Immediate Assessment and System Sizing

When you request a replacement service, the process begins with a technical evaluation of your home’s thermal needs rather than a simple equipment swap. Replacing a heat pump requires more than just reading the model number off the old unit. Building envelopes change over time; new windows, added insulation, or renovations can alter the heating and cooling load of your property. We perform a detailed load calculation to ensure the new equipment is sized perfectly for your current layout.

We inspect the existing ductwork and air handling infrastructure. A new, high-efficiency heat pump cannot perform correctly if the air distribution system is compromised by leaks, blockages, or inadequate sizing. Our team evaluates the static pressure capabilities of your current ducts to ensure they can handle the airflow requirements of modern variable-speed blowers. If you are transitioning from a different heating source to a heat pump, we assess the electrical capacity of your panel to confirm it can support the new amperage requirements.

This initial phase provides you with a clear scope of work. You will receive a detailed proposal outlining the specific equipment recommendations, the efficiency ratings (SEER2 and HSPF2), and a timeline for the installation. We prioritize transparency so you understand exactly what components are being installed and how they will improve your home's energy management.

The Installation Process: What to Expect

A heat pump replacement is a complex construction project involving electrical work, refrigeration, and airflow management. We follow a rigorous, step-by-step protocol to ensure the longevity and efficiency of your new system.

Site Preparation and Protection

• Our technicians arrive with drop cloths and protective gear to ensure your home remains clean throughout the process.
• We disconnect the electrical power to the existing outdoor condenser and indoor air handler to ensure safety.
• Access paths to the furnace room and outdoor unit location are cleared for safe equipment transport.

Refrigerant Recovery and Removal

• Before the old unit can be moved, we must legally and safely recover any remaining refrigerant. Venting refrigerant is illegal and harmful to the environment.
• We use specialized recovery machines to transfer the old coolant into certified reclamation cylinders.
• Once the system is empty, we disconnect the refrigerant lines, high-voltage wiring, and low-voltage control wires.
• The old outdoor unit and indoor coil or air handler are removed and hauled away for proper recycling.

Indoor and Outdoor Equipment Installation

• We position the new indoor air handler or evaporator coil, ensuring a sealed fit with the existing supply and return plenums to prevent air leakage.
• The outdoor unit is placed on a new pad or mounting bracket. In our region, elevating the unit is critical to keep it above potential snow accumulation and allow for proper drainage during defrost cycles.
• We install a new filter drier to trap moisture and debris, protecting the compressor.

Lineset and Electrical Connection

• New copper refrigerant lines are run between the indoor and outdoor units. If reusing existing lines, they are flushed thoroughly to remove contaminants.
• We braze the copper connections using nitrogen purging. This step prevents oxidation inside the pipes, which is a leading cause of premature compressor failure.
• High-voltage electrical whips and disconnect boxes are replaced if they show signs of wear or weather damage.
• Low-voltage thermostat wiring is connected and verified for proper communication between the thermostat and the heat pump.

Vacuum and Charging

• We connect a vacuum pump to the system to remove air and moisture from the lines. We pull a deep vacuum, measured in microns, to ensure the system is completely dry.
• Once the vacuum holds, we release the factory refrigerant charge.
• We fine-tune the refrigerant level based on "subcooling" and "superheat" calculations specific to the length of your lineset and the outdoor temperature.

Final Commissioning and Testing

• The system is powered on and run through a full test cycle in both heating and cooling modes.
• We verify airflow volume to ensure the static pressure is within the manufacturer's specified range.
• We test the defrost cycle functionality to confirm the unit will operate correctly during freezing temperatures.
• Finally, we walk you through the operation of your new thermostat and explain maintenance requirements.

Deciding Between Repair and Full System Replacement

Homeowners often face the difficult choice of sinking money into a repair or investing in a new system. While repair is sometimes a viable option, specific technical indicators suggest that replacement is the more financially sound decision.

The 50% Rule

If the cost of the repair approaches or exceeds 50% of the value of a new system, replacement is the smarter financial move. Major component failures, such as a seized compressor or a leaking reversing valve, often carry repair bills that make retaining the old unit uneconomical.

Refrigerant Type

If your current heat pump utilizes R-22 refrigerant (Freon), it is obsolete. Production of R-22 has ceased, making refills astronomically expensive. If an R-22 system develops a leak, replacement is the only logical path as modern refrigerants cannot be used in R-22 compressors.

Age and Efficiency

Heat pumps generally last 12 to 15 years. If your unit is over 10 years old and facing a repair, its remaining lifespan is likely short. Furthermore, older units have significantly lower HSPF (Heating Seasonal Performance Factor) ratings. Replacing a 10 SEER unit with a modern 18+ SEER2 system can reduce energy consumption by a substantial margin, offsetting the installation cost over time.

Frequency of Breakdowns

System reliability degrades over time. If you have required multiple service calls in the last two years, the system is signaling the end of its service life. "Nickel and diming" repairs often cost more in the long run than a planned replacement.

Comfort Issues

If your current system runs continuously but fails to maintain the set temperature, or if humidity levels in the home are uncontrolled, the compressor valves may be worn out. A new system restores capacity and dehumidification capabilities.

Understanding Local HVAC Requirements

Operating a heat pump in British Columbia requires specific considerations regarding climate, permits, and electrical infrastructure. The Lower Mainland generally has mild winters, but recent years have seen cold snaps that challenge standard heat pumps.

Cold Climate Performance

Standard heat pumps lose heating capacity as the temperature drops below freezing. For our region, we highly recommend "Cold Climate" air source heat pumps. These units utilize variable-speed inverters and enhanced vapor injection technology to maintain 100% heating capacity even when outdoor temperatures drop significantly below zero. This reduces reliance on expensive backup electric heat strips.

Defrost Drainage Management

Heat pumps naturally create condensation and frost on the outdoor coil during winter operation. The unit enters a defrost cycle to melt this ice. In our climate, proper drainage is essential to prevent this water from refreezing on walkways or damaging the unit's base. We ensure all installations account for proper condensate management.

Electrical Panel Capacity

Many older homes in the area have 100-amp electrical panels. Modern heat pumps, especially those with electric backup heating elements, can draw significant power. Upgrading to a 200-amp service may be required to meet code and ensure safe operation. Northwind Heating, Cooling & Fireplace Showroom can help coordinate these electrical assessments during the quote process.

Rebates and Incentives

Our region frequently offers substantial rebates for switching from fossil fuel heating (natural gas or oil) to electric heat pumps. Programs like CleanBC and federal grants often require the installation to be performed by a certified contractor and the equipment to meet specific HSPF and SEER ratings. We guide you through eligible models to maximize your potential savings.

Noise Bylaws

Municipalities often have strict bylaws regarding the decibel levels of outdoor mechanical equipment at the property line. Modern inverter-driven heat pumps are significantly quieter than older single-stage units, helping you stay compliant with local noise regulations while maintaining good neighbor relations.

Technical Expertise and Certified Installation

The performance of a heat pump is determined more by the quality of the installation than the brand of the equipment. A top-tier unit installed poorly will fail prematurely and run inefficiently. We differentiate our services through technical rigor and adherence to best practices in thermodynamics and refrigeration.

Refrigeration Licensing

Our technicians hold valid refrigeration tickets and ozone depletion prevention certifications. Handling high-pressure refrigerant requires specialized training to ensure the system is sealed tight and operates at the correct pressures.

Ductwork Modifications

We do not simply force a new unit onto old ductwork. We fabricate custom sheet metal transitions when necessary to streamline airflow and reduce static pressure. This reduces noise and strain on the blower motor.

Commissioning Reports

We don't guess; we measure. Upon completion, we verify that the temperature rise and drop across the coils match the manufacturer's engineering data. This scientific approach confirms that the unit is delivering the BTU output you paid for.

Ongoing Support

A heat pump requires annual maintenance to keep the warranty valid and efficiency high. We provide clear maintenance schedules and support to keep your investment running smoothly for its entire lifespan.
