Do not try to do DIY gas furnace maintenance or tune-ups yourself. In addition to being dangerous, this may also violate the manufacturer’s warranty. Let properly trained and experienced technical staff perform all gas furnace preventative maintenance. Regardless of your DIY talent, trying DIY furnace maintenance is fraught with hazards and risks to your heating system—and yourself.
Furnace tune ups should take anywhere from 45 minutes to hour and a half, depending on what the technician has to deal with when he gets there. I was a heating and AC professional for over 10 years and I had tune ups that only took me 30 minutes, and others where it seemed like I had to practically disassemble the entire furnace, clean, then put back together. Every call is unique. However, it's important you trust your contractor. Your instincts are more accurate than you probably give yourself credit for. I don't remember a tune up ever going less than a 1/2 hr in my 10 years of experience. It just takes time to setup, take down, and perform the actual maintenance. If you figure a minute per inspection point, it should have at least taken half an hr. I've showed up to furnaces that look flawless, and I still take them apart and clean them because that's what the homeowner paid me for. If there is even a hint of a cracked heat exchanger, get a second opinion. There are scams out there, and unfortunately a 20 minute inspection wouldn't reveal that. Have whomever is making the claim show you via camera or by physically removing the combustion chamber from the furnace and showing you. As weird as that sounds, I've removed heat exchangers out of furnaces just to prove that there was an issue. A cracked combustion chamber can be a serious issue, so the fact that he said it should be fine says either he doesn't know what he's doing or he's not being truthful, or both. It's not that cracked heat exchangers are leaking carbon monoxide, it's that they can. It's the potential that makes it dangerous. Hope this helps!

The thermocouple is a copper rod that the pilot flame heats-up. When it gets hot enough, the thermocouple signals that there is enough heat to burn the gas fuel being released into the appliance—and so it allows the gas to be released to the burners. In some cases where the pilot light won’t stay lit, the thermocouple needs to be adjusted or replaced. This is generally a job for a professional.

Seattle furnaces can run nine months of the year. Based on the average temperatures in our area, if you compared running your furnace to a car it would get the equivalent of 1.8 million miles over its expected lifespan of 15 years. Your heating system will work hard for you, but like your car, doing routine and regular maintenance will keep it running smoothly, avoid problems, and keep your warranty intact.
This job involves removing the access panel, loosening a couple of bolts that hold the blower motor at the proper tension, and adjusting its distance or realigning the belt. In many cases, it’s a good idea to remove the belt and buy a replacement at a home center. Last, when reinstalling the belt, be careful not to over-tighten it; this can wear out the motor bearings.
To keep your natural gas furnace operating efficiently, you should have at least an annual tune up. Natural gas furnace preventative maintenance will help avoid operating problems. When issues are addressed early on, it’s more likely that they can be resolved with minimal cost. Worn out parts and clogged filters that happen over time can lead to more significant equipment failures.

Brands particularly have an impact on that price. A Goodman electric furnace, will only cost about $2,100 for the unit and labor. On the other hand, a Trane oil furnace may cost up to $9,000 all things considered. Our Furnace Installation Cost Guide can give you a better idea on both the general cost and the differences for brands like Amana, Bryant, Coleman, and others. The brand also plays into the repair cost for your furnace.
