- Loud noises during operation
- Uneven heating between rooms
- A furnace older than 10+ years
- Excess humidity, dust, or poor air quality

Find the Right System
Exploring Furnace Options
In Olympia, where we have a distinct heating season, choosing the right furnace is essential for maintaining long-term comfort, efficiency, and reliability. At Harts, we help homeowners compare today’s leading heating technologies—including gas, electric, dual-fuel, and high-efficiency systems—so you can select the ideal match for your home, budget, and climate.
Furnace Replacement
If your current unit is failing or expensive to repair, replacing it with a modern system often costs less over time. We handle:
- Old system removal
- New furnace installation
- Ductwork updates (if needed)
- Thermostat upgrades
- Start-up and performance testing
Many Olympia homeowners save money immediately through improved efficiency.
High-Efficiency
High-efficiency furnaces are engineered to deliver maximum heat using far less energy than older systems. With AFUE ratings up to 98 percent, they convert nearly all fuel into usable warmth, reducing energy waste during Olympia’s long cold season. These systems feature advanced burners, sealed combustion, and variable-speed blower motors that maintain steadier temperatures with lower operating costs. For homeowners seeking the best combination of comfort and savings, high-efficiency models offer long-term value and outstanding performance.
Gas Furnace
Gas furnaces are a powerful and reliable heating option for Olympia homes, providing strong, consistent heat even during the coldest months. They are ideal for households with natural gas access and offer excellent energy efficiency compared to older oil or electric systems. Modern gas furnaces include safety features, quiet operation, and compatibility with advanced airflow components. Harts installs properly sized gas furnaces designed to match your home’s heating requirements and maximize seasonal performance.
Electric Furnace
Electric furnaces are a clean, dependable option for homes without natural gas service. They are known for their lower upfront cost, simpler installation, and minimal maintenance requirements. While they generally cost more to operate than gas systems, electric furnaces offer even heat, quiet performance, and long service life. For smaller spaces, accessory dwelling units, or all-electric homes, an electric furnace can be an efficient and safe heating solution.
Dual-Fuel
Dual-fuel heating systems combine the efficiency of a heat pump with the strength of a gas furnace, giving Olympia homeowners the best of both worlds. The heat pump handles mild-weather heating at extremely low cost, while the gas furnace automatically takes over during colder temperatures. This hybrid approach maximizes comfort, improves energy efficiency, and lowers overall utility costs. Dual-fuel systems are ideal for families seeking consistent performance and long-term savings throughout varying Pacific Northwest weather patterns.
Heat Pump Integration
Integrating a heat pump with an existing furnace provides highly efficient heating during Olympia’s milder fall and spring seasons. Heat pumps extract warmth from outdoor air, using far less energy than traditional electric resistance heating. When temperatures drop, your furnace steps in to provide additional heat. This combined setup significantly reduces operating costs and enhances comfort all year. Heat pump integration is an excellent option for homeowners upgrading from older electric heaters or looking to modernize an existing system.
Variable-Speed & Two-Stage Furnaces
Variable-speed and two-stage furnaces offer precise temperature control and smoother, quieter operation. Instead of constantly turning on and off like a single-stage furnace, these models adjust output based on your home’s real-time heating needs. This reduces energy consumption, eliminates temperature swings, and improves indoor air quality. In Olympia’s cool climate, variable-speed technology delivers an exceptional balance of comfort and efficiency while helping prolong the life of the system.

Cost of Installation
One of the most common questions is, “What is the furnace installation cost?” The truth is, the price varies widely based on several factors, but Harts provides a transparent, all-in quote.
Factor Affecting Pricing:
Type of Furnace
Gas, electric, or dual-fuel, as well as the AFUE efficiency rating.
System Size
The capacity (BTUs) required to heat your home.
Location and Access
The physical location of your furnace in your Olympia home directly impacts the complexity and labor involved.
Ease of Access: An installation in an easily accessible garage or utility closet is typically straightforward, requiring less time and labor.
Limited Access: Locations like a tight crawlspace or a restrictive basement may require specialized equipment, extra safety precautions, or more time to maneuver the old and new units, which can increase the cost.
Complexity and Modifications
Replacing an old furnace with a similar model often keeps costs down. However, specific situations require modifications to your home’s infrastructure:
Ductwork Modifications: Installing a higher-efficiency unit may require adjustments to your existing ductwork to handle the new airflow and ensure balanced heating across your home.
Venting or Gas Line Changes: Upgrading from an older, low-efficiency model often means installing new, specialized venting (like PVC pipes) or upgrading the gas lines to meet current codes and the needs of the new furnace, adding to the total project scope.
Fuel Conversion: Switching from oil or electric heat to a gas furnace installation is a complex job that requires installing new gas lines and flues, which will significantly increase the cost.
Furnace Brand and Features
The cost is directly tied to the brand reputation, the materials used, and the technology packed inside the unit.
Why Brand Affects Cost: Established, high-quality brands often have a higher upfront cost due to superior components, better reliability ratings, and longer manufacturer warranties. They invest more in research and development to produce quiet, highly durable, and efficient furnaces.
Premium Features: Features like variable speed motors (which precisely control airflow), multi-stage burners (which adjust heat output based on conditions), or advanced smart thermostats will increase the initial purchase price but often lead to superior comfort, quieter operation, and significantly greater energy efficiency over the unit’s lifespan.
Current Promotions
Harts provides seasonal promotions to help Olympia homeowners save even more on furnace installation and whole-home comfort upgrades. Whether it’s a discount on high-efficiency systems or bundled savings with additional HVAC services, our team ensures you receive the best available offer. Ask about current promotions when scheduling your consultation so you never miss an opportunity to save.
Rebates & Tax Incentives
You may qualify for valuable savings through local utility rebates, state energy programs, or federal tax incentives. We help identify which furnace models meet rebate requirements and provide documentation to make the process as easy as possible. From Puget Sound Energy rebates to federal energy-efficiency tax credits, Harts makes sure you take advantage of every available incentive for maximum long-term value.
