HVAC Installation in Kirkland

Installing a new heating, ventilation, and air conditioning system is a major investment for any Kirkland homeowner. With damp Pacific Northwest winters, warm summers, and humidity concerns, a properly designed HVAC installation can dramatically improve comfort, reduce energy bills, and protect your home from moisture-related issues. Green Head Heating delivers complete, code-compliant HVAC installation services in Kirkland with a focus on accurate load calculations, correct equipment sizing, and long-term system reliability.

Why Professional Installation Matters in Kirkland

Kirkland homes face unique climate challenges—elevated humidity, lake-effect temperature swings, and an increasing shift toward high-efficiency and electric systems. Correct HVAC design is essential. Improper sizing, poor airflow, or incorrect refrigerant charge can lead to:

• Uneven temperatures
• High energy bills
• Excess humidity and condensation
• Mold growth
• Premature system failure

A properly engineered installation ensures performance, indoor air quality, and compliance with Washington State and City of Kirkland requirements.

Common HVAC Installations in Kirkland

Green Head Heating installs a wide range of systems tailored to local needs, including:

• New central forced-air heating and cooling systems
• Ductless mini-split systems for older homes, additions, and zone control
• High-efficiency heat pumps and cold-climate systems
• Hybrid heat pump + gas furnace combinations
• Duct redesign, replacement, sealing, and efficiency upgrades
• Whole-home ventilation, filtration, and humidity control (ERV/HRV, dehumidifiers)
• Smart thermostats, zoning, and advanced comfort controls

Initial Site Assessment & Load Calculations

Every installation begins with a detailed assessment based on industry-standard load calculation methods.

What we evaluate

• Home size, layout, orientation, and levels
• Insulation quality and building envelope
• Window type and air leakage
• Existing ductwork condition and routing
• Comfort issues and hot/cold rooms
• Local climate factors and moisture concerns

Sizing Methodology

• Manual J for room-by-room heating & cooling loads
• Manual D for duct sizing, airflow balancing, and distribution
• Manual S for matching equipment to the calculated load

This process ensures the system is neither oversized nor undersized—both of which can lead to efficiency and comfort problems.
