It’s important to keep your furnace receives regular maintenance to ensure that it’s working properly and efficiently. Routine maintenance can also extend the life of your heating system by several years. Ask about our annual maintenance agreements that cover your plumbing, heating, and cooling systems and save you money. A furnace that has been neglected may be working too hard, which can result in inconsistent air temperatures in your Minneapolis area home.

We asked This Old House plumbing and heating expert Richard Trethewey to show us the proper steps that a service professional would follow for an oil-burning forced-air furnace; the basics on a gas system are similar. In both, fuel is mixed with air and ignited, heating a sealed chamber. Fresh, filtered air then blows across the outside of the hot chamber and into the heating ducts. (Homes with radiators have boilers instead of furnaces. These heat water instead of air, but the annual checkup is similar.) In all, the dangerous exhaust from the combustion chamber is vented out a flue or chimney.
If you pull out your home’s air filter, hold it up to a light. If you can’t see light coming through it, it’s most likely been a while since your last heating service, and likely time to get a new one. If it’s a simple disposable air filter, just replace it with a like-size new one. It’s also a good idea to write down the date you installed the new filter, so you know how old it is next time it needs to be replaced. Check the filter packaging to see how long the new air filter is supposed to be used.
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!

When a furnace maintenance is performed a combustion analysis should be performed to identify any problems that couldn't be found by a visual inspection. You want to know what the Carbon monoxide level your furnace is producing as well as the oxygen/CO2 levels and stack temperate. The analyzer will also give you a calculated efficiency rating with the information the analyzer receives. You should have >100ppm of Carbon monoxide output during normal operation of your gas furnace. When you have higher numbers or CO numbers increasing during operation their is a problem with the furnace the technician should then find the cause of. This is just a brief explanation I'm trying to get across to those who get their furnace maintained and to those who don't! Check to see if anyone in the company has a NCI certification for carbon monoxide/combustion analysis.
