Frequently Asked Questions

When considering furnace installation or replacement costs, it’s essential to understand the various factors that can influence the final price. Here’s a breakdown of typical costs and the factors that affect them:

Average Installation Cost: The average for a full furnace installation ranges from $4,820 to $9,350. This includes the cost of the furnace itself, labor fees, ductwork, removal, and disposal of the old furnace, as well as other installation costs or upgrades included.

Type of Furnace: The type of furnace you choose significantly impacts the installation cost. Here’s a breakdown of average installation costs for different types of furnaces:

  • Electric Furnace: Typically ranges from $1,800 to $7,300, depending on factors such as size and efficiency. Electric furnaces are suitable for regions with mild winters and are measured in kilowatts.
  • Natural Gas Furnace: Ranges from $2,800 to $9,500 for the average installation cost. High-efficiency models may cost more initially but offer long-term savings on utility costs. Natural gas furnaces are ideal for colder climates.
  • Oil Furnace: Common in regions with harsh winters, oil furnace installation costs typically range from $4,500 to $8,000 or higher. Oil furnaces require more maintenance but can have a longer lifespan.

Size and BTU Capacity: The size of the furnace is determined by the British Thermal Units (BTUs) required to heat your home. The cost of a furnace is influenced by its BTU capacity, with larger units costing more. The BTU requirement is calculated based on the square footage of your home, typically around 40 BTUs per square foot. Additional factors such as cathedral ceilings or drafty windows may require adjustments to the BTU calculation.

Installation vs. Replacement: Whether you’re installing a new furnace or replacing an existing one also affects the overall cost. Replacing an old furnace with a new one may be more cost-effective as existing infrastructure can be utilized. However, converting from one type of furnace to another or relocating the furnace may require additional work and incur higher costs.

Additional Installation Considerations: Factors such as ductwork requirements, location changes, and any necessary upgrades or modifications to accommodate the new furnace also contribute to the overall installation cost. HVAC duct installation typically costs between $10 and $20 per linear foot.

The time it takes to install a new A/C system in your home can vary depending on several factors, including the complexity of the installation, the size of the unit, and whether other HVAC components are being replaced simultaneously. Here’s what you can typically expect:

  1. Replacement Only: If you’re solely replacing the air conditioning unit, the installation process typically takes between 4 to 8 hours on average. Our experienced technicians at Mainstream are trained to work efficiently while ensuring the highest quality installation standards.
  2. Replacement of Furnace and A/C: If you’re upgrading both your furnace and air conditioning unit concurrently, the installation timeline may extend to between 8 to 14 hours. This is because the installation involves additional steps such as removing and replacing both systems, ensuring compatibility, and making necessary adjustments for optimal performance.

Selecting the correct size air conditioner is crucial for optimal comfort, performance, and energy efficiency in your home. When you work with the professionals at Mainstream, here are some pointers so you can ensure you are getting the right choice:

  1. Calculate Cooling Capacity: Use a rule of thumb that suggests around 20 BTUs per square foot of space to estimate the cooling capacity you need. Multiply the room’s square footage by 20 to get a basic estimate of the required cooling capacity. However, keep in mind that this is just a starting point and may vary depending on factors such as insulation, ceiling height, and local climate conditions.
  2. Avoid Oversizing or Undersizing: An air conditioner that is too large for your home will lead to excessive energy consumption, higher utility bills, and increased wear and tear on the system. Conversely, an undersized unit will struggle to cool your home effectively and may result in inadequate comfort levels.
  3. Professional Assessment: While rule-of-thumb calculations can provide a rough estimate, we will consider various factors such as the layout of your home, insulation levels, and local climate to recommend the appropriate size air conditioner for your specific needs.
  4. Efficiency and Cost Considerations: Investing in the right-sized air conditioner not only ensures comfort but also helps you save on energy costs in the long run. An efficiently sized unit will operate more effectively, reducing energy waste and lowering your utility bills.
  5. Long-Term Benefits: By choosing the right size air conditioner, you can avoid common issues associated with improperly sized units, such as inadequate cooling, excessive energy consumption, and premature system failure. This ensures that your HVAC system runs efficiently and reliably for years to come.
  6. Mainstream’s Expertise: At Mainstream, we understand the importance of selecting the right HVAC system for your home. Our team of experienced technicians is here to assist you every step of the way, from sizing recommendations to professional installation, ensuring that you enjoy optimal comfort and efficiency.

When you make a big, long-lasting purchase like a furnace for your home, you want to be informed. The different types of furnaces are suited to different homes, climates, and lifestyles. Mainstream will help you decide between electric, gas, and oil, what size of furnace you need, and what brand is best.

If you’re experiencing issues with an existing furnace, we can help you answer that question! You may just need furnace repairs. Even if you’re considering a new furnace because your current one isn’t getting the house warm enough, you may just need a furnace tune-up to help it heat better.

The 3 main types of new furnace installations available are:

Gas Furnaces

Gas furnaces are the most commonly installed furnaces in Spokane homes.

More efficient than installed oil furnaces, but less than electric, gas furnaces are typically the cheapest to run, as they use natural gas as an energy source. With this, your home runs the risk of creating a buildup of carbon monoxide, and your furnace will require on-going maintenance throughout its life.

Gas furnaces are, however, the least expensive model to run using natural gas, making them a favorable choice for furnace replacement.

Electric Furnaces

The electric furnace is another popular choice for homeowners. Electric furnace installations are less expensive, as they require only electricity and not natural gas line piping installation or oil storage tanks.

On the flip-side, electrical furnaces are the most expensive to run due to their high usage of electricity. Electric furnaces still remain a common furnace replacement option with their comparatively lower purchase costs & minimal lifespan maintenance.

Oil Furnaces

Oil furnaces are not what they once were in Spokane, but they still offer some attractive benefits. Oil furnaces are able to heat large spaces evenly & have less emissions than gas furnaces, with no risk of carbon monoxide leakage in your home.

However, oil furnaces do require an on-site oil storage tank for fuel & an oil delivery service. Oil is typically more expensive than natural gas and has the lowest efficiency rating for heating per its energy source.

No matter the problem, our furnace installation technicians will determine your heating & furnace needs and finances before any work is done, so you will know what solution is best & most affordable for your new furnace system.

Your furnace is a large, complex unit that will deliver years of exceptional heating to your entire home. It is important that it’s installed correctly, otherwise this costly investment can go to waste.

Multiple factors determine the overall cost of a new furnace installation, but the type of furnace you choose has the largest impact. Our expert HVAC technicians at Mainstream Electric, Heating, Cooling, & Plumbing will help you find the perfect furnace to install that’s best for your Spokane Valley, Washington home.

There’s no getting around the fact that a new furnace is a relatively expensive purchase! Depending on any number of factors like size, energy efficiency, and style, a furnace can cost as little as $1,500 and up to several thousand dollars.

That’s why, at Mainstream, we offer a new furnace installation financing plan: pay $0 down and as low as $89 a month!
