18 inches of clearance
• Keep the top and front discharge area clear
• Gently remove excessive ice buildup

If airflow is restricted, the heat pump cannot extract heat effectively. This results in poor heating performance and unnecessary service calls.

Membership in a protection plan does not replace the need for timely snow removal.

2. Replace or Clean Air Filters

Filters should be replaced or cleaned every 1–3 months. Restricted airflow reduces efficiency and increases system strain. For larger media filters (4″ or 5″) we recommend changing them every 6 months due to their larger size and capacity.

3. Keep Vents and Returns Clear

Ensure no furniture or coverings block airflow throughout the home.

4. Monitor System Operation

Light frost and periodic defrost cycles are normal. Persistent heavy ice, loud noises, or constant cycling should be inspected.

Protecting Your Heat Pump With Our Family Protection Plans
