Superior HVAC installation Replacement Gig Harbor by Infinity Heating & Air. Experience peak performance and lasting comfort. Call us today to get started.


Your home's heating, ventilation, and air conditioning (HVAC) system is the heart of your indoor comfort. It works silently behind the scenes to keep you warm during chilly Pacific Northwest winters and cool on those rare, beautiful sunny days. When it's time for a new system, whether due to a sudden breakdown or a planned upgrade, the quality of the installation is just as important as the quality of the unit itself. A professional installation ensures your system operates safely, efficiently, and reliably for years to come, providing the year-round comfort your Harbor home deserves.
At Infinity Heating & Air, we specialize in the complete installation and replacement of residential HVAC systems. Our process is built on precision, expertise, and a deep understanding of the unique climate challenges and housing styles in the Harbor, WA area. We don’t just swap out boxes—we engineer a complete comfort solution tailored to your home’s specific needs.
Installing a new HVAC system is a significant investment. A subpar installation can negate the benefits of even the most advanced, high-efficiency equipment, leading to higher energy bills, frequent breakdowns, and a shorter lifespan for your unit.
One of the most common mistakes in HVAC replacement is incorrect sizing. A system that’s too large will cycle on and off frequently, failing to adequately dehumidify your home and causing unnecessary wear and tear. A system that’s too small will run constantly, struggling to reach the desired temperature and driving up energy costs. Our technicians perform detailed load calculations based on your home’s square footage, insulation, window layout, and other critical factors to determine the precise size your home requires for optimal performance.
A new furnace, air conditioner, or heat pump must be perfectly integrated with your existing infrastructure, including ductwork, electrical circuits, and ventilation. Infinity Heating & Air meticulously inspects and adapts these components to ensure they can support your new system, guaranteeing balanced airflow, safe operation, and peak efficiency from day one.
We provide expert installation for a wide range of modern heating and cooling systems, helping you find the perfect match for your budget, efficiency goals, and lifestyle.
Modern furnaces are far more efficient than models from just a decade ago. We install both natural gas and electric furnaces, focusing on models with high AFUE (Annual Fuel Utilization Efficiency) ratings. A new high-efficiency furnace can significantly reduce your winter heating bills while providing consistent, powerful warmth throughout your home. Our team ensures your furnace is vented properly and calibrated for a safe, reliable heat source.
Stay cool and comfortable all summer with a new central air conditioning system. We install high-SEER (Seasonal Energy Efficiency Ratio) units that use less energy to cool your home, translating directly into lower utility costs. Our installation process focuses on correct refrigerant charging and airflow balancing to maximize cooling power and dehumidification, creating a refreshing indoor oasis.
Heat pumps are an increasingly popular choice in Harbor for their incredible versatility and efficiency. This single system provides both heating and cooling by moving heat rather than creating it. In summer, it pulls heat out of your home; in winter, it extracts heat from the outside air to warm your home. Heat pumps are exceptionally energy-efficient, making them an excellent choice for homeowners looking to reduce their carbon footprint and energy expenses.
Your ductwork is the circulatory system of your HVAC. Leaky, poorly designed, or undersized ducts can lose up to 30% of conditioned air before it reaches the vents. Infinity Heating & Air offers comprehensive ductwork services—from sealing and repair to complete replacement—ensuring the warm or cool air you’re paying for is delivered exactly where it’s needed.
It can be difficult to know when a simple repair is no longer enough. If you notice any of the following signs, it may be more cost-effective in the long run to invest in a full system replacement:
