There’s a common misconception that you can save money by shutting the vents (supply registers) in rooms that aren’t being utilized. Resist the urge to close too many, as doing so can actually increase the pressure in your furnace, making it work harder to heat your home. This can lead to failed blower motors, mold or mildew in your ductwork, damage to the compressor, a cracked heat exchanger, and other problems. What Does a Furnace Tune-Up Include?
No one wants to be stuck in the dead of summer with a broken air conditioner, or in the cold of winter with a broken furnace or boiler. That’s why we’re available any time of day to make your emergency heating and air conditioning repair and get your system up and running as quickly as possible. We’ll show up on time, in uniform and ready to make your HVAC repair right the first time.
“Walter Zainey started the Greenwood Furnace Co. in the Greenwood neighborhood of Seattle in 1918 and quickly built a reputation for providing quality products and services. For years we believed Greenwood began in 1921 but only recently, May of 2017, Walter’s granddaughter shared a newspaper ad from 1968 showing that Greenwood was actually founded in 1918! When your company goes back 100 years you are bound to have mixed messages about the history but we now have an accurate founding date and founder. Thank you to the Zainey family and especially Jacklyn for taking the time to share the story with us. I am sure Walter Zainey would be proud the heritage he created is still living on.
For starters, once a year, vacuum out the area around the furnace’s blower. If possible, also slide out the fan unit, clean each fan blade with a toothbrush, and then vacuum with a brush attachment on a vacuum cleaner. While you’re at it, look for oil ports on the motor, normally located near the motor shaft. If the motor has these, apply two to three drops of non-detergent motor oil into each port (you may have to remove a cover plate to do this). Though most contemporary motors don’t require lubrication, do lubricate motors with oil ports once a year. For more about maintenance, see Maintenance Checklist for Central Heating Systems.
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!

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.
