When to Repair vs. Replace Your Heat Pump: A Burnaby Owner's Decision Guide

The Quick Answer for Burnaby Homeowners

If your heat pump is under 8 years old and the repair is under $1,500, fix it.

If it is over 12 years old and the repair touches the compressor, refrigerant circuit, or reversing valve, start planning a replacement now - even if the tech says they can patch it.

Everything between those two endpoints is a judgment call, and the right call depends on three factors most quotes do not surface: refrigerant type, the cost of the next failure, and whether your heat pump installation is still under any warranty coverage.

This post is the framework we use when a Burnaby homeowner asks us, on the spot, whether the unit in their backyard is worth saving.

Why the “50% Rule” Misses the Mark

You will see the 50% rule everywhere online: if a single repair costs more than half of a replacement, replace.

It is a useful rough cut, but it leaves out the four factors that actually drive the math:

• How many more repairs are likely in the next 24 months
• What refrigerant the system uses and whether it is being phased out
• How efficiency drift affects your monthly bill
• Whether you qualify for current 2026 rebates that change the replacement cost

A $2,400 compressor repair on a 14-year-old R-410A heat pump may pencil out under the 50% rule. But if that same unit needs another major repair within 18 months, and the refrigerant is becoming harder to source, the “repair is cheaper” case collapses fast.

The Three-Tier Burnaby Decision Framework

Use these three filters in order. The first filter that flags is your answer.

Tier 1: Age

Heat Pump Age	Default Recommendation
0 - 8 years	Repair almost always wins
9 - 12 years	Run the full math
13+ years	Replacement almost always wins

Most Burnaby heat pumps installed during the post-2010 retrofit wave are now in the 9-to-14 year band. That is the band where the decision actually matters - and where most homeowners default to repair because the upfront cost is smaller, not because the long-term math agrees.

Tier 2: Refrigerant Type

BC has been quietly transitioning away from R-410A since 2024. Most new residential heat pumps now ship with R-454B or R-32. The transition matters for repair decisions in two ways:

• R-410A is still legal and available, but the price per pound has roughly tripled since 2022 and continues to rise as production winds down.
• A leak repair on an R-410A system is more expensive every year - both for the refrigerant itself and because fewer techs want to source it for marginal work.

If your heat pump uses R-22, the answer is replacement. R-22 has been phased out for new equipment since 2010 and is now prohibitively expensive when you can find it at all.

Tier 3: Component Class

Repairs cluster into three failure classes:

• Class A (low-stakes): capacitors, contactors, fan motors, control boards, thermostats. Usually $200 - $700 installed. Repair almost always wins regardless of system age.
• Class B (mid-stakes): reversing valve, expansion valve, defrost board, condensate pump. $700 - $1,800 installed. Decision depends on age and refrigerant.
• Class C (high-stakes): compressor, evaporator coil leak, condenser coil leak, refrigerant circuit. $1,800 - $4,500+ installed. On a system over 10 years old, this is almost always a replacement signal.

The Total-Cost-of-Ownership Math

Here is a real example from a Brentwood-area Burnaby client this past spring:

• 2012-vintage 3-ton heat pump (14 years old)
• R-410A refrigerant
• Failure: refrigerant leak in the indoor evaporator coil
• Repair quote: $2,800 (coil + refrigerant recharge)
• Replacement quote: $11,500 (cold-climate variable-speed unit)

The 50% rule said repair. The full math said replace.

Why?

• The new unit qualified for $4,500 in stacked CleanBC and BC Hydro rebates, dropping net cost to $7,000.
• The repair was buying maybe 24 months on a system that had already had two prior service calls.
• The replacement runs at SEER2 18+ versus the original SEER 13. On a Burnaby home with 2,400 sq ft, that is roughly $400/year in operating-cost savings.
• R-454B refrigerant supply is stable and significantly cheaper to top off if needed.

Net cost of repair over a realistic 24-month horizon (including likely follow-up repairs): about $4,500.

Net cost of replacement over the same horizon: about $7,000 minus $800 in efficiency savings = $6,200.

The replacement was $1,700 more over two years - and bought 12 to 15 more years of service.

Repairs That Almost Always Make Sense

Even on older units, a few repairs are usually worth doing:

• Capacitor replacement on any unit
• Contactor replacement on any unit
• Fan motor on a unit under 10 years old
• Thermostat replacement at any age
• Drain pan or condensate pump on any unit
• Outdoor fan blade replacement on any unit

These are quick, cheap, and rarely cascading. If a Burnaby tech says you need one of these on an otherwise-functional system, it is almost always the right move regardless of age.

Repairs That Almost Never Do (on 12+ Year Units)

• Compressor replacement
• Coil replacement (indoor or outdoor)
• Reversing valve replacement
• Major refrigerant circuit repair
• Multiple-component repairs in one visit

Each of these is a strong replacement signal on a 12+ year unit. Combined with R-410A refrigerant and you are paying premium prices to extend the life of a system that is statistically due for the next failure inside two years.

The Burnaby Microclimate Factor

Burnaby is one of the easier microclimates in the Lower Mainland for heat pumps - moderate winters, no salt air, lower wildfire-smoke days than the Fraser Valley. That tends to extend equipment life slightly relative to the regional average.

That said, three Burnaby-specific factors do affect the decision:

• Burnaby Mountain homes see colder winter temperatures than lower-elevation neighbourhoods. A unit at 350m elevation works harder in heating mode than the same unit in Metrotown. That accelerates wear on the reversing valve and compressor.
• Older South Burnaby neighbourhoods (Edmonds, Big Bend) often have undersized electrical service, which makes a like-for-like swap simpler than upsizing - that pushes some replacement decisions toward matched-capacity rather than upgraded systems.
• Brentwood and Lougheed condo conversions occasionally have shared mechanical rooms with strata-restricted equipment lists. Replacement is more constrained but the math is still cleaner than ongoing repair.

What to Ask Before You Sign the Repair Invoice

If a tech is recommending a repair on a 9+ year unit, ask:

1. What is the system’s refrigerant type, and what does that refrigerant cost per pound today?
2. What is the most likely next failure on this system in the next 24 months?
3. What rebates apply if I replace instead, and what is the all-in net cost?
4. If I do this repair, is there anything else you saw today that we should plan to address in the next year?

Honest answers to these four questions are the difference between a smart repair and a stalling repair. We give straight answers because we lose the customer for life if the patched-up system dies eight months later and we did not warn them.

Replacement Timing for Burnaby Homeowners

If the math points to replacement, three timing factors matter in 2026:

• Rebate budgets reset April 1 each year. Income-qualified top-ups can run out by late fall in high-demand years.
• Equipment lead times tighten July through September. Booking in spring is typically the smoothest path.
• Refrigerant transitions are still settling. R-454B is the safer long-term choice and is now standard inventory across all major brands.

If your current unit is limping but functional, a planned replacement in the next rebate window will typically beat an emergency replacement during a heat wave on every dimension - cost, equipment selection, and rebate capture.

Bottom Line

The repair-or-replace decision is rarely about the single quote in front of you. It is about the trajectory of the system: age, refrigerant, and the type of failure you are looking at.

For Burnaby homes:

• Under 8 years and Class A or B repair - repair
• 9 to 12 years, R-410A, Class B repair - run the math, often replace
• 12+ years, any Class C repair - replace
• R-22 refrigerant at any age - replace

If you want a straight read on your specific unit, we are happy to come look at it. We will quote both the repair and the replacement, and tell you honestly which one we would do if it were our own home.
