How Much Does a New Furnace Installation Cost In WA?

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.

The 3 main types of new furnace installations available are:

Gas Furnace Installation & Replacement

Gas furnaces are the most commonly installed furnaces in Spokane Valley 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 Furnace Installation & Replacement

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.

Ask an HVAC expert from Mainstream Electric, Heating, Cooling, & Plumbing today if the cost of an electric furnace installation is worthwhile for your home.

Oil Furnace Installation & Replacement

Oil furnaces are not what they once were in Spokane Valley, Washington, 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, however, this depends largely on your Spokane Valley, Washington location.

Call us today to schedule a furnace installation cost estimation to see if an oil furnace installation is the right fit for your home.

No matter the problem, our Spokane Valley, Washington 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.

These guys are amazing!!!

Our heater went out in Dec. My mother in law was visiting for holidays, They came within hours, presented us with options and then brought electric heaters for us to use until the work was finished. They were fast, friendly, professional, just all around Amazing. Everyone from the very beginning. Thank u so much mainstream for saving our Christmas and getting our heating system replaced so fast.

The guys were great

They were respectful of our furnishings they needed to move and put them back carefully. They were mindful of our pets so they were secure and not frightened by the loud vacuum used to clean the vents. Super nice guys, definitely recommend Mainstream. They've been nothing but professional and responsive since the minute we called them with a failing furnace at the end of the year. Thank you Mainstream.

Knowledgeable, fast and efficient!

Norm and Adam were knowledgeable, fast and efficient when installing my new furnace. They had answers to all of my questions and explained everything they were doing. I would recommend Mainstream Electric to anyone needing help with their heating. They even assisted me in getting financing for my furnace. Thanks to everyone at Mainstream Electric you are great!

Very Happy

We had them come out for a yearly maintenance on our water heater. They were thorough and gave good recommendations for continued maintenance and use. We also had them install a new furnace and air conditioning unit. They were very quick and efficient. All the crew members were courteous and respectful of our home. I am very happy to recommend them to others.
