Amazed

Our home is 66 years young and it was time to replace the original water lines and sewer lines. I was amazed that they were able to streamline, fix old plumbing mistakes and make our entire water system user friendly. Thank you Cody, Donovan and the third guy that I can't remember his name. They were all professional, polite and knowledgeable.

Best service

Crew was very efficient and knowledgeable. Replaced HVAC with next day service for first responders. System is working well and installed superbly. Will give it a run for a while to better judge but it is a quality name Lennox system. 10 year parts and service so expect there will be no problems. Good job!

Highly Recommend

Highly Recommended- My first time using this company for the water heater flush special for $99. Good value. The serviceman Brent was knowledgeable, very professional and courteous. He explained things well. He was friendly and used shoe covers and face mask, even though I didn’t require it. I appreciated the good service and clean work. I also received a follow up phone call from their office after the work was done.

Knowledgeable

I had Mainstream come out for an annual inspection of my hot water heater. After the inspection, it was determined that the water heater needs to be replaced. The technician, Cory, was very professional and made all of the necessary arrangements. Later the same day, Shane came out and replaced the water heater. Shane was very professional and knowledgeable. I am very pleased with the employees and the work that was completed by Mainstream.
Dan S.

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.

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.
