If you live in Bellevue, Kirkland, or nearby cities like Redmond or Sammamish, you know how essential it is to have a reliable heating and cooling system. Whether keeping cool during the summer or staying warm during our damp Pacific Northwest winters, your HVAC system works hard year-round. But eventually, every system reaches the end of its life.
This guide will break down how much HVAC replacement costs in the Bellevue or Kirkland areas.
Average HVAC Replacement Cost in Bellevue and Kirkland
The cost to replace an HVAC system in Bellevue, Kirkland, or nearby areas generally ranges between $8,500 to $19,000, depending on several key factors:
| System Type | Average Cost (Installed) |
| Furnace Only | $5,000 – $8,000 |
| AC Only | $5,500 – $9,000 |
| Heat Pump System | $9,000 – $19,000 |
| Full HVAC System (Furnace + AC or Heat Pump) | $11,000 – $18,000 |
Note: These are ballpark figures for the greater Eastside, including HVAC replacement in Redmond, HVAC replacement in Sammamish, and surrounding neighborhoods.
Factors That Affect HVAC Replacement Cost
- Type of System
The cost varies greatly depending on whether you’re replacing a furnace, central air conditioner, heat pump, or the entire system. For Bellevue homeowners looking for high efficiency and year-round comfort, heat pump systems have become increasingly popular—especially with the availability of federal tax credits and PSE rebates.
- System Size & Home Square Footage
HVAC systems are sized according to your home’s square footage and layout. A 1,200 sq ft home may only need a 2-ton system, while a 3,000+ sq ft house might require a 5-ton unit. The larger the system, the more expensive it gets—especially when ductwork modifications are needed.
- Energy Efficiency Ratings
High-efficiency HVAC systems (like those with SEER2 18+ ratings) cost more upfront but can save you thousands in energy bills over time. Many homeowners in Kirkland and Bellevue opt for energy-efficient models because of the long-term value—and our utility rates make those savings add up quickly.
- Ductwork Condition
Old or leaking ducts reduce system performance by as much as 20–30%. If your ductwork is in bad shape, you might need partial or full duct replacement, which can add $2,000–$6,000 to the total cost, depending on the complexity.
- Rebates and Tax Incentives
Here’s the good news: PSE offers generous rebates for qualified HVAC replacements in Bellevue and Kirkland. Plus, the 25C federal tax credit can cover up to $2,000 for eligible systems. Many homeowners offset a significant portion of their installation cost using these incentives.
How to Know It’s Time for HVAC Replacement
If you’re experiencing any of the following signs, it’s likely time to consider AC replacement or a full HVAC system upgrade:
- Your system is 12–20 years old
- Your energy bills keep rising despite maintenance
- Frequent breakdowns or costly HVAC repairs
- Uneven heating or cooling throughout the house
- Loud noises, unusual smells, or humidity issues
- You’re investing in home improvements or remodeling
For residents in Kirkland, Bellevue, Redmond, and nearby areas, our moist climate also means your system works harder than it might in drier regions—accelerating wear and tear.
Should You Repair or Replace?
We get this question a lot. At TemperaturePro Kirkland, our team always weighs the cost of repair versus replacement. A good rule of thumb is:
- If repair costs exceed 50% of a new system, and your current system is over 10 years old, replacement is usually the smarter investment.
- Additionally, AC repair in Bellevue or HVAC repair in Kirkland can be an effective solution for minor issues, but they won’t solve problems caused by aging components, outdated efficiency standards, or improperly sized systems.

Tips to Save on HVAC Replacement Costs
- Schedule a Spring or Fall Installation: You’ll often get better pricing during slower seasons—before summer heat or winter chill ramps up demand.
- Look for Financing Options: Many local HVAC companies offer 0% financing, which allows you to spread out the cost without interest.
- Bundle Services: If you’re also upgrading your electrical panel or adding insulation, bundling those projects can often reduce total labor costs.
- Choose the Right Size (Not the Biggest): Oversized systems short cycle, which wastes energy and wears down components faster. Correct sizing saves money.
- Use Local Rebates: Residents in Kirkland, Sammamish, Bellevue, and Redmond may be eligible for PSE rebates and federal tax credits that save $2,000 or more on qualifying heat pumps.
HVAC Replacement FAQs
Q: How long does an HVAC installation take?
A: Most replacements take 1 to 2 days, depending on system complexity and any duct or electrical work involved.
Q: Can I replace just the AC or furnace?
A: You can, but mismatched components can reduce efficiency and shorten lifespan. If both units are over 10 years old, we recommend replacing them together.
Q: What brands do you install?
A: At TemperaturePro, we install leading brands like Daikin, Goodman, and American Standard—each backed by solid warranties.
Final Thoughts: Investing in Comfort and Efficiency
Replacing your HVAC system is a big investment, but it pays off in the form of increased comfort, lower energy bills, and peace of mind. If you’re living in Kirkland, Bellevue, or anywhere across the Eastside, your HVAC system faces a unique climate challenge—moisture, cold winters, and warm (increasingly hot) summers.
That’s why choosing an experienced HVAC company with local expertise makes a difference.
