Why Heat Pump Replacement Matters in Sammamish

Sammamish experiences cool, wet winters and mild summers. Heating demand is a major portion of household energy use. Inefficient or aging equipment increases energy costs.

Modern heat pumps provide:

• Reliable year-round heating and cooling
• Lower operating costs than older heat pumps or electric resistance systems
• Improved indoor comfort, humidity control, and reduced noise
• Increased home value and reduced carbon footprint

Proper sizing and installation are crucial due to local microclimates, tree cover, and proximity to Lake Washington.

Common Signs It’s Time to Replace Your Heat Pump

Replacement may be more cost-effective than repeated repairs if you notice:

• Age of system: Most units last 10–15 years; efficiency drops after 12 years
• Repeated failures: Frequent compressor, reversing valve, or refrigerant leaks
• Rising energy bills: Higher costs despite unchanged usage
• Insufficient heating: Struggles to maintain comfort on cold nights
• Noisy operation: Worn compressors, loose parts, or degraded mounts
• Frequent defrost cycles: Excessive frosting or defrosting
• Duct compatibility problems: Persistent airflow issues or high duct losses
• R-22 refrigerant or obsolete parts: Phased-out refrigerants or unavailable replacement parts

How Greenhead Heating Evaluates Your System

A professional evaluation ensures repair or replacement decisions are data-driven:

Visual and Operational Inspection

• Outdoor unit, indoor coil, air handler, ductwork, and controls
• Listen for unusual noises and measure indoor/outdoor temperatures

Performance Measurements

• Supply and return air temperatures, superheat/subcooling, refrigerant pressures
• Compare airflow to manufacturer specs

Electrical & Mechanical Diagnostics

• Inspect electrical connections, capacitors, contactors, reversing valves
• Test compressors and motors for stress or impending failure

Efficiency & Cost Analysis

• Estimate SEER and HSPF using current performance and age degradation
• Provide modeled annual energy use and operating cost

Duct & Envelope Review

• Inspect duct leakage, insulation, and register performance
• Evaluate attic, crawlspace, and window conditions affecting load

Recommendation & Options

• Offer repair vs replacement guidance
• Project payback, comfort benefits, and list suitable replacement options

Replacement Options for Sammamish Homes

High-Efficiency Air-Source Heat Pumps

• Ideal for homes with existing ductwork
• Efficient heating at lower outdoor temps
• Look for higher SEER and HSPF for long-term savings

Cold-Climate Air-Source Heat Pumps

• Maintain heating capacity in sub-freezing conditions
• Minimal reliance on backup heat

Ductless Mini-Split Systems

• For homes without ducts or room additions
• Flexible zoning, high efficiency, minimal installation disruption

Multi-Zone Systems

• Single outdoor unit with multiple indoor heads
• Efficiently heats/cools distinct areas

Geothermal Heat Pumps

• Stable year-round performance using ground temperature
• Higher upfront cost, lower operating cost over time

Hybrid Systems

• Combines heat pump with gas furnace for low temperatures
• Automatically switches to most economical mode

Equipment Selection Considerations

• Correct sizing: Avoid short-cycling or undersizing
• Matching indoor/outdoor components
• Controls and zoning: Smart thermostats improve efficiency
• Noise and aesthetics: Compact, quieter units

Cost and Savings Projections

Upfront Costs

• Equipment type and capacity affect cost
• Installation complexity: duct modifications, electrical upgrades, line routing
• Permits and disposal fees

Operating Cost Savings

• Modern heat pumps reduce heating costs by 20–50% vs older electric resistance systems
• New high-efficiency units reduce energy use 10–30% compared to 10–15-year-old air-source pumps

Removal & Disposal of Old Equipment

• Refrigerant Recovery: Technicians recover refrigerant per regulations
• Environmental Disposal: Metals, plastics, and electronics recycled; hazardous materials handled safely
• Site Cleanup: Pads, mounting hardware, and debris removed
• Documentation: Provided for rebate applications and records

Installation Process & Timeline

Process Steps

1. Pre-installation planning: load calculation, site plan, equipment selection
2. Permit acquisition and scheduling inspections
3. Removal of old equipment
4. Prep and ductwork adjustments
5. Equipment installation: outdoor unit, air handler, refrigerant lines, controls
6. Commissioning: refrigerant charge, airflow calibration, system testing
7. Final inspection & homeowner orientation

Typical Timeline

• Simple like-for-like: 1–2 days
• Duct modifications, electrical upgrades, multi-zone: several days–1 week

FAQs

Q: How do I know whether to repair or replace?
A: Evaluate age, repair frequency, efficiency, and remaining life. Replacement is typically better if the system is 10–12+ years old, frequently breaks down, uses phased-out refrigerants, or shows rising energy bills.

Q: What heat pumps work best in Sammamish?
A: Modern air-source and cold-climate heat pumps. Cold-climate models maintain performance in sub-freezing temperatures. Ductless systems work well for room additions or homes without ducts.

Q: How long does replacement take?
A: Simple replacements: 1–2 days. Ductwork changes, electrical upgrades, zoning, or geothermal loops: several days to weeks. Permits may extend timelines.

Q: Are permits required?
A: Yes, most projects require local permits and inspections. Greenhead Heating coordinates this.

Q: Typical warranty coverage?
A: Manufacturer: ~10 years on major components; installer: defined period for workmanship. Proper documentation ensures validity.

Q: Are rebates or tax credits available?
A: Yes—utility, state, and federal programs exist; Greenhead Heating provides estimates in proposals.
