Choosing a Furnace in Eastern Washington or Northern Idaho

Modern furnaces are powerful, quiet, and energy-efficient appliances that deliver comfort to every room in your home. They not only provide warmth but can also help improve your indoor air quality (IAQ).

Here are a few factors to consider when purchasing your next furnace:

1. The Right Size—Our heating and cooling experts will install a correctly sized furnace to fit the square footage and layout of your Spokane home. Doing so ensures you get the most benefits in terms of comfort and operating costs.

2. The Right Model—A smaller household can get away with a single-stage furnace that switches on and off based on the thermostat setting. But larger homes will benefit from a two-stage furnace or variable-speed furnace. These models quickly respond to any changes in the temperature and will keep your home at a more consistent temperature.

3. The Right Efficiency—Newer gas furnaces have an annual fuel utilization efficiency (AFUE) rating upwards of around 98 percent, which means they can convert 98 percent of the fuel they burn into energy. A higher AFUE rating creates greater efficiency.

4. The Right Fuel—Most homeowners in Spokane rely on natural gas to fuel their furnaces. If you don’t have access to a natural gas line, propane or oil are the likely alternatives. You can also consider an electric furnace, but be prepared to pay more in operating costs.

Our financing options and complete warranty packages make it convenient for you to pick out the perfect furnace for your home and budget, subject to approved credit.

“Our furnace declined our polite invitation to heat our home once things started getting cold a couple weeks ago. I was able to figure out the fuse on the control board had blown. I attended a few quick courses at YouTube University and was able to rule out the thermostat wire, but that was all my 30 minute degree was worth. And the fuse kept blowing each time we tried to call for heat. We called in a different HVAC company to fix the issue, but after 2 techs made 3 different trips, they had reached 3 different conclusions as to the cause of the issue, all of which turned out to be wrong. Oh, and their quoted prices for the incorrect solutions were astronomical. Anyway, we called Trademark and KC came out right about noon today, and by 3:30 he had figured out the problem, which was a sneaky little short in one of the safety limit switches. Finally, the mystery was solved! KC should be awarded the honorary title of Chief Inspector, because he did some masterful detective work today. Oh, and he seems like a pretty nice dude. Because of him, you’ve got a new loyal customer for future HVAC maintenance and repairs.”

“Called with issue with furnace. Explained furnace was only 3 1/2 yrs old. They said they would have tech come out and diag. Said they could have someone out today and within a half hour of scheduling tech called and said he could be there in 15 minutes. Tech diagnosed furnace and part was still under warranty. Had part on truck and furnace was running within an hour with just a charge for labor. Excellent service.”
