Furnace Replacement

Sometimes a repair is not sufficient to fix your furnace. Sometimes a new furnace is the most cost-effective and energy-efficient way to go. We will always be honest with you about a possible furnace replacement. We value our time and your money––we don’t want to perform repairs or service on an appliance that is in need of replacement.

If you do need a furnace replacement, we know how overwhelming it can be. Here are some of the frequently asked questions about furnaces that we get from some of our Seattle, WA residents:

What Are The Different Types Of Furnaces?

Single Stage: A single-stage furnace has only one stage of operation. It can either be turned on or turned off.

Two Stage: A two-stage furnace has two settings––full and half speed. This is a more efficient way to heat and provides for better comfort, because it can move the air at a slower pace.

Variable Stage or Modulating: A variable-stage or modulating furnace modulates the speed and heat output based on the temperature outside and the desired comfort level. This furnace only works as much as you need it, making this type the most energy-efficient type of furnace.

What Is AFUE?

AFUE, or Annualized Fuel Utilization Efficiency, is a measure of furnace-heating efficiency. The higher the AFUE, the more efficient the furnace.

How Much Money Can a New Furnace Save You?

Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit's AFUE value and compare it to a newer, more efficient system. You can even customize it to better match your home's system for a more accurate calculation.

What Size Furnace Do I Need?

We can calculate the correct size furnace for your home. The number of BTUs, or British Thermal Units, needed to heat your home is dependent on a number of variables. Contrary to what you might think, a bigger furnace may not necessarily mean more heating power for your home. Call us at Ballard Natural Gas, and we can set up an appointment to calculate the furnace size you might need.

“Justin performed excellent maintenance on our home furnace. We’re very happy with the service provided to us by Justin and Ballard Natural Gas.”

– Joseph G.

“As always, Justin’s work on my annual furnace maintenance was exemplary. He was efficient and courteous. He has serviced my furnace before, and I always have confidence that the work was done correctly and that any recommendations he has are legit (even though I can’t afford to do them right now). He is the best.”

– Diane D.

“Justin just completed our annual service of our gas furnace and A/C system, everything checked out and he left everything clean, kudos for him putting up with our barking dog!”

– John D.

“Our furnace stopped working on Saturday, we had someone here first thing on Monday and a new furnace by Tuesday afternoon. Really impressed with the responsiveness and helpfulness of everyone we worked with. Everything was really clear and I didn’t feel pressured to go with any certain product, but did feel like I had the information needed to make my own decision.”

– Jacqueline D.

“Conrad’s service is five times 5 stars!!! Ballard has been keeping me warm for decades. Really appreciated todays service call since furnace was out on a very cold day”

– Kerry K.

“Bitter cold weather is in the forecast, so I decided not to procrastinate any longer and have the furnace serviced. (In last year's record cold the furnace died and there was no heat for days; Ballard Natural Gas Service was the only HVAC business that returned my call and came out to fix it. So grateful!)

When HVAC diagnostic tech George Watts arrived and checked the furnace in the crawlspace, he discovered issues with the condensate pump; there was also water under and around the furnace. Not good. George quickly fixed the problem, explaining each step and answering my questions. If this had not been addressed immediately, there could have been serious problems with the cold weather ahead.

I rarely post online reviews, but this is the exception: Ballard Natural Gas Service came through for me when my furnace failed last year, and now they’ve come through again, just before this major snow/cold snap in Seattle. George Watts is exceptional, not only in his expertise but in his kindness and concern. Highly recommend!”

– Helen H.

“They kept us informed as the tech was on his way. Tech was timely and very professional. Same guy we have had before which is reassuring. Performed the maintenance as requested and made one suggestion which we decided to do. Professional all the way around. We will continue to used Ballard”

– Alan G.
