Frequently Asked Questions

You should have your unit maintained once a year to keep it running at peak performance.

Our team at Mainstream is happy to service your home furnace and provide the locally-rated, top-quality work and customer service your neighbors have been talking about. Call us at (866) 460-3772 today!

A lot of people neglect their furnace until it stops working, but an annual tune up of your home furnace can keep it in top shape for years to come. When it is not maintained, it has to work much harder to put out the same amount of heat, causing your furnace to burn out faster.

Your furnace and home will benefit greatly from a routine tune-up, and we are here to provide you with a detailed diagnostic report of anything we find. By having a professional take a look at your furnace, you can increase its lifespan, prevent damage, and avoid an early replacement.

Furnace maintenance is a service in which your furnace is professionally cleaned and maintained. Routine maintenance ensures that your unit runs at peak performance for as long as possible and avoids unnecessary breakdowns.

During a furnace maintenance appointment, our professional technicians will inspect your home’s furnace to ensure that all parts are safe and working properly. They will also be able to quickly identify and fix any issues before they can turn into costly repairs.

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!
