Choosing the Right Gas Furnace for Your Seattle Home

A Step-by-Step Guide by Seattle Air Superior

Installing a new gas furnace is a major investment for any Seattle home. Not all gas furnaces are created equal, so it’s important to consider factors like efficiency, capacity, and features when selecting the right model for your needs. Here are three key things to keep in mind when choosing a new Seattle furnace installation:

The first decision you’ll need to make is the type of fuel your furnace will use. The most common options are natural gas, propane, and electricity. Natural gas is widely available and generally the most cost-effective choice, while propane can be a good alternative for homes without access to natural gas lines. Electric furnaces are also an option, although they may be more expensive to operate in the long run.

Ensuring that your furnace is properly sized for your home is important for efficient and effective heating. An undersized furnace may have difficulty regulating a pleasant temperature, while an oversized unit will cycle on and off frequently, leading to increased wear and tear and reduced efficiency. To determine the appropriate size, consider factors such as your home’s square footage, insulation levels, window types, and the number of occupants. We can perform a thorough heat load calculation to recommend the ideal furnace capacity for your specific needs.

A furnace’s efficiency is evaluated based on its Annual Fuel Utilization Efficiency (AFUE) rating, which represents the percentage of fuel that is converted into usable heat. The higher the AFUE rating, the more energy-efficient the furnace. Investing in a high-efficiency furnace can lead to significant savings on your heating bills over time. Look for furnaces with an AFUE rating of at least 90%, which is considered high efficiency. Some models even offer AFUE ratings of up to 98%, providing exceptional energy savings and reduced environmental impact.

Seattle Furnace Installation: DIY vs. Professional Services

Installing a new gas furnace in your Seattle home can be a big project. While some handy homeowners opt to do it themselves, there are distinct advantages to hiring professional furnace installation services.

For fireplace, Scheduling was easy and person arrived with a heads up. However, within a couple minutes, the technician realized that all the fix needed was a new battery and asked for $150 to replace batteries (which I provided). He asked for being able to diagnose battery replacement as his skills. They helped resolve so I give them two stars but i felt that I was cheated and held to pay more than a reasonable price. I would not recommend these guys again or use them again.

Nathan came in and trouble shot the issue within 5 mins then he figured out it’s the wire connection problem what caused the fireplace not working properly. He spent another 5-10 mins to fix it and the fireplace then works back to normal. It was pretty efficient and accurate problem solving, I like that and would like to recommend him to whoever needs the help.

Common Gas Furnace Problems and How to Repair Them

Gas furnaces are generally reliable appliances, but they can encounter issues after years of wear and tear.  

  1. Pilot light won’t ignite – First check that the gas valve is turned on. Next, clean the thermocouple and adjust the pilot light. If needed, replace the thermocouple.
  2. Burners fail to light – This could indicate a problem with the igniter. Try cleaning it, check the flame sensor, and replace the igniter if faulty.
  3. Furnace keeps shutting off – The furnace may be cycling due to a dirty filter, closed vents or a tripped safety switch. Clean or replace the filter, open vents and reset the safety switch.
  4. Noisy operation – Excess noise usually comes from a faulty blower motor or loose ductwork. Tighten duct connections, lubricate the blower motor or replace if needed.

Schedule annual furnace tune-ups and stay on top of minor repairs to maximize the lifetime of your Seattle furnace installation. Replacing key components as needed can often extend the lifespan of an older unit.
